If there’s one thing that Vicki’s tenure with OSG has taught her, it is that hard work and dedication do not go unnoticed.  But those things do not stop at the doors of OSG for Vicki. With her main focus being her three children and raising them to stay on the right track, she recognizes how much discipline and organization it requires to neglect neither work nor her family.


Vicki admits that her mom is her true hero, looking to her for inspiration. “She came to the United States at the age of 18 after marrying my father without any family of her own. She learned the language, raised two children and ran the household, always while working a full time job. She is an amazing woman, wife, grandmother, mother and friend.”


Although Vicki’s personal goal is to live a healthier life through food and exercise, her passion will always be her family.



HELIOS® Drill: No Pecking or Coolant-Through Required

Written by OSG

David Whitmire, District Manager

There are many things that can hold job shops back, from tight tooling budgets to non-coolant through machines.  On a recent visit to a customer located in Overton, TX, the owner of a medium sized job shop had expressed a major concern regarding one of his drilling operations.  The OSG solution easily solved both these issues and more.


The customer was trying to drill a 7/16” diameter hole, 9” deep in alloy steel using a competitor’s high-speed steel drill, running at 525 RPM and a feed rate of 0.003 IPR. With that tool, at those parameters, they were pecking every 0.050” to get the chips out of the hole, which added considerable time to the process; it was taking approximately 22 to 25 minutes to drill just one hole.

Based on the cutting conditions and the trouble they were having with pecking, I knew that this was a great application for the OSG HELIOS® Drill. OSG’s V-Series HELIOS® drill is a high-speed, cobalt drill designed for deep-hole drilling. The unique design and patented technology of this drill gives it the ability to process deep holes without the use of internal coolant supply. State-of-the-art flute design improves chip evacuation, making it feasible to drill up to 20D without pecking. By utilizing OSG’s WXL® coating, the V-Series HELIOS® drill can handle a wide range of materials with up to three times greater wear resistance versus conventional coatings.


Upon explaining the benefits of this high performance drill, informing the customer that we had a HELIOS® 7/16” x 20D drill available off the shelf with the required flute length and that we could run it at 837 RPM and 0.008 IPR, he immediately ordered two test drills.


As soon as the drills were delivered, I received a call from the machine operator wanting to verify the speeds and feeds before running the drills. After I confirmed that 837 RPM and 0.008 IPR was indeed accurate, his first comment was that he didn’t think the HELIOS® Drill would make it through one hole, but he proceeded with the testing based on those parameters.  


When the operator couldn’t hear any noise on the first hole, he was sure the drill was already broken, but to his amazement, the drill was still in the machine when the cycle ended. Even then, the operator continued to be skeptical. It wasn’t until the HELIOS® drilled 100 holes and all the parts were completed that he was finally sold on this dynamic drill. The operator himself admitted that the HELIOS® Drill had dramatically reduced cycle time and saved three days of machine time alone.

When all was said and done, by eliminating all the pecking required with the other drill, we reduced the total drill cycle time from 25 minutes to 1.5 minutes per part. This didn’t even take into account the cost savings, which was estimated to be nearly $30,000 based on the 5,000 holes the shop was scheduled to drill.


OSG’s HELIOS® drill was able to help this customer improve their machining process and produce more parts off the machine per day. Plus, the HELIOS® Drill is a fraction of the price compared to solid carbide drills, making it a more economical solution with the flexibility to be used on non coolant-through machining centers.

Stable, Chatter-Free Milling with UVX

Written by OSG

Shane Soberg, District Manager

As you may already know, the aerospace industry is constantly evolving, which is why OSG has dedicated a tremendous amount of resource into the development of new technology for this industry. One such innovation is the EXOPRO® UVX-SUS End Mill, designed for maximum metal removal rates in stainless steel, titanium and high nickel alloys.


Unlike traditional geometry end mills that have a difficult time with harmonics and chip removal, the unique 4-flute variable helix design of this UVX end mill allows for chatter-free milling and facilitates excellent chip evacuation, leading to improved tool life.



Recently, one of my customers from Minneapolis, MN was running into some issues with a part they were machining. The 15-5 stainless aircraft part required a 4” long slot at 0.587” deep.  At the time, they were using a traditional 5/16” diameter, 4-flute TiAlN coated end mill from a competitor.  The end mill had a 0.015” corner radius, slotting at 0.0625” depth of cut per pass.  Running at 4,800 RPM with a feed rate of 10 IPM, they were getting 10 passes per part and producing 10,000 parts per year.  Cycle time was 5 minutes and tool life was only 14 parts per end mill, which were disappointing numbers and showed very little profit for the customer. 

I was confident we could reduce the number of passes and decrease cycle time using the EXOPRO® UVX-SUS End Mill, so I explained the benefits to the customer. Striving to improve their machining process, they gave us the green light to begin testing, so we ordered two 5/16” diameter UVX end mills with a 0.015” corner radius.


We changed the CNC program to take three depth of cut passes at 0.150” and one at 0.137”. After decreasing the speed from 4,800 RPM to 3,000 RPM and increasing the feed from 10 IPM to 25 IPM, we let the UVX end mill run its course, milling so quietly that the only sound we heard were the chips hitting the door on their Makino.


I followed up with a visit the next day to see the final results of the test and was greeted by smiles. The EXOPRO® UVX-SUS End Mill was not only able to reduce cycle time from 5 minutes down to 1 minute 47 seconds, but it also increased tool life from 14 parts per end mill to 64 parts per end mill, a more than 400% increase. Based on those numbers, this customer would see $38,000 per year in cost savings and $18,000 in tool cost reduction on just this part alone. The customer said it best, “Wow!”


Since then, they started to run the UVX end mills in other applications as well and have been able to reduce cycle times all around, allowing them to bring in new work, thus providing growth and expansion for the company as a whole.


Although part designs and materials continue to become more and more complex, especially in the aerospace industry, the goal to remain profitable will always remain, as will OSG’s pursuit to develop the innovative tooling to keep up; case-in-point, the EXOPRO® UVX-SUS End Mills.

Much like his hero and inspiration, Arnold Palmer, Tim O’Sullivan is driven by hard work and dedication.  While Palmer rose from a blue-collar background to dominate a sport traditionally ruled by the white-collar upper class, Tim has risen up the ranks at OSG, learning that his hard work and determination would open doors to new opportunities.


Recently starting back at school to pursue a Master’s Degree in Project Management, Tim spends whatever free time is left with his family or golfing. While he also enjoys riding his bike on the trails and cooking up new recipes, he admits his true passion is golf.


“I love to golf as much as I can during our short golf season.” His personal goal is to record at least one birdie in all 50 states, Mexico and Canada. “I currently have eight off of the list, so I still have plenty of travel and golf left to accomplish. Next up is Ohio.”



OSG Continues to Support St. Jude

Written by OSG

We hosted our second BBQ of the season to benefit St. Jude today. This is just one of our many fundraising efforts for St. Jude that we host throughout the year. Some of our other events include bake sales, raffles, silent auctions, bingo, bags tournaments, cookouts and more.


But this isn’t just an excuse for us to host fun events throughout the year, and we didn’t just pick a random charity out of a hat to support.


Over 13 years ago our employees banned together wanting to do something more for the greater good. After researching a handful of charities, it was put to a vote in order to find the charity that most represented OSG as a whole.


With overwhelming solidarity, St. Jude Children’s Research Hospital won the hearts of the employees with their mission to prevent and cure pediatric cancer, and other deadly diseases, through research and treatment. Throughout their 50-year history, St. Jude has successfully pushed the childhood cancer survival rate from 20 percent to 80 percent, sharing all the breakthroughs they make to doctors and scientists worldwide.


The money OSG raises goes directly to the cost of treatment, travel, housing and food for St. Jude families, as St. Jude never bills them for any of these costs.


“It’s wonderful how many people recognize St. Jude and are willing to do what they can to help contribute,” stated Sherri Tiani, Corporate Controller for OSG. Since our commitment to St. Jude in 2006, OSG employees, along with OSG’s company match, have raised well over $100,000 for St. Jude Children’s Research Hospital.


So while a small donation for a bake sale or BBQ may not seem like a lot, it truly adds up in the end, making a difference to the children and families who need it.

AERO-F for Automotive

Written by OSG

By: Ronald Portwine, District Manager

With the introduction of the HY-PRO® AERO-F Tap, I have attacked many different applications and have found it to be a great tap for unique materials that are not listed in the work material application guide. With its cutting geometries and TiN coating, OSG’s AERO-F Tap has won over several accounts, from fastener manufacturers to job shops.


One of these accounts is a OE manufacturer for Ford, Honda, GM and Toyota, making automotive timing gears and sprockets, as well as aftermarket gears for most automotive manufacturers. The end user has two facilities in Arkansas, one of which makes camshaft drive gears for the GM V6 and V8 engines. These engines have dual overhead camshafts that are used in most light trucks and cars. They had recently signed a new contract to produce over 3 million gears for GM, so I decided to pay them a visit.


At the facility, the Machining Engineer, Keith Hann, and I discussed the GM camshaft gear they had in production. Running on a four-head Brothers CNC machine with a rotating table loaded by a robot and set up on a conveyor system, the camshafts were being manufactured from a powdered metal at around 24 – 28 HRC, after heat treatment. The hole they were tapping was 5 mm in diameter with a tolerance of +/- 0.12 mm for the M6x1 D5 thread.


Keith informed me that they were using a competitor tap and were getting 12,000 holes per tap on average. He did not believe there could be any improvement made on the current hole-count, but I was not swayed by his disbelief. I asked him for an opportunity to put the HY-PRO® AERO-F Tap on the spindle to prove otherwise.

Knowing they were running four tapping heads, I ordered four AERO-F taps (EDP number 1111500705, M6 x 1 D5) for testing. We loaded the four taps and zeroed the counter. After verifying that the thread gage was good, the finish was correct and the machine was functioning properly, we watched the taps produce about 1,000 holes, and then left the rest to the operators.

I contacted Keith after a couple of days to check on the performance of the AERO-F taps. He informed me that the hole-count was 30,000 plus…and still going! He was truly impressed and ready to make the switch, but his amazement didn’t end there.


Upon receiving a quote from his distributor, Keith questioned the cost. He thought maybe he was not given the correct price because each AERO-F Tap was only a couple dollars more than the competitor’s tap. I assured him that it was correct. Keith acknowledged that it was well worth the cost, and could easily justify a switch to the HY-PRO® AERO-F Tap.


When all was said and done with the test, it turns out the AERO-F taps actually got close to 40,000 holes anwere only pulled because one of the four taps failed. With over double the tool life, Keith’s team was able to dramatically increase production and reduce down time.

The HY-PRO® AERO-F tap has become my favorite go-to tap because it has proven to be a low cost, high hole-count performer for my end users. Once the AERO-F tap has been placed on the spindle, it proves itself as the best tap for the job time and time again.
