We announced the release of our new EXOCARB® ADF drills. The ADF combines two operations in one for the drilling of inclined surfaces and counterboring applications.
The ADF was developed with an “all-purpose” concept for superior versatility, reliability and quality for flat-bottom holes. Machining a flat hole traditionally required the use of an end mill and a drill. The ADF enables one-step drilling thereby simplifying machining time and tool management. The drill’s balanced point form improves precision and minimizes the shifting of hole position. Its sharp cutting edge results in low cutting force to minimize burrs even in thin plates. With a wide chip room geometry, trouble-free chip evacuation can be achieved. Furthermore, with the addition of OSG’s new proprietary EgiAs coating, tool life can be prolonged with excellent heat and wear resistance.
The ADF is engineered for a wide variety of drilling applications including inclined surfaces, curved surfaces, counterboring, eccentric holes, thin plates, etc. It is suitable for common materials such as carbon steel, alloy steel, hardened steel (up to 35 HRC) and cast iron. Standard types are available in diameters from 2 to 20 mm; long types are available in diameters from 3 to 20 mm).
David Whitmire, OSG district manager, has been covering a sales territory in Texas
and Oklahoma for 9 years. He has witnessed both the best and worst days of the energy
industry. Since the price of oil per barrel has recently reached record lows,
our economy and oil field manufacturers have been severely affected. An
increasing number of layoffs and downsizing at companies has occurred in the
area. During this down time, some oil field manufacturers started to do their
homework by reconsidering their machining processes as an avenue to cut costs.
This has opened up some new opportunities for OSG in David’s territory.
One of David’s customers is
a large pump housing manufacturer in the oil field industry. During the
industry slowdown, the company wanted to be proactive, so they invited OSG and
a local distributor to host a tap trouble shooting seminar. During the seminar,
David showed them the OSG EXOTAP® A-Tap® and EXOPRO® Mega Muscle® drill videos.
These videos drew a lot of attention as they showed A-Tap® and Mega Muscle® products
surpassing speeds and feeds of competitors’ tools. This company produces 50 to
60 parts after spending over 625 hours machining per month. David decided to
perform tool testing with his local distributor to help the company improve
productivity and cut costs.

Competitor B’s Cam Drill (2.5 IPM)
7. 22mm PHOENIX® PXD Exchangeable Head Drill 300 (SFM
and 21.2 IPM) vs. Competitor B’s Cam Drill (2.8 IPM)
Test 1 demonstrated a significant advantage of the
A-Tap®. Even if it ran at the same speeds and feeds with the competitor’s tap, the
A-Tap® was able to produce 25% to 40% more pump housings and to reduce costs by
$22 per tool versus the competitor’s tap.
Tests 2, 3, 4 and 5 showed that OSG’s taps and
drills ran at faster speeds than the competitors’ tools, and the A-Tap®, VXL
Tap and Mega Muscle® products were able to reduce the cycle time by 23 minutes.
In addition, the A-Tap® and Mega Muscle® machined 5 times more parts than the
competitors’ tools did.
Tests 6 and 7 have not been completed, but David is
confident that the WDO® drills and PXD drills will reduce the cycle times even
more. By using OSG’s taps and drills in their operation, David predicts that
the company will be able to reduce at least 21 hours of machining time per month!

The 41st Annual Barrett-Jackson Auction located in
Scottsdale, AZ. is no ordinary auction. It is “The World’s Greatest Collector
Car Events™,” which captures the essence of a passionate obsession that
collectors and enthusiasts share throughout the world. I was fortunate enough
to attend the auction where I saw lines of gorgeous vehicles and watched a
$50,000 bid shoot up to $250,000 in 30 seconds, all for a used car!
Many of the high performance vehicles displayed in the auction had employed the exhaust manifold design, also known as the exhaust header design, for car tuning. Exhaust headers are one of the easiest
performance because they make
it easier for
the engine to
gases out of
the cylinders. Most headers
for naturally aspirated
in mild steel, while headers for turbo charged engines, on the other hand, are often manufactured in 304 Stainless Steel.
Recently, one of my customers from Las Vegas, NV, who is a header plate manufacturer, called regarding a drilling operation in 304 Stainless Steel. He had been using standard cobalt drills but was not able to produce a good hole and had encountered some abnormal sound during the operation. To solve the problem, the customer had to pay to water jet at $40
per part. Not only were they losing money, they also had to extend their lead-time by using an outside vendor.
After a careful examination of the application, I recommended OSG’s EX-SUS-GDR drill from the EX-GOLD® series. OSG’s EX-SUS-GDR drill is manufactured from premium high-speed steel, ideal for stainless steels, mild steels and aluminum alloys. The addition of OSG’s TiN or TiALN coating improves wear-resistance and prolongs tool life.
During the first test, the EX-SUS-GDR drill also encountered the abnormal sound, producing a long thick chip and breaking after the second hole. I was concerned with the chip formation while the customer was concerned with the sound, breakage and no parts. I knew that once we had the chip formation under control, the sound and tool life would increase. So, starting off slow, we increased the 10 mm EX-SUS-GDR drill to 480 RPM with 0.009 IPR. With these simple adjustments, we were able to produce 120 holes and finish the job with no trouble whatsoever.
At the end of the day, this customer was not only able to produce holes efficiently and effectively, but they also eliminated the need to utilize an outside vendor, reducing lead-time and cost per part.
The success of large auto events like the 41st Annual Barrett-Jackson Auction depend on having consistent, working parts in all of their cars. By using our EX-SUS-GDR drill combined with the right cutting tool strategy, our customer was able to produce parts more efficiently, allowing them to continue to supply cars with headers that hold up under the spotlight.
The versatility of the EXOCARB® WDO Drills, EXOPRO® XPF Taps and HY-PRO® VGx End Mills makes this dynamic trio an unstoppable force.
Whether drilling, tapping or milling, the unique design of these tools allows them the ability to machine a wide range of materials from cast aluminum and carbon steels to die steels and hardened materials, making them an ideal solution for job shops and manufacturers requiring flexible tooling options.

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.
