For milling pre-hardened and hardened steels, you need an end mill that won’t wear down. OSG’s premium high performance carbide end mills, the EXOCARB® WXL® and the EXOCARB® WXS®, are specially designed for rigidity and performance in even the toughest materials and milling applications.
The WXL® is specifically tailored for nonferrous materials and mild steels up to 55HRC, and can withstand up to 1100 degrees Celsius. The WXS®, on the other hand, is made for hardened steels like D2, A2, S7, H13 and CPM, milling up to 65HRC and able to withstand up to 1300 degrees Celsius.
For added strength, our WXS® and WXL® have thicker core diameters and are made of the hardest carbide possible for incredible wear resistance. The higher coating oxidation temperature and hardness keep these end mills performing long after the competition wears out.
Ideal for the Mold & Die industry, the WXS® and WXL® utilize high precision geometry with a +/- 5um radius tolerances for both corner radius and ball end mills, eliminating the need for benching and reworking.
With hard carbide materials combined with high precision, the EXOCARB® WXS® and WXL® are the top hard milling solutions.

We’re taking tooling to Texas for this year’s HOUSTEX Show. Located at the George R. Brown Convention Center in Houston, HOUSTEX runs February 24 through 26, 2015 and features the latest innovations in manufacturing technology, speakers, and interactive product demonstrations.
OSG will be featuring a variety of tools at this year’s show. To showcase our newest innovations, we’re featuring our all-purpose EXOTAP® A-TAP designed to excel in a wide variety of materials and applications and the EXOPRO® WHR-Ni, a spiral point tap for nickel-based alloy applications. We’re also bringing the EXOCARB® WDO Drill series, our high performance coolant-fed carbide drills for ferrous and non-ferrous materials, and our EXOPRO® UVX-Ni End Mills with a variable helix design to reduce vibration in difficult-to-machine materials like nickel alloy. Plus, we will showcase some of our indexables from our high performance PHOENIX series, such as the multifunctional PSE shoulder cutter and ultra performance PHC cutter for maximum metal removal rates.
We’re excited to be a part of another great HOUSTEX show! Come down and see us at Booth #258. Register today.

“Inconel – oh no! It’s a tool killer. It’s too tough and nasty to cut!”
This is a common
customer reaction when dealing with Inconel. It is a difficult material, but
should it make shops run for the hills? Absolutely not! Common in the aerospace
industry, Inconel is one of the toughest high temperature resistant materials.
However, with the correct tool, it too can be easier to machine.
One of my
customers working with Inconel was in need of a 5/8” end mill for a new project involving an aerospace engine part that they were quoting.
After examining the job, we realized that removing all the material would be
the biggest challenge.
For their slotting operation, I recommended OSG’s EXOCARB® Aero Rougher. Many people in the industry are familiar with older end mill designs such as the Corncob Rougher and Knuckle End Mill. Our Aero Rougher, however, is not just a typical Corncob Rougher. It is specially designed for maximum metal removal in exotic high temperature materials. The uniquely configured serrations on the cutting edge reduce friction, thereby generating less heat and requiring less horsepower than standard or variable helix carbide end mills. In addition, the combination of the shallow profile serration and the 45° helix provides a much smoother surface finish.
With it being a new project, my customer needed to make profit but also keep costs down in order to win the bid. To determine if the Aero Rougher was their best choice, we tested it against two other competitors that had a variable design.
To begin the test, we used the OSG recommended speeds and feeds for the application, 520 RPM at 2.7 IPM. With the majority of the cuts being a slot, we recommended 0.156” on the depth of cut (DOC). In the end, the operator was delightfully surprised when he saw the results of the OSG tool performance. After several trials, the customer was able to push the Aero Rougher to 0.200” DOC. OSG scored lower in cost and provided the customer a completed part. The competitors, on the other hand, were not even able to finish the job.
In today’s competitive market, OSG’s EXOCARB® Aero Rougher is able to provide users the ability to run tools with higher feed rates and deeper depths of cuts for reduced cutting time. It not only handles the tough and the nasty, but it helps eliminate stress when working with Inconel.

Heat resistant super alloys like Inconel 718 have low
thermal conductivity, causing rapid and extreme wear of the cutting tool due to
concentrated heat on the cutting zone. To combat against this issue, OSG
developed the EXOPRO® UVX-Ni End Mill. This high performance end
mill has a five-flute variable helix design to facilitate excellent chip shape
and evacuation, while the tapered core and special edge prep rigidity protects
against wear. These features allow for consistent, stable machining in side
milling, pocketing and slotting operations.
Check it out in action to see the difference!
