Kennametal and The Tool Crib are proud to offer two new series of drills that have been designed for high performance applications in production environments. The new HPX carbide drills are for use in ISO P (Steel) and K (Cast Iron) applications. The SGL carbide drills are for use in ISO M (Stainless) and S ( High-Temp Alloys).
The HPX carbide drills comes in 3, 5 and 8 x diameter lengths. The cutting edge of the HPX has been designed to reduce build-up and chipping. The point angle is 140 degrees to provide centering stability, aid in chip formation at the center and reduce thrust. There are two margins on the lands for increased stability and lower friction. These tools also feature an ultra polished chip flute to improve chip evacuation and reduce heat. The end result is a tool that can run faster and longer in jobs where productivity is key.
The other new series developed by Kennametal is the SGL family of carbide drills. The SGL carbide drills are designed specifically for use in stainless steels, nickel and cobalt based alloys. They have a patented point geometry and are treated with a monolayer PVD AlTiN coating. They are offered in 3, 5, 8 x diameter lengths as well as a deep hole series in 15, 20, 25, 30 and 40 x diameter. Kennametal can also make custom step drills using the design.
A key goal of the new design is to reduce build up on the cutting edge which allows the tools to last longer and run at higher cutting parameters. The patented point reduces the pressure required at the center of the tool, while the edge features reduce buildup and make chip flow better. By effectively making the drill more efficient, it also reduces the stress introduced into the part material. This then reduces the amount of work hardening that occurs when producing the hole. By limiting the increase in hardness, secondary operations like reaming or tapping can also be improved.
