Drilling flat-bottom holes is a challenge. So is drilling on inclined or curved surfaces, drilling into cross holes, drilling stacked plates, and drilling into cross holes, stacked plates and castings and other rough surfaces. Not anymore. Leveraging the success of its KenTIP FS modular drill, Kennametal has developed a unique insert geometry (FEG) that streamlines many of these types of applications and simplifies the drilling of counterbores and pilot holes as well.
“The FEG insert is so versatile, you can use it for nearly all your drilling applications”, says Georg Roth, Kennametal’s Global Product Manager of Holemaking for Modular Drilling Tools.
Get to the point
Conceptually, the FEG geometry design is simple. It features a 180° cutting edge, and a conical center point, which acts as a pilot to provide exceptional hole position and straightness. Corner chamfers serve to protect the cutting edges and reduce exits burrs. Four margin lands provide stability when breaking into interrupted cuts and cross-holes. And Kennametal’s KCP15A grade uses a nano-structured AlTiN coating and fine grain carbide substrate, providing both toughness and wear resistance when drilling steel, stainless steel, and cast iron.
The diameter range covers 6.0 – 26.0 mm (0.236 – 1.024 in.) and drilling depth of up to 12xD is possible depending on the KenTIP FS modular drill body.
