Kennametal has expanded its replaceable drill offering for KenTIP FS modular drill series with the
new FEG insert for flat bottom hole applications. Applicable in steel, cast iron, and stainless steels,
the FEG insert eliminates end milling operations and completes a task in a single operation, saving
time and tooling costs.
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.
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.
