Replaceable Drill Tip Cuts Tooling Costs and Eliminates Process Steps
Kennametal’s flat-bottom FEG insert for the KenTIP FS modular drill series eliminates end milling operations and completes a task in a single operation, saving time and tooling costs. Applicable in steel, cast iron, and stainless steels.

Drilling flat-bottom holes is a challenge. So is drilling on inclined or curved surfaces and drilling into cross holes, stacked plates, castings, and other rough surfaces. To overcome these challenges, Kennametal Inc. (Pittsburgh, PA) developed an insert geometry (FEG) for the KenTIP FS modular drill series that streamlines these drilling applications and simplifies drilling of counterbores and pilot holes.
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. “It’s so versatile, you can use it for nearly all your drilling applications,” says Georg Roth, global product manager of hole making for modular drilling tools.
The FEG geometry features a 180-degree cutting edge and a conical center point, which acts as a pilot to provide exceptional hole position and straightness. Corner chamfers 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 0.236 inches to 1.024 inches (6.0 mm to 26.0 mm). Drilling depth up to 12xD is possible depending on the KenTIP FS modular drill body.
