Kennametal 3381124 Carbide Replaceable Tip Drill Ksem

Product Description

The KENNAMETAL 3381124 is a solid carbide replaceable tip drill in the KSEM series, designed for precision hole-making in a wide range of workpiece materials. It carries the KSEM0634HPL insert geometry with an HPL tip and a 140-degree drill point angle. The cutting diameter is 0.6335 inches (16.09mm), with a flute length of 8.00mm. The AlTiN coating is applied via a PVD process, providing thermal resistance and extended tool life in demanding cutting applications. This drill is intended for installation and use by machinists and tooling professionals in production and job-shop environments.

The KENNAMETAL 3381124 is suited for drilling operations in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material groups P, M, K, N, and S. It supports specific drilling applications including inclined exit surfaces and stacked plates, making it a versatile choice for challenging workpiece geometries. The helical flute design with a regular spiral promotes chip evacuation in through-hole and blind-hole operations. This is a single-tip replaceable style, with the tip secured via a clamp-style insert holding method.

Installation Notes

Replaceable tip drills of this type are installed by tooling professionals on CNC machining centers or manual drill presses following the machine tool manufacturer lockout and power-down procedures. Use the correct torque tool as specified by the drill body manufacturer when seating the tip to ensure proper clamp engagement. Inspect the insert seat and clamping surfaces for chips or contamination before each tip change. Do not exceed the cutting parameters published in the KENNAMETAL KSEM application guide for the specific workpiece material being drilled.
