Kennametal 6370992 Carbide Replaceable Tip Drill 8mm KCMS15

Product Description

The KENNAMETAL 6370992 is a carbide replaceable tip drill in the KTFS series, identified by insert ISO number KTFST08000HPLM and manufacturer grade KCMS15. The drill tip is manufactured from fine-grain solid carbide and coated with AlTiN via a PVD process, providing heat and wear resistance during demanding hole-making operations. It features a 140-degree drill point angle, a standard point type, and a regular helical flute geometry. The insert seat size is F, and the tip is retained by a clamp-style holding method. This tool is engineered for machinists and CNC operators running drilling operations in difficult-to-machine materials.

This replaceable tip drill is designed primarily for stainless steel workpiece materials (ISO material code M). The HPL insert geometry and through-coolant capability make it well suited for applications including standard drilling, inclined exit drilling, stacked plate drilling, and two-flute two-margin coolant-fed operations. It is intended for use in a compatible KTFS series drill body shank and delivers an 8mm cutting diameter in these applications.

Key Features

• Fine-grain solid carbide tip with AlTiN PVD coating for wear resistance in stainless steel
• 140-degree drill point angle with standard point type for accurate hole entry
• Through-coolant design supports chip evacuation and tool life in deep or difficult cuts
• HPL insert geometry with two flutes and two margins for stable cutting action
• Replaceable tip design reduces tooling cost compared to full solid carbide drills
• Supports inclined exit and stacked plate drilling applications

Compatibility

Designed for use with KTFS series replaceable tip drill body shanks that accept an F insert seat size. The ISO insert number KTFST08000HPLM identifies the correct body and seat pairing. Verify body shank compatibility with the KTFS series before ordering.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or tooling technician with the machine in a safe, powered-down state. Use the appropriate torque wrench or clamp key as specified for the KTFS series tool body - do not overtighten or cross-thread the clamp. Ensure coolant ports are clear before resuming operation. Follow the machine tool manufacturer and cutting tool guidelines for speed, feed, and coolant pressure when running through-coolant tooling.
