Kennametal 6370931 Replaceable Drill Tip 0.7188 in Grade KCMS15

Product Description

The KENNAMETAL 6370931 is a replaceable drill tip designed for use with KTFST-series indexable drill bodies. It features a 0.7188 inch cutting diameter, a 140-degree point angle, and a helical flute design with two flutes and two margins. The tip is manufactured from fine-grain solid carbide and carries a KCMS15 grade designation with an AlTiN coating applied via PVD process. Coolant-through capability is built in, supporting high-pressure internal coolant delivery. This tip is installed by machinists and toolroom technicians working in production or job-shop environments.

This replaceable tip is suited for drilling operations in stainless steel and other ISO M-group workpiece materials. The HPL insert geometry and 140-degree point angle support entry on inclined surfaces, stacked plate drilling, and inclined exit conditions. The seat size is W, matching the corresponding KTFST drill body seat. Typical applications include drilling in aerospace, medical, and industrial manufacturing where stainless steel is the primary workpiece material.

Compatibility

Designed for use with KTFST-series indexable drill bodies accepting seat size W inserts. The ISO designation for this tip is KTFST07188HPL. Verify seat size and series compatibility with the drill body before installation.

Installation Notes

This replaceable drill tip is installed by machinists using the clamp holding method specified for the KTFST drill body. Power down and de-energize the machine tool before changing the insert. Use the correct torque wrench and clamping hardware specified by the drill body manufacturer - do not over-torque the clamp screw. Ensure coolant ports are clear and aligned before resuming operation.
