Kennametal 6371044 Replaceable Drill Tip 10mm 140 Deg KCMS15

Product Description

The KENNAMETAL 6371044 is a replaceable drill tip designed for use with KTFST-series modular drilling systems. It carries ISO designation KTFST09900HPLM and is manufactured from solid carbide with a fine grain material grade. The tip measures 0.3898 inches (9.90 mm) in cutting diameter and features a 140-degree drill point angle optimized for clean entry and exit in demanding materials. An AlTiN coating applied via PVD process provides heat resistance and extended tool life. Coolant-through capability delivers cutting fluid directly to the cutting edge. This tip is installed by machinists and tool-crib technicians in CNC drilling applications.

This replaceable tip is suited for drilling operations in stainless steel (ISO material code M) and similarly difficult-to-machine alloys. Designed around a helical, 2-flute, 2-margin geometry with a regular spiral and standard point type, it performs well in through-hole drilling, inclined-exit drilling, and stacked-plate drilling scenarios. Insert seat size is I, and the tip is secured using a clamp-style insert holding method compatible with KTFST-series tool bodies.

Key Features

• Solid carbide construction with fine grain material grade for rigidity and wear resistance
• AlTiN coating via PVD process for elevated-temperature performance in stainless steel
• Coolant-through design channels fluid directly to the cutting zone
• 140-degree point angle reduces thrust force and improves chip formation
• 2-flute, 2-margin helical geometry supports inclined-exit and stacked-plate drilling
• Clamp-style retention in KTFST-series modular tool bodies for repeatable indexing

Compatibility

Designed for use with KTFST-series modular drill bodies accepting insert seat size I. ISO designation KTFST09900HPLM identifies the compatible seat geometry. Refer to the KTFST system tooling catalog to confirm body compatibility before installation.

Installation Notes

Replaceable drill tips of this type are installed and removed by qualified machinists or toolroom personnel following the tool body manufacturer's torquing and seating procedures. Ensure the machine spindle is powered down and locked out before changing the tip. Inspect the insert seat for chips or debris before seating the new tip, as contamination will affect runout and tool life. Follow the tool body manufacturer's clamping specifications to achieve correct seating.
