Kennametal 6370974 Replaceable Drill Tip 6mm KCMS15

Product Description

The KENNAMETAL 6370974 is a replaceable carbide drill tip designed for use with KTFST-series modular drilling systems. The tip features a 6.00 mm cutting diameter, a 140-degree included point angle, and a solid carbide construction in a fine-grain grade designated KCMS15. An AlTiN coating applied via PVD process improves wear resistance and thermal stability during high-speed cutting operations. The helical, two-flute geometry with a standard point and regular spiral provides consistent chip evacuation. This tip is intended for installation and replacement by machinists and tooling technicians working with modular drill bodies.

This replaceable tip is engineered primarily for drilling stainless steel and other M-category workpiece materials. The Insert Seat Size B and HPL insert geometry make it suited to applications involving inclined exits, stacked plates, and standard through-hole drilling. Coolant-through capability supports higher cutting speeds and extends tool life in demanding materials. The clamp-style insert holding method provides secure, repeatable seating in compatible KTFST modular drill bodies.

Key Features

• Solid carbide fine-grain construction in KCMS15 grade for toughness and edge retention
• AlTiN PVD coating for thermal and wear resistance in stainless steel applications
• 140-degree standard point angle with helical two-flute geometry for stable entry and exit
• Coolant-through design to manage heat and clear chips in deep or difficult holes
• Rated for inclined-exit and stacked-plate drilling applications
• Clamp-held replaceable tip reduces downtime versus regrinding solid drills

Compatibility

Designed for use with KTFST-series modular drill bodies accepting Insert Seat Size B. ISO Number KTFST06500HPLM identifies the tip geometry and seat interface within the KTFST system.

Installation Notes

Installation and replacement should be performed by a qualified machinist or tooling technician. Ensure the drill body and seat are clean and free of chips or debris before seating the tip. Power down and lock out the machine spindle before tip changes. Follow the drill body manufacturer torque and clamping specifications for the seat size B interface.
