Kennametal 6370385 Replaceable Drill Tip 0.75 in KC7410

Product Description

The KENNAMETAL 6370385 is a replaceable drill tip engineered for high-performance drilling in cast iron and similar K-class workpiece materials. Manufactured from solid carbide in grade KC7410 with an AlCr PVD coating, this tip delivers wear resistance and thermal stability at the cutting edge. It carries a 0.7500-inch cutting diameter, a 140-degree included point angle, and a two-flute helical geometry with four margins. The HPC insert geometry and coolant-through design make it suited for demanding material removal where chip control and edge temperature are critical concerns. Licensed KENNAMETAL series KTFST, insert seat size X.

This drill tip is intended for use in KTFST-series replaceable-tip drill bodies configured for 0.7500-inch diameter tips with seat size X. Typical applications include straight-hole drilling, inclined exit drilling, cross-hole drilling, and stacked-plate drilling in cast iron workpieces. The coolant-through capability supports both flood and high-pressure coolant delivery, which is particularly valuable in deep-hole and interrupted-cut scenarios common in machining shops and production environments. Installation is performed by machinists and tooling technicians.

Key Features

• Solid carbide construction in grade KC7410, material grade K15, for long edge life in cast iron
• AlCr PVD coating provides oxidation resistance and reduces built-up edge formation
• Coolant-through design supports high-pressure coolant delivery for chip evacuation and thermal control
• 140-degree point angle with HPC geometry reduces thrust and improves centering on entry
• Two-flute, four-margin helical configuration for hole geometry accuracy and surface finish
• Compatible with inclined exit, cross-hole, and stacked-plate drilling applications

Compatibility

Designed for use in KENNAMETAL KTFST-series replaceable-tip drill bodies requiring a 0.7500-inch diameter tip with insert seat size X and ISO number KTFST07500HPC.

Installation Notes

Replaceable drill tips of this type are installed and torqued by qualified machinists or tooling technicians using the appropriate KENNAMETAL torque wrench for the KTFST seat. Power down and lock out the machine spindle before tip removal or installation. Inspect the seat bore and clamping surfaces for chips or damage before seating the new tip. Do not use substitute seating tools, as improper clamping force will compromise runout and edge life.
