Kennametal 6370936 Replaceable Drill Tip 0.5 in KC7410

Product Description

The KENNAMETAL 6370936 is a replaceable carbide drill tip engineered for high-performance drilling in cast iron and similar K-class workpiece materials. Manufactured from solid carbide with a PVD-applied AlCr coating, it delivers thermal resistance and wear protection in demanding machining environments. The tip features a 140-degree point angle and helical flute geometry, producing accurate entry and clean chip evacuation. A built-in coolant-through design channels cutting fluid directly to the cutting edge, reducing heat and extending tool life. This tip is designed for use with compatible KTFST-series drill bodies and is installed by qualified machinists and tooling technicians in production or job-shop settings.

The 6370936 tip is suited for drilling applications including inclined-surface entry, cross-hole drilling, and stacked-plate drilling. Its 2-flute, 4-margin geometry stabilizes the drill path in interrupted cuts and multi-layer workstacks. The HPC insert geometry supports high cutting speeds typical of modern CNC machining centers running cast iron components. This tip fits insert seat size O on compatible KTFST drill bodies.

Key Features

• Solid carbide construction, material grade K15, for hardness and rigidity in cast iron drilling
• PVD AlCr coating provides thermal and oxidation resistance at elevated cutting speeds
• 140-degree point angle with HPC geometry for accurate, low-thrust entry
• Coolant-through design delivers fluid to the cutting zone for heat management and chip flushing
• 2-flute, 4-margin configuration for improved hole straightness and stability
• Rated for inclined-exit, cross-hole, and stacked-plate drilling scenarios

Compatibility

Designed for use with KTFST-series replaceable-tip drill bodies accepting insert seat size O. The ISO number for this tip is KTFST05000HPC. Verify seat size and series compatibility with the drill body before installation.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Ensure the drill body is fully removed from the spindle and all machine motion is locked out before replacing the tip. Use the correct clamping torque specified by the drill body manufacturer for seat size O inserts. Inspect the insert seat for debris or damage before seating the new tip, as contamination at the seat interface affects runout and tip retention.
