Kennametal 5397491 Carbide Replaceable Tip Drill 25mm Ksem

Product Description

The KENNAMETAL 5397491 is a solid carbide replaceable tip drill in the KSEM Plus series, designed for high-productivity hole-making in steel and stainless steel applications. The tip carries manufacturer grade KCPM45 with a TiAlN PVD coating and an HPG insert geometry. It features a 25mm (63/64 inch) cutting diameter, a 140-degree drill point angle, and two helical flutes with two margins. Coolant-through capability, including MQL (Minimum Quantity Lubricant) support, allows effective chip evacuation and heat management at the cutting edge. Licensed machinists and CNC operators in production machining and job shop environments are the primary installers of this insert-style tooling.

This replaceable tip drill is suited for drilling operations in ISO material groups P (steel) and M (stainless steel). Typical applications include through-drilling, inclined-exit drilling, and stacked-plate drilling. The KSEM insert seat size 5 body accepts the KSEM2500HPGM tip, maintaining consistent tool geometry across tip changes without resetting offsets. The helical regular-spiral flute form promotes controlled chip flow in medium-to-long chipping materials common in steel and stainless steel machining.

Key Features

• Solid carbide fine-grain KCPM45 grade tip for wear resistance in steel and stainless steel
• TiAlN PVD coating reduces heat buildup and extends tool life at elevated cutting speeds
• 140-degree standard point angle suited for flat-bottom entry and exit conditions
• Coolant-through design supports both flood coolant and MQL delivery strategies
• HPG insert geometry with 2-flute, 2-margin configuration for stable, accurate hole geometry
• Replaceable tip system allows tip swap without removing the drill body from the spindle

Compatibility

Designed for use with KSEM Plus series drill bodies accepting insert seat size 5. Compatible with ISO workpiece material groups P (steel) and M (stainless steel). The ISO tip designation is KSEM2500HPGM.

Installation Notes

Installation and tip replacement should be performed by a qualified machinist or CNC tooling technician with the machine in a full stop, locked-out state. Use the appropriate KENNAMETAL clamping torx or hex key for the insert seat clamp — follow the toolholder documentation for the correct fastener and seating procedure. Verify tip seating and clamp engagement before spindle restart. Coolant-through connections should be confirmed clear and leak-free before resuming cutting operations.
