Kennametal 5397482 KSEM0781HPG KCPM45 Carbide Tip Drill

Product Description

The KENNAMETAL 5397482 is the KSEM0781HPG KCPM45 carbide replaceable tip drill from the KSEM Plus series. It carries a cutting diameter of 0.7811 inches (25/32 inches, 19.84 mm) and features a solid carbide tip with a TiAlN PVD coating and HPG insert geometry. The 140-degree drill point angle and regular helical spiral deliver consistent chip evacuation in steel and stainless steel applications. Internal coolant-through capability, including MQL (Minimum Quantity Lubricant) compatibility, supports thermal management during extended drilling cycles. The drill is clamped into a compatible KSEM body and is installed by machinists and tooling technicians in production and job-shop environments.

This replaceable tip drill is designed for ferrous metal drilling operations including through-drilling, inclined exit drilling, and stacked-plate drilling. It carries ISO number KSEM0781HPG and is rated for primary workpiece materials coded P (Steel) and M (Stainless Steel) per ISO material classification. The two-flute, two-margin configuration with coolant-through channels makes it well suited for demanding drilling cycles where tool life and hole quality are priorities in both manual and CNC machining setups.

Key Features

• Solid carbide tip with KCPM45 fine grain grade for wear resistance in steel and stainless steel
• TiAlN PVD coating reduces heat buildup and extends tip life
• 140-degree drill point angle with HPG insert geometry for controlled entry and exit
• Internal coolant-through channels compatible with both flood coolant and MQL delivery
• Two-flute, two-margin helical design supports inclined exit and stacked-plate drilling
• Clamp-held insert seat size 2 for secure, repeatable tip indexing

Compatibility

The KSEM0781HPG tip is compatible with KSEM Plus series drill bodies that accept insert seat size 2. It is rated for ISO material groups P (Steel) and M (Stainless Steel). Specific compatible drill body part numbers were not provided in the product data; consult the KENNAMETAL KSEM Plus series tooling guide for matching body configurations.

Installation Notes

Installation is performed by a qualified machinist or tooling technician on a CNC machining center or drill press. Power down and lock out the spindle before replacing or indexing the tip. Use the correct KSEM torx or clamping key to seat the tip securely against the insert pocket; do not substitute non-manufacturer tooling for the clamping operation. Verify coolant-through passages are clear and aligned before resuming cutting operations.
