Kennametal 5626720 Replaceable Tip Carbide Drill 20.5mm

Product Description

The KENNAMETAL 5626720 is a carbide replaceable tip drill designed for high-productivity metal cutting operations. Carrying the ISO designation KSEM2050HPGM and manufactured to grade KCPM45 with a fine grain carbide substrate, this insert-style drill features a 20.5mm cutting diameter and a 140-degree included point angle. The tip is coated with TiAlN via a PVD process for improved heat and wear resistance. Coolant-through capability, including MQL (Minimum Quantity Lubrication) compatibility, allows effective chip evacuation and thermal management during deep-hole drilling. This part is installed by machinists and tooling technicians in production and job-shop environments.

The KENNAMETAL 5626720 is suited for drilling into steel and stainless steel workpiece materials, corresponding to ISO material groups P and M. The HPG insert geometry and regular spiral helical flutes support clean entry and exit conditions across a range of demanding applications. Specific application coverage includes standard through-hole drilling, inclined surface exit, and stacked plate configurations. The clamp-style insert holding method provides secure tip retention at elevated feed rates. This tool fits within the KSEM Plus series platform, where the replaceable carbide tip indexes into a compatible steel shank body.

Compatibility

Designed for use with KSEM Plus series replaceable tip drill bodies accepting insert seat size 3. Compatible with steel and stainless steel workpieces classified under ISO material codes P and M. Verify body series, seat size, and clamping configuration before ordering the replacement tip.

Installation Notes

Installation is performed by qualified tooling technicians or machinists. Ensure the machine spindle is fully stopped and the tool holder is secured before seating or removing the replaceable tip. Use the appropriate torx or clamp key as specified by the body manufacturer for the KSEM Plus seat interface. Confirm coolant passage alignment when reinstalling to maintain through-coolant flow to the cutting edge.
