Kennametal 6370361 Carbide Replaceable Tip Drill 17.3mm

Product Description

The KENNAMETAL 6370361 is a carbide replaceable tip drill in the KTFST series, designed for high-performance drilling in cast iron and similar K-class workpiece materials. The drill features a 17.3mm (0.6811 inch) cutting diameter, a 140-degree drill point angle, and a two-flute helical design with four margins and through-coolant capability. The cutting tip is manufactured from solid carbide in grade KC7410, coated with an AlCr finish applied via PVD process. This part is installed by machinists and CNC operators working in precision metal cutting environments where tool life and hole quality in difficult materials are critical.

The KTFST series replaceable tip drill is suited for drilling operations in cast iron (ISO material code K, material grade K15) across a range of machining applications. Supported operations include standard drilling, inclined exit drilling, cross-hole drilling, and stacked plate drilling. The clamp-style insert holding method and standard point geometry make it compatible with high-production and job-shop CNC drilling setups. Through-coolant delivery supports chip evacuation and thermal management during deep or interrupted cuts.

Compatibility

Designed for use in KTFST series replaceable tip drill bodies that accept Insert Seat Size V. Primary workpiece material is cast iron (ISO code K, material grade K15). Consult the tool body manufacturer specifications to confirm shank compatibility before installation.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine in a fully stopped and locked-out state. Ensure the replaceable tip is seated correctly in the drill body and the clamp is secured before operation. Through-coolant passages should be inspected and confirmed clear before use. Follow the tool manufacturer torque and assembly guidelines for the KTFST body when changing tips.
