Kennametal 6388564 Replaceable Tip Drill 11/16 in Carbide

Product Description

The KENNAMETAL 6388564 is a solid carbide replaceable tip drill designed for high-productivity hole-making in steel and cast iron workpieces. The tip carries an AlTiN coating applied via PVD process, which improves heat resistance and extends tool life in demanding cutting environments. It features a 180-degree drill point angle, two helical flutes, and a two-margin geometry for stable entry and exit. The manufacturer grade is KCP15A with a fine-grain carbide substrate, and the HPG insert geometry is engineered for consistent chip control. The drill body uses a clamp-style insert holding method with an insert seat size of V, and the tool is part of the KTFSS series.

This replaceable tip drill is suited for general drilling operations in steel and cast iron in both production and job-shop environments. It is specifically rated for inclined exit drilling and stacked-plate drilling applications, making it appropriate for structural fabrication, machined-component production, and similar metalworking contexts. The two-flute, two-margin, no-coolant-through configuration is noted in the application data. It is intended for use by machinists and CNC operators working with ferrous workpiece materials designated under ISO material codes P and K.

Key Features

• AlTiN coating via PVD process for elevated heat and wear resistance
• KCP15A fine-grain solid carbide grade for toughness in steel and cast iron
• HPG insert geometry with two helical flutes and two margins for stable chip control
• Rated for inclined exit and stacked-plate drilling applications
• Clamp-style insert holding with V-seat for secure tip retention
• 180-degree drill point angle for standard entry geometry

Compatibility

Designed as a replaceable tip for KTFSS series drill bodies accepting the V insert seat size. Compatible with ISO designation KTFSS06875HPG. Verify body series and insert seat size before ordering.

Installation Notes

Installation and tip replacement should be performed by a qualified machinist with the machine in a de-energized, locked-out state. Use the appropriate clamp key or torque tool specified for the KTFSS body series when seating the tip. Inspect the insert seat for chips or contamination before installing a new tip. Follow the toolholder manufacturer guidelines for proper clamping torque and runout verification before resuming cutting operations.
