Kennametal 6388628 Replaceable Drill Tip 9.00mm KCP15A

Product Description

The KENNAMETAL 6388628 is a replaceable drill tip engineered for use with KENNAMETAL KTFS-series modular drilling systems. Manufactured from solid carbide and coated with AlTiN via a PVD process, this tip delivers hardness and thermal resistance suited to ferrous and stainless steel applications. The cutting diameter is 9.00 mm (0.3543 inches), the drill point angle is 143 degrees, and the insert seat size is H. The HPG insert geometry promotes stable chip formation and reduces thrust force during drilling. This tip is installed by machinists and toolroom professionals in CNC turning centers and machining centers where consistent hole quality and tool life are priorities.

The 6388628 is designed for use in the KENNAMETAL KTFS modular drill platform, seat size H. It fits applications requiring a 9.00 mm diameter through-hole or blind-hole in steel, cast iron, and similar materials where a 143-degree point angle provides a favorable entry geometry. The tip is replaceable without removing the entire drill body from the machine, reducing changeover time in production environments. This configuration suits high-volume metal removal operations in manufacturing, job shop, and aerospace component machining scenarios.

Key Features

• Solid carbide construction for hardness and wear resistance in metal cutting
• AlTiN coating applied via PVD process for elevated thermal resistance and extended tool life
• 143-degree drill point angle with HPG insert geometry for reduced thrust and stable entry
• 9.00 mm (0.3543 inch) cutting diameter, insert seat size H
• Replaceable tip design minimizes downtime during tooling changeover
• Compatible with KENNAMETAL KTFS-series modular drill bodies

Compatibility

Designed as an OEM-style replacement tip for KENNAMETAL KTFS-series modular drill bodies requiring an H-seat, 9.00 mm cutting diameter tip.

Installation Notes

Installation and removal of replaceable drill tips should be performed by a qualified machinist following the toolholder manufacturer's torque and seating procedures. Power down and lock out the spindle before changing any insert or tip. Inspect the seat bore for chips, contamination, or wear before seating the new tip. Do not use damaged or worn seat bores, as improper seating affects runout and hole accuracy.
