Kennametal 6388552 Carbide Replaceable Tip Drill 17mm

Product Description

The KENNAMETAL 6388552 is a replaceable-tip carbide drill designed for precision metal-cutting operations in machining and manufacturing environments. Built to the KTFS series standard, it accepts a solid carbide tip with an HPG insert geometry and a V-series insert seat. The cutting diameter measures 17mm (0.6693 inches), and the drill point is ground to a 143-degree included angle for controlled entry and reduced thrust in a range of workpiece materials. The AlTiN coating is applied via a PVD process, providing heat resistance and extended tool life in ferrous and non-ferrous cutting applications. This tool is installed and serviced by machinists and CNC toolroom technicians.

The 6388552 is suited for use in machining centers, CNC drilling, and boring operations where a replaceable-tip platform is preferred over solid-body drills. The KTFS series platform allows tip replacement without removing the drill body from the spindle, reducing downtime in production environments. Manufacturer grade KCP15A indicates a PVD-coated carbide substrate optimized for general-purpose and interrupted-cut drilling. Coolant-through capability is not included in this configuration.

Key Features

• 17mm (0.6693 inch) cutting diameter in the KTFS replaceable-tip series
• Solid carbide tip with KCP15A manufacturer grade for general-purpose metal cutting
• AlTiN coating applied via PVD process for elevated heat and wear resistance
• 143-degree drill point angle with HPG insert geometry for controlled entry
• V-series insert seat for positive tip seating and repeatable runout
• No coolant-through channels — suited for dry or external coolant applications

Compatibility

Designed as a replacement tip for KTFS series drill bodies requiring a V insert seat size with HPG geometry. Compatible bodies must accept the V-seat KTFS tip configuration. Verify body series and seat size before ordering.

Installation Notes

Installation and tip changes should be performed by a qualified machinist following the machine tool builder guidelines for replaceable-tip drill systems. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before handling any cutting inserts or tips. Use the appropriate torx or clamping key specified for the KTFS body to seat the tip fully without over-torquing. Inspect the insert seat for chips or debris before each tip installation to maintain runout accuracy.
