Kennametal 6388739 Replaceable Tip Drill 24mm Ktfs KCP15A

Product Description

The KENNAMETAL 6388739 is a replaceable tip drill designed for high-performance metal cutting applications. It carries the KTFSS24000HPGM tip designation with a KCP15A solid carbide grade and an AlTiN coating applied via PVD process. The cutting diameter is 24mm (0.9449 inches) with a 143-degree drill point angle and HPG insert geometry. The AlTiN finish provides heat resistance and wear protection in demanding cutting conditions. This drill body is part of the KTFS series and accepts a ZC insert seat size. It is installed and serviced by machining professionals in production and toolroom environments.

This replaceable tip drill is suited for machining operations requiring precise hole geometry in ferrous and non-ferrous materials. The KTFS series platform allows the tip to be swapped without replacing the entire drill body, reducing tooling cost per hole. The HPG geometry supports chip evacuation in through-hole and blind-hole applications. No internal coolant delivery is included, making this configuration appropriate for setups using external flood coolant or mist systems.

Installation Notes

Replaceable tip drills of this type are installed and changed by machinists or tooling technicians. Power down and lock out the spindle before tip removal or installation. Use the appropriate torque wrench and Kennametal-specified seating procedure for the KTFS body to ensure proper tip seating and runout. Do not force the tip into the seat; inspect the seat for chips or damage before each tip change.
