Kennametal 6388591 Replaceable Drill Tip 18mm KCP15A

Product Description

The KENNAMETAL 6388591 is a replaceable drill tip designed for indexable drilling systems that accept KTFSS-series toolholders. Manufactured from solid carbide with a fine grain material grade, this tip carries the KCP15A manufacturer grade and features a Physical Vapor Deposition (PVD)-applied AlTiN coating for extended tool life in demanding cut conditions. The drill tip measures 0.7283 inches (18.00 mm) in cutting diameter and presents a 180-degree included angle with a standard point type. It seats at insert seat size W and is held by a clamp-style insert holding method. Machinists and toolroom technicians install this tip as part of a modular drilling setup to reduce changeover time and lower per-hole tooling cost.

This drill tip is suited for drilling operations in steel and cast iron workpieces, covering ISO material codes P and K. It supports helical flute geometry with a regular spiral and a two-flute, two-margin design without through-coolant. Applicable operations include straight drilling, inclined exit drilling, and stacked-plate drilling. The KTFSS series designation identifies the compatible toolholder family for this tip.

Key Features

• Solid carbide construction with fine grain material grade for rigidity and edge retention
• AlTiN coating applied via PVD process for thermal resistance and wear protection
• 180-degree drill point angle with standard point geometry for accurate entry and exit
• HPG insert geometry supports stable cutting action in steel and cast iron
• Two-flute, two-margin configuration without through-coolant requirement
• Compatible with inclined exit and stacked-plate drilling applications

Compatibility

Designed for use with KTFSS-series indexable drill toolholders requiring insert seat size W. Compatible primary workpiece materials are steel (ISO code P) and cast iron (ISO code K).

Installation Notes

Installation of replaceable drill tips should be performed by a qualified machinist or toolroom technician with the machine powered down and locked out per applicable safety procedures. Ensure the insert seat and clamping surfaces are clean and free of chips before seating the tip. Torque the clamp fastener using the toolholder manufacturer's specified wrench - do not use impact tools on clamp screws. Verify tip seating and runout before resuming drilling operations.
