Kennametal 5397499 Carbide Replaceable Tip Drill 27mm Ksem

Product Description

The KENNAMETAL 5397499 is a solid carbide replaceable tip drill in the KSEM Plus series, manufactured to ISO number KSEM2700HPGM in grade KCPM45 fine-grain carbide. It carries a PVD-applied TiAlN coating and features a 140-degree drill point angle with an HPG insert geometry. The tip mounts via clamp into an insert seat size 6 and delivers through-coolant capability, including support for MQL (Minimum Quantity Lubricant) systems. Designed for production drilling environments, it is the right tool for machinists and tooling engineers who need a repeatable, cost-effective solution without scrapping the drill body on tip wear.

This replaceable tip drill is engineered for drilling operations in steel and stainless steel, corresponding to ISO material groups P and M. It handles demanding applications including inclined entry and exit surfaces, stacked plates, and standard through-coolant drilling cycles. The helical, regular-spiral flute design with 2 flutes and 2 margins promotes chip evacuation and hole quality in interrupted and difficult-entry cuts. It is suited to CNC machining centers in both job shop and high-volume production settings where tooling consistency and insert-change speed matter.

Key Features

• Solid carbide KCPM45 fine-grain tip for wear resistance in steel and stainless steel
• PVD TiAlN coating reduces heat buildup and extends tool life in ferrous materials
• 140-degree drill point angle with HPG geometry for accurate, centered entry
• Through-coolant channels with MQL compatibility for effective chip flushing
• Helical 2-flute, 2-margin design supports inclined-exit and stacked-plate drilling
• Replaceable tip design preserves the drill body, reducing per-hole tooling cost

Compatibility

Designed as an OEM-specification replaceable tip for KSEM Plus series drill bodies accepting insert seat size 6. Compatible primary workpiece materials are steel and stainless steel (ISO material groups P and M).

Installation Notes

Installation and tip changes should be performed by a qualified machinist or tooling technician with the machine in a full stop, lockout/tagout state. Clean the insert seat thoroughly before seating the tip to ensure proper clamp engagement and runout. Follow the drill body manufacturer torque procedure for the clamping screw — do not overtighten. Verify coolant port alignment before resuming cutting operations.
