Kennametal 3690479 Carbide Tip Drill Insert 15mm Ksem

Product Description

The KENNAMETAL 3690479 is a solid carbide replaceable tip drill insert designed for the KSEM Plus modular drilling system. Identified by ISO number KSEMP1500HPGM, this tip carries the KC7315 manufacturer grade with a fine grain carbide substrate and a PVD-applied TiAlN coating. The cutting diameter is 15mm (0.5906 inches) with a 140-degree included drill point angle and a standard point type. The HPG insert geometry and helical flute configuration are engineered for controlled chip formation during through-hole and blind-hole drilling operations. Licensed HVAC, plumbing, and metalworking tradespeople familiar with indexable tooling will recognize this as a drop-in tip replacement rather than a full drill body.

This replaceable tip is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, corresponding to ISO workpiece material codes P, M, K, N, and S. It installs into compatible KSEM Plus drill bodies via a clamp-style insert holding method. The tip has a flute length of 7mm and an overall projection of 0.2953 inches. This configuration is typical in production machining environments, job shops, and maintenance applications where quick tip replacement reduces downtime compared to regrinding solid drills. Coolant-through capability is not included in this insert.

Key Features

• Solid carbide fine grain substrate with KC7315 grade for wear resistance in multi-material applications
• PVD TiAlN coating improves heat resistance and extends tool life in ferrous and superalloy materials
• 140-degree included drill point angle with HPG geometry for efficient chip evacuation
• Helical flute with regular spiral promotes consistent chip flow in 2-flute configuration
• Clamp-style insert holding method for repeatable tip indexing without full drill replacement
• Covers ISO material codes P, M, K, N, and S — broad workpiece material range in a single insert grade

Compatibility

Designed as a replaceable tip for the KSEM Plus modular drill body system, insert seat size A. Compatible with KSEM Plus drill bodies accepting the KSEMP 15mm HPG tip style.

Installation Notes

Installation is performed by a machinist or toolroom technician using the appropriate torque wrench or insert key specified for the KSEM Plus body. De-energize the machine spindle and verify zero-energy state before replacing the tip. Inspect the insert seat on the drill body for chips, debris, or wear before seating the new tip; a contaminated or damaged seat will affect runout and hole quality. Follow the drill body manufacturer torque specifications for the clamping screw — do not over-torque or substitute fasteners.
