Kennametal 3690715 Replaceable Drill Tip 22mm KC7315 Carbide

Product Description

The KENNAMETAL 3690715 is a replaceable drill tip designed for use with KSEM modular drilling systems. It features a 0.8661 inch (22.00 mm) cutting diameter and a 140-degree point angle suited for consistent entry and reduced thrust in a wide range of workpiece materials. The tip is manufactured from solid carbide with a fine grain structure and carries a TiAlN coating applied via PVD process, which supports heat resistance and extended cutting life in demanding applications. The HPG insert geometry is engineered to manage chip evacuation and cutting forces in interrupted and continuous cuts. Installation requires a clamp-style insert holding method consistent with the KSEM platform. This tip is handled and installed by machinists and tool crib technicians in production and job-shop environments.

This drill tip is intended for use in drilling operations across a broad material range including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material codes P, M, K, N, and S. It is suited to both horizontal and vertical machining center setups where modular drill bodies in the KSEM series are in use. The seat size 3 designation matches the corresponding KSEM drill body seat, making correct body-to-tip pairing a required step before installation. Typical applications include through-hole and blind-hole drilling in automotive, aerospace, and general metalworking production environments.

Key Features

• 22.00 mm (0.8661 inch) cutting diameter with 140-degree standard point angle
• Solid carbide construction with fine grain material grade for edge stability
• TiAlN coating via PVD process for heat resistance in steel, stainless steel, and superalloy cutting
• HPG insert geometry promotes controlled chip formation and reduced cutting forces
• Compatible with KSEM modular drill bodies via clamp-style insert seat size 3 interface
• Regular helical flute with 2-flute configuration for efficient chip evacuation

Compatibility

Designed for use with KSEM series modular drill bodies requiring an insert seat size 3. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium (ISO codes P, M, K, N, and S). The ISO number for this tip is KSEMP2200HPGM.

Installation Notes

This replaceable tip is installed and changed by machinists or tooling technicians; always power down and lock out the machine spindle before seating or removing the insert. Verify the drill body seat size matches the size 3 designation on this tip before clamping. Use the appropriate torque wrench and KSEM clamping hardware specified by the drill body manufacturer — do not over-torque the clamp screw. Inspect the seating surface of the drill body for debris or damage before each tip change to ensure accurate tip runout and safe operation.
