Kennametal 3690481 Carbide Replaceable Tip Drill 17mm KC7315

Product Description

The KENNAMETAL 3690481 is a solid carbide replaceable tip drill insert engineered for use in KSEM Plus modular drilling systems. Identified by ISO number KSEMP1700HPGM and manufactured in grade KC7315, this insert features a TiAlN coating applied via PVD process and an HPG insert geometry. It carries a 17mm cutting diameter, a 140-degree drill point angle, and a helical flute design with two flutes. The insert is held in place by a clamp mechanism and seats into an Insert Seat Size 1 holder. It is designed for trade machinists and toolroom professionals working on CNC drilling operations across a wide range of workpiece materials.

This replaceable tip is suited for drilling applications in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material grades P, M, K, N, and S. Its fine-grain carbide substrate and TiAlN coating make it appropriate for high-demand production drilling where tool life and hole quality are critical. The KSEM Plus modular system allows the tip to be swapped without removing the holder body, reducing changeover time in production environments. Typical applications include general-purpose drilling on machining centers and CNC lathes.

Key Features

• 17mm cutting diameter with a 140-degree standard drill point angle for accurate entry geometry
• Solid carbide fine-grain substrate in manufacturer grade KC7315 for wear resistance
• TiAlN coating via PVD process for thermal and oxidation resistance at elevated cutting speeds
• HPG insert geometry optimized for chip control across multiple workpiece material families
• Two helical flutes with regular spiral for consistent chip evacuation
• Clamp-style retention into Insert Seat Size 1 holder for repeatable seating and runout control

Compatibility

Designed for use with KSEM Plus series modular drill bodies accepting Insert Seat Size 1 replaceable tip holders. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium as stated in the product specifications.

Installation Notes

Installation and replacement of carbide drill inserts should be performed by qualified machinists following the tool manufacturer torque and seating procedures for the KSEM Plus holder body. Power down and lock out the machine spindle before removing or installing any replaceable tip. Inspect the insert seat and clamping surfaces for chips or contamination before seating the new insert, as debris can affect runout and lead to premature failure. Refer to applicable shop safety standards and the machine tool operator manual for proper handling of carbide tooling.
