Kennametal 3690720 Replaceable Drill Tip 1.0630 in KC7315

Product Description

The KENNAMETAL 3690720 is a replaceable drill tip designed for use with KSEM modular drill bodies. It features a 1.0630-inch (27.00 mm) cutting diameter and a 140-degree drill point angle optimized for penetration and chip control. The insert is manufactured from fine-grain solid carbide and carries a PVD-applied TiAlN coating for heat and wear resistance at elevated cutting speeds. Seat size 6 ensures positive location in compatible KSEM holders. Licensed machinists and toolroom technicians install and index these tips as part of modular drill assemblies in production and job-shop environments.

This drill tip is rated for use across a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material groups P, M, K, N, and S. The HPG insert geometry supports helical fluting and is suited to through-hole and blind-hole drilling operations on CNC machining centers and drill presses where modular tooling systems are preferred for rapid tip changes without removing the holder from the spindle.

Key Features

• 1.0630-inch (27.00 mm) cutting diameter in KSEM series seat size 6
• 140-degree point angle for reduced thrust and self-centering entry
• Fine-grain solid carbide substrate with PVD TiAlN coating for extended tool life
• HPG insert geometry with 2-flute regular helical configuration
• Rated for P, M, K, N, and S ISO workpiece material groups
• Clamp-held replaceable tip design enables fast indexing without full tool removal

Compatibility

Designed for use with KSEM modular drill bodies accepting seat size 6 inserts. ISO number KSEMP2700HPGM identifies the insert geometry and seating interface for cross-referencing compatible holders.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the spindle drive before seating or removing the tip. Use the manufacturer-specified torx or hex key to secure the clamp mechanism — do not overtighten by feel alone; follow the holder manufacturer torque procedure. Inspect the insert pocket and seating surfaces for chips or debris before each tip change to ensure proper seating and runout control.
