Kennametal 2658397 Taper Length Drill Bit 17/64 in

Product Description

The KENNAMETAL 2658397 is a taper length drill bit built for high-performance drilling in demanding trade and industrial applications. Manufactured from solid carbide and coated with TiAlN for extended tool life, this bit delivers consistent cutting performance in hard and abrasive materials. It measures 0.2656 inches (17/64 inch) in diameter with an overall length of 4.1339 inches and a flute length of 2.6378 inches. The 132-degree point angle supports accurate entry and reduced thrust. Right-hand spiral flutes and a web-thinned, tapered web design improve chip evacuation and reduce walking at the drill point. Licensed machinists, toolroom technicians, and maintenance professionals install this bit in CNC machining centers and drill presses alike.

This bit is rated for use in cast iron and steel. The straight cylindrical shank measures 0.3150 inches in diameter and 1.4173 inches in length, fitting standard drill chucks and collet holders in both benchtop and machine-mounted applications. Coolant-through capability supports internal coolant delivery when used in compatible spindles, making it well suited for deep-hole work and high-feed-rate operations in ferrous metals. Maximum drilling depth is rated at 2.2440 inches. The bit conforms to DIN 6537K specification, ensuring consistent dimensional control across the series.

Key Features

• Solid carbide construction with TiAlN coating for heat and wear resistance in ferrous materials
• 132-degree standard point angle for reduced thrust and accurate positioning
• Coolant-through design supports internal coolant delivery in compatible machine spindles
• Web-thinned, tapered web configuration improves chip flow and reduces cutting force
• Right-hand spiral flutes with regular spiral type for consistent chip evacuation
• Conforms to DIN 6537K specification for dimensional consistency

Compatibility

Rated for drilling cast iron and steel. Designed for use in CNC machining centers and drill presses with standard straight-shank collet holders or drill chucks accepting a 0.3150-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with carbide tooling. Secure the straight shank fully in the collet or chuck before operation and verify runout before cutting. Carbide tooling is brittle — avoid side loads and interrupted cuts that exceed the tool rating. When using coolant-through capability, confirm that the spindle and toolholder are compatible with internal coolant delivery before engaging the coolant supply.
