Kennametal 2425149 Screw Machine Drill Bit 9.70mm Carbide

Product Description

The KENNAMETAL 2425149 is a screw machine length drill bit engineered for high-performance drilling in demanding production environments. Built from solid carbide and coated with TiAlN, this bit delivers extended tool life and heat resistance when cutting cast iron and steel. It features a 140-degree point angle with web thinning for reduced thrust and cleaner entry, and runs in a right-hand, regular spiral flute configuration. The 9.70 mm diameter and compact overall length of 89.00 mm make it well suited for screw machine and short-hole drilling applications where rigidity and precision are critical. Licensed machinists and tooling technicians are the primary installers and operators.

This drill bit is designed for use in CNC machining centers, screw machines, and drill presses where close-tolerance hole making in cast iron and steel is required. The straight cylindrical shank with a 10.00 mm shank diameter seats securely in standard collet chucks and drill holders. A maximum drilling depth of 35.00 mm makes it appropriate for shallow to mid-depth production holes. It conforms to DIN 6537K geometry standards, making it a direct fit in shops that specify DIN tooling. The Series B966A and Dynapoint High Performance grade designation indicate this is a production-grade tool intended for high-cycle industrial use.

Key Features

• Solid carbide construction with TiAlN coating for extended tool life and thermal resistance in ferrous materials
• 140-degree point angle with web-thinned, parallel web configuration reduces entry thrust and improves centering
• Right-hand, regular spiral flute geometry promotes efficient chip evacuation
• Straight cylindrical shank at 10.00 mm diameter ensures secure seating in standard collet and drill chuck holders
• Conforms to DIN 6537K specification for consistent geometry and interchangeability in DIN-standard tooling setups
• Dynapoint High Performance grade KC7315 carbide substrate for wear resistance in cast iron and steel cutting

Compatibility

Designed for use in screw machines, CNC machining centers, and drill presses with standard collet chucks or drill holders accepting a 10.00 mm straight cylindrical shank. Primary workpiece materials are cast iron and steel. Conforms to DIN 6537K specification.

Installation Notes

Installation and operation should be performed by qualified machinists or tooling technicians familiar with carbide tooling requirements. Ensure the machine spindle and tool holder are fully powered down and locked out before inserting or removing the bit. Verify the collet or chuck bore matches the 10.00 mm shank diameter and that the tool is seated to the full shank length before tightening. Carbide tooling is brittle and should never be used in applications with interrupted cuts or excessive runout without confirming the holder and spindle are within acceptable tolerance.
