Kennametal 2425117 Screw Machine Drill Bit 3.60mm Carbide

Product Description

The KENNAMETAL 2425117 is a screw machine length drill bit designed for high-productivity drilling in ferrous materials. Built from solid carbide and coated with a multilayer TiAlN finish, it delivers heat resistance and extended tool life in demanding production environments. The bit measures 3.60 mm in diameter with a 140-degree split point and an overall length of 62.00 mm (2.44 inches). A web-thinned geometry reduces thrust force and improves chip evacuation. This bit is installed by machinists and tool-and-die professionals in CNC and manual drilling operations requiring tight tolerances and consistent hole quality.

This drill bit is suited for short-hole drilling in cast iron and steel workpieces, particularly in applications where a compact tool length reduces deflection and improves rigidity. The screw machine length profile makes it well matched to gang drilling, turret lathes, and CNC machining centers running moderate to high feed rates. Maximum drilling depth is rated at 14.00 mm. The straight-cylindrical shank at 6.00 mm diameter seats cleanly in standard drill chucks and collet systems. DIN 6537K specification compliance confirms dimensional conformance for tool management in production shops.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• Multilayer TiAlN coating improves thermal protection and extends cutting life
• 140-degree point angle with web thinning reduces entry thrust and walking
• Screw machine length (62.00 mm OAL) minimizes deflection in short-hole applications
• Regular spiral flute with parallel web configuration promotes consistent chip flow
• DIN 6537K compliant for standardized tool management and replacement

Compatibility

Designed as an OEM-style replacement or direct tooling selection for applications requiring a 3.60 mm solid carbide screw machine drill conforming to DIN 6537K, Series B966. Primary workpiece materials listed by the manufacturer are cast iron and steel.

Installation Notes

This bit is installed by qualified machinists in machine tool spindles using a collet, chuck, or tool holder rated for the 6.00 mm straight shank diameter. Confirm the tool holder runout is within acceptable limits before seating the bit, as solid carbide is brittle and sensitive to lateral loading. Power down and lock out the machine before changing tooling. Do not use in hand-held drilling operations; solid carbide bits require the rigidity of a machine tool spindle.
