Kennametal 1982397 Screw Machine Drill Bit 6.20 Mm

Product Description

The KENNAMETAL 1982397 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding production environments. Built to DIN 6537K standards and finished with a TiAlN coating, this bit delivers extended tool life in abrasive and hard materials. It features a 140-degree split point, web-thinned geometry for reduced thrust and improved chip evacuation, and a straight cylindrical shank measuring 8.00 mm in diameter. At 79.00 mm overall length with a 34.00 mm flute length, it fits standard screw machine and CNC drilling setups. Material grade KC7315 with the Dynapoint High Performance designation makes this a production-grade tool for shops running high-cycle operations.

This drill bit is suited for drilling cast iron and steel in residential, commercial, and industrial machining applications. The short overall length and rigid solid carbide construction make it well-matched for CNC machining centers, turret lathes, and screw machines where runout control and repeatable hole tolerances are critical. The 140-degree point geometry is particularly effective when entering hardened or work-hardened steel surfaces. Two regular spiral flutes provide consistent chip clearance through the 24.00 mm maximum drilling depth.

Compatibility

Designed for use in cast iron and steel workpieces. Compatible with standard straight-shank drill chucks and collets accepting an 8.00 mm shank diameter. Series B966A.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out. Verify chuck or collet bore matches the 8.00 mm shank diameter before mounting. Confirm recommended cutting speeds and feed rates for the workpiece material per the machine tool manufacturer and tooling guidelines before starting a cut. Do not use this bit in hand-held drilling applications.
