Kennametal 2250824 Drill Bit 5.20mm Solid Carbide Tialn

Product Description

The KENNAMETAL 2250824 is a screw machine length drill bit engineered for high-performance drilling in cast iron and steel. Built from solid carbide in the KC7315 material grade, it carries a TiAlN coating for heat resistance and extended tool life under demanding cutting conditions. The 140-degree point angle reduces thrust and improves self-centering on entry. At 66.00 mm overall length with a 28.00 mm flute length, this stub-length geometry provides rigidity and minimizes deflection. A web-thinned, parallel web configuration reduces cutting force at the tip. This bit is used by machinists and maintenance technicians on CNC machining centers, drill presses, and manual lathes where consistent hole quality is required.

The 2250824 is suited for production and repair environments where tight tolerances on ferrous materials are the standard. It targets cast iron and steel workpieces and fits applications where screw machine length rigidity is preferred over jobber-length flexibility. The straight cylindrical shank measures 6.00 mm in diameter and 36.00 mm in length, making it compatible with standard collet chucks and drill chucks sized for that shank diameter. Maximum recommended drilling depth is 20.00 mm. The 5.20 mm cutting diameter falls within the B966A series size range of 5.00 mm to 6.50 mm and meets DIN 6537K specification.

Key Features

• Solid carbide KC7315 grade construction for hardness and wear resistance in ferrous materials
• TiAlN coating extends tool life under high-temperature cutting conditions
• 140-degree point angle with web-thinned tip reduces entry thrust and improves hole location accuracy
• Screw machine (stub) length body at 66.00 mm OAL provides superior rigidity over jobber-length alternatives
• Right-hand cutting, regular spiral flute, rated for cast iron and steel
• Meets DIN 6537K specification; Dynapoint High Performance grade designation

Compatibility

Designed for use in standard collet chucks and drill chucks accepting a 6.00 mm straight cylindrical shank. Intended primary workpiece materials are cast iron and steel per KENNAMETAL B966A series specifications.

Installation Notes

Installation and use of carbide drill bits should be performed by qualified machinists or tooling technicians. Secure the straight shank fully in the chuck or collet and verify runout before cutting. Power down the machine completely before changing tooling. Avoid side loading or using this bit as a boring tool, as solid carbide is brittle and susceptible to breakage under lateral force.
