Built from solid carbide and coated with TiAlN at the tip, it delivers extended tool life and heat resistance in hard and abrasive materials. The bit features a 140-degree point angle for self-centering entry and reduced thrust force, a tapered web configuration for chip evacuation, and a right-hand spiral flute. Overall length is 2.5984 inches with a flute length of 0.9449 inches, sized at wire gauge number 20 (0.1610 inch diameter). Qualified machinists and tool-and-die technicians install this bit in CNC machining centers and screw machines.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for high-production screw machine operations, CNC drilling, and precision hole-making in ferrous and non-ferrous metals where tight tolerances and consistent hole quality are required. The 6.00 mm straight cylindrical shank fits standard collets and drill chucks. The coolant-through capability supports high-speed drilling applications where internal coolant delivery reduces heat buildup and extends cutting life. It conforms to DIN 6537K specification and belongs to Kennametal Series B051A-CPG.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN tip coating for elevated-temperature performance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed drilling with internal coolant delivery\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537K specification for consistent dimensional compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers, screw machines, and drill presses equipped with standard collets or drill chucks accepting a 0.2362 inch (6.00 mm) straight cylindrical shank.
