Built from high-speed steel (HSS) with a bright, uncoated finish, it features a standard 118-degree point angle suited for a wide range of common drilling applications. The wire gauge Size 1 corresponds to a decimal diameter of 0.228 inches. With an overall length of 2.4375 inches and a flute length of 1.3125 inches, this stub-length bit provides increased rigidity compared to jobber-length drills, reducing deflection in short-hole and production drilling operations. It is installed by machinists, maintenance technicians, and tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThis bit is used in screw machine shops, production environments, and general maintenance applications where stub-length rigidity is preferred over standard jobber bits. Its right-hand cutting direction and regular spiral flute geometry make it a dependable choice for through-hole and blind-hole drilling in a manual or machine-operated drill press, turret lathe, or CNC screw machine setup. The 2-flute configuration handles chip evacuation efficiently in most common workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHSS construction provides durability and heat resistance for general-purpose drilling\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle suitable for a broad range of materials\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length increases rigidity and reduces bit deflection\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup to affect dimensional tolerance\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting with regular spiral flutes for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eStraight shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose screw machine length drill bit compatible with standard drill chucks and collet systems accepting a straight shank in the 0.200 to 0.250 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by machinists and maintenance technicians in drill presses, lathes, or CNC equipment. Secure the straight shank firmly in the chuck or collet before operation and verify runout before drilling. Power down or de-energize all equipment before changing tooling.
