Built from high-speed steel with an oxide coating, it carries a wire gauge size 4 designation, corresponding to a decimal diameter of 0.2090 inches. The 135-degree split point reduces walking at entry and lowers thrust force compared to a standard 118-degree tip. The web-thinned, parallel-web construction further reduces the force required to start and complete a hole. At 2.375 inches overall length, this stub-length bit is optimized for use in tight clearance applications and production setups where rigidity matters. Licensed machinists, tool-and-die workers, and maintenance technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eScrew machine length bits are a standard choice in CNC machining centers, drill presses, and turret lathes where reduced overhang improves concentricity and reduces deflection. The straight-cylindrical shank fits standard three-jaw drill chucks and collet-style toolholders without modification. The right-hand spiral flute with oxide finish suits general-purpose ferrous metal drilling where coolant-through tooling is not required. This bit is sold as a single unit and is intended for use by production machinists and maintenance technicians working in industrial, manufacturing, or fabrication environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces drill walk and lowers entry thrust force\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web construction for easier penetration in harder materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction withstands elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eOxide coating provides mild lubricity and corrosion resistance during storage and use\u003c\/li\u003e\n  \u003cli\u003eStub screw machine length improves rigidity and reduces deflection in close-clearance setups\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard screw machine length drill bit for use in drill presses, CNC machining centers, turret lathes, and hand-held drill equipment accepting a straight-cylindrical shank in the 0.2090-inch diameter class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tool safety. Secure the shank fully in the chuck or collet and verify runout before beginning a cut. Always power down and lock out the spindle before changing tooling.
