Built from high speed steel with a coated finish, this bit features a 140-degree faceted point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The straight-cylindrical shank measures 3.00 millimeters in diameter, and the overall length is 41.00 millimeters (approximately 1.61 inches). The right-hand spiral flute geometry and 5xD flute-to-diameter ratio make this bit well suited for precision, close-tolerance drilling. Machinists, tool and die technicians, and CNC operators working in production environments are the primary installers.\u003c\/p\u003e\u003cp\u003eThis bit is intended for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpiece materials. The screw machine length format offers a shorter, more rigid profile compared to jobber-length bits, which improves stability and accuracy in drill press, turret lathe, and CNC machining center setups. The 2-flute spiral design supports efficient chip clearing in through-hole and blind-hole drilling operations. Coolant-through capability is not available on this model.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eScrew machine length format for increased rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003e140-degree faceted point angle for accurate self-centering and reduced walking\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration reduces drilling thrust\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral fluting for consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0 to -0.014 mm for close-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length drill bit suitable for standard straight-cylindrical shank drill chucks and collet holders in drill press, lathe, and CNC machining applications where a short, rigid bit profile is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with proper chuck seating and runout verification. Confirm the shank diameter matches the holding device capacity before securing the bit. Power down and de-energize the machine spindle before changing tooling.
