Built from M41 cobalt high-speed steel, this bit delivers heat resistance and edge retention beyond standard HSS tooling. The 135-degree split point reduces walking and cutting force at entry, making it a reliable choice for production drilling environments. At 2.25 inches overall length, the stub-length design maximizes rigidity and minimizes deflection. Machinists, tool-and-die trades, and maintenance technicians use this bit in drill presses, CNC turret lathes, and hand-held pneumatic or electric drills.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling hard ferrous metals, stainless steel, high-nickel alloys, titanium, and other materials that generate elevated cutting temperatures. The screw machine length format is standard in production shops and toolrooms where clearance is limited or a stiffer setup is required. The straight-cylindrical shank fits standard three-jaw chucks and collet systems without modification. The 2.5xD flute-to-diameter ratio provides adequate chip evacuation for through-holes in the intended material range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM41 cobalt HSS construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust load and eliminates center-punch requirements on most setups\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 2.25 inches OAL maximizes rigidity and reduces deflection\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration supports free cutting and efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes and 1.1875-inch flute length\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards; rated for heavy-duty production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a No. 12 wire size (0.1890 inch decimal) stub-length drill bit compatible with any standard three-jaw chuck or collet accepting a 0.1890-inch straight-cylindrical shank. Suitable for use in drill presses, CNC machines, turret lathes, and handheld power drills configured for production or maintenance drilling in hard materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and changed by machinists or maintenance technicians following standard lockout-tagout procedures before securing or removing tooling from any powered machine. Ensure the chuck or collet is rated for the shank diameter and that spindle speed is set to a value appropriate for the workpiece material and bit diameter per standard machining reference tables. Do not run cobalt bits without adequate cutting fluid or coolant when drilling hard ferrous alloys, as dry cutting accelerates edge wear. Inspect the cutting edge and web condition before each use; resharpening is recommended when thrust load increases noticeably during entry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1890 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt HSS (M41 Grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1890 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 2.5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: M41CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5996034\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51701893234994,"sku":"5996034","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa2be07eba6984ccd5f161f94448d961_3c9ffcad-971c-463f-a7a9-a2ffa8adfefb.jpg?v=1788406605","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996034-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
