It is designed for drilling into hard and abrasive materials where standard high-speed steel bits wear prematurely. The 135-degree split point reduces walking and allows faster penetration without a center punch. At 1-13\/16 inches overall length with a 13\/16-inch flute, this stub-length geometry provides added rigidity and reduced deflection in short-hole drilling applications. The M41CO cobalt alloy construction delivers heat resistance in high-feed or interrupted-cut conditions. Machinists, tool and die workers, and maintenance technicians install and use this bit in drill presses, CNC machines, and hand drills.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production drilling in hard ferrous metals, stainless steel, titanium, and other difficult-to-machine materials. The screw machine length format makes it a preferred choice in turret lathes, screw machines, and bench drill press setups where a shorter, stiffer bit reduces chatter and improves hole accuracy. The straight-cylindrical shank fits standard three-jaw chucks and collet-style toolholders without modification. It is appropriate for both shop and field maintenance work where hole quality and bit longevity under heat matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 37 wire size — 0.1040 inches decimal diameter for precise undersized or tapping-prep holes\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning reduces thrust and eliminates center-punch requirement\u003c\/li\u003e\n\u003cli\u003eM41CO cobalt alloy construction resists heat buildup in hard and abrasive workpieces\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length at 1-13\/16 inches overall provides maximum rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute for standard clockwise drill operation\u003c\/li\u003e\n\u003cli\u003eTapered web configuration with 2.5xD flute-to-diameter ratio balances chip evacuation with core strength\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine drill bit for any standard three-jaw chuck or collet toolholder accepting a 0.1040-inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and used by machinists and maintenance technicians following standard metal-cutting practices. Secure the shank fully in the chuck or collet before operation and verify runout before drilling into workpieces. Always power down the machine and lock out energy sources before changing bits. Cutting fluid or coolant is recommended for hard ferrous and stainless steel applications to extend bit life, as this bit does not support through-coolant delivery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 37\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M41 Grade)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: M41CO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eTool Performance\u003c\/strong\u003e: High Performance, Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5996073\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51703953129778,"sku":"5996073","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa2be07eba6984ccd5f161f94448d961_fde850a4-1f53-4808-a872-8e46c03ec06f.jpg?v=1788419652","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996073-no-37-cobalt-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
