Built to ANSI standards under the M41CO series, it features a 135-degree split point that reduces walking and minimizes the need for a center punch. The right-hand spiral flute geometry clears chips efficiently during operation. At 2-3\/8 inches overall length with a 1-1\/4 inch flute length, this stub-length bit provides increased rigidity over jobber-length alternatives, making it well suited to production drilling environments where chatter and deflection are concerns.\u003c\/p\u003e\u003cp\u003eThis bit is intended for use on hard and difficult-to-machine materials including stainless steel, high-nickel alloys, and hardened steel. The screw machine length format makes it a standard choice for turret lathes, screw machines, and CNC machining centers where a shorter, stiffer tool is required. Machinists, toolroom technicians, and production drill press operators working in metal fabrication and manufacturing shops will find this bit appropriate for both intermittent and production-rate drilling applications. Coolant-through capability is not available on this bit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt M41 high-speed steel construction for drilling hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning reduces thrust force and prevents bit walking\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length increases rigidity and reduces deflection in deep setups\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without special toolholding\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards for dimensional accuracy and tool geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use cobalt drill bit for applications requiring ANSI-standard screw machine length tooling in the 0.2000 to 0.2500 inch decimal inch drill size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or toolroom personnel familiar with metal cutting operations. Secure the straight-cylindrical shank firmly in a properly sized chuck or collet before operation, and verify that the machine spindle is completely stopped before changing tooling. Select feeds and speeds appropriate for the workpiece material and machine type; cobalt bits tolerate higher heat than standard HSS but still require proper cutting fluid application when drilling hard alloys. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2055 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: #5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M41 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: M41CO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\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\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.2000 to 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 pounds\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: 5996122\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51723883675954,"sku":"5996122","price":16.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa2be07eba6984ccd5f161f94448d961_c7b758f0-8ffa-46d3-bd65-4244890f34b4.jpg?v=1788609308","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996122-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
