Built from cobalt tool steel, this bit features a 135-degree split point that reduces walking and enables self-centering without a center punch. The straight shank measures 0.2500 inches in diameter, with a flute length of 3-3\/4 inches and an overall length of 6-1\/8 inches. Right-hand spiral fluting with a 6xD flute-to-diameter ratio promotes efficient chip evacuation. This bit is suited for professional machinists, maintenance technicians, and fabricators working on production or repair tasks that require a longer reach than a jobber-length bit provides.\u003c\/p\u003e\u003cp\u003eThis taper length bit is intended for use in drill presses, CNC machining centers, and hand-held power drills where deeper hole penetration or longer reach is needed. The M51CO series designation indicates a heavy-duty cobalt construction with web thinning and a tapered web configuration, which reduces cutting force and improves performance in tough materials. It is equally effective in light metals and high-strength ferrous alloys, making it a versatile addition to a professional toolbox.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool material for heat resistance and extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point enables self-centering and reduces thrust force without a pilot hole\u003c\/li\u003e\n\u003cli\u003eTaper length body provides additional reach compared to standard jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with 6xD ratio supports efficient chip removal in deep holes\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web configuration reduces cutting resistance\u003c\/li\u003e\n\u003cli\u003eStraight shank compatible with standard drill chucks; no threading on shank\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling into a broad range of materials including alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, cermet, copper, graphite, hardened steel, high strength bronze, magnesium, magnesium alloy, malleable iron, nickel, nickel alloy, reinforced plastic materials, and stainless steel.

Always secure the workpiece and ensure the drill chuck is fully tightened before operation. Reduce spindle speed and apply appropriate cutting fluid when drilling hardened steel or stainless steel to prevent premature wear. Inspect the cutting edges before each use and do not use a bit with chipped or worn flutes, as this can cause workpiece damage or bit breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 1\/4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\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\u003eFlute Length\u003c\/strong\u003e: 3-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length x Diameter Ratio\u003c\/strong\u003e: 6xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreaded Shank\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Self-Centering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: M51CO\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\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: 5996574\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51714256830770,"sku":"5996574","price":36.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4384cf74ba866935d20ba7e6fe2e223a_ce061926-e11a-40f8-a18a-1a288688c515.jpg?v=1788498367","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996574-taper-length-cobalt-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
