Built from high-speed steel with a bright uncoated finish, it features a 135-degree split point and a web-thinned, tapered web construction that reduces walking on entry and lowers thrust requirements. The parabolic spiral flute promotes efficient chip evacuation, making it well suited for deeper holes. Overall length is 4.6063 inches (117 mm) with a flute length of 2.9528 inches (75 mm). The straight-cylindrical shank accepts standard drill chucks without adapters. This bit weighs approximately 0.083 pounds.\u003c\/p\u003e\n\u003cp\u003eThis jobber-length bit is a general-purpose drilling tool rated for use in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. It is a fit for machinists, maintenance technicians, pipefitters, plumbers, electricians, and HVAC professionals who need a reliable metric drill bit for production or field drilling. The QC21PM series is built to DIN 338 standards, making it a recognized specification in both shop and field environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8 mm (0.3150 inch) diameter, jobber length per DIN 338 specification\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces thrust and minimizes bit walking\u003c\/li\u003e\n  \u003cli\u003eParabolic spiral flute for efficient chip evacuation in deep drilling applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard keyed and keyless drill chucks\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating to delaminate; suitable for use with cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or stock bit compatible with any drill press, hand drill, or milling machine equipped with a standard chuck capable of accepting an 8 mm straight-cylindrical shank.

When drilling stainless steel, superalloys, or titanium, use an appropriate cutting fluid and reduce spindle speed to extend bit life. For production drilling or deep-hole work, clear chips frequently to prevent flute packing and overheating. Follow applicable shop safety standards and wear appropriate eye protection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8 mm (0.3150 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.6063 inches (117 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.9528 inches (75 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3150 inch (8 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.6535 inches (42 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.9528 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC21PM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.083 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: 5996929\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51707740848434,"sku":"5996929","price":24.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a85133a1139dc8a6ea2473e7ab0e3fa_f991c589-6c0d-4d3e-b579-92a67891f6cd.jpg?v=1788441916","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996929-jobber-drill-bit-8mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
