Built from high-speed steel with a bright uncoated finish, the bit features a 135-degree split point that reduces walking on contact and lowers the thrust required to start a hole. The parabolic flute geometry improves chip evacuation during deeper passes, keeping the cutting edge clear and reducing heat buildup. At 3.5 mm (0.1378 inches) in diameter with a 2-3\/4 inch overall length, it fits standard drill chucks and is sized for precision work in metalworking, fabrication, and maintenance applications.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. The straight cylindrical shank allows seating in any standard keyed or keyless chuck. The web-thinned, tapered web design reduces cutting resistance in tougher alloys. It is a practical choice for machinists, maintenance technicians, pipefitters, and fabricators working in shop or field environments where a reliable general-duty HSS bit is needed. The QC21PM series is manufactured to DIN 338 standards, ensuring consistent dimensional accuracy across the production run.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3.5 mm (0.1378 inches) diameter with a straight cylindrical shank of matching diameter\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces wandering and lowers entry thrust on hard materials\u003c\/li\u003e\n  \u003cli\u003eParabolic spiral flutes promote efficient chip removal during deep drilling passes\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web lowers cutting resistance in stainless steel and superalloys\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction rated for drilling steel, cast iron, non-ferrous metals, and titanium-based alloys\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 specification for jobber-length drill geometry and tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style general-purpose jobber-length drill bit suitable for standard drill chucks accepting straight cylindrical shanks.

Always wear appropriate eye protection and secure the workpiece before drilling. Reduce feed pressure when breaking through the far side of a workpiece to prevent bit grab or workpiece movement. For extended use in hard materials, apply cutting fluid to the flutes to manage heat and extend edge life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.5 mm (0.1378 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches (70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.5354 inches (39 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.2205 inches (31 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.5 mm (0.1378 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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.5354 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC21PM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 5996908\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51694393458994,"sku":"5996908","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a85133a1139dc8a6ea2473e7ab0e3fa_c95589d6-aa4a-4799-80cd-ad806ab35c46.jpg?v=1788323986","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996908-jobber-drill-bit-3-5mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
