Built from high-speed steel (HSS) with a bright uncoated finish, this bit features a 135-degree split point and a parabolic spiral flute pattern with web thinning for reduced thrust and cleaner entry. The straight cylindrical shank measures 5\/64 inch (0.0785 inch decimal) in diameter with an overall length of 2 inches and a flute length of 1 inch. It cuts right-hand and is suited for use in standard drill chucks. HVAC technicians, plumbers, electricians, and general trade mechanics rely on this size for sheet metal, bracket, and conduit work requiring a small-diameter pilot or through-hole.\u003c\/p\u003e\u003cp\u003eThis bit is rated for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. The QC21P series targets heavy-duty general-purpose applications where a reliable HSS bit at a small diameter is needed. A 13xD flute-to-diameter ratio provides adequate chip evacuation for the 1-inch maximum drilling depth. No coolant-through feature is present, so conventional cutting fluid application at the workpiece is standard practice for harder substrates.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 47 wire gauge size, 5\/64 inch diameter (0.0785 inch decimal) for precise small-hole work\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces walking and lowers entry thrust on hard materials\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with bright uncoated finish for general-purpose durability\u003c\/li\u003e\n\u003cli\u003eParabolic spiral flute with web thinning promotes chip clearance and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI standards; QC21P series heavy-duty grade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with any standard drill chuck accepting a 5\/64 inch straight cylindrical shank.

Secure the shank fully in the chuck and verify runout before drilling. Power down and disconnect the drill or machine before changing bits. Apply cutting fluid when drilling stainless steel, cast iron, or superalloys to extend tool life and reduce heat.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 47\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 5\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.0785 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: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/64 inch (0.0785 inch decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC21P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 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: 5997002\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51689592226098,"sku":"5997002","price":66.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14c3de90969c6378087aaa7d157a7434.jpg?v=1788261529","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997002-no-47-5-64-in-hss-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
