Machined from high-speed steel (HSS) with a bright, uncoated finish, it cuts at a 0.0960-inch diameter and features a 135-degree split-point tip for fast penetration and reduced walking on entry. The 2-flute regular spiral flute geometry evacuates chips efficiently during through-hole and blind-hole operations. With a 2.375-inch overall length and a 1.375-inch flute length, this bit is sized for use in standard drill presses, CNC drilling centers, and hand-held power drills. It is installed and used by machinists, maintenance technicians, and metal fabricators working on production or repair tasks.\u003c\/p\u003e\u003cp\u003eThis jobber drill is suited for drilling steel, aluminum, and other non-ferrous workpiece materials in light to medium production environments. The QC21P series is a general-purpose line built to ANSI standards, making it a dependable fit for machine shops, HVAC fabrication, plumbing rough-in work involving metal framing, and electrical trade applications requiring clean, accurate holes in sheet metal or structural steel. The straight cylindrical shank with a 0.2500-inch diameter fits standard three-jaw chucks and collet systems without modification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 41 wire size with a 0.0960-inch cutting diameter for precise small-hole work\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust and minimizes bit walking on entry\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles steel, aluminum, and non-ferrous alloys\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with web-thinned, tapered web geometry for improved chip clearance\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — ready to use as-is or accept aftermarket coatings\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards; rated for a maximum drilling depth of 1.375 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose OEM-style jobber drill for use in any standard drill press, hand-held power drill, or CNC spindle accepting a 0.2500-inch straight shank.

Secure the shank to the full recommended grip depth before operation, and confirm spindle speed is appropriate for the workpiece material and bit diameter per standard machining feeds-and-speeds references. Wear appropriate eye protection and secure the workpiece before drilling. Inspect the cutting edges for wear or chipping before each use; a dull bit increases thrust and can crack the web on small-diameter HSS tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 41\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0960 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.000 inches\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Aluminum, Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC21P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\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: 5997155\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693142016306,"sku":"5997155","price":67.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14c3de90969c6378087aaa7d157a7434_0ec73d56-9824-4a4b-a3fd-a3d397150728.jpg?v=1788307882","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997155-no-41-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
