Built from high speed steel with a bright, uncoated finish, it measures 4.45 mm (0.1752 inches) in diameter with a 130-degree drill point angle and a parabolic flute geometry that promotes efficient chip evacuation. The overall length is 3-5\/32 inches (80.00 mm), and the straight-cylindrical shank seats cleanly in standard drill chucks. Right-hand cutting direction and web-thinned tip geometry reduce entry force and walking on the initial cut. This bit is suited for trade professionals, tool and die shops, and machining operations requiring consistent, repeatable results.\u003c\/p\u003e\u003cp\u003eThis drill bit is engineered primarily for use on aluminum and non-ferrous materials, as indicated by the primary workpiece material codes K, N, and P. It fits standard jobber length drilling applications in light manufacturing, maintenance, and precision machining environments. The parabolic flute design handles deeper cuts efficiently, with a maximum drilling depth of 1.5880 inches (40.33 mm). Conforming to DIN 338, this bit is appropriate for use in both manual and CNC drilling setups where consistent dimensional accuracy is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4.45 mm (0.1752 inch) diameter with a diameter tolerance of -0.018 to 0.000 mm for tight-tolerance drilling\u003c\/li\u003e\n\u003cli\u003e130-degree split point angle with web-thinned tip reduces thrust and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003eParabolic flute design with a 5xD flute-to-diameter ratio promotes chip clearing in deeper bores\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction rated as high performance grade for demanding production use\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 338 specification for consistent interchangeability and quality standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 338-compliant jobber length drill bit suited for aluminum, plastic, and light ferrous materials in standard drill chuck setups, per primary workpiece material codes K, N, and P as stated in the manufacturer specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or tool operators familiar with drill press, hand drill, or CNC spindle operation. Ensure the workpiece is securely clamped and the chuck or collet is properly tightened before operation. Power down and de-energize any machine before changing bits or adjusting tooling. Follow applicable shop safety standards and machine manufacturer guidelines when selecting feed rate and spindle speed for the target material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.45 mm (0.1752 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-5\/32 inches (80.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-27\/32 inches (47.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.5880 inches (40.33 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eShank Diameter\u003c\/strong\u003e: 0.1752 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 33.00 mm\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\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.018 to 0.000 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum (Codes K, N, P)\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: 549\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9005490044500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728669606194,"sku":"9005490044500","price":27.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0b621bb15d09e135921b2b9717e6fa2.jpg?v=1788694701","url":"https:\/\/voomisupply.com\/products\/guhring-9005490044500-jobber-drill-bit-4-45mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
