It carries a No. 73 wire gauge size with a decimal diameter of 0.0240 inches and features a 130-degree split point with web thinning for self-centering entry without a center punch. The spiral flute geometry and right-hand cutting direction are optimized for consistent chip evacuation in tough alloys. At 26.00 mm overall length, this is a compact, precision drill built for high-performance applications where standard HSS tooling falls short.\u003c\/p\u003e\u003cp\u003eThis drill is sized for precision work in titanium alloys and other high-strength materials classified under material grade M35 cobalt. It is well suited for aerospace, medical device, and general metalworking applications where tight tolerances and clean entry holes are required. With a maximum drilling depth of 7.09 mm and a 5xD flute-to-diameter ratio, it is intended for shallow to moderate-depth drilling operations. It conforms to DIN 338 standards, making it compatible with tooling setups that require metric specification compliance. Machinists and toolroom technicians working with small wire-size drills in production or maintenance settings will find this series appropriate for their requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM35 cobalt steel construction for heat resistance and wear life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e130-degree split point with web thinning for self-centering, reduced thrust force drilling\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids on titanium and stainless alloys\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for reliable chip clearance in short-flute applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eDIN 338 specification conformance for consistent dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 338-compliant jobber drill for use in standard drill chucks and collet systems accepting a 0.61 mm straight-cylindrical shank, suited for CNC machining centers, drill presses, and hand-held power tools configured for small wire-size tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or toolroom technician familiar with small-diameter drill bits. Ensure the spindle and workholding are fully secured before beginning any drilling operation, and confirm spindle runout is within acceptable limits to avoid breakage of this small-diameter tool. Apply an appropriate cutting fluid for the workpiece material, particularly when drilling titanium or stainless steel. Avoid excessive feed pressure, as small wire-size drills are susceptible to breakage under lateral loading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 73\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0240 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt M35\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\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: Spiral, Regular Helix\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: 26.00 mm (approximately 1.02 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.61 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 18.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 7.09 mm (0.2790 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.012 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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: Titanium Alloy\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: DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 605\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Weight\u003c\/strong\u003e: 0.002 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 9006050006100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51731661029682,"sku":"9006050006100","price":15.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3330135add6b7a0117d5d0f6a0eade56_47ceffee-75c7-4d27-aeb8-217e24fc3a94.jpg?v=1788733660","url":"https:\/\/voomisupply.com\/products\/guhring-9006050006100-cobalt-jobber-drill-no-73","provider":"Voomi Supply","version":"1.0","type":"link"}
