Built from M-2 High Speed Steel with a bright\/uncoated finish, it measures 0.0310 inches (1\/32 inch, Wire Size 68) in diameter and features a standard 118-degree split point with web thinning for improved centering and reduced thrust. The overall length is 46.00 mm (approximately 1.81 inches), with a flute length of 25.00 mm (approximately 0.98 inches) and a cylindrical shank. Manufactured to DIN 340 specification, this bit suits precision small-hole work where consistent diameter tolerance and straight entry are required.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for light-duty production and maintenance drilling applications where a small-diameter, taper-length configuration is needed. The 10xD flute-to-diameter ratio provides added reach compared to a jobber-length bit without sacrificing rigidity. Typical applications include sheet metal perforation, printed circuit board work, precision part fabrication, and similar tasks performed by machinists, toolmakers, and maintenance technicians. The right-hand spiral flute clears chips efficiently in through-hole and blind-hole operations at standard drill press or CNC spindle speeds for this diameter range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM-2 High Speed Steel construction for durability across general-purpose materials\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web thinning for improved start accuracy and lower thrust\u003c\/li\u003e\n  \u003cli\u003eDIN 340 taper length configuration — longer flute reach than jobber-length at 10xD ratio\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use with cutting fluid in most common materials\u003c\/li\u003e\n  \u003cli\u003eCylindrical shank fits standard drill chucks without adapter; no threaded shank\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.000 to -0.012 mm supports close-tolerance hole requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production-use taper length drill bit conforming to DIN 340 Series 217 for 0.0310-inch (1\/32 inch) diameter applications in standard drill chucks accepting cylindrical shanks.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with small-diameter drill bit handling. Secure the cylindrical shank firmly in a drill chuck rated for the spindle speed appropriate to this diameter and workpiece material before operation. At very small diameters, bit breakage risk increases significantly with side loading or misaligned entry — use a center punch or pilot point to establish hole location before drilling. Apply cutting fluid when drilling ferrous metals to extend tool life and maintain tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0310 inches (1\/32 inch, Wire Size 68)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 46.00 mm (approximately 1.81 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 25.00 mm (approximately 0.98 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 21.00 mm (approximately 0.83 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0313 inches (0.79 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.9380 inches (23.82 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 10xD\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: Cylindrical, Non-Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: M-2 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.012 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 217\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 340\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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9002170007900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51747789504818,"sku":"9002170007900","price":132.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3d6d18361187c69069caba32e781eab6_2866076c-81bb-4b55-9500-90493410d17b.jpg?v=1788885509","url":"https:\/\/voomisupply.com\/products\/guhring-9002170007900-taper-length-drill-bit-0-0310-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
