Built to DIN 1897 standards, this Series 653 bit measures 6.45 mm (0.2539 inches) in diameter with a total overall length of 70 mm (2.76 inches) and a flute length of 31 mm (1.22 inches). The 118-degree cone relief point and web-thinned tip reduce entry force and improve chip evacuation. The straight-cylindrical shank seats reliably in standard drill chucks and collet holders used in CNC machining centers, drill presses, and manual machines.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production and maintenance applications in shops working with steel and cast iron. Its stub-length body provides added rigidity compared to jobber-length bits, making it a preferred choice for screw machine work, tight-clearance drilling, and applications where deflection control matters. The 2-flute regular spiral geometry and 3xD flute-to-diameter ratio support efficient chip removal at standard cutting parameters. The h8 diameter tolerance ensures consistent fit in tight-tolerance setups. It is sold individually and is appropriate for machinists, toolroom technicians, and maintenance professionals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDIN 1897 stub-length geometry for enhanced rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003e118-degree cone relief point with web thinning for reduced entry force\u003c\/li\u003e\n\u003cli\u003eHigh speed steel M2 grade construction for durability in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank with h8 diameter tolerance for consistent chuck seating\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral design supports efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement — suitable for dry or flood-cooled operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or production drill for use in standard drill chucks and collet systems accepting a 6.45 mm straight-cylindrical shank.

Secure the shank fully in a properly sized drill chuck or collet before operation and verify runout is within acceptable tolerance for the application. Ensure the machine spindle is fully stopped before changing tooling. Follow applicable shop safety protocols and OSHA machine guarding requirements when operating drill presses or CNC equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2539 inches (6.45 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.76 inches (70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.22 inches (31 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.84 inches (21.33 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.45 mm straight-cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cone Relief\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel (M2)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Coated\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\u003eDiameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 653\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 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: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9006530064500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727153135922,"sku":"9006530064500","price":33.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8271eded756f86fcf13fa10ea67b3620.jpg?v=1788674075","url":"https:\/\/voomisupply.com\/products\/guhring-9006530064500-screw-machine-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
