Built to DIN 1897 standards from M2 high-speed steel, it features a 118-degree standard point angle with web thinning on a tapered web for easier entry and reduced thrust. The cutting diameter is letter size F, equal to 0.2571 inches, with a straight-cylindrical shank of 6.53 mm (0.2571 inches) diameter. Overall length is 70 mm (2.756 inches). The shortened flute length and stub body make this bit well suited for rigid setups where a standard jobber-length drill would flex or chatter.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in screw machine operations, CNC drilling centers, drill presses, and manual turret lathes where compact tooling is required. Primary workpiece materials listed by the manufacturer are cast iron and steel. The stub-length configuration improves rigidity in short-reach applications, reducing deflection when drilling through harder ferrous stock. It is a single-piece replacement bit sold individually and is appropriate for production environments or maintenance shops running steel fabrication or machining operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDIN 1897 stub-length design increases rigidity and reduces deflection in ferrous drilling\u003c\/li\u003e\n\u003cli\u003eM2 high-speed steel construction provides heat resistance and edge retention in steel and cast iron\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web thinning for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral geometry promotes chip evacuation in through-hole and blind-hole applications\u003c\/li\u003e\n\u003cli\u003eMaximum drilling depth of 21.21 mm (0.835 inches) per DIN 1897 specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 1897 stub-length replacement drill bit for use in standard drill chucks and collet systems accepting a 6.53 mm straight-cylindrical shank.

Secure the shank fully in the chuck or collet before operation, and verify runout before cutting. Ensure the drilling machine spindle is stopped and locked out before changing tooling. Do not use this bit on materials outside the manufacturer-specified workpiece range, as doing so may cause premature wear or tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2571 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel, Grade M2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine Length)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 70 mm (2.756 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 31 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 21.21 mm (0.835 inches)\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: 6.53 mm (0.2571 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 39 mm (1.535 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.022 mm\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 1897\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 223\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.033 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: 9002230065300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732483277106,"sku":"9002230065300","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/904dac180efa792669a11db9279f6fd4_706956d9-d52c-4e2d-b43b-d1e7fb559b86.jpg?v=1788743463","url":"https:\/\/voomisupply.com\/products\/guhring-9002230065300-stub-drill-bit-letter-f-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
