Built from powdered metal (PMASP60 grade) with a coated finish, it delivers extended tool life compared to standard HSS tooling. The bit features a parabolic flute geometry that promotes efficient chip evacuation, and a 130-degree drill point angle suited for harder ferrous materials. Web thinning reduces entry force and improves centering accuracy. At 0.42 inches (27\/64 inch) in diameter, this bit fits standard drill chucks and CNC toolholders with a straight-cylindrical shank. It is intended for machinists, tool-room operators, and production floor technicians.\u003c\/p\u003e\u003cp\u003eThis stub-length drill bit is built for applications where rigidity matters more than reach, including short-hole drilling on machining centers, drill presses, and screw machines. Its compact flute length reduces deflection in interrupted cuts and tight setups. Primary workpiece materials are cast iron and steel. The 3xD flute-to-diameter ratio and parabolic flute form support faster feed rates in production environments. The bit conforms to DIN 1897 specifications, making it a direct fit for metric and imperial mixed-tolerance setups common in precision machining shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e27\/64 inch (0.4200 inch) diameter with a tight tolerance of +0.000 to -0.027 mm\u003c\/li\u003e\n\u003cli\u003e130-degree cone relief point angle optimized for cast iron and steel drilling\u003c\/li\u003e\n\u003cli\u003eParabolic flute design promotes fast chip evacuation and reduced heat buildup\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel web configuration reduces thrust force at entry\u003c\/li\u003e\n\u003cli\u003ePowdered metal PMASP60 construction with coated finish for extended wear resistance\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 1897 stub drill standard for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style stub drill conforming to DIN 1897, compatible with standard straight-shank drill chucks and collet systems used on drill presses, CNC machining centers, and screw machines.

Secure the straight-cylindrical shank fully within the chuck or collet before tightening to manufacturer-recommended holding specifications. Inspect the cutting edges and coating condition before each use; a chipped or worn edge on a stub drill can cause workpiece damage or sudden tool failure. Always observe applicable shop safety standards and machine tool operating procedures when setting feeds and speeds for the target material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 27\/64 inch (0.4200 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 89.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 43.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.2170 inches (30.92 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: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cone Relief\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Powdered Metal (PMASP60)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.027 mm\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\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\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine Length)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 515\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 9005150107200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732789461298,"sku":"9005150107200","price":101.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c006652175d01a95e2cb0b47a6c8c97c.jpg?v=1788746832","url":"https:\/\/voomisupply.com\/products\/guhring-9005150107200-stub-drill-bit-27-64-in-powdered-metal","provider":"Voomi Supply","version":"1.0","type":"link"}
