Built from M2 high speed steel with an oxide coating for reduced friction and improved chip flow, this bit features a 118-degree standard point angle and a web-thinned, tapered web configuration for easier penetration and reduced thrust. The straight-cylindrical shank measures 12.80 mm in diameter, making it compatible with standard drill chucks. With an overall length of 151 mm and a flute length of 101 mm, this bit delivers reliable performance in a wide range of production and maintenance drilling tasks.\u003c\/p\u003e\u003cp\u003eThis drill bit suits metalworking professionals, machinists, and maintenance technicians working in industrial, commercial, and shop environments. The DIN 338 specification ensures dimensional consistency and interchangeability with tooling setups that call for metric jobber length bits. The right-hand spiral flute design efficiently evacuates chips during through-hole and blind-hole drilling operations in steel, cast iron, and similar materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM2 high speed steel construction for durability in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eOxide coating reduces friction and extends tool life between resharpening intervals\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 12.80 mm diameter fits standard drill chucks\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 338 specification for consistent metric jobber length dimensions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 338 metric jobber length drill bit, this tool fits standard drill chucks and drilling equipment configured for a 12.80 mm straight-cylindrical shank within the 12.50 mm to 15.00 mm drill bit size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with drill press, CNC, or hand-drill operation. Ensure the machine spindle is fully stopped and power is disconnected before changing tooling. Secure the shank firmly in the chuck to the full gripping depth to prevent runout or slippage during operation. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed settings based on workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 12.80 mm (0.5039 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 151 mm (5.945 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 101 mm (3.976 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12.80 mm (0.5039 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: 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\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\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\u003eMaterial\u003c\/strong\u003e: M2 High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Oxide\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 -0.027 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.231 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: 9002050128000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732032454962,"sku":"9002050128000","price":46.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83d69f89c46fbc452b6fc7bec513ac36_3dc374e6-3058-4090-afc5-52dd7016acca.jpg?v=1788738429","url":"https:\/\/voomisupply.com\/products\/guhring-9002050128000-jobber-drill-bit-12-8mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
