It carries a 140-degree point angle with an R-thinned web for improved self-centering and reduced thrust. The WD1 coating adds wear resistance and heat tolerance during high-cycle production runs. The bit measures 10.7 mm in diameter with a 12.0 mm straight-cylindrical shank, an overall length of 118.0 mm, and a flute length of 71.0 mm. Two spiral flutes in a regular helix promote chip evacuation in deep-hole applications. Coolant-through capability makes it suited for flood or through-spindle coolant delivery on CNC machining centers and drill presses.\u003c\/p\u003e\u003cp\u003eThis bit is designed for drilling into steel, alloy steel, and cast iron in production and job-shop environments. Typical applications include blind holes, cross holes, and through-hole drilling where self-centering entry and consistent diameter tolerance are required. The 5xD flute-to-diameter ratio supports moderate-depth holes without packing chips. Machinists and tool-and-die professionals working on steel fabrication, automotive components, and general metalworking will find this bit suited to high-volume drilling cycles where solid carbide outperforms high-speed steel in tool life.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with R-thinned web for self-centering entry and lower thrust\u003c\/li\u003e\n\u003cli\u003eWD1 coating provides wear and heat resistance during high-cycle drilling\u003c\/li\u003e\n\u003cli\u003eCoolant-through design compatible with through-spindle or flood coolant systems\u003c\/li\u003e\n\u003cli\u003e5xD flute ratio supports blind-hole and cross-hole applications\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.007 to +0.025 mm for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in steel, alloy steel, and cast iron workpieces.

Secure the straight-cylindrical shank in a collet or drill chuck rated for the shank diameter before operation. Through-spindle coolant connections should be verified and leak-checked before running. Follow the machine tool manufacturer and OSHA guidelines for proper workholding and RPM limits when drilling ferrous materials with solid carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 10.7 mm (0.4213 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 118.0 mm (4.646 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 71.0 mm (2.795 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12.0 mm (0.472 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 Helix\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: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: WD1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.007 to +0.025 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HP255\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.29 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HP255-4213\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51747650568498,"sku":"HP255-4213","price":369.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/572ef8849892055a6801dc3158bc150f_863db82d-bfe0-4c40-89b4-571e0a1d4a44.jpg?v=1788884063","url":"https:\/\/voomisupply.com\/products\/osg-hp255-4213-solid-carbide-jobber-drill-bit-10-7-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
