It features a 2.20 mm (0.0866 inch) cutting diameter, a 140-degree point angle with R-thinned web geometry, and an overall length of 52.00 mm. The WD1 coating improves wear resistance and heat dissipation during aggressive drilling cycles. With a regular spiral flute, right-hand cutting direction, and straight-cylindrical shank, this bit is built for consistent hole quality in production and maintenance environments. Machinists and toolroom technicians working on precision components will find this drill well-suited to tight-tolerance applications.\u003c\/p\u003e\u003cp\u003eThis drill is intended for use in CNC machining centers, drill presses, and similar equipment where small-diameter, high-accuracy holes are required. Primary workpiece materials include steel, alloy steel, and cast iron (ISO material codes P and K). It supports blind hole drilling, cross-hole drilling, and self-centering applications. The 5xD flute-to-diameter ratio provides adequate chip evacuation in short-to-moderate depth holes without through-coolant. It is sold individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard ferrous materials\u003c\/li\u003e\n\u003cli\u003eWD1 coating for extended tool life and reduced built-up edge\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with R-thinned web for reduced thrust and improved self-centering\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 3.00 mm diameter for standard collet and chuck compatibility\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.002 to +0.012 mm for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling steel, alloy steel, and cast iron workpieces.

Secure the straight-cylindrical shank firmly in a collet or drill chuck before operation to prevent runout that can cause bit breakage at this diameter. Carbide is brittle — avoid lateral loads, interrupted cuts without proper setup, and contact with hard inclusions without confirming material suitability. Ensure spindle runout is within acceptable limits before use, as excessive runout dramatically reduces tool life in sub-3 mm carbide drills.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.20 mm (0.0866 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 52.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 20.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.002 to +0.012 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HP245\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: HP245-0866\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51750672793906,"sku":"HP245-0866","price":45.22,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17fac3bcdd49fd228104c77863b3f6e3_2a76e7fb-7dc8-4c1e-a950-8216d5e67553.jpg?v=1788918215","url":"https:\/\/voomisupply.com\/products\/osg-hp245-0866-solid-carbide-jobber-drill-2-20-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
