Built from high-speed steel (HSS) with an oxide coating, this bit delivers reliable performance in production and maintenance environments. It measures 2.5 inches in overall length with a 1.375-inch flute length, making it shorter and more rigid than jobber-length bits — ideal for drill press, CNC, and hand-drill applications where chatter and deflection need to be minimized. The standard 118-degree point angle suits a wide range of common materials. Licensed trades and production machinists rely on this geometry for consistent, repeatable results.\u003c\/p\u003e\u003cp\u003eThis screw machine drill bit is suited for general-purpose drilling in light manufacturing, maintenance, and repair operations. Its compact length improves rigidity when working in confined spaces or on drill press setups. The Letter B designation corresponds to a decimal diameter of 0.238 inches, placing it in the 0.200 to 0.250 inch size range. The straight cylindrical shank fits standard drill chucks without adapters. It is sold individually and is commonly used by machinists, HVAC technicians, pipefitters, and electricians for pilot holes, clearance holes, and light metalwork.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter B size — 0.238 inches decimal equivalent for precise hole sizing\u003c\/li\u003e\n\u003cli\u003eHSS construction with oxide coating for improved wear and heat resistance\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose material compatibility\u003c\/li\u003e\n\u003cli\u003eScrew machine length (2.5 inches OAL) for enhanced rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web for easier penetration and reduced thrust\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting with regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose screw machine length drill bit compatible with any standard drill chuck accepting a straight cylindrical shank in the 0.238-inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by licensed machinists, tradespeople, and qualified maintenance technicians. Secure the straight shank firmly in a calibrated drill chuck before use and verify chuck key is removed before powering the drill or press. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and replace the bit if chipping or dullness is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.238 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.034 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 01359025\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695141028146,"sku":"01359025","price":57.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cdace9422c1935c35381b5ee47991e35.jpg?v=1788331653","url":"https:\/\/voomisupply.com\/products\/value-collection-01359025-letter-b-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
