It features a standard 118-degree split point with web thinning on a tapered web, which helps center the bit and reduces the thrust needed to start a hole. The oxide coating provides light corrosion resistance and reduces friction during cutting. With an overall length of 4.875 inches and a 3.5-inch spiral flute, this is a general-purpose two-flute bit suited for production drilling in steel, cast iron, and similar ferrous materials. Licensed tradespeople and machinists reach for this size when fractional and metric sizes fall short of the required hole diameter.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for right-hand rotation and straight-cylindrical shank mounting, making it compatible with standard drill chucks on drill presses, portable electric drills, and CNC machines fitted for straight-shank tooling. The regular spiral flute geometry promotes consistent chip evacuation in through-hole and blind-hole applications in steel and cast iron. It is a general-purpose grade suited for maintenance, repair, fabrication shops, and light production environments where letter-size hole tolerances are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter T size — 0.3580 inch decimal equivalent for precise letter-series hole tolerances\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web thinning for reduced entry thrust and improved centering\u003c\/li\u003e\n\u003cli\u003eHigh speed steel (HSS) construction withstands heat generated in steel and cast iron drilling\u003c\/li\u003e\n\u003cli\u003eOxide coating reduces friction and provides light surface protection\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry with tapered web promotes reliable chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill bit for use in standard straight-shank drill chucks on drill presses, hand drills, and CNC equipment.

Secure the straight shank fully in the chuck and verify concentricity before drilling to prevent bit walk. Always power down and lock out the machine before changing tooling. Use appropriate cutting fluid or coolant on ferrous workpieces to extend bit life, even though this bit does not support internal coolant-through delivery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3580 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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit 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\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3580 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered with Web Thinning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\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: 0.09 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: 01189208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689646653746,"sku":"01189208","price":60.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3a4552107249e0893e239ce4a89aa16.jpg?v=1788262348","url":"https:\/\/voomisupply.com\/products\/value-collection-01189208-letter-t-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
