It features a 31\/64-inch (0.4844 inch decimal) drill diameter with a 3\/8-inch straight-cylindrical reduced shank, allowing it to fit standard 3\/8-inch chucks while drilling a larger hole. The 135-degree split point reduces walking and enables faster penetration without a center punch on most metals. Constructed from high speed steel with a coated finish, this bit is designed for durability and heat resistance under continuous use. It is suited for licensed tradespeople and shop technicians who need reliable, consistent performance in production or field drilling tasks.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for right-hand cutting in a range of ferrous and tough alloy materials. Primary workpiece materials include carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and tough alloy. The T8HD series designation places it in a jobber-reduced shank class built for general-purpose drilling where standard shanks are too large for available chuck capacity. Typical install scenarios include HVAC bracket fabrication, electrical panel work, plumbing rough-in drilling through metal studs or strut, and mechanical room metalwork.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e31\/64-inch drill diameter with 3\/8-inch reduced straight-cylindrical shank for use in standard 3\/8-inch chucks\u003c\/li\u003e\n  \u003cli\u003e135-degree split point minimizes bit walking and reduces required feed pressure\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides heat resistance during continuous drilling cycles\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends surface life and reduces friction during cutting\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular spiral type for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMaximum drilling depth of 4.38 inches on compatible materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 3\/8-inch keyed or keyless drill chucks; compatible with carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and tough alloy workpieces.

Secure the workpiece before drilling and verify the chuck is fully tightened on the shank before applying power. Do not exceed recommended drill press or hand drill RPM ranges for the workpiece material and bit diameter. Inspect the cutting edges before each use and replace the bit if chipping, burning, or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 31\/64 inch (0.4844 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical Reduced Shank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 4.38 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T8HD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Carbon Steel, Cast Iron, High Alloy Steel, High Tensile Strength Alloy, Stainless Steel, Steel, Tough Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Required\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TRIUMPH TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 092131\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRIUMPH TWIST DRILL","offers":[{"title":"Default Title","offer_id":67907370746162,"sku":"092131","price":28.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f278cf157d7581eb8a0e491616fb3cc.jpg?v=1791178628","url":"https:\/\/voomisupply.com\/products\/triumph-twist-drill-092131-reduced-shank-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
