It features a 135-degree split point geometry with web thinning, which reduces walking on contact and lowers the thrust force needed to start a cut. The straight-cylindrical shank fits standard three-jaw drill chucks without modification. At 0.159 inches in diameter and 3.25 inches overall length, this bit is suited for production and maintenance drilling where clearance is limited and a jobber-length bit would be excessive.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in metal fabrication, mechanical maintenance, and industrial service environments. It performs well in carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel workpieces. The mechanics length makes it a practical choice in confined spaces such as equipment frames, enclosures, and mechanical assemblies where a standard jobber-length bit cannot be used effectively. Licensed tradespeople and machine operators handling metal fabrication and repair work are the primary installers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces bit walking and lowers entry thrust on hard metals\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned geometry improves chip clearance and cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction withstands heat generated during metal drilling\u003c\/li\u003e\n  \u003cli\u003eOxide finish provides moderate corrosion resistance and reduced friction\u003c\/li\u003e\n  \u003cli\u003eMechanics length (3.25 inches OAL) suited for confined-space drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flutes with regular helix for consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose mechanics-length drill bit compatible with standard three-jaw drill chucks accepting straight-cylindrical shanks, for use in drilling carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel workpieces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, HVAC technicians, and mechanical maintenance tradespeople using standard drill presses, handheld electric drills, or magnetic-base drills. Secure the workpiece fully before drilling to prevent movement. Use appropriate cutting fluid or coolant when drilling stainless or high-alloy steel to manage heat buildup, even though this bit does not support through-coolant delivery. Inspect the cutting edges for wear before each use and replace when the split point shows visible rounding or chipping.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.159 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2 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 Point\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\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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: IMPORT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20821\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51691844010290,"sku":"20821","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d797d0de37c552a79c005d0918c8c29.jpg?v=1788290370","url":"https:\/\/voomisupply.com\/products\/import-20821-mechanics-drill-bit-0-159-in-hss-split-point","provider":"Voomi Supply","version":"1.0","type":"link"}
