It measures 29\/64 inches (0.4531 inches) in diameter with a 4-5\/8 inch overall length and a 3-inch flute length. The 135-degree split point geometry reduces walking on contact and requires no center punch on most surfaces. Constructed from high-speed steel with an oxide finish, this bit handles demanding drilling tasks in production and maintenance environments. The Weldon flat shank with three flats prevents rotation in the chuck during high-torque applications.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel stock. The mechanics-length body fits standard drill presses, handheld electric drills, and magnetic-base drills where a shorter overall length is preferred over jobber-length bits. It is a common choice for machinists, millwrights, and maintenance technicians working in fabrication shops or on-site mechanical service where controlled hole entry and accurate sizing are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces thrust force and self-centers on contact without a pilot punch\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction maintains hardness and edge retention at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank with three flats locks securely in set-screw chucks to prevent slippage under torque\u003c\/li\u003e\n  \u003cli\u003eOxide surface finish provides mild corrosion resistance and reduces friction during cutting\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web configuration improves chip evacuation and cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eMechanics-length body (4-5\/8 inches OAL) offers greater rigidity and control compared to jobber-length bits\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 Weldon flat set-screw chucks on standard drill presses and handheld drills.

Ensure the workpiece is clamped or fixtured before drilling to prevent rotation and injury. Apply cutting fluid when drilling stainless steel or high-alloy materials to extend tool life and maintain cut quality. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is evident.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 29\/64 inches (0.4531 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 3\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)\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\u003eLength Type\u003c\/strong\u003e: Mechanics\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20925\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709957800242,"sku":"20925","price":78.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a4b1d849e6fbcf9023af13c7d171704.jpg?v=1788462563","url":"https:\/\/voomisupply.com\/products\/value-collection-20925-29-64-in-mechanics-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
