Manufactured from high-speed steel (HSS) with an oxide finish, it measures 1\/16 inch in diameter with a 135-degree split point that reduces walking and requires no center punch on most work surfaces. The straight-cylindrical shank seats securely in standard drill chucks. At 1-7\/8 inches overall length, this short mechanics-length geometry provides added rigidity and reduced deflection compared to jobber-length bits. Machinists, maintenance technicians, and trade professionals reaching into confined spaces or working on drill presses will find the compact profile practical for everyday metal drilling tasks.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloys, and stainless steel. Its general-purpose rating makes it a standard production and maintenance floor item. The mechanics-length body suits applications where a jobber-length bit would flex or chatter, such as short-reach drilling on machine components, fixture work, or field repair tasks. A right-hand spiral flute with web-thinned parallel web geometry aids chip evacuation and reduces thrust load during drilling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces bit walking and lowers required feed pressure\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles carbon steel, cast iron, stainless steel, and high alloy materials\u003c\/li\u003e\n  \u003cli\u003eMechanics length (1-7\/8 inches OAL) delivers greater rigidity and less deflection than jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eOxide coating provides mild lubricity and corrosion resistance during storage and use\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web reduces cutting resistance and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard 3-jaw drill chucks without adaptation\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 any standard drill chuck accepting a straight-cylindrical shank.

Secure the shank fully in the drill chuck before operation and verify chuck tightness to prevent slippage. When drilling stainless steel or high alloy materials, use appropriate cutting fluid to manage heat buildup and extend cutting edge life. Inspect the cutting edges before each use and replace if chipping or dulling is observed to maintain hole quality and avoid workpiece damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1\/16 inch (0.0625 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7\/8 inch\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: 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\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Carbon Steel, Cast Iron, High Alloy Steel, High Tensile Strength Alloy, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: BDNA--20900-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51723788648754,"sku":"BDNA--20900-1","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3a8dbbb1c415ef717da8d1609f8c4bd.jpg?v=1788608170","url":"https:\/\/voomisupply.com\/products\/import-bdna-20900-1-mechanics-drill-bit-1-16-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
