Built to a wire gauge size of 12 with a titanium nitride (TiN) coating, this bit delivers extended wear resistance and reduced friction at the cutting edge. The straight flute geometry suits drilling in materials that produce short, manageable chips. At 2.25 inches overall length, the screw machine format provides added rigidity over jobber-length bits, making it well suited for production drilling and tight-clearance setups. Licensed machinists, tool-and-die shops, and maintenance technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis bit is used in screw machine operations, CNC drilling fixtures, drill presses, and hand-held power tools where a compact, rigid drill is required. The short overall length reduces deflection during entry, which is important in repetitive production cycles or when drilling harder alloys such as stainless steel, titanium, and high-strength steel. The TiN coating extends tool life compared to uncoated high-speed steel tooling, making it a cost-effective option for moderate- to high-volume applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction provides heat resistance for drilling hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends cutting life\u003c\/li\u003e\n\u003cli\u003eWire size 12 diameter for precision-gauged hole requirements\u003c\/li\u003e\n\u003cli\u003eStraight flute design promotes clean chip evacuation in short-chipping materials\u003c\/li\u003e\n\u003cli\u003eScrew machine length (2.25 inches OAL) delivers rigidity and reduced deflection\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 for use in standard drill chucks accepting a straight-cylindrical shank.

Secure the shank fully in the chuck and verify concentricity before drilling. Ensure the workpiece is clamped or fixtured before beginning the cut. Use appropriate cutting fluid or coolant for the material being drilled to maximize tool life, noting this bit does not feature through-coolant capability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.1875 inches\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: 0.19 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: YG-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: D4148112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"YG-1","offers":[{"title":"Default Title","offer_id":67909045190962,"sku":"D4148112","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/15a42e6b2ab428e3e537695d0c14b09d.jpg?v=1791185545","url":"https:\/\/voomisupply.com\/products\/yg-1-d4148112-cobalt-screw-machine-drill-bit-wire-12","provider":"Voomi Supply","version":"1.0","type":"link"}
