The titanium nitride (TiN) coated can prevent further oxidation or corrosion of the drill bits and extend the service life.\u003c\/li\u003e\n\u003cli\u003eAPPLICATION: The M2 high-speed steel drill bit delivers superior all-around performance, making it the optimal choice for most metal drilling applications, including low\/medium-carbon steel, alloy steel, stainless steel, cast iron, and aluminum alloys. When drilling harder materials such as high-carbon steel, stainless steel, and alloy steels, is recommended to use a coolant to reduce wear\u003c\/li\u003e\n\u003cli\u003eNOTE: Position the twist drill at 90° to the workpiece. For thick materials, drill in multiple passes to prevent overheating or breakage. For large holes, start with a guide hole. Use cutting fluid to improve efficiency, extend tool life, and reduce material damage.\u003c\/li\u003e\n\u003cli\u003eINSTRUCTION: When machining different materials, the spindle speed and feed rate vary. Generally, the harder the material, the lower the spindle speed and feed rate should be. For specific speed and feed rate recommend for common materials, please refer to the details provided on the product page.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOverview\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter:\u003c\/strong\u003e 11 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Type:\u003c\/strong\u003e Titanium Nitride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type:\u003c\/strong\u003e Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Angle String:\u003c\/strong\u003e 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e PATIKIL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PATIKIL","offers":[{"title":"Default Title","offer_id":50560657096923,"sku":"B0F66LFLD5-size-11mm","price":23.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0846\/0917\/1675\/files\/41Xi3KsTWHL.jpg?v=1791073212","url":"https:\/\/spruvexa.com\/products\/patikil-11mm-drill-bit-jobber-straight-shank-m2-tin-coated-4pcs-size-11mm","provider":" Spruvexa","version":"1.0","type":"link"}
