Each bit in the M40CO series features a 135-degree split-point tip that self-centers on contact, reducing walking and the need for a center punch. The cobalt construction handles hard and abrasive metals that would wear out standard high-speed steel bits. A gold finish indicates the cobalt-enriched alloy blend. Straight shanks fit standard drill chucks, and the screw machine length profile provides added rigidity and control in drill presses and handheld power tools. The set covers sizes from 1\/16 inch to 1\/2 inch in 1\/64-inch step increments, stored in a metal case.\u003c\/p\u003e\n\u003cp\u003eThis set is intended for trade professionals and industrial users working with steel, stainless, cast iron, and other hard materials. Screw machine length bits are shorter than jobber-length bits, making them the preferred choice in tight-clearance applications, production drilling, and CNC or drill press setups where flex and deflection need to be minimized. The 29-piece range covers the full fractional inch progression from 1\/16 inch through 1\/2 inch, making it suitable for general fabrication shops, maintenance mechanics, plumbers, and HVAC techs drilling through metal framing and hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt (M40CO series) construction for extended life in hard and abrasive metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split-point tip self-centers and reduces drill walking without a center punch\u003c\/li\u003e\n  \u003cli\u003eScrew machine length profile increases rigidity and reduces deflection versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eCovers 1\/16 inch to 1\/2 inch in 1\/64-inch step increments — 29 pieces total\u003c\/li\u003e\n  \u003cli\u003eStraight shank fits standard three-jaw drill chucks\u003c\/li\u003e\n  \u003cli\u003eGold finish alloy-indicator coating; metal storage case included\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI specification standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-shank drill chucks on drill presses, handheld power drills, and CNC equipment.

Secure the workpiece before drilling and confirm the chuck is tightened fully around the straight shank before starting the tool. Use cutting fluid or coolant when drilling hard metals to extend bit life, even though coolant-through is not built into this bit design. Inspect each bit for wear or tip damage before use and replace any bit that shows cracking or excessive wear at the cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: M40CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 29\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\u003eShank Type\u003c\/strong\u003e: Straight Shank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Gold Finish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Bit Size\u003c\/strong\u003e: 1\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Bit Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStep Increments\u003c\/strong\u003e: 1\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine Length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Metalworking, Multipurpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStorage Unit Type\u003c\/strong\u003e: Metal Case\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5995616\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51712170885426,"sku":"5995616","price":484.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/16f0882695411c8f40f8f9f0da4e3faa.jpg?v=1788484654","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5995616-cobalt-drill-bit-set-29pc","provider":"Voomi Supply","version":"1.0","type":"link"}
