Built from M42 or equivalent cobalt high-speed steel with a gold finish, these bits handle hard metals, stainless steel, cast iron, and other demanding materials that standard HSS tooling cannot manage reliably. The 135-degree split-point geometry starts on contact without a center punch, reduces walking on curved or sloped surfaces, and self-centers to keep hole location tight. The straight shank fits standard three-jaw chucks across benchtop drill presses, floor-standing machines, and handheld power drills. This set is a go-to for maintenance professionals, machinists, and multi-trade technicians who drill metal daily.\u003c\/p\u003e\u003cp\u003eThe 5995670 set is rated for heavy-duty metalworking and multipurpose drilling applications in both shop and field environments. Wire gauge sizing from 1 to 60 covers the full range of small-diameter holes commonly required in HVAC sheet metal work, electrical panel knockouts, plumbing rough-in, and general fabrication. The plastic indexed case keeps each bit organized and protected between uses, reducing time spent searching for a specific wire size on the job.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool material with gold finish for increased heat and wear resistance in hard-metal drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split-point tip self-centers on contact, eliminating the need for a center punch on flat stock\u003c\/li\u003e\n\u003cli\u003eStraight shank fits standard three-jaw chucks without adapters\u003c\/li\u003e\n\u003cli\u003eComplete wire gauge set from 1 to 60 in a single indexed plastic storage case\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and NAS 907 specification standards\u003c\/li\u003e\n\u003cli\u003eHeavy-duty performance rating for continuous metalworking use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any standard three-jaw chuck drill press or handheld power drill accepting straight shank bits sized within the wire gauge range of 1 through 60.

Secure workpieces firmly in a vise or clamp before drilling to prevent rotation. Use appropriate cutting fluid or coolant when drilling hard alloys or stainless steel to extend bit life, even though this set does not include coolant-through capability. Inspection and replacement of worn bits should follow standard shop maintenance practices.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R18CO\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: Gold Finish\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split-Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Shank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Jobber Length\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Sizes Included\u003c\/strong\u003e: Wire 1 to 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: ANSI, NAS 907\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: Indexed Plastic Case\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: 0.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5995670\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693990117682,"sku":"5995670","price":337.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3ad8a4487fd11f2f29e4f885f7e6ad0.jpg?v=1788319448","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5995670-cobalt-drill-bit-set-60-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
