The cobalt alloy raises heat resistance significantly, allowing the bit to maintain cutting efficiency at temperatures exceeding 1,000 degrees Fahrenheit. The 135-degree split point features four cutting edges that initiate contact quickly and resist walking on the workpiece surface without a center punch. This bit is intended for professional use in metalworking applications where standard HSS bits lose hardness and edge life prematurely.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for drilling into hard and difficult-to-machine metals encountered in trade and fabrication work. Recommended materials include heat-treated steel, stainless steel, chrome alloy steel, manganese steel, titanium, and armor plate. It is well suited for HVAC equipment fabrication, plumbing rough-in through hard metal substrates, electrical panel work, and general mechanical assembly where hard metal penetration is required. The jobber length format fits standard three-jaw drill chucks on both corded and cordless tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8 percent cobalt content delivers heat resistance above 1,000 degrees Fahrenheit for sustained cutting in hard metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with four cutting edges reduces thrust and prevents bit walking at contact\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel base provides toughness and edge retention across a wide range of metal substrates\u003c\/li\u003e\n  \u003cli\u003eJobber length and straight shank fit standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eSuitable for stainless steel, heat-treated steel, chrome, manganese steel, titanium, and armor plate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard three-jaw drill chucks accepting straight-shank jobber-length bits.

Secure the workpiece firmly to prevent movement during drilling. Apply cutting fluid or oil when drilling stainless steel or other work-hardening alloys to extend bit life and reduce heat buildup. Inspect the cutting edges for wear before each use and replace the bit if the split point shows chipping or rounding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBit Diameter\u003c\/strong\u003e: 7\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees split point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High speed steel with 8 percent cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Style\u003c\/strong\u003e: Jobber length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Weight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.75 inches x 1.85 inches x 1.52 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\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: DISSTON COMPANY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 571216\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DISSTON CO","offers":[{"title":"Default Title","offer_id":51723582243122,"sku":"571216","price":24.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/986fc0b1d2f40322f41cdd056d5c624a.jpg?v=1788606678","url":"https:\/\/voomisupply.com\/products\/disston-company-571216-cobalt-hss-drill-bit-7-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
