Built for heavy-duty drilling applications, the bit features a 135-degree split point that reduces walking and requires no center punch on most workpieces. The regular spiral flute and right-hand cutting direction are standard for general-purpose drilling, while the cobalt construction gives the bit the heat resistance needed to cut through tough, work-hardening materials. Overall length is 2.75 inches with a 1.625-inch flute length. Machinists, maintenance technicians, and fabricators working with hardened or abrasive stock reach for cobalt-grade tooling like this when high-speed steel would overheat and dull prematurely.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling stainless steel, hardened materials, and other high-strength alloys where tool life and edge retention are critical. The straight cylindrical shank accepts standard drill chucks on handheld drills, drill presses, and CNC machining centers. The 0.1200-inch shank diameter matches the cutting diameter, making chuck runout straightforward to minimize. Applications include tapping prep, hole sizing for fasteners, and general metalworking in fabrication shops, maintenance facilities, and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction provides superior heat resistance for drilling stainless steel and hardened materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust force and minimizes bit walking without a center punch\u003c\/li\u003e\n  \u003cli\u003eWire gauge No. 31 size — 0.1200 inches decimal — for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, right-hand flute geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks without an adapter\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty grade construction rated for demanding production and maintenance use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard jobber-length drill bit compatible with any drill press, hand drill, or machining center chuck that accepts a 0.1200-inch straight shank.

Use appropriate cutting fluid or coolant when drilling stainless steel or hardened alloys to extend tool life and prevent work hardening at the hole edge. Reduce feed pressure as the bit breaks through the workpiece to avoid grabbing or bit breakage. This tooling should be installed and operated by personnel familiar with machine shop safety practices and applicable workplace standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 31\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Hardened Materials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 01198316\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718244794674,"sku":"01198316","price":50.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7568fbd08f400a994d2ffb781e873f93.jpg?v=1788551074","url":"https:\/\/voomisupply.com\/products\/value-collection-01198316-cobalt-jobber-drill-bit-no-31","provider":"Voomi Supply","version":"1.0","type":"link"}
