Built from C2 carbide with a bright, uncoated finish, this 3\/16 inch (0.1875 inch) diameter bit features a 140-degree notched point and web-thinned geometry that reduces thrust and improves chip clearance in tough materials. The straight-flute design is well suited for short-chipping materials where a standard spiral flute would pack and bind. Machinists, tool and die technicians, and metalworking professionals reach for this bit when working in hard, exotic, or abrasion-resistant alloys that demand rigidity and edge retention over a standard high-speed steel bit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for use in chrome alloy, heat-treated alloy, nickel alloy, stainless steel, carbon steel, and titanium alloy workpieces, making it a reliable choice for aerospace, automotive, and industrial fabrication setups. It performs in both production drilling on CNC machining centers and manual drilling on knee mills or drill presses where precise, repeatable hole sizing is required. The 3\/16 inch shank diameter matches the bit body, allowing it to seat directly in standard collets and drill chucks without a reduction sleeve.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eC2 carbide construction delivers hardness and wear resistance in abrasive and high-strength alloys\u003c\/li\u003e\n  \u003cli\u003e140-degree notched point reduces walking and minimizes the need for a center punch on hard stock\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned geometry lowers cutting thrust and extends tool life in difficult materials\u003c\/li\u003e\n  \u003cli\u003eStraight-flute design handles short-chipping materials such as stainless steel and titanium alloy without packing\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish maintains dimensional accuracy and suits applications where coatings may interfere with tolerances\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches ensures consistent, on-size holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard drill chucks and collet holders accepting a 3\/16 inch straight shank.

Carbide is brittle compared to high-speed steel  -  avoid interrupted cuts or side-loading that can chip the cutting edge. Apply appropriate cutting fluid for the workpiece material to manage heat and extend tool life. Inspect the cutting edges and point before each use; do not run a chipped carbide bit, as edge failure can damage the workpiece and create a safety hazard.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Type\u003c\/strong\u003e: Straight-Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Notched\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Carbide, Grade C2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Chrome Alloy, Heat-Treated Alloy, Nickel Alloy, Stainless Steel, Steel, Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74129198\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744432914738,"sku":"74129198","price":42.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/845693d84553317728845bb965245e24.jpg?v=1788856436","url":"https:\/\/voomisupply.com\/products\/hertel-74129198-straight-flute-drill-bit-3-16-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
