Measuring 1\/16 inch in diameter with a 3-inch overall length and a 1-3\/4 inch flute length, this bit features a 135-degree split point geometry that reduces walking and allows drilling without a center punch in many applications. A TiAlN (Titanium Aluminum Nitride) coating improves heat resistance and extends tool life when cutting through tough workpiece materials. The straight cylindrical shank provides secure chuck engagement, and the right-hand spiral flute efficiently evacuates chips during the cut. It is sold individually per package.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for metalworking applications requiring tight-tolerance holes in alloy steel and stainless steel. The taper length body provides additional rigidity compared to jobber-length bits, making it a practical choice for production drilling, maintenance and repair work, and toolroom applications. The web-thinned, tapered web configuration reduces thrust requirements, which is especially valuable when drilling harder grades of stainless steel or high-alloy materials where heat buildup and tool deflection are common concerns.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction provides elevated red hardness for cutting stainless steel and alloy steel\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating increases surface hardness and thermal resistance for longer tool life at higher speeds\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces drill walking and lowers required feed force\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web design reduces drilling thrust and heat generation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks accepting a 1\/16 inch straight cylindrical shank.

Secure the shank firmly in a drill press or handheld drill chuck before use and verify the workpiece is properly clamped. Use appropriate cutting fluid or coolant when drilling stainless steel or high-alloy materials to manage heat and extend tool life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-3\/4 inches\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\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 1\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 74146432\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51742447272242,"sku":"74146432","price":95.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b658fefe0deb1b92fe2cd73553bc0913.jpg?v=1788837529","url":"https:\/\/voomisupply.com\/products\/hertel-74146432-cobalt-drill-bit-1-16-in-135-point-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
