Built from cobalt high-speed steel and coated with TiAlN for extended tool life at elevated cutting temperatures, this bit features a 135-degree split point that reduces walking and requires no center punch on most surfaces. The straight cylindrical shank measures 3\/16 inch in diameter, the flute length is 3-3\/8 inches, and the overall length is 5-3\/4 inches. The right-hand spiral flute with a tapered web configuration and web thinning promotes efficient chip evacuation during deep-hole drilling operations.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling alloy steel and stainless steel in metalworking, fabrication, and maintenance applications. The taper length body provides additional reach compared to a jobber-length bit while maintaining rigidity, making it a practical choice for production drilling, toolroom work, and field repair situations where material hardness demands a cobalt-grade tool. It is sold and packaged individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool material provides heat resistance and durability in hard metals\u003c\/li\u003e\n\u003cli\u003eTiAlN coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003e135-degree split point minimizes bit walking and reduces thrust required\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web for improved chip flow and reduced torque\u003c\/li\u003e\n\u003cli\u003eRight-hand cut spiral flute for standard drill press and hand-drill operation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in alloy steel and stainless steel applications.

Secure the workpiece firmly before drilling and use cutting fluid rated for cobalt tooling when drilling stainless or alloy steel to maximize bit life. Inspect the cutting edges before each use and replace if chipping or excessive wear is observed. Follow applicable workplace safety standards for rotating machinery during all drilling operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\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\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-3\/4 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: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 74146515\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51740418081074,"sku":"74146515","price":22.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a7d0b5d914fadfd01c57a6f0d251c9f9.jpg?v=1788824877","url":"https:\/\/voomisupply.com\/products\/hertel-74146515-cobalt-taper-length-drill-bit-3-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
