Built from cobalt high-speed steel with a TiAlN coating, this bit handles elevated cutting temperatures and extends tool life compared to standard HSS bits. The 135-degree split point reduces walking and allows the bit to cut on contact without a center punch. At 5\/32 inch (0.1562 inch) diameter with a 5-3\/8 inch overall length and 3-inch spiral flute, it is suited for through-hole and deeper-reach drilling tasks performed by machinists and metalworking tradespeople.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for drilling alloy steel and stainless steel in shop and field environments where standard length bits cannot reach. The taper length body provides added reach over jobber-length bits while maintaining rigidity. The straight cylindrical shank fits standard drill chucks and collet holders. Right-hand cut and spiral flute geometry clear chips efficiently during continuous drilling operations in ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction resists heat buildup during high-speed drilling in hard metals\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating increases surface hardness and reduces friction for extended tool life\u003c\/li\u003e\n  \u003cli\u003e135-degree split point starts on contact, reducing thrust force and eliminating walking\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration improves chip evacuation and reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eTaper length body provides additional reach over standard jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement taper length drill bit for use in standard 3-jaw drill chucks and collet systems accepting a 5\/32 inch straight cylindrical shank.

Secure the straight shank fully in the chuck with consistent clamping force before operation. Use appropriate cutting fluid or coolant when drilling stainless steel or alloy steel to manage heat, as this bit does not support coolant-through delivery. Follow applicable shop safety codes and machine manufacturer guidelines for speed and feed settings when using cobalt bits in hard materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/32 inch (0.1562 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3 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\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/32 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\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.27 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: 74146499\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743519408434,"sku":"74146499","price":21.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b2b490e8826fd13154f28cdfa9230db_4a6a4e2d-5f72-4871-9f81-1a78b3440b1f.jpg?v=1788847982","url":"https:\/\/voomisupply.com\/products\/hertel-74146499-taper-length-drill-bit-5-32-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
