The 3\/32-inch diameter bit features a 135-degree split point that reduces walking on entry and lowers thrust force at the start of the cut. A TiAlN coating adds heat resistance and extends tool life when drilling hardened steels, stainless, and high-temperature alloys. At 1.75 inches overall length, the screw machine geometry keeps the tool rigid and accurate in close-clearance work. Machinists, tool and die technicians, and industrial maintenance mechanics are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit suits production drilling on CNC machining centers, turret lathes, drill presses, and hand-held pneumatic or electric tools where short, stiff tooling is preferred. The right-hand cut and spiral flute configuration handles a wide range of metals including carbon steel, alloy steel, cast iron, and stainless steel. It is a practical choice for shop environments that run high cycle counts and need consistent hole quality without frequent tool changes. The 0.0938-inch decimal diameter makes it compatible with standard 3\/32-inch drill chucks and collet systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material provides superior heat resistance compared to standard high-speed steel\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating extends tool life in abrasive and high-temperature cutting conditions\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and minimizes drill walk on entry\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (1.75 inches OAL) delivers rigidity in tight-clearance setups\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web improves chip evacuation and cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute for standard clockwise spindle rotation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/32-inch screw machine length drill bit compatible with any chuck or collet system accepting a straight-cylindrical shank at that diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance mechanics familiar with rotating cutting tool safety. Secure the shank fully in the chuck or collet and verify runout before beginning a cut. Always power down and de-energize the spindle before changing or inspecting tooling. Do not exceed the recommended speed and feed range for cobalt-coated bits in the material being drilled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/32 inches (0.0938 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 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\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Parallel, Web-Thinned\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: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: 74131392\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743460393266,"sku":"74131392","price":43.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c15cadbed57eb882d67bd107287edfda.jpg?v=1788847252","url":"https:\/\/voomisupply.com\/products\/hertel-74131392-cobalt-screw-machine-drill-bit-3-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
