Built from cobalt high-speed steel and finished with a TiAlN coating, this bit handles elevated cutting temperatures that would degrade standard HSS tooling. The 135-degree split point geometry reduces thrust and self-centers on entry, minimizing the need for a center punch on flat stock. At 2.375 inches overall length, the shorter-than-standard body provides rigidity and reduces deflection in drill press, CNC turret, and screw machine applications. Wire size 3 corresponds to a decimal diameter of 0.2130 inches. Licensed machinists, tool-and-die technicians, and general metalworking shops are the primary users.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production drilling in stainless steel, alloy steel, cast iron, titanium, and other hard ferrous materials where heat buildup shortens tool life. The stub length format makes it a standard choice for turret lathes, automatic screw machines, and short-reach drill press setups where a jobber-length bit would flex or chatter. The web-thinned, parallel-web configuration reduces cutting resistance at the chisel edge, which is especially beneficial in interrupted cuts and when drilling through hardened plate. This is a right-hand cutting tool intended for conventional right-hand spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt HSS construction resists heat and wear in hard ferrous materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life in dry and semi-dry cutting conditions\u003c\/li\u003e\n\u003cli\u003e135-degree split point self-centers and reduces entry thrust\u003c\/li\u003e\n\u003cli\u003eStub screw machine length (2.375 inches OAL) provides rigidity and reduces deflection\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web lowers cutting resistance at the chisel edge\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drill presses, CNC turret machines, automatic screw machines, and hand-held power drills equipped with a standard straight-shank chuck accepting 0.2130-inch diameter tooling.

Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Secure the shank fully in the chuck or collet to the recommended grip depth to prevent pullout under load. Do not exceed the material manufacturer or machine manufacturer recommended feed and speed parameters for cobalt tooling in the workpiece material being drilled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDecimal Diameter\u003c\/strong\u003e: 0.2130 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\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 Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular Spiral Flute\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: 74132010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743227478322,"sku":"74132010","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aad441302e927d92c971be47840c8bf3.jpg?v=1788844183","url":"https:\/\/voomisupply.com\/products\/hertel-74132010-screw-machine-drill-bit-size-3-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
