Built from heavy-duty cobalt with a titanium nitride (TiN) coating, it delivers extended tool life in hard and abrasive materials. The 135-degree split point reduces walking and cutting thrust, making it well suited for drilling without a center punch. At 1-13\/16 inches overall length with a 13\/16-inch flute length, this stub-length geometry provides rigidity and minimizes deflection in short-reach setups. The straight-cylindrical shank fits standard drill chucks without modification.\u003c\/p\u003e\n\u003cp\u003eThis bit is used in screw machine shops, CNC drilling operations, sheet metal work, and general metalworking where a stub-length tool is preferred over a jobber-length bit. The Size 37 wire gauge designation corresponds to a decimal diameter of 0.1040 inches, placing it in the 0.1000 to 0.1500 inch size range. It is appropriate for use in drill presses, turret lathes, CNC machining centers, and handheld drill motors when rigidity and chip evacuation matter. The right-hand cutting direction is standard for conventional clockwise-rotating spindles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material with TiN coating for improved hardness and wear resistance in ferrous metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces entry thrust and eliminates pilot hole requirement\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 1-13\/16 inches OAL provides superior rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.1040 inches diameter fits standard drill chucks directly\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with parallel web configuration promotes consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty grade construction rated for demanding production drilling environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for Size 37 wire gauge screw machine length drill bits used in standard drill chucks accepting a 0.1040-inch straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tool-and-die professional. Secure the shank fully in the drill chuck and verify runout before operation. Always power down and lock out the spindle before changing tooling. Do not exceed the rated speed range for the workpiece material and bit diameter, and use appropriate cutting fluid when drilling hard ferrous alloys to maximize tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 37\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1040 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: TiN (Titanium Nitride)\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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13\/16 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: 0.1040 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.1000 to 0.1500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 66692138\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739681784114,"sku":"66692138","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a593d6d910bc97767212dbd9daa4010.jpg?v=1788817735","url":"https:\/\/voomisupply.com\/products\/hertel-66692138-screw-machine-drill-bit-size-37-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
