Built to wire gauge size 44 (0.0860 inches decimal), it features a 135-degree split point that starts on contact and reduces walking without a center punch. The web-thinned, parallel web construction improves chip evacuation and lowers thrust requirements. At 1.75 inches overall length, the stub-length format suits close-quarters drilling applications. This bit is suited for use in drill presses, CNC machines, and hand-held power drills by machinists, maintenance technicians, and industrial tradespeople.\u003c\/p\u003e\n\u003cp\u003eScrew machine length drill bits are commonly used in production drilling, sheet metal work, and tight-clearance applications where a jobber-length bit would flex or chatter. The short flute length of 0.75 inches provides added rigidity. The straw finish indicates heat-treated cobalt steel, making this bit appropriate for stainless steel, cast iron, high-nickel alloys, and other work-hardening materials encountered in industrial maintenance and fabrication environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for drilling stainless steel, cast iron, and work-hardening alloys\u003c\/li\u003e\n  \u003cli\u003e135-degree split point starts on contact and eliminates center-punch requirement in most setups\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web reduces axial thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eStub screw machine length (1.75 inches OAL) adds rigidity and suits close-clearance drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute geometry compatible with standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard 3-jaw chucks and collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard supply for screw machine length drill bit applications requiring wire gauge size 44 with a straight cylindrical shank.

Secure the shank fully in the chuck and verify concentricity before running at speed. Cobalt bits tolerate dry drilling but perform best with appropriate cutting fluid on stainless or high-alloy workpieces. Do not use excessive feed pressure on thin-gauge material, as small-diameter bits at this size range are susceptible to breakage under side-load or deflection.\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: 44\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0860 inches\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 Point\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: Straw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eSeries\u003c\/strong\u003e: HSCO135\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 74130964\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743312052530,"sku":"74130964","price":40.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d0da23a7b923310b146e01ca27dc420.jpg?v=1788845479","url":"https:\/\/voomisupply.com\/products\/hertel-74130964-cobalt-screw-machine-drill-bit-size-44","provider":"Voomi Supply","version":"1.0","type":"link"}
