It carries a wire gauge size 53 designation, corresponding to a decimal diameter of 0.0595 inches, with an overall length of 1.625 inches and a flute length of 0.625 inches. The 135-degree split point reduces walking and requires no center punch before drilling. The two-flute regular spiral geometry promotes efficient chip evacuation in short-hole applications. This bit is used by machinists, tool-and-die technicians, and maintenance professionals who need reliable performance on small-diameter, precision work.\u003c\/p\u003e\n\u003cp\u003eThis screw machine length drill bit is suited for production and maintenance drilling applications where a shorter, more rigid tool profile is preferred over jobber-length bits. The reduced length improves stability and minimizes deflection when drilling small-diameter holes in ferrous metals, castings, and other hard materials. It fits standard drill chucks and CNC machining centers that accept straight cylindrical shanks. The cobalt construction maintains hardness at elevated cutting temperatures, making it appropriate for dry or minimally lubricated cuts in demanding shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction retains cutting edge hardness at elevated temperatures for drilling hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point self-centers on contact, eliminating the need for a center punch\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web reduces cutting resistance and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eScrew machine length profile provides added rigidity and reduced deflection compared to jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute geometry for standard drilling operations\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard three-jaw 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 or direct substitute for wire gauge size 53 screw machine length drill bits with a straight cylindrical shank.

Secure the shank firmly in the chuck or collet before operation and verify runout before beginning a cut. Always power down and lock out the machine before changing tooling. Avoid excessive feed pressure on small-diameter bits to prevent breakage, and allow chips to clear the flutes regularly during deep or interrupted cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 53\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0595 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\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: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.625 inches\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: 0.02 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: 74131053\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51740272197938,"sku":"74131053","price":48.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/754f562cde17f4ec89acb3ec0edecf78.jpg?v=1788823907","url":"https:\/\/voomisupply.com\/products\/hertel-74131053-cobalt-screw-machine-drill-bit-size-53","provider":"Voomi Supply","version":"1.0","type":"link"}
