Built to Series HSCO135 standards, this bit features a 135-degree split point that reduces walking and allows fast penetration without a center punch. The web-thinned, parallel-web construction minimizes thrust during entry. At 1.75 inches overall length with a 0.75-inch flute length, this stub-length geometry provides rigidity and resistance to deflection in short-reach applications. The bright straw finish indicates cobalt steel composition without an added coating. Machinists, tool-and-die workers, and maintenance technicians reach for this style when drilling stainless steel, high-alloy steel, and other work-hardening materials.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for CNC machining centers, drill presses, and hand-held power tools where a stub-length bit is preferred for stiffness and control. The straight cylindrical shank fits standard Jacobs-style chucks and collet holders. It is commonly used in metal fabrication shops, maintenance and repair operations, and production environments where wire-gauge hole sizing to 0.0820 inches is required. The right-hand spiral and regular flute geometry provide efficient chip evacuation in through-hole and blind-hole applications in metalworking settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction for heat and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates center-punch requirement on flat surfaces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web lowers cutting resistance at the chisel edge\u003c\/li\u003e\n  \u003cli\u003eStub screw machine length (1.75 inches OAL) delivers maximum rigidity and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet holders without modification\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with 2-flute regular spiral for reliable chip clearance in metalworking applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard wire-gauge screw machine length drill bit for use in any drill press, machining center, or power tool equipped with a chuck or collet accepting a straight cylindrical shank in the 0.0820-inch decimal-inch size range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank fully in the chuck or collet and verify runout before beginning a cut. Use cutting fluid or coolant appropriate for the workpiece material to extend tool life when drilling stainless or alloy steels. De-energize and lock out any machine before changing tooling per applicable OSHA lockout-tagout procedures. Inspect the cutting edges for chipping or wear before each use and replace the bit if edge integrity is compromised.\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: 45\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0820 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 High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw (Bright\/Uncoated)\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\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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  \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: 74130972\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51740783149362,"sku":"74130972","price":41.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f852c7e0c77b065775032a5fede7dff4.jpg?v=1788827406","url":"https:\/\/voomisupply.com\/products\/hertel-74130972-cobalt-screw-machine-drill-bit-size-45","provider":"Voomi Supply","version":"1.0","type":"link"}
