Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction compared to uncoated HSS tooling. The 135-degree split point geometry promotes self-centering, reduces walking on entry, and decreases the thrust force required at the spindle. At a compact 1-11\/16 inches overall length, this stub-length format is well-suited for drill presses, CNC machining centers, and turret lathes where rigidity and minimal overhang matter. Machinists and tool-and-die professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis bit is sized at wire gauge No. 52, with a decimal equivalent of 0.0635 inches. Screw machine length bits are commonly specified in production drilling, tapping prep work, and short-hole applications where deflection control is critical. The straight-cylindrical shank fits standard drill chucks and collet holders across bench drill presses and CNC turning or milling equipment. Right-hand cutting direction is standard for conventional clockwise-spindle machines. The flute length is 11\/16 inches, keeping the cutting zone short and stiff for accurate hole location in close-tolerance work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge No. 52 size — 0.0635 inch decimal equivalent for precision hole sizing\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces walking and lowers entry thrust requirements\u003c\/li\u003e\n  \u003cli\u003eTiN coating extends tool life and improves chip evacuation versus bare HSS\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel web construction reduces cutting resistance in harder materials\u003c\/li\u003e\n  \u003cli\u003eStub screw machine length (1-11\/16 inches OAL) maximizes rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with straight-cylindrical shank for broad chuck and collet compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks and collet systems accepting a 0.0635-inch straight-cylindrical shank, compatible with drill presses, CNC machining centers, and turret lathes running right-hand (clockwise) spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove drill bits only with the spindle fully stopped and the machine powered down or e-stopped. Secure the shank fully within the chuck jaws or collet to the recommended grip depth — insufficient engagement increases runout and risks bit breakage at this small diameter. Cutting fluid or coolant is recommended when drilling ferrous metals, even though this bit does not feature through-coolant capability. Inspect the cutting edges and TiN coating before each use; chipped or worn edges on small-diameter bits increase the risk of breakage and out-of-tolerance holes.\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: No. 52\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0635 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0635 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: 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: 0.2 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: 02387454\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730142921010,"sku":"02387454","price":56.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eaf1639e940b86ba7d06faf9a1eeced4.jpg?v=1788712495","url":"https:\/\/voomisupply.com\/products\/hertel-02387454-drill-bit-size-52-tin-hss-135-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
