Built from high-speed steel with a titanium nitride coating, this bit runs at higher surface speeds and resists wear longer than uncoated HSS tooling. The 135-degree split point geometry reduces thrust and enables the bit to self-center without a pilot hole. At 1.375 inches overall length with a 0.5-inch flute length, this stub-length format minimizes deflection and is well suited to CNC machine tools, drill presses, and turret lathes in production environments.\u003c\/p\u003e\n\u003cp\u003eThis bit is sized at wire gauge number 56, equivalent to 0.0465 inch decimal diameter, placing it in the small-diameter precision range commonly used in aerospace, electronics assembly, and tight-tolerance machining work. The straight cylindrical shank fits standard collets and drill chucks without adapters. The regular spiral, two-flute configuration with a parallel web and web-thinning promotes chip evacuation in through-hole and blind-hole applications. Machinists, toolmakers, and CNC operators in job shops and production facilities are the primary installers of this tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 56 at 0.0465 inch decimal diameter for precision small-hole work\u003c\/li\u003e\n  \u003cli\u003eTiN coating extends tool life and allows higher cutting speeds versus bare HSS\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces entry thrust and eliminates the need for a center punch\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length of 1.375 inches overall improves rigidity and reduces deflection\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web improves chip flow and reduces heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, regular spiral flute compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks and collet holders accepting a 0.0465-inch straight cylindrical shank, as found on drill presses, CNC machining centers, and turret lathes performing small-diameter precision drilling operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMachine tool operators should ensure the workpiece is securely fixtured and the spindle speed is set to a value appropriate for the workpiece material and bit diameter before beginning. Confirm the drill chuck or collet is clean and undamaged before seating the shank to prevent runout. At small diameters such as this, excessive feed pressure is the leading cause of bit breakage; allow the cutting geometry to do the work. Follow shop safety standards and wear appropriate eye protection during all drilling operations.\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: 56\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0465 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0465 inches\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\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular 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, Web-Thinned\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 02387496\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732660879666,"sku":"02387496","price":60.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53d0d4435b5245027ebc9a94e241385a.jpg?v=1788745452","url":"https:\/\/voomisupply.com\/products\/hertel-02387496-screw-machine-drill-bit-size-56-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
