Sized at wire gauge No. 22 (0.1570 inches decimal equivalent), it features a 135-degree split point for fast, self-centering starts with reduced thrust. The titanium nitride (TiN) coating extends tool life by increasing surface hardness and reducing friction. At 2.125 inches overall length, this stub-style bit fits compact drilling setups, drill presses, and CNC turret applications common in production and fabrication environments. A web-thinned construction improves chip evacuation during through-hole drilling.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production drilling in metals, plastics, and similar materials where a screw machine length format is preferred over jobber-length tooling. The straight-cylindrical shank accommodates standard three-jaw chucks and collet holders. The regular spiral flute and parallel web configuration make it appropriate for moderate-feed drilling in both manual and automated setups. Machinists, toolroom technicians, and fabricators working in small-hole, high-volume applications will find this format reduces deflection and breakage compared to longer drill styles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge No. 22 size — 0.1570 inch decimal equivalent diameter\u003c\/li\u003e\n\u003cli\u003e135-degree split point for self-centering entry and reduced thrust load\u003c\/li\u003e\n\u003cli\u003eTiN coating increases surface hardness and extends cutting life\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel web construction promotes chip clearance\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length at 2.125 inches OAL reduces deflection in tight setups\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, regular spiral flute with straight-cylindrical shank\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-use screw machine length drill bit compatible with standard three-jaw chucks and collet holders accepting a 0.1570-inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should follow standard machine shop practice for rotating cutting tools. Secure the shank fully in the chuck or collet before operation and verify runout before production use. Always wear appropriate eye protection and follow the machine manufacturer's recommended feed and speed guidelines for the workpiece material. Inspect the cutting edges and TiN coating for wear or chipping before each use; replace when performance degrades to avoid workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 22\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1570 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1570 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.1500 to 0.2000 inches\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 2387397\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744932397362,"sku":"2387397","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f99dfb6f89853ed8a0dccf96adeb5609.jpg?v=1788862399","url":"https:\/\/voomisupply.com\/products\/hertel-2387397-screw-machine-drill-bit-size-22-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
