Built from C2-grade carbide with a bright finish, it delivers consistent performance in applications where tool rigidity and dimensional accuracy are critical. The 140-degree notched point and web-thinned geometry reduce entry force and improve chip evacuation. With a diameter of 0.1570 inches and a tight tolerance of +0.0000 to -0.0005 inches, this bit holds size in demanding production environments. Two right-hand cutting flutes provide clean, controlled material removal in ferrous and exotic alloy workpieces.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for machining operations involving chrome alloy, heat-treated alloy, nickel alloy, stainless steel, steel, and titanium alloy. It is a No. 22 wire gauge size, making it a standard selection for close-tolerance hole applications in aerospace, industrial, and precision fabrication settings. Machinists and tool and die technicians typically specify this bit for CNC drilling centers, drill presses, and manual machining operations where carbide rigidity outperforms high-speed steel in hardened or abrasive materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid C2-grade carbide construction for high hardness and wear resistance in tough alloys\u003c\/li\u003e\n\u003cli\u003e140-degree notched point reduces thrust load and improves centering on entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned geometry promotes chip flow and lowers cutting resistance\u003c\/li\u003e\n\u003cli\u003eBright finish with no coating — suitable for dry cutting or light lubrication applications\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance held to +0.0000 to -0.0005 inches for precision fit requirements\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, two-flute straight design for maximum rigidity in short-hole drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard straight-flute carbide drill bit for use in CNC machining centers, drill presses, and precision drilling fixtures requiring a 0.1570-inch diameter No. 22 wire gauge hole.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists following standard shop safety procedures. Secure the shank firmly in a compatible chuck or collet rated for the spindle speed and feed rate appropriate to the workpiece material. Do not exceed recommended cutting parameters for carbide tooling, as carbide is brittle and susceptible to breakage under shock loading or excessive lateral force. Inspect the cutting edges before each use and replace if chipping or wear is detected.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Type\u003c\/strong\u003e: Straight-Flute\u003c\/li\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 Diameter\u003c\/strong\u003e: 0.1570 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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide, C2 Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright (uncoated)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Notched\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Chrome Alloy, Heat-Treated Alloy, Nickel Alloy, Stainless Steel, Steel, Titanium Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 83246454\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748096049458,"sku":"83246454","price":38.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47dc9e7d6cd87b3e54a6bc1da4971605.jpg?v=1788889005","url":"https:\/\/voomisupply.com\/products\/hertel-83246454-carbide-drill-bit-0-1570-in-no-22","provider":"Voomi Supply","version":"1.0","type":"link"}
