Built to Series 229 specifications, it carries a No. 21 wire size designation with a decimal diameter of 0.1590 inches and an overall length of 2.5 inches. The 150-degree split point reduces entry force and walking on initiation, while the parabolic flute geometry promotes efficient chip evacuation. The bright uncoated finish is well suited for non-ferrous applications where coating adhesion or heat buildup is not a primary concern. Licensed HVAC techs, machinists, and metalworking tradespeople install this bit in standard drill chucks and CNC toolholders alike.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in non-ferrous metal applications, including aluminum, copper, brass, and similar materials designated under primary workpiece material code N and O. The straight-cylindrical shank at 0.1590 inches diameter fits standard keyless and keyed drill chucks without adapters. The 5xD flute-to-diameter ratio and a maximum drilling depth of 1.03125 inches make it practical for through-hole and blind-hole work in light plate and sheet stock. It is sold and packaged individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e150-degree standard point angle reduces thrust and minimizes drill walk on entry\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry with web thinning for improved chip flow and reduced cutting resistance\u003c\/li\u003e\n\u003cli\u003eThree-flute design increases feed rate capability compared to standard two-flute geometry\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish optimized for non-ferrous metal cutting\u003c\/li\u003e\n\u003cli\u003eMeets DIN 6537 L standards and manufactured under ISO 9001:2015 certified processes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling option for applications requiring a No. 21 wire size, 0.1590-inch diameter solid carbide jobber drill bit with a straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit should be installed and operated by qualified machinists or tradespeople familiar with drilling feeds, speeds, and workholding for carbide tooling. Ensure the drill chuck or collet is clean and properly tightened before operation to prevent runout that can chip carbide. Do not use in ferrous materials outside the specified primary workpiece material range, as this may cause premature tool failure. Eye protection and appropriate workpiece clamping are required during use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 21\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1590 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 150 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1590 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.03125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0190 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: 0.0002 to 0.0006 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered with Web Thinning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\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: 229\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 6537 L; ISO 9001:2015 Certified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: M.A. FORD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 22915900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51743276663090,"sku":"22915900","price":89.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a35655293648f6a60910d3738cafd1b_428eebd2-b2d4-4b54-9366-9398cf53bfcc.jpg?v=1788844920","url":"https:\/\/voomisupply.com\/products\/m-a-ford-22915900-carbide-jobber-drill-bit-no-21","provider":"Voomi Supply","version":"1.0","type":"link"}
