Built from high speed steel with a coated finish, it carries a 118-degree standard point angle and a web-thinned, tapered web configuration for improved penetration and chip clearance. The bit measures 21\/64 inch (0.3281 inches) in diameter with an overall length of 6.5 inches and a spiral flute length of 4.125 inches. The straight shank and right-hand cut design make it compatible with standard drill chucks. This is a Series 120 drill bit suited for machinists, maintenance technicians, and fabricators working in metal fabrication and mechanical trades.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for drilling into alloy steel, carbon steel, and cast iron in both shop and field environments. The taper length body provides extra reach compared to jobber-length bits, making it practical for deeper holes or applications where standard-length bits fall short. It is a single-piece, non-coolant-through design suitable for conventional drill press and hand-drill setups running standard cutting fluids or dry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e21\/64 inch (0.3281 inches) diameter with diameter tolerance of +0.0000 to -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for easier entry\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for alloy steel, carbon steel, and cast iron\u003c\/li\u003e\n  \u003cli\u003eTaper length body — 6.5 inches overall, 4.125-inch flute — for deeper reach than jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute, straight shank, no threaded shank — fits standard chucks\u003c\/li\u003e\n  \u003cli\u003eCoated finish for improved wear resistance on general-purpose applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose taper length drill bit for use in alloy steel, carbon steel, and cast iron.

Secure the shank fully in the chuck before operation and verify the workpiece is clamped or fixtured. Apply an appropriate cutting fluid when drilling steel or cast iron to extend tool life and maintain hole tolerance. Inspect the cutting edges for wear or chipping before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 21\/64 inch (0.3281 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3281 inches (8.33 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.375 inches (60.32 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\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\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 120\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1132 pounds\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: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 49721\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51728831152434,"sku":"49721","price":26.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6bdecf979c50a72364030dc4c4e00bb3.jpg?v=1788696549","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-49721-taper-length-drill-bit-21-64-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
