The bit measures 0.625 inches in diameter with a 0.500-inch Weldon flat shank, allowing it to seat securely in compatible chucks without slipping under torque. The 118-degree standard point angle suits general-purpose applications across production and maintenance drilling. Overall length is 6 inches with a 3-inch spiral flute length, placing this in the standard jobber class for reach and chip evacuation. The bright, uncoated high speed steel construction is appropriate for moderate-speed drilling without coolant. Series R57.\u003c\/p\u003e\n\u003cp\u003eThis bit fits common drill press, mill, and hand-drill applications in industrial, mechanical, and maintenance environments. The reduced shank design allows a 5\/8-inch cutting diameter to run in a 1\/2-inch chuck, expanding the usable range of standard equipment without a chuck upgrade. Right-hand cut geometry is compatible with conventional rotating spindles. It is suited for ferrous metal fabrication, field maintenance, and general-purpose shop work where a Weldon shank is preferred for positive drive retention. No coolant system is required, making it practical for portable or bench-top setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-inch (0.6250 inch) cutting diameter with 1\/2-inch reduced Weldon flat shank for standard chuck compatibility\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry into ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e3-inch flute length provides up to 3 inches of drilling depth per pass\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with bright, uncoated finish for use without coolant\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix for consistent chip removal\u003c\/li\u003e\n  \u003cli\u003eThree flats on Weldon shank resist rotation and slippage under load\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 1\/2-inch chucks on drill presses, milling machines, and hand drills.

Confirm the chuck set screw or collet is tightened against the flats to prevent axial pullout. Verify spindle rotation is right-hand before engaging the workpiece. Follow applicable shop safety protocols 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\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3 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\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Required\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Aluminum, Cermet, Copper, Magnesium, Nickel, Synthetic, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R57\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6000021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51706769310002,"sku":"6000021","price":66.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/221e24691eddf263cc3c0bbb7104b0b2.jpg?v=1788436531","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000021-reduced-shank-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
