Built from solid carbide and coated with AlTiN (aluminum titanium nitride), this bit delivers high heat resistance and extended tool life in abrasive and hard-material environments. The drill features a 140-degree split point angle for accurate starting without center punching, a 0.6250-inch (5\/8-inch) diameter, and a spiral flute design with a 7xD flute-to-diameter ratio. Coolant-through capability allows internal coolant delivery to the cutting zone, reducing heat buildup and chip evacuation issues during deep drilling operations. Licensed machinists and tool-and-die professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis taper length drill bit is suited for ferrous and non-ferrous metals, stainless steels, cast iron, and other difficult-to-machine materials in CNC machining centers and manual drill presses. The straight shank with a 16.00 mm shank diameter fits standard ER collet chucks and keyless chucks commonly used in production and job-shop environments. The extended 5.469-inch flute length supports deeper reach than jobber-length bits of the same diameter, making it appropriate for through-holes and deeper blind holes in structural and tooling components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides high-temperature oxidation resistance and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle enables self-centering starts and reduces thrust in interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers fluid directly to the cutting tip for heat control and chip clearing\u003c\/li\u003e\n  \u003cli\u003e7xD flute length-to-diameter ratio supports deep-hole drilling beyond standard jobber-length reach\u003c\/li\u003e\n  \u003cli\u003eStraight shank at 16.00 mm diameter is compatible with standard collet and keyless chuck tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a taper length, straight-shank drill bit for use in CNC machining centers, drill presses, and similar machine tool setups that accept 16.00 mm straight-shank tooling with collet or keyless chuck holding systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer guidelines for chuck torque and runout tolerance. Ensure the machine spindle is fully stopped and the tooling circuit is de-energized or locked out before inserting or removing the bit. Verify shank seating depth and chuck engagement before initiating a cut. When using the coolant-through feature, confirm that coolant pressure and flow rate are within the range recommended for the machine spindle and workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.6250 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.469 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.469 inches (7-31\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 16.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 7xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.21 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 62760798\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750066585906,"sku":"62760798","price":777.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a54b4bd1b876e18c8a425ca77615524_26007498-422d-4fe8-9de6-cdef82059991.jpg?v=1788913474","url":"https:\/\/voomisupply.com\/products\/accupro-62760798-taper-length-drill-bit-5-8-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
