It measures 8 mm in diameter with an overall length of 75 mm and a flute length of 40 mm. The AlTiN (aluminum titanium nitride) coating improves heat resistance and extends tool life in demanding cutting conditions. The 140-degree notched point reduces thrust and improves self-centering on entry. This bit is used by machinists, tool-and-die workers, and maintenance professionals operating CNC machining centers, drill presses, and manual equipment in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for applications in ferrous metals, stainless steel, cast iron, and high-temperature alloys where standard high-speed steel tooling wears prematurely. The straight-cylindrical shank fits standard drill chucks and collet holders. With a 4xD flute-to-diameter ratio and a maximum drilling depth of 32 mm, it handles through-hole and blind-hole work in medium-thickness workpieces. The regular spiral and parallel web configuration provide consistent chip evacuation. It is sold individually and intended for professional machine-shop and industrial maintenance use.\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 for elevated heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e140-degree notched point reduces entry thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web for reduced cutting force and cleaner chip formation\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with 4xD ratio supports efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard chucks and collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-performance jobber-length drill bit for use in CNC machining centers, drill presses, and manual drilling equipment equipped with standard chuck or collet toolholding systems accepting an 8 mm straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank fully in the chuck or collet before operation and verify runout is within acceptable tolerance for the application. Use appropriate cutting fluid or coolant where the machine setup permits, particularly when drilling stainless steel or high-temperature alloys. Inspect the cutting edge for chipping before each use, as carbide tooling is brittle and sensitive to side loads or interrupted cuts. Follow the machine manufacturer and applicable shop-safety guidelines when setting spindle speed and feed rate.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8 mm (0.3150 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 75 mm (2.953 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 40 mm (1.575 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 32 mm (1.260 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm\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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 4xD\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\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\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: 63310502\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744976142642,"sku":"63310502","price":103.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa88ec12364e812ad4f2c6440abc13a1.jpg?v=1788862863","url":"https:\/\/voomisupply.com\/products\/accupro-63310502-carbide-jobber-drill-bit-8mm-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
