Sized at 7.5 mm (0.2953 inches) in diameter with a 140-degree split-point geometry, it delivers fast penetration and accurate hole entry with minimal walking. The AlTiN (aluminum titanium nitride) coating increases surface hardness and heat resistance, extending tool life in abrasive and high-temperature cutting environments. Right-hand cutting direction and coolant-through capability make this bit well suited to CNC machining centers and production drilling applications where chip evacuation and heat control are critical. Machinists and tool-and-die professionals are the primary users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for use in ferrous metals, stainless steel, cast iron, titanium, and other hard-to-machine alloys where a high-performance carbide tool is required. Its 46.9 mm flute length provides adequate depth capacity for most jobber-length drilling tasks. The 8.0 mm shank diameter seats securely in standard drill chucks and collet systems. It is appropriate for horizontal and vertical machining centers, CNC lathes with live tooling, and dedicated drilling machines operating under coolant.\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 improves heat resistance and extends cutting life in abrasive alloys\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust force and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design channels cutting fluid directly to the cutting edge for heat control and chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with standard jobber-length proportions for broad machine compatibility\u003c\/li\u003e\n  \u003cli\u003e8.0 mm shank diameter fits common collet and chuck toolholding 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, lathes with live tooling, and drilling machines equipped with coolant-through toolholding in the 7.00 mm to 8.00 mm drill size range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists familiar with CNC toolholding practices. Ensure the machine spindle is fully stopped and the tool is properly seated and torqued in the collet or chuck before initiating a cut. Verify coolant-through pressure is set to machine and toolholder specifications before use. Inspect the cutting edges for chipping or wear before each setup, as carbide tools can fail without visible warning if run outside recommended parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.5 mm (0.2953 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 96.0 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 46.9 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.0 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 77712412\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728872440114,"sku":"77712412","price":172.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e04b94c73a872671913fa2cfdf93016.jpg?v=1788697211","url":"https:\/\/voomisupply.com\/products\/accupro-77712412-carbide-jobber-drill-bit-7-5-mm-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
