It measures 9 mm in diameter with a 140-degree split point and features an AlTiN (aluminum titanium nitride) coating for extended tool life at elevated cutting temperatures. The overall length is 110 mm with a 56.3 mm flute length. Coolant-through capability allows internal coolant delivery directly to the cutting zone, making it suitable for deep-hole and high-speed drilling operations on hard and abrasive materials. Licensed machinists and CNC operators are the primary installers and users of this tool.\u003c\/p\u003e\u003cp\u003eThis bit is suited for use in CNC machining centers, drill presses, and manual mills where precise, repeatable hole sizing is required. The 9 mm cutting diameter and straight-cylindrical shank at 10 mm diameter fit standard collet chucks and drill chucks configured for that shank size. Typical applications include drilling ferrous metals, stainless steels, cast iron, and high-temperature alloys. The web-thinned, tapered web configuration reduces thrust requirements and improves chip evacuation in production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard-material drilling\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides oxidation resistance and extends tool life in high-speed, dry, or minimum-quantity lubrication (MQL) cutting\u003c\/li\u003e\n\u003cli\u003e140-degree split point reduces walking and lowers entry thrust on hard workpieces\u003c\/li\u003e\n\u003cli\u003eCoolant-through design channels fluid directly to the cutting edge for deep-hole applications\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web improves chip flow and reduces heat buildup at the tip\u003c\/li\u003e\n\u003cli\u003eRegular spiral, 2-flute geometry suitable for a wide range of metalworking materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit solid carbide jobber drill for machining setups accepting a 10 mm straight-cylindrical shank in the 9 mm to 10 mm drill diameter size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with CNC or manual machine setup. Ensure the machine spindle and chuck are fully de-energized and at a complete stop before inserting or removing the bit. Verify collet or chuck runout is within acceptable tolerance before cutting, as excessive runout accelerates carbide wear and can cause premature breakage. Follow applicable workplace safety standards and machine manufacturer guidelines for speeds, feeds, and coolant pressure when using coolant-through tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9 mm (0.3543 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 110 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 56.3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.772 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 77712511\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746612150578,"sku":"77712511","price":225.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d64482e3921de4ee537529dbd2e55ae.jpg?v=1788871752","url":"https:\/\/voomisupply.com\/products\/accupro-77712511-carbide-jobber-drill-bit-9-mm-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
