Manufactured from solid carbide and finished with an AlTiN (aluminum titanium nitride) coating, this bit delivers excellent heat resistance and extended tool life at high cutting speeds. It features a 140-degree split point for accurate positioning and reduced thrust, a web-thinned tapered web for improved chip evacuation, and a two-flute regular spiral design. With an overall length of 5.197 inches and a 27\/64-inch (0.4219 inch) diameter, it suits a wide range of precision drilling operations. Installed by machinists, tool-and-die workers, and industrial maintenance technicians.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling ferrous metals, stainless steels, cast iron, and other hard materials where solid carbide tooling outperforms high-speed steel. The AlTiN coating adds oxidation resistance and allows dry or minimal-lubrication cutting in high-heat applications. The straight-cylindrical shank with a diameter of 12 millimeters seats securely in standard drill chucks and collet holders. With a maximum drilling depth of 2.110 inches and a flute length of 67 millimeters, it handles through-hole and blind-hole work at production volumes. Coolant-through capability supports chip clearing in deep-hole operations.\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 heat and oxidation resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle reduces entry thrust and improves positional accuracy\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports deep-hole drilling and chip clearing\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, two-flute regular spiral for consistent cutting action\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length solid carbide drill bit compatible with standard drill chucks and collet tool holders accepting a straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is intended for use in CNC machining centers, drill presses, and manual machine tools by qualified machinists and maintenance technicians. Secure the straight-cylindrical shank fully in a matched collet or chuck before operation and verify runout before drilling. Inspect the cutting edges for chipping or wear before each use, as solid carbide is brittle and susceptible to fracture under side-load or impact conditions. Follow machine manufacturer guidelines for spindle speed and feed rate appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 27\/64 inch (0.4219 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.197 inches (132 millimeters)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 67 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.110 inches\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: Regular Spiral\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\u003eShank Diameter\u003c\/strong\u003e: 12 millimeters\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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\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: 77712222\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750657524018,"sku":"77712222","price":346.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5cb7a60369242f53fe6b9131878d3745.jpg?v=1788917935","url":"https:\/\/voomisupply.com\/products\/accupro-77712222-jobber-drill-bit-27-64-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
