It measures 12 mm in diameter with an overall length of 132 mm and a flute length of 75 mm. The 140-degree split point geometry reduces walking and allows aggressive entry without a center punch. An AlTiN coating improves heat resistance and extends tool life in hard, abrasive, and high-temperature alloys. Coolant-through capability supports chip evacuation and thermal control during deep-hole operations. This bit suits machinists, tool-and-die shops, and precision fabrication environments where dimensional accuracy and tool longevity are priorities.\u003c\/p\u003e\u003cp\u003eThis drill bit is used in CNC machining centers, drill presses, and manual machines where consistent hole quality in tough materials is required. The straight-cylindrical shank fits standard ER collet chucks, drill chucks, and hydraulic toolholders across common spindle configurations. It is well-suited for drilling stainless steel, hardened alloys, titanium, cast iron, and high-strength steels. The 5xD flute-to-diameter ratio supports drilling depths up to approximately 2.362 inches without pausing to clear chips when coolant-through is active.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\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 point angle reduces entry force and minimizes workpiece deformation\u003c\/li\u003e\n\u003cli\u003eCoolant-through design promotes chip evacuation and cooling at the cutting edge\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces thrust requirements and improves centering\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of -0.0005 to 0.0000 inches for consistent, close-tolerance holes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance replacement or direct-use solid carbide jobber drill for CNC and manual drilling applications requiring a 12 mm straight-cylindrical shank tool with coolant-through capability.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle and toolholder are clean and free of debris before seating the shank. Verify that the machine's coolant-through system pressure is appropriate for the material and depth being drilled. Do not exceed the recommended drilling depth for the flute length to avoid chip packing and tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 12 mm (0.4724 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 132 mm (approximately 5.197 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 75 mm (approximately 2.953 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12 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: 2.362 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 by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePerformance 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: 77712065\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730773606706,"sku":"77712065","price":318.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e968eda08e831edc2c92f3c7c3582333.jpg?v=1788722627","url":"https:\/\/voomisupply.com\/products\/accupro-77712065-carbide-jobber-drill-bit-12-mm-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
