Built with a 140-degree split point and AlTiN (aluminum titanium nitride) coating, this bit delivers fast penetration, reduced heat buildup, and extended tool life compared to uncoated or HSS alternatives. The web-thinned, tapered web design reduces thrust requirements at the start of each cut. At 0.3750 inches in diameter with an overall length of 110 millimeters, it covers a broad range of production drilling tasks. Machinists, toolroom technicians, and CNC operators working in aerospace, die and mold, and general metalworking applications are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill is suited for drilling steel, stainless steel, cast iron, and other ferrous and non-ferrous materials where coating performance and carbide rigidity are required. The straight cylindrical shank with a 10-millimeter shank diameter seats directly in standard drill chucks and collet systems. With a 5xD flute-to-diameter ratio and a 59.50-millimeter flute length, it supports drilling depths up to 1.875 inches in a single pass. Coolant-through capability makes it appropriate for high-speed CNC machining centers where internal coolant delivery is available.\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 reduces friction and extends tool life at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e140-degree split point with web thinning for reduced thrust and self-centering entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design compatible with CNC machines equipped with internal coolant delivery\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of -0.0005 to 0.0000 inches for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and drill presses accepting a straight cylindrical shank with a 10-millimeter shank diameter.

Secure the shank fully in the toolholder to the recommended grip depth before operation — insufficient shank engagement can cause tool pullout or breakage. Solid carbide is brittle; avoid interrupted cuts, side loads, or manual drilling applications where flex or shock loads are likely. Always verify spindle runout is within acceptable limits before running carbide tooling at high RPM.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3750 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 110 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 59.50 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.875 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\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003ePoint Type\u003c\/strong\u003e: Standard, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\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\u003eWeight\u003c\/strong\u003e: 0.11 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: 77712271\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748606968114,"sku":"77712271","price":261.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd7217cbc3346c71d044ab78ecd27c35.jpg?v=1788895647","url":"https:\/\/voomisupply.com\/products\/accupro-77712271-solid-carbide-jobber-drill-3-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
