Built from solid carbide and coated with TiAlN, it handles the heat and abrasion common when drilling stainless steels and other hard alloys. The bit features a 140-degree web-thinned point that reduces entry force and improves centering accuracy. At 3.9370 inches overall length with a 1.6730-inch flute length, this is a stub-style drill optimized for rigidity in short-reach applications. Coolant-through capability supports high-speed, deep-hole operations where chip evacuation and thermal management are critical. Licensed HVAC techs, machinists, and metalworking professionals specify this type of tooling for production environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for primary use in stainless steels, making it a practical choice for fabrication, maintenance, and repair work where corrosion-resistant alloys are common. The straight cylindrical shank fits standard drill chucks and collet systems without modification. The 3xD flute-to-diameter ratio suits screw machine setups and CNC drilling operations where compact tooling is preferred. The right-hand cutting direction is standard for conventional spindle rotation.\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\u003eTiAlN coating extends tool life in high-temperature cutting environments\u003c\/li\u003e\n\u003cli\u003e140-degree web-thinned point reduces thrust and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip evacuation and heat control during deep drilling\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank at 0.3438 inches diameter fits standard chucks and collets\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry promotes consistent chip flow in stainless and similar alloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance screw machine length drill bit for use in stainless steels, within the ACCUPRO ASSC140-TA-CL series, with a decimal inch size range of 0.3000 to 0.3500 inches.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or trades professionals familiar with CNC or manual drilling equipment. Ensure the spindle and chuck are fully powered down and locked out before loading or removing tooling. Verify that coolant lines are properly connected and flowing before running coolant-through tooling at rated speeds. Follow machine manufacturer guidelines and applicable ISO specifications for tooling setup and safe operating parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: Q\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3320 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.9370 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.6730 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3438 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ASSC140-TA-CL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 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: 4500375\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734661595442,"sku":"4500375","price":171.17,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3f875106800dcb322f5eaddc0b0ee73.jpg?v=1788764535","url":"https:\/\/voomisupply.com\/products\/accupro-4500375-drill-bit-letter-q-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
