Built with a 140-degree split point and spiral flute geometry, this bit reduces walking on entry and improves chip evacuation during the cut. The AlTiN (aluminum titanium nitride) finish extends tool life by increasing surface hardness and heat resistance at elevated cutting speeds. At 1\/16 inch in diameter, it is sized for small-hole applications requiring consistent dimensional accuracy. Right-hand cut configuration suits standard CNC and manual drilling setups. Through-coolant capability supports sustained performance in deeper hole applications.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in machine shops, manufacturing facilities, and precision fabrication environments. Its screw machine (stub) length profile makes it the right choice when working in confined spaces or on short-setup drill presses and machining centers. The straight shank provides broad compatibility with standard drill chucks and collet systems. Typical applications include small-diameter through-holes and blind holes in ferrous and non-ferrous materials where surface finish and hole accuracy are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in high-speed applications\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point reduces entry thrust and minimizes bit walking\u003c\/li\u003e\n  \u003cli\u003eAlTiN finish improves heat resistance and extends tool life at elevated RPMs\u003c\/li\u003e\n  \u003cli\u003eSpiral flute geometry promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design supports deeper hole drilling and thermal management\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with straight shank for compatibility with standard drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style screw machine drill bit suitable for use in standard drill chucks and collet holders accepting straight-shank bits in the 0.0000 to 0.1000 decimal inch size range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this bit should be performed by qualified machinists or tooling technicians familiar with CNC or manual drilling equipment. Ensure the spindle and workholding are fully stopped and locked out before changing tooling. Verify chuck or collet runout is within acceptable tolerance before use, as excessive runout on small-diameter carbide bits can cause premature breakage. Use appropriate cutting fluid or coolant flow rates consistent with the material being drilled and the machine tool manufacturer's recommendations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.94 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 59.99 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCut Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Style\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant\u003c\/strong\u003e: Through Coolant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize Range\u003c\/strong\u003e: 0.0000 to 0.1000 decimal inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: 61534459\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":52026819838258,"sku":"61534459","price":133.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c9b3c9d04bf57e82433a83f840812ff_22b633d2-bb7e-4b0e-91d6-09326abe4273.jpg?v=1790016650","url":"https:\/\/voomisupply.com\/products\/accupro-61534459-carbide-screw-machine-drill-bit-1-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
