The 135-degree split point reduces walking at drill entry and lowers the thrust force required to start a hole without a center punch. An oxide and straw finish provides light lubricity and surface protection during dry or lightly lubricated drilling operations. With a straight cylindrical shank measuring 3\/64 inch (0.0469 decimal inch) in diameter and an overall length of 1.5 inches, the bit fits standard keyless and keyed drill chucks in handheld and bench-mounted applications. It carries a two-flute regular spiral configuration with a web-thinned, tapered web for improved chip evacuation.\u003c\/p\u003e\n\u003cp\u003eThis jobber drill is suited for general-purpose drilling in steel, cast iron, non-ferrous metals, and similar materials as indicated by the P, M, K, N, and S workpiece material codes. Its compact 1.5-inch overall length and 5\/8-inch flute length make it appropriate for close-quarter or shallow-hole applications. Electricians, HVAC technicians, plumbers, and general service trades commonly use small-diameter jobber bits like this one when installing hardware, mounting brackets, or routing components through sheet metal and structural members. The 3\/64-inch diameter targets fine fastener pilot holes and precision layout work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction provides elevated heat and wear resistance compared to standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces drill walking and lowers required feed pressure at entry\u003c\/li\u003e\n  \u003cli\u003eOxide and straw coating adds surface lubricity and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web improves chip flow and reduces heat buildup in the flutes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, regular spiral flute geometry for conventional drilling operations\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards and conforms to DIN 338 specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with standard 3-jaw keyless and keyed drill chucks accepting straight cylindrical shanks.

When drilling steel with small-diameter bits, use appropriate cutting fluid or cutting oil to extend tool life and reduce heat. Avoid excessive feed pressure on 3\/64-inch diameter bits, as the small cross-section is susceptible to breakage under lateral load. Ensure the workpiece is clamped or otherwise secured before drilling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/64 inch (0.0469 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 1.20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide and Straw (Bronze)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5\/8 inch (0.625 inches \/ 16.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches (38.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/64 inch (0.0469 inches \/ 1.2 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.8662 inches (22 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.6299 inches\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (Material Codes: P, M, K, N, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2ACO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI, DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePerformance Grade\u003c\/strong\u003e: Heavy Duty General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5999625\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51691574821170,"sku":"5999625","price":63.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/758de141a9fc20af5d344d75acdd3f69_dd42e121-0a9d-4607-a97e-bbe8e337ecda.jpg?v=1788287205","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999625-cobalt-jobber-drill-3-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
