Built from solid carbide, it delivers the rigidity and wear resistance required for drilling hardened steels, cast iron, stainless steel, and similar tough alloys. The WD1 coating reduces friction and extends tool life in high-cycle production environments. At 3.9 mm in diameter with a 120-degree drill point angle and a standard point geometry, this bit produces accurate, clean entry holes. It is sized for use in CNC machining centers, drill presses, and handheld pneumatic or electric tools with compatible collets or chucks.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for metalworking and machining applications in manufacturing, fabrication, and maintenance-repair-operations (MRO) environments. The 5xD flute-to-diameter ratio and 22 mm flute length make it appropriate for short-to-medium depth holes typical in sheet metal, structural components, and precision-machined parts. The straight-cylindrical shank with a 4.0 mm diameter seats securely in standard ER collet chucks and keyless drill chucks. Right-hand spiral flutes evacuate chips efficiently during operation, reducing heat buildup and recutting.\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\u003eWD1 coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003e120-degree drill point angle for accurate, centered starts on standard point applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral fluting for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard ER collets and drill chucks\u003c\/li\u003e\n\u003cli\u003e5xD flute ratio suited for short-to-medium depth drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style jobber length drill bit for use in CNC machining centers, drill presses, and rotary tools accepting a 4.0 mm straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified machinists or tooling technicians familiar with cutting tool setup. Secure the shank fully in the collet or chuck before use and verify runout is within acceptable limits for the application. Always operate within the recommended speed and feed range for solid carbide tooling in the workpiece material. Do not use this bit in hand drilling applications where axial control cannot be maintained, as carbide is brittle and susceptible to breakage under side-loading or impact.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.9 mm (0.1535 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 52.0 mm (2.047 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 22.0 mm (0.866 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.0 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: 120 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: WD1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 3.0 mm - 4.0 mm (0.1500 - 0.2000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3318390\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736622498098,"sku":"3318390","price":176.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/33f74288be2c227e07c778bafc8d84e0_51c84e60-dd12-4b02-8769-073dbf23954d.jpg?v=1788779010","url":"https:\/\/voomisupply.com\/products\/osg-3318390-carbide-jobber-drill-bit-3-9-mm-wd1","provider":"Voomi Supply","version":"1.0","type":"link"}
