Built to wire gauge size 43, this bit measures 0.0890 inches in diameter with a 1.75-inch overall length and a 0.75-inch flute length. The 135-degree split point reduces walking on entry and requires less thrust than a standard 118-degree point. Cobalt construction provides elevated heat resistance and edge retention under demanding production conditions. This is a heavy-duty bit suited for machine shops, maintenance environments, and production drilling applications.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in screw machines, drill presses, and hand-held power drills where short, rigid tooling is preferred over jobber-length bits. The reduced length increases stiffness and minimizes deflection in small-diameter drilling, making it well suited for close-tolerance work in metal fabrication and repair. The right-hand cutting direction is standard for conventional drilling equipment. Each package contains one bit, sold in minimum order quantities of 12 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 43 with 0.0890-inch decimal diameter for precise small-hole drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces drill walk and improves entry accuracy on curved or angled surfaces\u003c\/li\u003e\n\u003cli\u003eCobalt tool material with straw finish provides superior heat and wear resistance versus standard high-speed steel\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length increases rigidity and reduces deflection in tight setups\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral design promotes efficient chip evacuation in metals\u003c\/li\u003e\n\u003cli\u003eHeavy-duty grade construction rated for production and high-cycle drilling environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard straight-shank screw machine length drill bit compatible with conventional drill chucks accepting shanks in the 0.0890-inch diameter range, including bench drill presses, CNC turret machines, and hand-held power drills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by machinists or qualified trade personnel familiar with small-diameter tooling. Secure the bit fully in the chuck and verify zero runout before beginning a cut, as small-diameter cobalt bits are brittle and susceptible to breakage from lateral loading. Always reduce spindle speed and increase feed pressure gradually when drilling hardened or work-hardened materials. Inspect the cutting edges before each use and replace the bit at the first sign of chipping or heat discoloration.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 43\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0890 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 01378439\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694731821362,"sku":"01378439","price":39.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e17ffa1aca813893891f9b5969e3038.jpg?v=1788327784","url":"https:\/\/voomisupply.com\/products\/value-collection-01378439-size-43-cobalt-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
