Built from high-speed steel with an oxide finish, it delivers consistent performance in general-purpose production and maintenance drilling applications. The bit measures 1-3\/8 inches (1.3750 inches decimal) in diameter and features a 118-degree standard point angle with web thinning to reduce thrust and improve centering at the start of a cut. The 4MT (Morse Taper 4) shank seats directly into compatible taper-socket spindles on drill presses, lathes, and magnetic drilling machines. Overall weight is 8 pounds.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for machine shop, fabrication, and industrial maintenance environments where large-diameter holes must be drilled in a single pass or with minimal step drilling. The spiral flute design with a regular spiral type evacuates chips efficiently during deep-hole drilling. Right-hand cutting direction is standard for conventional spindle rotation. The bit does not support coolant-through delivery, so external flood or mist coolant should be applied at the cutting edge when drilling hard materials or running extended production cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-3\/8 inch diameter high-speed steel construction for general-purpose production drilling\u003c\/li\u003e\n  \u003cli\u003e4MT (Morse Taper 4) shank for direct mounting in taper-socket spindles without a chuck\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web thinning to reduce entry thrust and improve bit centering\u003c\/li\u003e\n  \u003cli\u003e17-inch spiral flute length supports deep-hole chip evacuation\u003c\/li\u003e\n  \u003cli\u003e24-inch overall length accommodates deep workpieces and extended-reach setups\u003c\/li\u003e\n  \u003cli\u003eOxide finish provides mild lubricity and corrosion resistance during storage and use\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, regular spiral, Series 502 designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any machine spindle, drill press quill, or lathe tailstock that accepts a 4MT (Morse Taper 4) socket.

Before mounting, clean the taper socket and the drill shank thoroughly to ensure full metal-to-metal contact and prevent fretting. Power down and lock out the machine before seating or removing the bit from the spindle. Apply appropriate external coolant at the cutting edge during operation, as this bit does not support coolant-through delivery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1-3\/8 inches (1.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Taper Designation\u003c\/strong\u003e: 4MT (Morse Taper 4)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 17 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 502\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241639\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 01665785\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709488398642,"sku":"01665785","price":418.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d950c094c6f51ca2b1a1372d17ccccbc.jpg?v=1788457082","url":"https:\/\/voomisupply.com\/products\/value-collection-01665785-taper-shank-drill-bit-1-3-8-in-4mt","provider":"Voomi Supply","version":"1.0","type":"link"}
