Built with a carbide-tipped construction and a bright\/uncoated finish, this bit delivers clean, accurate holes in tough materials including Inconel, stainless steel, and carbon steel. The 3\/8 inch drill diameter holds a tight tolerance of plus 0.0005 to minus 0.0005 inches, ensuring precise bore sizing. At 10 inches overall length with a 6 inch flute length, this bit is suited for deep-reach applications where standard twist drills fall short. It is typically installed by machinists and tool-and-die professionals in CNC or manual deep-hole drilling setups.\u003c\/p\u003e\n\u003cp\u003eThis gun drill bit is designed for metalworking and multipurpose drilling operations, particularly in production environments requiring consistent hole depth and straightness in hard or high-temperature alloys. The through-coolant capability via a round coolant hole allows cutting fluid delivery directly to the tip, reducing heat buildup and chip evacuation issues during deep cuts. The 3\/4 inch shank diameter accepts standard gun drill holders and deep-hole drilling fixtures. Right-hand cutting direction is standard for conventional spindle rotation on most machining centers and dedicated gun drilling machines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide-tipped construction for cutting Inconel, stainless steel, and steel\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant support via round coolant hole for thermal management during deep cuts\u003c\/li\u003e\n  \u003cli\u003eTight drill diameter tolerance of plus 0.0005 to minus 0.0005 inches for accurate bore sizing\u003c\/li\u003e\n  \u003cli\u003e115-degree point angle with N-8 Nosegrind point type for controlled entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned geometry reduces cutting resistance and improves chip flow in deep holes\u003c\/li\u003e\n  \u003cli\u003eR-1 Low Land contour style minimizes friction along the bore wall\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in metalworking and multipurpose drilling applications involving Inconel, stainless steel, and steel.

Before mounting, verify spindle speed and feed rate recommendations for the target material and ensure the coolant system is primed and delivering fluid through the bit. Secure the shank fully in the holder to the rated drive length before engaging the spindle. Never exceed the depth-of-cut rating of the holder or machine setup, and inspect the cutting tip for wear or chipping before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.3150 inches declared)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Length\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth of Cut\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 115 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: N-8 Nosegrind\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Type\u003c\/strong\u003e: Single Flute Gun\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContour Style\u003c\/strong\u003e: R-1 Low Land\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Hole Configuration\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Inconel, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill\/Shank Material\u003c\/strong\u003e: Carbide-Tipped\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0.0005 to minus 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 20121600\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: 100261SR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":68385974386994,"sku":"100261SR","price":304.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f53fc430f364b71e1137dd6bed207561.jpg?v=1793902997","url":"https:\/\/voomisupply.com\/products\/value-collection-100261sr-single-flute-gun-drill-bit-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
