Built from solid carbide with a bright\/uncoated finish, it delivers consistent performance across a broad range of materials including steel, alloy steel, stainless steel, cast iron, aluminum silicate, nickel alloy, titanium, and titanium alloys. The bit features a 135-degree split point, a right-hand spiral flute, and a web-thinned, tapered-web construction that reduces entry force and improves chip evacuation. At 0.368 inches (letter size U) in diameter, it fits standard straight-cylindrical shank toolholders and is suited for general-purpose production drilling.\u003c\/p\u003e\u003cp\u003eThis bit is appropriate for use in machine shop environments, CNC drilling operations, and manual drill press setups where short, rigid tooling is preferred to minimize deflection. The slow spiral flute geometry suits harder materials and work-hardening alloys. The 5xD flute-to-diameter ratio provides adequate chip clearance without sacrificing rigidity. It is typically used by machinists and tool-and-die professionals in both job shop and production settings where hole tolerances and tool life are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for hardness and wear resistance in ferrous and non-ferrous alloys\u003c\/li\u003e\n\u003cli\u003e135-degree standard point angle with web-thinning for reduced thrust and cleaner entry\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute geometry suited to hard materials including stainless steel and titanium alloys\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with straight-cylindrical shank for compatibility with standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish maintains dimensional accuracy and suits applications where coating buildup is a concern\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0 to -0.013 mm for consistent, repeatable hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-cylindrical shank toolholders and drill chucks accepting 0.368-inch shanks.

Secure the shank fully in a properly sized drill chuck or collet before operation, and verify spindle runout is within acceptable limits to avoid premature tool wear. Power down and de-energize the machine before changing tooling. Carbide tooling is brittle and should not be subjected to side-loading or interrupted cuts beyond the tool's rated capacity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.368 inches (Letter Size U \/ 9.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: Slow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-13\/16 inches (46.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.013 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 215\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 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: 215-3680\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739229782322,"sku":"215-3680","price":96.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4a25cb6fca78423402be763ec42128e_580dc065-6866-41b8-bdc6-b9e01175220c.jpg?v=1788811764","url":"https:\/\/voomisupply.com\/products\/osg-215-3680-drill-bit-0-368-in-solid-carbide-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
