With a 1.6 mm (0.0630 inch) diameter and a four-flute straight configuration, this reamer delivers tight dimensional control, holding a diameter tolerance of +0.0001 to +0.0004 inches. The bright, uncoated solid carbide construction provides the rigidity and edge retention needed for accurate sizing in a wide range of workpiece materials. Overall length is 38 mm with a 10 mm flute length, making it well suited for shallow to moderate-depth finishing passes. Machinists and tool-and-die professionals specify this reamer where hole geometry and surface finish are critical.\u003c\/p\u003e\n\u003cp\u003eThe OSG 300-0630 is intended for general machining environments where precise bore finishing is required. Its straight cylindrical shank seats securely in collet chucks, drill chucks, and floating reamer holders on CNC machining centers, turret lathes, and drill presses. The straight-flute geometry is effective in through-holes and blind holes with adequate chip clearance. This reamer is part of the OSG 300D series, which covers the 1.00 mm to 2.00 mm diameter range for small-bore applications in precision component manufacturing, mold work, and fixture production.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for superior rigidity and edge retention in precision reaming\u003c\/li\u003e\n  \u003cli\u003e1.6 mm (0.0630 inch) diameter with tolerance of +0.0001 to +0.0004 inches for tight bore control\u003c\/li\u003e\n  \u003cli\u003eFour straight flutes with right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank for compatibility with standard collet and drill chuck toolholding\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies toolholding setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard chucking reamer for general machining applications requiring a 1.6 mm diameter straight-flute solid carbide tool in the OSG 300D series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with rotary cutting tool practices. Ensure the machine spindle and toolholder are fully powered down and locked out before mounting or removing the reamer. Seat the straight shank fully and evenly in the collet or chuck before tightening to manufacturer-specified clamping procedures for the toolholder in use. Inspect the cutting edges for chipping or wear before each use, as carbide reamers are brittle and sensitive to side loads or interrupted cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 1.60 mm (0.0630 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 38 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 300D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4 inches L x 0.25 inches W x 0.25 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 300-0630\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736007213362,"sku":"300-0630","price":49.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3af7ad9693a92dc89007783f5a05a9f_6d151a74-e5ad-48a7-abd7-22d2e01fb93e.jpg?v=1788775381","url":"https:\/\/voomisupply.com\/products\/osg-300-0630-chucking-reamer-1-6mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
