Ford. 27219290 Chucking Reamer 4.90mm Solid Carbide","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\u003cp\u003eThe M.A. FORD. 27219290 is a solid carbide chucking reamer designed for precision hole finishing in machining applications. With a 4.90mm (0.1929 inch) reamer diameter and a bright, uncoated finish, this tool delivers tight dimensional accuracy with a diameter tolerance of +0.005 to +0.010mm over nominal. The overall length is 76.00mm (3.00 inches) with a 25.50mm (approximately 1 inch) flute length. Four straight flutes with right-hand cutting direction provide clean, consistent material removal. Machinists and tool-and-die professionals rely on this type of reamer for bringing pre-drilled or bored holes to final size with high surface finish quality.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for use in CNC machining centers, manual mills, and drill presses where a straight-cylindrical shank is compatible with standard chucks or collet holders. It falls within the 4.00mm to 5.00mm reamer diameter range and is part of M.A. FORD. Series 272. The solid carbide construction makes it appropriate for harder workpiece materials, including cast iron, hardened steel, and non-ferrous alloys, where high-speed steel tooling may wear prematurely. Coolant-through capability is not included in this design.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e4.90mm diameter with +0.005 to +0.010mm over-size tolerance for precision hole finishing\u003c\/li\u003e\n\u003cli\u003eFour straight flutes with right-hand cutting direction for smooth, consistent reaming action\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose machining applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eSeries 272 design, sold in single-unit quantity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use chucking reamer for machining setups requiring a 4.00mm to 5.00mm diameter straight-flute solid carbide reamer with a straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis reamer is installed and operated by machinists in machine shop environments. Before mounting, ensure the spindle or chuck is fully powered down and locked out per facility safety procedures. Secure the straight-cylindrical shank firmly in a compatible chuck or collet to the appropriate holding torque per the machine manufacturer's specifications. Verify correct spindle speed and feed rate for the workpiece material before operation, and confirm the pre-drilled hole is within acceptable stock allowance for reaming.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 4.90mm (0.1929 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 4.00mm to 5.00mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 76.00mm (3.00 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 25.50mm (approximately 0.875 inches)\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.005 to +0.010mm over nominal\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: 272\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0384 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: M.A. FORD.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 27219290\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51732781367602,"sku":"27219290","price":76.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8ecf12d6adb7f5974cb7f307e39df460_05377281-472a-4a40-942f-b8f87680008c.jpg?v=1788746737","url":"https:\/\/voomisupply.com\/products\/m-a-ford-27219290-chucking-reamer-4-90mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
