Built to Series 272 standards, it features a 4.20mm (0.1654 inch) reamer diameter with a tolerance of +0.005 to +0.010mm, making it suitable for applications requiring precise hole geometry. The straight, four-flute geometry and right-hand cutting direction produce clean, consistent finishes on through and blind holes. The bright, uncoated carbide construction handles a wide range of workpiece materials without the added cost of a coating. At 70.00mm overall length with a 22.00mm flute length, it fits standard CNC and manual chucking setups.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is used in machine shop and production environments where hole size accuracy is critical. It is well suited for finishing operations on steel, cast iron, aluminum, and similar machinable materials. The straight-cylindrical shank interfaces directly with drill chucks, collet chucks, and floating reamer holders on CNC machining centers, drill presses, and turret lathes. The right-hand spiral direction and four-flute configuration provide stable cutting and efficient chip evacuation during feed-controlled reaming passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in precision reaming\u003c\/li\u003e\n  \u003cli\u003e4.20mm diameter with a tolerance of +0.005 to +0.010mm for controlled oversize fitment\u003c\/li\u003e\n  \u003cli\u003eFour straight flutes, right-hand cut, for smooth finish and controlled chip flow\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish compatible with a broad range of cutting fluids and workpiece materials\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003e70.00mm overall length with 22.00mm flute length suits short-to-medium depth hole applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard chucking reamer for use in any machine tool equipped with a drill chuck or collet chuck that accepts a straight-cylindrical shank of 4.20mm diameter.

Secure the reamer in a rigid, concentric holder and ensure the spindle is fully stopped before tool changes. Always apply appropriate cutting fluid for the workpiece material to extend tool life and maintain hole finish quality. Feed rate and spindle speed should be set per standard reaming practice for the material being cut; do not use this tool as a drill.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 4.20mm (0.1654 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter Tolerance\u003c\/strong\u003e: +0.005 to +0.010mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 70.00mm (2.75 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 22.00mm (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\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\u003eWeight\u003c\/strong\u003e: 0.025 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: M.A. FORD.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 27216540\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51739785494834,"sku":"27216540","price":75.69,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8ecf12d6adb7f5974cb7f307e39df460_3eb0a06b-2248-41e5-b8cf-19c01a06c361.jpg?v=1788818835","url":"https:\/\/voomisupply.com\/products\/m-a-ford-27216540-chucking-reamer-4-20mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
