M.a. Ford. 27205550A Chucking Reamer 0.0555 in Solid Carbide

Product Description

The M.A. FORD. 27205550A is a solid carbide chucking reamer designed for precise hole finishing in close-tolerance machining applications. With a reamer diameter of 0.0555 inches and a diameter tolerance of +0.0001 to +0.0003 inches, this tool delivers consistent, accurate results in production and maintenance environments. The 4-flute, straight-flute geometry provides smooth cutting action and efficient chip evacuation. An ALtima coating enhances surface hardness and wear resistance for extended tool life. Overall length is 1.5 inches with a flute length of 0.375 inches, making it suited for shallow reaming passes in small-bore work. Machinists, tool-and-die technicians, and maintenance professionals install this reamer in CNC or manual drill presses and milling machines.

This chucking reamer is intended for small-diameter bore finishing where tight dimensional tolerances are required. It is well suited for ferrous and non-ferrous materials in light manufacturing, toolroom, and repair shop environments. The straight cylindrical shank seats directly in standard drill chucks or collet systems without additional adapters. Right-hand cutting direction pairs with conventional clockwise spindle rotation. The Series 272 designation places this tool in M.A. FORD.'s modified-standard line, meaning it may carry application-specific geometry not found in catalog standards.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-diameter reaming
• ALtima coating for improved surface hardness and extended tool life
• 4-flute straight-flute design for smooth bore finishing and efficient chip clearance
• Diameter tolerance of +0.0001 to +0.0003 inches for precise hole sizing
• Straight cylindrical shank compatible with standard drill chucks and collet holders
• Right-hand cut with right-hand spiral direction for use with conventional spindle rotation

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks and collet systems accepting a straight cylindrical shank. Suitable for CNC machining centers, manual drill presses, and milling machines configured for small-diameter bore finishing operations.

Installation Notes

Installation should be performed by qualified machinists familiar with small-diameter rotary cutting tools. Secure the straight shank firmly in a matched collet or drill chuck to minimize runout before operation. Ensure the spindle is fully stopped and the machine is powered down before mounting or removing the reamer. Do not exceed the tool's rated cutting diameter by applying side load or using it as a drill; reamers are finishing tools and require a pre-drilled or bored pilot hole.
