M.a. Ford 27203120 Chucking Reamer 1/32 in Solid Carbide

Product Description

The M.A. FORD 27203120 is a solid carbide chucking reamer designed for precision hole finishing in machined components. With a 1/32 inch (0.0312 inch decimal) cutting diameter and a tight tolerance of +0.0001 to +0.0003 inches, this reamer delivers accurate, repeatable hole sizing in production and toolroom environments. The straight flute geometry and right-hand cutting direction make it well suited for through-hole reaming in short-chipping materials. A straight shank allows direct chucking in standard drill chucks, collet chucks, and floating reamer holders. Machinists and tool-and-die professionals reach for this tool when bore finish and dimensional accuracy are the priority.

This reamer is intended for small-diameter precision work in ferrous and non-ferrous metals where a 1/32 inch final bore diameter is required. The 1/4 inch flute length accommodates shallow holes typical of this diameter class, while the compact 1-1/2 inch overall length suits short-reach setups on CNC machining centers, knee mills, and drill presses. It is part of M.A. FORD Series 272 and ships as a single unit, making it practical for both production restocking and one-off toolroom applications.

Key Features

• Solid carbide construction provides rigidity and wear resistance at small diameters
• Diameter tolerance of +0.0001 to +0.0003 inches for precise hole sizing
• Straight flute design suited for right-hand through-hole reaming in short-chipping materials
• Straight shank compatible with standard drill chucks and collet holders
• 4-flute configuration balances cutting load and surface finish at this diameter
• Uncoated carbide substrate ready for use as-delivered or for application-specific coating

Compatibility

Designed as an OEM-style precision reamer for use in standard chucking setups requiring a 1/32 inch finished bore diameter; fits any machine spindle or chuck accepting a straight shank at this diameter range.

Installation Notes

Installation and use of this tool should be performed by a qualified machinist familiar with small-diameter carbide tooling. Always power down and lock out the machine spindle before loading or removing the reamer. Carbide tooling is brittle at small diameters — avoid side loading, interrupted cuts, or excessive runout in the holder, as these conditions can cause breakage. Confirm chuck or collet grip is centered and secure before initiating the cut.
