M.a. Ford. 27212990 Chucking Reamer 3.30mm Solid Carbide

Product Description

The M.A. FORD. 27212990 is a solid carbide chucking reamer designed for precision hole finishing in metal and machined components. With a reamer diameter of 3.30mm and a diameter tolerance of +0.005 to +0.010mm, it delivers tight, repeatable bore sizing suited to close-tolerance work. The straight, right-hand flute geometry and right-hand cutting direction produce a clean, consistent finish pass. Four flutes provide adequate chip clearance while maintaining rigidity in the cut. This reamer is installed and run by machinists and tool-and-die professionals using standard chucking equipment such as drill presses, lathes, and CNC machining centers.

The 27212990 is appropriate for production and maintenance machining environments where bore finishing to a precise diameter is required. Its 19.00mm flute length and 63.00mm overall length make it well suited for shallow to moderate depth holes in the 3.30mm diameter range. The straight-cylindrical shank allows direct chucking in standard collets or drill chucks without the need for specialty toolholders. The bright, uncoated finish makes it a practical choice for general-purpose reaming where coating cost is not justified by the application.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• 3.30mm reamer diameter with a tolerance of +0.005 to +0.010mm for close-tolerance bore finishing
• 4-flute, straight-flute design with right-hand cutting direction
• 19.00mm flute length suitable for shallow to moderate depth holes
• Straight-cylindrical shank for direct chucking in standard collets or drill chucks
• Bright, uncoated finish for general-purpose applications

Compatibility

Designed as an OEM-style replacement or direct-use chucking reamer for standard chucking setups requiring a 3.30mm finished bore diameter; part of M.A. FORD. Series 272.

Installation Notes

Installation is performed by qualified machinists. Secure the straight-cylindrical shank firmly in a compatible collet or drill chuck before operation, and verify runout is within acceptable limits prior to cutting. Shut down and de-energize the machine spindle before tool changes. Do not use this reamer as a drill; it is a finishing tool and requires a pre-drilled or bored hole at the correct undersize before reaming.
