M.a. Ford. 27241300 Chucking Reamer Letter Z Solid Carbide

Product Description

The M.A. FORD. 27241300 is a solid carbide chucking reamer designed to produce accurate, finished-diameter holes in ferrous and non-ferrous workpieces. Built to Letter Z sizing, it cuts at a nominal diameter of 0.4130 inches with a tolerance of +0.0001 to +0.0004 inches, making it well-suited for precision bore finishing where tight fits are required. The straight flute geometry and right-hand cut direction provide clean chip evacuation in through-hole and blind-hole applications. This reamer is installed in CNC machining centers, manual mills, and drill presses by machinists and tool-and-die professionals who require repeatable hole quality.

This reamer is appropriate for production and job-shop environments where Letter Z diameter holes must meet close-tolerance specifications. The straight shank allows direct mounting in standard drill chucks and collet holders without special adapters. Its solid carbide construction supports use in harder workpiece materials and at higher speeds compared to high-speed steel alternatives. The 6-flute design distributes cutting load evenly, reducing chatter and improving surface finish in both light and moderate-feed finishing passes.

Key Features

• Solid carbide construction for wear resistance and performance in harder materials
• Letter Z diameter (0.4130 inches) with a close tolerance of +0.0001 to +0.0004 inches
• 6 straight flutes with right-hand spiral direction for smooth, even cutting action
• Straight shank compatible with standard chucks and collet systems
• Uncoated finish suitable for use with cutting fluids across a range of workpiece materials
• Series 272 design optimized for chucking reamer applications

Compatibility

Designed as a chucking reamer for use in standard drill chucks and collet holders that accept straight-shank tooling in the Letter Z diameter range.

Installation Notes

Installation and operation of chucking reamers should be performed by qualified machinists familiar with rotating cutting tool safety. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Verify chuck or collet runout before use, as excessive runout will degrade hole tolerance and tool life. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
