M.a. Ford. 27247240 Chucking Reamer 12mm Solid Carbide

Product Description

The M.A. FORD. 27247240 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. Built with a 12 mm (0.4724 inch) diameter and six straight flutes, it delivers consistent, accurate sizing across a wide range of materials. The right-hand cutting direction and straight shank make it compatible with standard drill chucks and collet holders. With a reamer diameter tolerance of +0.008/+0.015 mm, this tool is suited for close-tolerance work where hole quality and repeatability are critical. Machinists and toolroom professionals rely on this style of reamer for production and maintenance operations alike.

This chucking reamer is intended for use in machine tool setups including CNC machining centers, turret lathes, and drill presses where a straight-shank, chuck-held reamer is appropriate. It is well suited for reaming through-holes and blind holes in ferrous and non-ferrous metals. The uncoated solid carbide construction is a practical choice for shops that prefer consistent performance without coating variables in precision tolerance work. No coolant-through capability is required for typical low-to-moderate speed reaming operations where flood or mist coolant is applied externally.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• 12 mm (0.4724 inch) reamer diameter with a tight tolerance of +0.008/+0.015 mm
• Six straight flutes for smooth cutting action and consistent chip evacuation
• Right-hand cutting direction with straight shank for standard chuck or collet mounting
• Uncoated finish - no coating variation affecting final hole diameter
• Series 272 designation for straightforward cross-referencing within M.A. FORD. tooling lines

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in standard drill chucks and collet holders accepting a straight-shank tool in the 10.00 mm to 20.00 mm reamer diameter range.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle and chuck are fully stopped and the machine is powered down before loading or removing the reamer. Secure the straight shank firmly in the chuck or collet to the appropriate clamping specification for the holder being used. Apply appropriate cutting fluid or coolant externally during operation to extend tool life and maintain hole finish quality.
