Magafor 88861000570 Chucking Reamer Wire 74 0.0224 in

Product Description

The MAGAFOR 88861000570 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance machining applications. Built to wire gauge size 74, it produces a 0.0224-inch diameter bore with a reamer diameter tolerance of 0.0002 inches, making it suited for applications where dimensional accuracy is critical. The tool features 4 spiral flutes in a left-hand spiral configuration with right-hand cutting direction, a bright uncoated finish, and a straight-cylindrical shank for straightforward chuck mounting. Overall length is 1.535 inches with a flute length of 3/32 inches. Machinists and toolroom professionals working in precision manufacturing, instrument fabrication, or small-bore finishing operations are the primary users of this tool.

This reamer is appropriate for finishing pre-drilled or bored holes in ferrous and non-ferrous materials where surface finish and hole diameter consistency are paramount. The Series 8610 designation places it within MAGAFORs line of small-diameter solid carbide reamers. It is particularly well-suited to CNC machining centers, drill presses, and manual lathes where a collet or drill chuck can secure the straight shank securely. No coolant-through capability is present, so external flood or mist cooling should be used when required by the workpiece material.

Key Features

• Wire gauge size 74 with 0.0224-inch reamer diameter for micro-bore finishing
• Solid carbide construction provides rigidity and wear resistance at small diameters
• 4 spiral flutes, left-hand spiral with right-hand cutting direction for efficient chip evacuation
• Reamer diameter tolerance of 0.0002 inches ensures consistent, repeatable hole sizing
• Bright uncoated finish suitable for a broad range of base materials
• Straight-cylindrical shank compatible with standard collets and drill chucks

Compatibility

Designed as an OEM-style replacement or direct tooling selection for machines equipped with standard straight-shank collet systems capable of accepting small-diameter chucking reamers in the sub-0.05-inch diameter range.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before mounting or removing the reamer from the chuck or collet. Ensure the shank is fully seated and the collet or chuck is tightened to the machine manufacturer specifications before starting the spindle. Because no coolant-through feature is present, verify that external coolant or lubrication delivery is adequate for the workpiece material to prevent heat buildup at this small diameter.
