Magafor 88860000790 Chucking Reamer 0.031 in Solid Carbide

Product Description

The MAGAFOR 88860000790 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. Built with 4 spiral flutes in a left-hand spiral configuration with right-hand cutting direction, this reamer delivers consistent sizing and a refined surface finish in bored or drilled holes. The reamer diameter is 0.031 inches, corresponding to wire gauge size 68, with a diameter tolerance of 0.0000 to +0.0003 mm for tight, repeatable results. Overall length is 1-5/16 inches with a 9/32 inch flute length. The bright polished finish reduces friction and aids chip evacuation. Machinists and tool-and-die technicians install this reamer in standard chucks on CNC machines, drill presses, and machining centers.

This reamer is suited for precision reaming of small-diameter holes in ferrous and non-ferrous materials where close tolerances are required. The straight shank allows direct mounting in collet chucks or drill chucks without adapters. Applications include instrument manufacturing, mold and die work, aerospace component finishing, and any operation requiring a finish-reamed hole at the 0.031 inch diameter range. The solid carbide construction makes it appropriate for harder workpiece materials and higher-speed operations where high-speed steel tooling would wear prematurely.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• 4 left-hand spiral flutes with right-hand cutting direction for smooth chip evacuation
• 0.031 inch diameter (wire gauge 68) with a tight tolerance of 0.0000 to +0.0003 mm
• Bright polished finish reduces friction and improves surface finish in the reamed hole
• Straight shank for direct mounting in collet or drill chucks without adapters
• Compact 1-5/16 inch overall length suited for confined-reach applications

Compatibility

Designed as a standard chucking reamer for use in CNC machining centers, drill presses, and lathes equipped with collet chucks or drill chucks accepting a straight shank at the 0.031 inch diameter range.

Installation Notes

Installation is performed by qualified machinists. Secure the straight shank firmly in a collet chuck or drill chuck before operation, and verify runout with a dial indicator before engaging the workpiece. Ensure the spindle speed and feed rate are appropriate for solid carbide tooling in the workpiece material. Do not run this reamer in reverse, as the right-hand cutting geometry is designed for forward rotation only.
