Magafor 88860005000 Chucking Reamer 0.1969 in Solid Carbide

Product Description

The MAGAFOR 88860005000 is a solid carbide chucking reamer designed for precision hole finishing in metalworking applications. With a reamer diameter of 0.1969 inches (5.00 mm) and a diameter tolerance of 0.0000 to +0.0004 mm, this tool delivers tight, consistent bore dimensions where fit and finish matter. The straight shank makes it compatible with standard drill chucks and collet holders on machining centers, CNC lathes, and bench drill presses. Six spiral flutes with a left-hand spiral direction and right-hand cutting action help evacuate chips efficiently while maintaining a bright, polished finish on the bore wall. Machinists and tool-and-die tradespeople rely on this class of reamer for final-pass sizing of close-tolerance holes.

This chucking reamer is suited for precision reaming operations in ferrous and non-ferrous metals where a tight diameter tolerance is required. The 0.1969-inch diameter places it in the 5.00 mm size class, making it a practical choice for hydraulic fitting ports, dowel pin bores, and precision bushing seats in both production shop and job shop environments. Its solid carbide construction handles harder workpiece materials and extended run cycles better than high-speed steel alternatives, making it appropriate for production runs as well as prototype work.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• 0.1969-inch (5.00 mm) diameter with a tolerance of 0.0000 to +0.0004 mm for close-tolerance bore finishing
• Six spiral flutes with left-hand spiral geometry and right-hand cutting direction for efficient chip evacuation
• Bright (polished) coating provides a smooth cutting surface and reduces built-up edge
• Straight shank for use in standard chucks and collet holders
• Overall length of 3-25/64 inches with a 29/32-inch flute length for controlled reach in shallow-to-moderate depth bores

Compatibility

Designed as an OEM-style precision reamer for use in standard straight-shank chuck and collet setups on machining centers, CNC lathes, and drill presses requiring a 0.1969-inch finished bore diameter.

Installation Notes

Chucking reamers are installed and operated by machinists following standard machining center or drill press lockout procedures before tooling changes. Ensure the shank is fully seated and clamped securely in the chuck or collet before running. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Do not use a reamer to remove excessive stock - pre-drill or bore the hole to within 0.005 to 0.015 inches of final diameter before reaming, following shop standard practice.
