Magafor 88860004890 Chucking Reamer 0.1925 in Solid Carbide

Product Description

The MAGAFOR 88860004890 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production environments. With a cutting diameter of 0.1925 inches (4.89 mm) and a tight diameter tolerance of 0.0000 to +0.0004 mm, this reamer delivers consistent, accurate bore sizing in a single pass. The straight shank mounts directly into standard drill chucks or collet holders. Six flutes with a spiral left-hand flute geometry and right-hand cutting direction provide smooth chip evacuation and a refined surface finish. Machinists and tool-and-die professionals use this reamer for finish reaming operations where hole tolerance and surface quality are critical.

This reamer is suited for precision finishing of through-holes and blind holes in ferrous and non-ferrous materials across CNC machining centers, drill presses, and manual mills. The solid carbide construction handles hard or abrasive workpiece materials that would wear down high-speed steel tooling prematurely. Its compact overall length of 3-25/64 inches makes it well-suited for close-clearance setups and shorter-reach fixturing configurations common in production machining.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• 0.1925 inch (4.89 mm) cutting diameter with a tolerance of 0.0000 to +0.0004 mm for tight bore sizing
• 6-flute spiral design with left-hand flute geometry for smooth chip flow
• Right-hand cutting direction compatible with standard CNC and manual spindle rotation
• Bright (polished) finish reduces friction and aids chip clearance
• Straight shank for direct mounting in drill chucks or collet holders

Compatibility

Designed as a general-purpose chucking reamer for use in standard drill chucks and straight-bore collet holders on CNC machining centers, drill presses, and milling machines requiring a 0.1925 inch nominal bore diameter.

Installation Notes

Installation and operation should be performed by a qualified machinist familiar with rotating cutting tool safety. Ensure the machine spindle is fully stopped and the tool holder is secure before mounting or removing the reamer. Use appropriate cutting fluid for the workpiece material to maximize tool life and surface finish. Follow shop-specific feeds and speeds guidelines for solid carbide reaming operations.
