Magafor 88860005990 Chucking Reamer 0.2358 in Carbide

Product Description

The MAGAFOR 88860005990 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production environments. With a reamer diameter of 0.2358 inches (5.99 mm) and a diameter tolerance of 0.0000 to +0.0004 mm, this tool delivers tight, repeatable results in ferrous and non-ferrous materials. The 6-flute geometry with left-hand spiral fluting promotes smooth chip evacuation while the right-hand cutting direction maintains conventional rotation. A bright polished finish reduces friction and helps extend tool life. Machinists and tool room technicians use this reamer in CNC machining centers, knee mills, and drill presses where straight-shank toolholders are standard.

This chucking reamer is suited for finish reaming operations requiring close hole tolerances in production and job shop settings. The straight shank allows direct clamping in standard chucks or collet systems without additional adapters. With an overall length of 3-31/32 inches and a flute length of 1-7/64 inches, it handles typical through-hole and blind-hole applications in light to medium workpiece depths. It is not configured as a dowel pin reamer or an over/under size reamer, making it appropriate for standard nominal hole sizing at the 0.2358-inch diameter.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard or abrasive materials
• 6-flute, left-hand spiral design promotes efficient chip flow during right-hand cutting
• Diameter tolerance of 0.0000 to +0.0004 mm supports tight hole finish requirements
• Bright polished coating reduces built-up edge and friction at the cutting zone
• Straight shank compatible with standard chucks and collet toolholders
• Compact overall length of 3-31/32 inches suits common workpiece setups without excessive overhang

Compatibility

Designed for use in standard straight-shank chucks and collet systems on CNC machining centers, manual mills, and drill presses requiring a 0.2358-inch finish reamer in the 5.00 to 6.00 mm diameter range.

Installation Notes

Installation and use should be performed by qualified machinists familiar with reaming operations and machine tool setup. Secure the straight shank firmly in a collet or chuck to minimize runout before engaging the workpiece. Power down and lock out the machine before changing or inspecting tooling. Use appropriate cutting fluid for the workpiece material to maintain tool life and hole finish quality.
