Magafor 88860005030 Chucking Reamer 0.198 in Solid Carbide

Product Description

The MAGAFOR 88860005030 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production environments. With a cutting diameter of 0.198 inches (5.03 mm) and a diameter tolerance of 0.0000 to +0.0004 mm, this reamer holds tight size control for close-tolerance bore applications. The straight shank mounts directly in a drill chuck or collet holder on a drill press, lathe, or CNC machining center. Six flutes with a left-hand spiral geometry and right-hand cutting direction improve chip evacuation and surface finish quality. A bright polished finish reduces friction during the cut. Machinists and tool-room technicians are the primary users.

This reamer is suited for finish-reaming operations in ferrous and non-ferrous materials where bore diameter accuracy and surface finish are critical. At 3-25/64 inches overall length with a 29/32-inch flute length, it fits standard toolholding setups for small-diameter precision work in the 0.150 to 0.199-inch diameter range. Typical applications include dowel pin holes, bearing bores, and hydraulic or pneumatic component passages that require controlled fit and finish.

Key Features

• Solid carbide construction for superior wear resistance and rigidity in small-diameter reaming
• 0.198-inch (5.03 mm) cutting diameter with a tolerance of 0.0000 to +0.0004 mm for close-tolerance bores
• Six-flute left-hand spiral geometry promotes efficient chip flow with right-hand cutting direction
• Straight shank for direct chuck or collet mounting on standard machine tools
• Bright polished finish reduces built-up edge and cutting friction
• 29/32-inch flute length provides adequate engagement depth for typical small-bore applications

Compatibility

Designed as a machine chucking reamer for use in straight-shank toolholders, drill chucks, and precision collets on drill presses, lathes, and CNC machining centers handling bores in the 0.150 to 0.199-inch diameter range.

Installation Notes

Installation is performed by a machinist or toolroom technician. Secure the straight shank firmly in a drill chuck or collet to the full grip depth before use. Always bring the spindle to a complete stop before changing or inspecting the reamer. Use appropriate cutting fluid for the workpiece material to maximize tool life and bore finish quality.
