Magafor 88860001660 Chucking Reamer 0.0654 in Solid Carbide

Product Description

The MAGAFOR 88860001660 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance machining applications. Part of the MAGAFOR Series 8600, it carries a 0.0654-inch diameter with a reamer diameter tolerance of 0.0002 inches, making it suitable for work where bore accuracy is critical. The straight-cylindrical shank seats directly in standard collets or drill chucks, and the bright uncoated carbide construction handles a range of workpiece materials without added coating complexity. With a 4-flute, left-hand spiral geometry and right-hand cutting direction, this reamer improves chip evacuation while maintaining surface finish quality.

This reamer is intended for use in CNC machining centers, manual mills, and drill press setups where small-bore reaming is required. At 1.9700 inches overall length with a 0.4330-inch flute length, it is sized for shallow reaming passes in small-diameter holes, typical in precision instrument components, small hydraulic bodies, or tight-clearance mechanical assemblies. Installation is performed by qualified machinists and tool-and-die professionals. This reamer does not support coolant-through delivery and is not configured as a dowel pin or over/under size reamer.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-bore applications
• 0.0002-inch diameter tolerance for tight-tolerance hole finishing
• 4-flute left-hand spiral geometry with right-hand cutting direction promotes controlled chip flow
• Straight-cylindrical shank for direct collet or drill chuck mounting
• Bright uncoated finish suitable for a range of base materials without coating buildup concerns
• Series 8600 design - compact 1.9700-inch OAL suited for shallow-reach reaming setups

Compatibility

Designed as a Series 8600 OEM-style chucking reamer for use in standard straight-shank collets and drill chucks sized for small-diameter tooling in the 0.0500 to 0.0999-inch reamer diameter range.

Installation Notes

Installation is performed by qualified machinists. Always power down and lock out the spindle before seating or removing the reamer from the chuck or collet. Ensure the shank is fully seated and the collet nut is properly torqued per the toolholder manufacturer specifications before operation. Do not use this reamer as a drill - pre-drill or bore the hole to near-final size before reaming to preserve edge geometry and tolerance.
