Magafor 88860001790 Chucking Reamer 0.0705in Solid Carbide

Product Description

The MAGAFOR 88860001790 is a solid carbide chucking reamer engineered for precision hole finishing in tight-tolerance applications. Built to Series 8600 specifications, it produces a reamed diameter of 0.0705 inches with a diameter tolerance of 0.0002 inches, making it well-suited for work where bore accuracy is critical. The four-flute, left-hand spiral geometry paired with right-hand cutting direction promotes smooth chip evacuation and stable cutting action. With an overall length of 1.9700 inches and a flute length of 0.4330 inches, this compact reamer is designed for use in CNC machining centers, drill presses, and manual lathes where small-bore reaming is required. It is installed by machinists and tool-and-die technicians working in precision metal fabrication environments.

This reamer is appropriate for precision finishing of small-diameter bores in ferrous and non-ferrous materials. The solid carbide construction handles harder workpiece materials and maintains dimensional accuracy over extended production runs. The straight-cylindrical shank seats directly into collet chucks or drill chucks, making tool changes straightforward in both manual and automated setups. At 0.0705 inches (1.79 mm) diameter, this tool fits applications requiring bore sizes in the 1.00 mm to 2.00 mm range, common in instrument components, hydraulic valve bodies, and precision mechanical assemblies.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming operations
• Four-flute left-hand spiral geometry with right-hand cutting direction for controlled chip flow
• Reamer diameter tolerance of 0.0002 inches for tight-tolerance bore finishing
• Bright/uncoated finish suitable for a range of workpiece materials
• Straight-cylindrical shank compatible with standard collet and drill chuck toolholding
• Compact 1.9700-inch overall length designed for small-bore, close-clearance applications

Compatibility

Designed as an OEM-style precision reamer for small-bore finishing applications in the 1.00 mm to 2.00 mm diameter range, compatible with standard collet chucks and drill chucks accepting a straight-cylindrical shank.

Installation Notes

Installation and use of this reamer should be performed by qualified machinists following established shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the tool from the chuck. Secure the straight-cylindrical shank firmly in a collet or drill chuck to minimize runout, which directly affects finished bore tolerance. Do not exceed manufacturer-recommended cutting speeds and feeds for the workpiece material being reamed.
