Magafor 88860001850 Chucking Reamer No. 49 Solid Carbide

Product Description

The MAGAFOR 88860001850 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance machining applications. Built to wire gauge No. 49, it produces a 0.0728 inch diameter bore with a tolerance of plus or minus 0.0002 inch, making it suitable where dimensional accuracy is critical. The reamer features four spiral flutes with a left-hand spiral and right-hand cutting direction, a combination that reduces chatter and improves chip evacuation in through-hole operations. The straight-cylindrical shank allows direct mounting in standard drill chucks, collet chucks, or floating reamer holders on CNC and manual machine tools.

This reamer is sized for small-diameter precision work common in aerospace, medical device, instrument manufacturing, and toolroom environments. The solid carbide construction handles abrasive materials and hardened workpieces better than high-speed steel alternatives. With an overall length of 1.97 inches and a flute length of 0.4330 inch, the 88860001850 is compact and suited for shallow through-holes or light reaming passes. It runs without coolant-through capability, so external coolant or cutting fluid applied at the entry point is standard practice for this tool type.

Key Features

• Solid carbide construction for wear resistance and long tool life in abrasive or hard materials
• No. 49 wire gauge diameter, 0.0728 inch, with a reamer diameter tolerance of 0.0002 inch for tight-tolerance finishing
• Four left-hand spiral flutes with right-hand cutting direction to reduce chatter and improve chip control
• Bright uncoated finish - compatible with a wide range of cutting fluids without coating compatibility concerns
• Straight-cylindrical shank fits standard drill chucks and collet holders without adapters
• Series 8600 designation for consistent specification across MAGAFOR tooling families

Compatibility

Designed as a standard chucking reamer for use in CNC machining centers, drill presses, and manual lathes equipped with drill chucks or collet-style toolholders accepting a straight-cylindrical shank. Suitable for ferrous and non-ferrous materials where a 0.0728 inch finished bore diameter is required.

Installation Notes

Chucking reamers of this diameter should be installed by a machinist or toolroom professional familiar with small-diameter cutting tool handling. Ensure the spindle and workpiece are fully secured and the machine is powered down before tool changes. Always apply appropriate cutting fluid at the tool entry point, as this tool does not support coolant-through delivery. Use the recommended surface footage and feed rate for solid carbide reamers based on workpiece material to avoid tool breakage at this small diameter.
