Magafor 88860003640 Chucking Reamer 0.1433 in Solid Carbide

Product Description

The MAGAFOR 88860003640 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance machining applications. Built with 6 flutes and a spiral left-hand flute geometry with right-hand cutting direction, this reamer delivers smooth, accurate material removal. The 0.1433-inch diameter is held to a tolerance of 0.0000 to +0.0004 mm, making it suitable for close-fit bore work. At 2.25 inches overall length with a 19/32-inch flute length and straight shank, it fits standard chucks and collets on CNC machining centers, drill presses, and manual mills. The bright polished finish reduces friction and aids chip evacuation during operation.

This chucking reamer is used in precision machining environments where final bore diameter and surface finish are critical. It is appropriate for production shops, tool rooms, and maintenance machining operations working with metals such as steel, aluminum, and cast iron. The small diameter range places it in applications requiring fine bore sizing, including pin fits, bushing installations, and hydraulic component finishing. It is typically operated by machinists and tool-and-die professionals who require repeatable, calibrated bore geometry.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 6-flute spiral design with left-hand spiral and right-hand cutting direction for smooth chip flow
• 0.1433-inch diameter held to a tolerance of 0.0000 to +0.0004 mm for precision fitment
• Bright polished finish reduces cutting friction and promotes clean bore surfaces
• Straight shank compatible with standard drill chucks and collets
• Compact 2.25-inch OAL suitable for confined-bore and shallow-depth applications

Compatibility

Designed as an OEM-style chucking reamer for use in standard straight-shank tool holders, chucks, and collet systems on CNC and manual machine tools requiring a 0.1433-inch finished bore diameter.

Installation Notes

Chucking reamers are installed and operated by machinists using calibrated machine tools. Ensure the workpiece is securely fixtured and the spindle is aligned with the pre-drilled pilot hole before engaging the reamer. The pilot hole should be sized appropriately undersized per standard reaming allowance practice. Do not use a chucking reamer as a drill; it is a finishing tool only and should be run at appropriate reaming speeds and feeds for the material being cut.
