Magafor 88860001830 Chucking Reamer 0.072 in Solid Carbide

Product Description

The MAGAFOR 88860001830 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance machining applications. Built with 4 flutes and a spiral flute geometry with left-hand spiral direction and right-hand cutting direction, this reamer delivers smooth, accurate stock removal. The 0.072-inch diameter and bright polished finish make it well-suited for small-bore finishing where surface quality and dimensional accuracy are critical. With an overall length of 1-31/32 inches and a flute length of 7/16 inch, it is sized for compact setups. Licensed machinists and toolroom technicians are the primary users.

This chucking reamer is intended for use in drill presses, CNC machining centers, lathes, and manual mills where a straight shank toolholder or drill chuck is available. It is suited for finishing pre-drilled or bored holes in ferrous and non-ferrous metals where a close-tolerance final bore diameter is required. The diameter tolerance of 0.0000 to +0.0003 mm ensures consistent, repeatable results in production and job-shop environments alike. Its compact overall length makes it a practical choice for shallow-hole applications in confined workpiece geometries.

Key Features

• Solid carbide construction for wear resistance and rigidity in precision reaming
• 4-flute spiral geometry with left-hand spiral and right-hand cutting direction
• Bright polished finish reduces friction and aids chip evacuation
• Straight shank fits standard drill chucks and straight-bore toolholders
• Tight diameter tolerance of 0.0000 to +0.0003 mm for close-fit hole finishing
• Compact 1-31/32 inch OAL suits confined workpiece setups

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for straight shank chucking reamer applications requiring a 0.072-inch finished bore diameter in drill presses, CNC machines, lathes, and milling setups.

Installation Notes

This tool is installed by machinists or toolroom technicians in a straight-bore chuck or collet holder. Always ensure the workpiece and spindle are properly secured before engaging the reamer, and confirm the pre-drilled hole is within the recommended stock allowance for the reamer diameter. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never force the reamer into an undersized hole.
