Magafor 88860003050 Chucking Reamer 0.12 in Solid Carbide

Product Description

The MAGAFOR 88860003050 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a diameter of 0.12 inches and a diameter tolerance of 0.0000 to +0.0004 mm, this reamer delivers tight, repeatable bore sizing required in toolrooms, job shops, and production environments. The 6-flute spiral design with a left-hand spiral and right-hand cutting direction promotes smooth chip evacuation and a fine surface finish. The bright polished coating reduces friction during the cut. Machinists and tool-and-die professionals install this reamer in CNC machining centers, drill presses, or manual lathes using a standard straight shank chuck setup.

This chucking reamer is suited for finishing pre-drilled or bored holes to close tolerances in ferrous and non-ferrous metals. The 2.25 inch overall length and 19/32 inch flute length make it appropriate for shallow to moderate depth holes in precision components such as bushings, fixtures, and dowel pin bores. It corresponds to a number 31 wire gauge diameter, making it useful when working from wire gauge drill charts. The straight shank allows direct mounting in a drill chuck or collet without an adapter.

Key Features

• Solid carbide construction for hardness and wear resistance in demanding materials
• 6-flute spiral geometry with left-hand spiral for smooth chip flow and improved finish quality
• Right-hand cutting direction compatible with standard spindle rotation
• Diameter tolerance of 0.0000 to +0.0004 mm for tight, repeatable hole sizing
• Bright polished finish reduces cutting friction and aids in chip release
• Straight shank fits standard drill chucks and collets without additional tooling

Compatibility

Designed as an OEM-style precision reamer for use in CNC machining centers, drill presses, and manual lathes equipped with a standard straight shank drill chuck or collet capable of holding a 0.12 inch shank diameter.

Installation Notes

This reamer is installed and operated by machinists or toolroom professionals. Always secure the straight shank fully in the chuck or collet before operation and verify runout with a dial indicator when tolerance-critical work is required. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality. Never use a reamer to remove excessive stock - pre-drill or bore the hole to within a few thousandths of final diameter before reaming.
