Magafor 88860003240 Carbide Chucking Reamer 0.1276 in 6 Flute

Product Description

The MAGAFOR 88860003240 is a solid carbide chucking reamer designed for precision hole finishing in metal and hard materials. With a reamer diameter of 0.1276 inches (3.24 mm) and a bright polished finish, it delivers tight bore tolerances in production and toolroom environments. The 6-flute, right-hand cutting geometry with left-hand spiral fluting promotes smooth chip evacuation and reduces chatter during the cut. Overall length is 2.25 inches with a 19/32 inch flute length. This reamer is sized for applications requiring a diameter tolerance of 0.0000 to +0.0004 mm, making it appropriate for close-tolerance work in machining and assembly operations.

This chucking reamer is suited for use in CNC machining centers, drill presses, and manual lathes where a straight shank can be gripped in a drill chuck or collet. It is intended for finishing pre-drilled or bored holes to a consistent diameter in ferrous and non-ferrous materials. The solid carbide construction makes it well suited for hardened materials, cast iron, and abrasive alloys where high-speed steel tooling would wear prematurely. Machinists, tool-and-die makers, and precision fabricators handling small-diameter bore work are the primary users.

Key Features

• Solid carbide construction provides superior wear resistance in hard and abrasive materials
• 6-flute geometry improves surface finish and distributes cutting load evenly
• Left-hand spiral fluting aids chip evacuation while maintaining right-hand cutting direction
• Bright polished coating reduces friction and built-up edge during reaming
• Straight shank fits standard drill chucks and collet holders without special tooling
• Diameter tolerance of 0.0000 to +0.0004 mm supports close-tolerance bore finishing

Compatibility

Designed as an OEM-style precision chucking reamer for use in any machine tool equipped with a straight-shank chuck or collet capable of holding a 0.1276 inch shank diameter.

Installation Notes

Installation and use of this reamer should be performed by qualified machinists familiar with cutting tool setup and speeds-and-feeds selection for carbide tooling. Ensure the machine spindle and chuck are fully stopped before loading or removing the reamer. Carbide tooling is brittle and can fracture if subjected to side loading, interrupted cuts without proper support, or excessive runout in the chuck. Always verify chuck concentricity and use appropriate cutting fluid for the workpiece material.
