Magafor 88860003130 Chucking Reamer 0.1232in Carbide

Product Description

The MAGAFOR 88860003130 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a cutting diameter of 0.1232 inches (3.13 mm) and a diameter tolerance of 0.0000 to +0.0004 mm, this reamer delivers tight, repeatable bore sizing on the finish pass. The straight shank mounts directly in standard drill chucks or collet holders. Six spiral flutes with a left-hand spiral and right-hand cutting direction clear chips efficiently while maintaining a bright, polished finish on the bore wall. This tool is intended for use by machinists and tool-and-die professionals working to close-tolerance specs.

This reamer is suited for light-material removal on pre-drilled or bored holes where final diameter accuracy is critical. Typical applications include reaming dowel pin holes, bearing bores, and precision fit holes in steel, aluminum, and similar machinable metals. With an overall length of 2.25 inches and a flute length of 0.594 inches, it is sized for shallow-to-moderate depth holes in bench, mill, or drill press setups. The bright carbide finish reduces built-up edge in non-ferrous materials.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding bore finishing
• 0.1232 inches (3.13 mm) cutting diameter with tolerance of 0.0000 to +0.0004 mm for precise sizing
• 6 spiral flutes with left-hand helix and right-hand cut for smooth chip evacuation
• Bright (polished) coating minimizes surface friction and supports finish quality
• Straight shank compatible with standard drill chucks and collet holders
• 2.25 inches overall length with 0.594 inches flute length for shallow precision bores

Compatibility

Designed as a straight-shank chucking reamer for use in drill presses, milling machines, and CNC machining centers equipped with standard collet or drill chuck toolholding. Not specified as a dowel pin or over/under size reamer.

Installation Notes

Chucking reamers are installed and removed by machinists following standard machine shop practices. Always bring the spindle to a full stop before changing tooling and ensure the shank is fully seated and clamped in the holder before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Follow applicable shop safety protocols and machine manufacturer guidelines for speed and feed selection when reaming.
