Accurate Arm Bore Reaming with the EDS 161231

The EDS 161231 arm reamer is intended for precise sizing of suspension arm bores to improve component alignment and movement. Its 1/8 inch (3.175mm) cutting diameter and 120mm length are tailored for common RC arm work in the workshop or pit area.

Feature Highlights

Precision Cutting: Produces a consistent 1/8 inch hole for tight, predictable fitment of pins and studs.
Sturdy Design: Made to withstand routine tuning and rework without losing its profile.
Wide Use Cases: Appropriate for various road, off-road and competition arm types.

Will EDS 161231 change the geometry of my arms?

Used correctly it only cleans and sizes the bore to original dimension, so geometry stays the same while fit and movement improve.

How do I avoid over-reaming?

Work slowly, check the fit often with the pin or stud, and stop as soon as the desired fit is achieved to prevent removing too much material.

What other shop tools pair well with this reamer?

A small bench vise or soft jaws, a drill guide for straight entry, and a set of pin gauges help achieve the best, repeatable results.

Is training needed before use?

Basic familiarity with handheld reamers and jigging parts is helpful; a practice piece is recommended before working on an expensive component.
