HUDY 107634 Arm Reamer 4.0 x 120mm Replacement Tip Edition  [HSP-107634]

Surgical Hole Resizing for RC Arms

The HUDY 107634 Arm Reamer gives RC enthusiasts a controlled way to refine hole fits on 1/8 scale suspension arms. Its precision action removes tight spots while preserving material strength.

Fix Binding for Better Handling

A binding pivot point can make a chassis nervous on corner entry. The HUDY 107634 reamer cleans up imperfect holes so the arm swings with a consistent, predictable motion.

Designed Around 1/8 Scale Needs

This reamer uses a 4.0mm tip and a 120mm shaft length suited to typical 1/8 scale parts. The hand-ground cutting pattern trims plastic neatly, avoiding fraying or overstress of the arm material.

Practical Reaming Procedure

• Place the reamer tip into the arm mounting hole.
• Rotate while gently pushing to enlarge the bore.
• Advance until the tool hits the handle, then back out with rotation to clear the tool.

Performing these steps gives a clean, correctly sized bore that reduces binding and improves suspension response.
