Arrowmax AM-423278 Professional Tungsten Steel Hex Ball Driver Tip .078 (5/64) X 120MM  [AM-423278]

Tungsten Hex Tip Made for Accurate RC Work

Designed with model builders in mind, the Arrowmax AM-423278 ball driver tip blends accuracy with toughness. The tungsten steel construction keeps the hex profile sharp under repeated workshop use.

Durability for Repeated Use

Tungsten steel gives the tip a high resistance to wear, so it retains a good fit over many maintenance sessions. That helps prevent rounded fasteners and keeps adjustments precise.

Fine Fastener Capability

The .078 (5/64") dimension suits the small screws commonly used in RC models, and the 120mm overall length provides the extra clearance needed to reach recessed screws cleanly.

Practical Compatibility

Fits a number of hex driver systems and is useful for tasks like gearbox access, servo mounting and motor plate tweaks, providing a secure seat on the screw head for accurate turning.
