Neptonics 1/2 in Radius Ball Bearing Round-Over Router Bit

Overview

The Neptonics Ball Bearing Round-Over Router Bit is a speargun-building tool for rounding and finishing the edges of speargun bodies and handle frames. Its guided cutting design helps produce consistent curved edges while following the existing contour of the workpiece.

Guided edge finishing

The enclosed ball bearing rides along the workpiece and guides the cutter around straight sections and changing contours. This allows the cutting edge to maintain the round-over profile as the router moves around the speargun or handle frame, making the bit suitable for final edge shaping and smoothing work.
