Simple flycutter mods to improve tool life, reduce cutting forces, better finish.

[Mook]

This video demonstrates how to improve the performance of a budget flycutter through simple machining modifications. The process includes adding a 15° rake locator block, grinding a permanent 5° clearance on the toolbit, and preparing the cutting edge with a 45° approach angle and small radius. These changes optimise tool geometry, reduce regrinding, keeping the point on the centre, and balance cutting forces for better milling efficiency. The video also covers spindle rigidity, safety considerations, and surface finish results.
