Working with a roller bearing guide
The roller bearing guide helps when routing edges with router bits without a pilot pin or ball bearing.
Fit the pilot to the routing base using the nut.
Guide the power tool along the workpiece edge with a uni-form feed.
Lateral clearance:
To change the amount of material being removed, you can adjust the lateral clearance between the workpiece and the guide roller on the roller bearing guide.
Loosen the screw, set the lateral clearance you want by turning the screw, then retighten the screw.

Mi sapete dire come si chiama questa guida che viene utilizzata con un tifilatore?
