No Brass Pilot = No Burn! Unlike traditional miniature router bits using brass-pilots, Amana Tool uses tiny 3/16" diameter ballbearing guides, eliminating burn marks (burnout) caused by brass pilot bits. Innovative carbide tipped design delivers a consistent edge that eliminates hand sanding & filing. Ideal for delicate projects such as: Sign-making & routing letter edges Building musical instruments Flush trimming tight corners High production projectsThe miniature bearing router bits can be used on wood and plastic, andcomes in a variety of profiles including round over, chamfer, flush, bevel trim and rabbet.
