Amana Tool Miniature Bits with 3/16" Ball Bearing Guide

Thank you for shopping with us!

Reach tighter corners without burn marks! The smallest bearing guides in the industry!

If you’ve often wanted to trim and shape small details in tight corners but were disappointed by the scoring and burning left behind by solid pilot bits, we have what you’ve been looking for: the most commonly used profiles in miniature sizes—complete with tiny ball bearing guides. These bits are perfect for signs, lettering, small boxes, and musical instruments—essentially any project that requires tiny flush trimming or shaping. Precisely machined and carbide-tipped.

-Bearings stay cool, unlike brass pilots
-Rout intricate contours for delicate projects
-Perfect for crafters & hobbyists
-Lettering/Sign-making
-Fine musical instruments

Recommendation: The miniature router bits with 3/16” and 1/4” diameter ball bearing guides were designed for use in intricate and delicate projects with or without tight spaces. Do not cut material more than half the diameter of the bearing and slow down feed to reduce load. Not guaranteed due to their extremely small size.
