WOOD magazine review

Top Tool sander is aggressive, powerful, and easy to use

Review Summary

High points: A strong performer in virtually every area makes the 31-300 our Top Tool among belt/disc combo sanders. The most powerful and aggressive sander in our test. No tools needed to make all routine adjustments, including switching the belt-arm orientation. And, unlike most machines in our test, the 31-300 held its belt tracking after the switch. Low points: Cast-iron belt arm is heavy, and requires some strength to move from horizontal to vertical.
Paint wears off platen and causes belt to bounce against platen. (Replacing the belt remedied most of the bouncing.) More points: Miter gauge not included, but 3/4"-wide miter slot accepts a standard tablesaw miter gauge. Power takeoff can be used with optional flap sander or pneumatic drum.
