The “-4″ designation means that this sander is equipped with a 4-1/2″ x 16” PSA/Rubber-backed Pad. Despite the picture, this model does come equipped with clamp-style clips to hold non-adhesive sandpaper in place.

This Orbital Action Longboard can do anything. Used by countless autobody techs, boat repair specialists, industrial workers, and woodworkers for nearly 70 years of constant production, the 3800 can do everything and anything and it can get it done to the highest standard.

Known as a Master’s Tool, it endlessly rewards a skilled user. The better you are, the more it can do. Heavy duty to feather-finishing.

While anyone can pick up this sander and process material due to its friendly 3/32″ orbit, it’s capabilities scale with skill and it’s air control means that the 3/32″ on this can run hard enough to block, sand, process all metal, stainless, aluminum, fiberglass, wood, primer & paint, and even clearcoat. If you’re skilled enough, you might never have to buy another sander again.

Powered by Hutchins’ legendary 800 Motor that has been improved upon and been continuously in production for close to 70 years, this is a bulletproof tool (if you oil it after the workday this tool will easily last you decades of daily work).

For example:

1. Working on cars, the 3800 and a 7544 (3/32″ water sander to make paint and wet a breeze) would get the job done.
2. If you’re in an industrial setting, you could just have the 3800 for processing metal, stainless, alum, fiberglass or any other industrial material.
3. Woodworking, you would be well-served to pick up a 4500 or a Mini-Straightline to optimize the finishing stages.
4. For marine specialists, we know they are getting tighter on vacuum requirements so please check out the 4932 (3800VA) or the 4932-4 which is equipped with a 4-1/2″ x 16″ Pad (or the 3806 with a 8″ x 18″ Pad).
