Arc360 Hole Cutter

Add to Wishlist
Part# 12-01977
MFR Model# ARC-360


Panel knock put punches and hole saws work well for holes that are arenít too big but it gets harder and more expensive as the size of the hole increases.

You can cut holes with a router but cutting holes with a router is a cumbersome ordeal. The router is really just too big a tool to be swinging 360 degrees easily. You can set it to cut holes down to around 1.5 inches and up to around 10 inches. The toolís small size allows you to easily see your work as you are cutting. If you want an arc you can start and stop anywhere you want. It will cut any thickness of sheet aluminum.

The cutting speed in 032 thick 2024-T3 aluminum is around 40 inches per minute so you can cut a 4-inch diameter hole in less than 20 seconds.

Fine tool for my projects... BUT,.. replacement bits ( not 1/4 shank ) are expensive so if you change out the Angle Drill at Harbor Freight for one that uses 1/4 bits @ $11.00ea on EBAY it seems to work much, much better and I buy the Carbide bits...they cut like butter.....Ive done a dozen holes so far and so far so good. Just an FYI.
