About Us

We've been thinking out of the (tool) box since the early 1980s with the introduction of the Handi Disc flexible abrasive wheel. Wow! Cut, sand, grind, and sharpen with one 7" blade that won't shatter or explode. At trade shows across the country, we proved it during product demonstrations with a good swipe of a hammer. On lookers gasped then took a set home. Twenty-five years later, you'll still find us out at trade shows only now with a more extensive line of tools — or which you can also explore here on our website. But, seriously, why have a bunch of tools when one will do? You multi-task and your tools should, too! After the Handi Disc, came
Multi-purpose drill bits that drill masonry, metals hard and soft, PVC, fiberglass, and more. Our Rover Bits not only drill wood vertically but cut horizontally, and our Biter Sheet Material Cutter weighs less than a pound, takes up a corner of your toolbox but turns your hand drill into a powerful double-headed, steerable nibbling tool. What's even better? These unique and useful tools available backed by a lifetime satisfaction guarantee and top-notch customer service support. So, take a look around or visit us at a show.
