Hi! We're the Strong Family - Ann, Joseph and JJ. We've been working on cars and DIY'ing since we can remember. So, back in 1983, when a shattered grinding wheel nearly caused serious injury while we were working on our Bluebird Bus, we decided to come up with a tool that was safer, stronger, better. That first tool has lead to a whole line of 'em and for three generations now our family-owned company has been making specialty cutting and drilling tools that tradesmen and DIYers alike can count on - all backed by our Lifetime Guarantee.
