If you’re like me, you’ve got a box full of wood hole saws. But if you’re an electrician (or the complete tool geek), you’ll want a set of metal hole saws, too. And Greenlee’s got a new set they say cuts 30% faster, lasts longer, and has more features than the competition. So how the hell does that work?
First, they’ve tossed in a variable pitch sawblade, in this case a 4-6. (I use a 12-16 on my metal bandsaw, and it’s awesome, riding that perfect line between low-count blow-through-the-thick-stuff and higher-count please-don’t-hang-on-the-edge-of-tubing.) And they’ve hardened the teeth to keep ’em sharp longer. They say their oxide finish prevents chip buildup as well, but that seems pretty common to me.
Feature-wise you’re looking at a quick-change arbor with a really nice-looking knurled grip — as well as a removable depth stop.
Individual saws start at around $8 and range up to around $50, but you can find three-piece and five-piece kits, too, from around $150 including the arbor and all the goodies.
