Spyder Rapid Core Eject Hole Saws

There's no doubt that the lamest part of using a hole saw is ejecting the core from the saw. I wonder how many flat head screwdrivers have been irreparably damaged over the years. A while back, Lennox advanced a solution to this problem with their Speed Slot line. These saws come with a cool "step" pattern up the side of the saw, giving you a series of spots to pry your screwdriver against. I have a set and they're nice. Milwaukee recently released a similar design.

But Spyder is wiping the slate clean and approaching the problem from an entirely different angle. Their thinking is, "why move the core, when you can move the saw?" It's a cool idea too. How it works is that once you make the cut, a release button lets you slide the hole saw back along the bit. This leaves the core in place where it can be easily removed. Then press and slide the saw back in place.

Another benefit to the system is that you can have two hole saws on the same bit, so if you drill your hole too small (which certainly happens), you can keep the smaller size on the bit and use it as a centering mechanism for the larger one. No more need to put a hole in a scrap of wood and try to secure it in place while you get the cut started.

But wait, there's more! The sliding saw also means you can extend more drill bit if need be, in order to drill at an angle.

Here's a video so you can see what I'm talking about.

Obviously, the centerpiece of the system is the bit. According to Spyder's press release, the saws themselves are compatible with other hole saw systems. This would lead one to believe that other hole saws can be threaded on to the sliding bit and used in conjunction with the Spyder. That said, it could be worth picking up a bit and seeing how it goes.

My one concern with the whole thing is that the bit is totally proprietary. I generally view drill bits as about as replaceable (and durable) as tissues. And this one, because it has to be so long to accommodate the sliding saw, looks particularly at risk. Thankfully, they appear to be sold at Lowes, so a replacement shouldn't be too far away if you break one. But, if it were me at the store, I'd buy two or three from the get-go.

The pricing seems inline with the competition. The saws are available in two formats; bi-metal ($6-$40) and tungsten carbide ($13-$70). The sliding bit is in the $5-$20 range depending on size.

Some at Amazon, more at Lowes.
