Well, is it a drill or is it a saw? Well, they call it a hole saw so I guess it's a bit of both. In any event, it's a terrific tool for drilling larger diameter holes through a variety of material. However, when you're boring through thick soft wood like this, well, you can run into a couple of obstacles.
In soft woods, hole saws have a tendency to clog with sawdust, requiring me to stop and frequently clean the teeth. Also when I finish drilling, I'm usually left with a wooden plug inside that can only be removed with a bit of prying and pushing.
Sometimes even that doesn't work, making it necessary for me to remove the arbor and push out the plug. This hole saw from Lyropa Tool has carbide teeth that never clog. And even better, the wooden plug can be removed by simply pressing this button on the arbor and sliding the saw upward toward the drill.
Slide it back down and I'm ready to drill again. So if you've got a lot of holes to bore, or is it saw, especially through thick material, well, this is a tool you might want to consider. It also has a quick release mechanism here which makes it very fast to change out cutters. It comes in a kit with 11 different size cutters and if you'd like more information about this tool, visit ronhazelton.com.
