I recently made an oak bench with angled legs, and I tried drilling the angled holes in the seat a number of ways. The best drill bit turned out to be a straight router bit. Since these don’t cut to the center, I first drilled a smaller hole with a regular bit and then used the router bit to finish the job. It worked really well, delivering cleaner cuts than a hole saw, spade bit, or even a Forstner. I used the same technique to bore large holes in a sheet of Lexan, again with flawless results.

For safety reasons, I would only try this in a drill press, never freehand, and clamp the work down securely. Also, I increased the drill press speed to 1,000 rpm for both the oak and the plastic, which worked great. Last, if a 1/2-in. router bit shank won’t fit in your chuck, try a 1/4-in. shank.

Shop Fox W1826

The thick, felted bag on this Shop Fox is a plus and a minus. On one hand, it makes the unit much less expensive than collectors with canister filters, and also lighter and easier to hang on the wall. Without a separate plastic bag to catch chips, however, they stay in the felt bag, and the shortish zipper on the bottom makes it tough to shake them out. Otherwise, the W1826 is an excellent value.
