Friends of Tree Cutting,

It's always a pleasure to have answered those enigmatic questions that so few people have dared to ask. And, thanks to advanced home workshop technology, it's now possible to drill curved holes:

How to Drill a Curved Hole

By Andrew Liszewski (http://www.gizmodo.co.uk/author/andrew-liszewski/) on 12 Sep 2016 at 4:30PM

Even if your carpentry skills aren’t much more than having watched a few episodes of Home Improvement, it’s still pretty common knowledge that a drill only works in a straight line. Or does it? Woodshop hacker Izzy Swan (https://www.youtube.com/channel/UCO39zTYpvWL5jx2q15Ma_Hw) created a custom rig that can actually drill a curved hole instead.


By welding a drill bit onto the end of a flex shaft attached to a curved rig, Swan’s unorthodox creation allows a standard power drill to bore holes through wood that curve in any direction he needs. It’s useful for running wires and cables through inside corners of a new home under construction, but also because the idea will also melt your brain a little.

Actually, this could have a lot of uses to create channels to route plumbing, wires, and cables and weaken those pesky 6 X 4 posts.

And, who would doubt that a "woodshop hacker" with the name "Izzy Swan" would not end up with a way to "melt your brain a little".

I like watching Izzy's channel on YouTube, he's always coming up with wacky drill-powered inventions. That's cool that Gizmodo picked up on him. :)

I picked up a Vermont American bit to drill around corners about 12 years ago when I need to pull some wires through a wall corner in a room remodel. $4.00 on Amazon now. It helps to use a right angle drill to power the bit.

Izzy Swan does some interesting stuff, much of it useless. This is an example of that.

Bad Dog tools sells a Forstner style bit that will turn corners.
I've not used 'em but seen the demo countless times.
Here's a video of them in action:

I've got a set of their "normal" drills for drilling into hard stuff, and I'm quite satisfied with them even if they were a tad expensive.
