I've been using Wood Owl augur bits, which work incredibly well for drilling large holes in wood without needing power tools. At my makerspace for kids, I prefer hand tools for their safety and ease of use for beginners. However, I faced challenges finding a bit brace that could handle these hex shank bits, as most are designed for older styles that don't withstand torque effectively. After some experiments (and a few ruined tools), I've come up with a reliable combination: using a specific bit brace that ends in a 1/2-inch square drive and attaching a strong Jacob's chuck to it. This setup allows me to use modern hex drill bits effectively, even at high torque, without any slipping or breakage. If kids struggle with large augur bits, I can switch to a square T-handle or breaker bar, making it easy to drill through tough wood without worrying about the tool failing. What do you think?

I've had good luck using a 1-1/8" Wood Owl auger with a 3-jaw chuck brace from Seleron to drill through thick red oak. My main concern was just having enough strength to turn the bit rather than it slipping. What size augers are you trying to work with?
I used that bit for my roubo bench mortises in ash! It was tough, but definitely a workout!
If you’re looking for versatility, there are two-jaw shank to hex shank adapters that can work with vintage braces. I’ve seen good options that enhance usability without switching to new production braces that often disappoint.
From my experience, most newer production braces just don't compare to vintage quality tools. You can get a Yankee 2100 or 2101 brace, which handles hex bits like a champ without breaking the bank. They're way better than the new ones!
I’ve got a couple of vintage drill bit braces, like the ones made by Dunlap and Keen Kutter, which can handle both twist bits and augers. They work like a charm! Newer tools can be hit or miss; I'm always happier with reliable vintage gear.
Totally! I have a similar vintage brace, but I've found that hex bits tend to slip if there's too much torque.
I think the Seleron brace is great for up to 1.25" bits. Beyond that, you might need a more robust Scotch auger.
