Bosch DSBE1012 12 In. Daredevil® Spade Bit Extension

I don't always need a 4-5 foot spade bit for a project. This extension works well to add just a little extra length to get through thicker walls. It works well, but you need to make sure you tighten it enough, or you might lose your bit.

Name brand, high quality, its universal fits 1/4 shank.

I purchased this due to the amazing deal Amazon was offering at the time for six dollars. I had hoped it would also be large enough to fix the larger hex shanks on circle hole cutters however it is not. This will however fix your paddle bits, any standard hex bits for drilling. Still a great addition to the toolbox and glad I picked one up. Very sturdy steel, made by Bosch so can’t be all that bad, right?

This was awesome and I tested the hell out of it... I used forstner bits to bore into maple trees and fir beams, probably 15" per hole and maybe 24 holes I used curtain rod as dowels to secure my treehouse to its foundation 20' in the air in a maple cluster I benched off high.One little trick you might not think to try, I modified one of my round drill bit tails with a small dimple to grab the set screw so that I would not lose it deep in a hole and it would bite better.An ounce of prevention is worth a pound of cure.

Order wrong item, but I kept, with maybe use down the line. Built well.

Great product, great price. Already used and worked well.

Design and construction good but the shaft is not straight. There's a very obvious wobble during operation. Would buy again if I could be sure the next one would be better in this respect.

Works great!
