Klein Tools 53718 9/16-Inch By 54-Inch Flex Bit Auger With Screw Point

Nice quality tool, I’ve run about 30 holes so far and still working perfectly. Nice that you can use it to pull from either side of the bit due to holes on both ends!

Pratique

Drilled through the wall header like butter. The bit has 3 flats to prevent slippage. I did not hold the trigger full blast but eased on it to prevent any sudden torque and it worked well. I used it in conjunction with one of those locator ball things to center the hole. Suggestion: get the longer bit. The 54 inch was just barely long enough to reach from a switch box hole through the wall header plate.

Ordered a used 9/16-Inch x 54-Inch Long bit and received a 1" diameter instead. The bit received works well and arrived in good condition, but no time to exchange it and now have massive holes to caulk. No explanation; seems a bit suspicious on the fulfillment end.

I was a little hesitant after reading some reviews but this drill bit is a beast! Chewed thru the wood like nothing. Had a nice flex to it, don’t apply to much pressure and let the bit do the work!
