    • Lousy from day one.

It didn't have the PH attachments and the counter sink doesn't work. The bits always slide no matter what you do and now the Allen locks are stripped from constantly having to tighten them.

Final review: I freaking hate this thing every time I use it. It’s slow; it’s inconsistent; and I’m looking to replace it. Save your money. Edit: second review after replacing the broken 1/8” bit from the first review. The new drill bit is from Bosch and works well but the actual countersink cutters on the unit do not cut well. They’re quite slow which will be annoying if I need to countersink a lot of holes. I much prefer my Amana and wouldn’t have switched if I hadn’t dropped the Amana and broken the drill bit. Would not buy this product again. The very first hole I drilled broke the 1/8” bit. This was drilling into two layers of 3/4” ply; it wasn’t like I was ramming into a 4” block of ipe or something. Chucked up the 9/64” and that did the trick but not a great first impression. Hopefully it’ll hold up ok going forward. ... show more

When this arrived I was happily surprised that it appeared to be so well designed and of good quality. Unfortunately two drill bits snapped prior to the completion of my first hole. Inferior metal alloy.

Bought and had not used during 30 day return window. Countersink shipped in the housing was stuck in the housing and could not be removed to use other countersink sizes. Obvious bad machining and force press fitted by machine. Poor quality, cheaply made, do not buy.

Don’t waste your money. The cutter is dull after cutting just a few holes and the collar will not stay put. Total junk!
