Questions & Answers

will it cut through nails

will it cut through nails
Asked by: sparky
Yes it will cut through nails. However, doing so will dull the cutting blade. Sometimes pulling the nail isn't an easy option and moving the hole doesn't work. So just drill through them and be prepared to change the blade.

will it drill metallampbost

Asked by: trop
No. The Self Feeding Switchblade drill bit is intended to be used on lumber drilling only. For going through a metal lamp post we suggest using one of our Hole Dozer Hole Saws.

Typically no winding left attached to the material your cutting through. Used with Milwaukee's cordless holehawg and it easily powered through a 2" lvl beam. When it's gets dull, one can replace only the cutting blade; instead of the whole bit. They make 18" auger bits that do the sane thing.

If you don't it gets filled with wood chips, binds and then renders the bit useless. It took me 20 minutes to dislodge the insert. Afterwards, it worked as well as any other bit.

Rated 4 out of 5 by from Great, but buy spare cutting edges. This bit tears through very efficiently. It throws wood chips the size of corn flakes. But as soon as i caught a nail or a hard knot in old wood it needed a new blade. Works well enough, but for the price I hoped for durability more in line with my Milwaukee tools. For new construction Id give it 5 stars. For old work it didn't live up to the brand for me.

Rated 5 out of 5 by from Great Bit Milwaukee has been the standard in self feed bits for decades and that hadn't changed in this new design. Great Self Feed bit!

Rated 5 out of 5 by from Excellent for the chosen task I use this bit to cut finger pull holes for bypass doors. Exact size for finger pulls. Cuts quickly and accurately.
