1/2" Combo Drill Bit for installing Lead Anchors for Sidewalk Bolts in Masonry

Drill bit wore out in 30 holes. WindStorm Products reply: We reached out to two of our storm shutter contractors that purchase from us weekly. The first contractor indicated that he gets between 200 to 250 holes before the bit “slows down”. The second contractor reminded us that he does larger homes and he just plans on a new bit for every job. Both contractors indicated the drill bit works perfectly up until the moment it hits steel in the wall and then replacement is necessary.

I had been trying to install anchors for storm shutters using two drills, and was having problems with alignment and relative depths of the two holes. This drill bit solves that problem, set it up once for the correct offset and drill away

I actually used them to secure a gazebo on my pool patio here in Massachusetts.
