Review on 🔩 Bosch TC700 Masonry Screw Grip by Victor Olsen

Bosch TC700 Masonry Drill Bit Holder. These drill holders are amazing! Just the right thing to keep the drill from slipping in the drill chuck. The holder comes with a hex wrench to tighten the set screw that holds the drill bit in the holder. The only downside is that the shank is not 1/4" as advertised by Bosch. I bought a holder specifically for my DeWalt impact wrench (which of course has a 1/4" chuck). The holder shaft is actually 8mm long. This fact does not detract from the usefulness of the holder, but using a drill with a 1/2 inch chuck does introduce some inconveniences. . It would be great if DeWalt offered a drill holder like the TC700.BTW for those interested, the holder does not drill holes. It just keeps the drill perfectly still in the drill motor.
