ANCHOR SET TOOL |
摘要 |
A tool adapted for use with a drill for installing screw anchors in concrete or masonry walls or the like having a sleeve type body, a bit holder slidably located in the body, a drill bit with a handle secured in the bit holder, a coil spring seated on a collar of the bit holder and extending around the bit, and a nut driver secured to the front end of the body. The bit holder is adapted to receive the bit handle and to also serve as a stabilizer for the bit and the coil spring. The nut driver is formed to guide the bit and to shield the front end of the bit from contact with drive members that may be secured in the nut driver. |
