Overview
A corded rotary hammer pairs a drilling motor with a hammering mechanism so a bit can break through brick and concrete as it turns. This one runs on household power, has variable speed with three settings, and a plastic housing.
Mains power and a hammer action are the reason to choose it for masonry anchors, since the motor does not fade like a battery. The limitation is that impact energy and the bit holder system are not listed.
Who it's for
Electricians, plumbers and deck builders who drill into masonry will use the hammer action and the wall power. Demolition crews and anyone off the grid need a larger or cordless machine.
Pros and cons
- Corded power without battery fade
- Variable speed with three settings
- Hammer action for masonry
- Metal drilling capacity listed
- Impact energy not listed
- Bit holder type not named
- Included accessories unclear
Performance notes
A hammering mechanism delivers impacts along the bit axis while the bit rotates, so masonry fractures ahead of the cutting edge. Steady pressure and a sharp bit decide how fast a hole advances. Variable speed lets the user start a hole slowly to avoid wandering and then speed up.
