Worked fine. I use it to pre-drill holes to sink orange fiberglass snow markers into the ground so they are deep enough to stay upright. Helps a lot on frozen ground.
Pros
Asymmetric diamond cut tip Carbide tip - allows for an accurate start
These *could* be great if they were the right size. The handle is 3/16, not 1/4 as advertised, which means it's too small for my drill (BLACK+DECKER BDCDMT120IA, 20V Matrix Drill and Impact Combo Kit).
Pros
Designed for impact work - fast drilling in block, masonry and concrete
