Thread: Electric (corded) hammer drills
10-25-2012, 10:18 AM #14Update... finally had time to do some online research... came across this item:
Anyone have experience with this drill?
THX in advance for any posts.
Still no comparison to a spline drive or hex shank rotary hammer.
If you plan to cut through 4" of concrete more often, or want to cut 4-1/4" holes in concrete with a percussion coring bit, then you want spline drive.
