Customer Reviews for Milwaukee 3/8 in. x 10 in. x 12 in. Carbide Hammer Drill Bit

One of the best cordless rotary hammers I have ever used Cannot go wrong with Milwaukee

Was used to drill blue-stone after carbide tipped bit failed. Cut thru like butter, would definitely recommend.met my expectations without a doubt.

Was dull and useless after 1.5 holes of about 3 inches

made 6 cuts and the tip was ground down to uselessness.

this baby chewed thru the concrete like it was swiss cheese!

The Carbide tips broke and worn off after one hole. Drilling through concrete on the second hole took a long time. The Bosch bit we had did not loose or wear out its carbide tips on the same concrete.

These hold up very well.

Bit worked great in brick mortar joint.

Vert strong ripped through the concrete welll

Worked well drilling several holes through 4 inch pour concrete and still seems as sharp as when I drilled the first hole

Fast drilling with very little wear on the bit after use.

Recommended by Home Depot staff but not compatible with the drill purchased.

Milwaukee is usually known for quality tools, but these bits must be defective. At over $14 a bit, it took me three bits using a hammer drill to get through concrete that contained no rebar, I know because I poured it myself! The only way I got three 2 inch deep holes drilled, was by first drilling with an old Bosch 1/2” carbide bit and then coming back with these awful bits and eventually bludgeoning the holes to 5/8”! It isn’t that they were dull, they would just chip and shatter so that there was actually not cutting edge. The second hole I tried to drill only got about 1/4” deep and stopped producing dust…I looked at it and it was missing almost 2/3 of one cutting edge. Stay away from these brittle pieces of junk. By the way, Home Depot saw the bits and promptly refunded my money…excellent customer service…thanks!

The drill bit worked great

2 holes in a 8” concrete wall was all they would do.
