Milwaukee 2-1/2 in. Carbide Grit Hole Saw with Pilot Bit

Cut Through a 2″ water meter lid just fine. Took about 10 minutes. Works better with water. That was not mentioned on the package. That’s why only four stars.

Worked like a charm to cut holes through tile and green board to install grab bars in a shower. Be sure to use a punch to divot the tile first so the bit doesn’t slide.

Easy to assemble and use. Performed admirably given the task it was used for. We were boring multiple holes in fire brick for use in a forge. This bit did a great job. We did not utilize the pilot bit and had a hole template made of wood for guiding the hole saw, making multiple holes in each brick. Given the number of holes and bricks we only destroyed 1 of the two bits purchased.

Great price- much better than competition. Worked very well. Only four stars because I can’t rate the durability from my experience.I used the bit for one project- to cut through dense laboratory tabletop material (very hard, with sand in it). It cut through 1 inch thickness in about a minute, using only a small cordlless drill, low speed and no coolant. I was enlarging a hole so I couldn’t use a pilot bit. I was able to start the cut without a pilot drill bit, by starting with light pressure at an angle to the surface. This was easier than I expected. Once I got it started, I could gradually tilt the saw up to vertical and increase pressure. It was stable and self guided after that.

just what I needed to run conduit through the stucco wall. nice clean hole.

Drill a 1 !/4 hole in 4″ of cement .Had to keep adding water. Took one hour + hole saw still good enough to do another hole if I need to

USED TO CUT A 2 1/2″ HOLE IN BRICK, USING WATER FROM A PLASTIC BOTTLE W/ A PIN HOLE IN CAP TO LUB THE CUTTING EDGE. NICE CLEAN CUT.

I used this to cut through 3 inches on concrete for some conduit. I used water to try and keep it cool. I had to dig out the concrete from the saw so I could get through the concrete.

I picked up this $10 hole saw to install a removable pool fence in my travertine pavered patio. I drilled 10 1″ pavers with this hole saw, and it did them all without any trouble. It finally gave up and lost its carbide tips when I drilled the last paver which was on concrete. The stones in the concrete were probably too dense. But It did 10″ of travertine, so I can’t complain. I checked out the $40 ridgid hole saw, but went with the Milwaukee just to try, and glad I did. I did have to buy a $14 arbor. Then I figured that I could not go deeper than the length of the hole saw, because that arbor’s diameter was wider than the hole, so I picked up another arbor for $10 more, which came with another standard hole saw. Also picked up a $10 extension. Everything works well together, and looks like it’s made to last. Except don’t expect to go through too much solid concrete. It seems to work very well on travertine and probably ceramics too. I used a heavy duty drill and kept pouring water into the hole as I drilled, so I never let it get too hot. Definitely will buy from the same line of Milwaukee again if I need to drill into stone.

7/8″ carbide hole saw cut through my stucco wall with exact size for 3/4″ diameter pipe and looks like professional work. Used lite streem of water to cool when cutting to extend bitt life. Just don’t understand why this item isn’t stocked in my local Home Depot stores. Seems most common sizes would be 5/8″ 7/8″ and 1 1/4″.
