Questions & Answers

Holes Too Large?

I bought this to drill some 1/2" holes in brick using a Bosch Bulldog rotary hammer. The holes are too large for a lead anchor that requires a 1/2" hole. The anchor just falls into the hole with no resistance and spins. I tried drilling a smaller pilot hole first but the result was the same. I ended up using a 7/16" drill and hammered the anchors in though this is really not the correct way to do this. I was drilling carefully to avoid wallowing out the hole. I hope a Bosch rep sees this post and can advise me on why this drill cuts the hole too large. If this is by design then I feel I wasted my money.

I have had the same experience with masonry bits and normally go one size down from the recommended fastener size due to the size of the carbide tip that most masonry drills use.

No. The carbide cutters are attached to a regular steel fluted shank.

Bulldog 1/2 in. x4 in. x 6 in. SDS-plus Carbide Rotary Hammer Drill Bit is rated 4.0 out of 5 by 122.

My use for this bit was to hammer-drill into brick mortar so as to put in place #10 plastic anchors. I then used #10 stainless steel screws to re-mount the shutters. It will make it easier to remove them the next time. The bit worked flawlessly on the mortar. My one recommendation is to stop the drill bit when it reaches the desired depth. Then pull it out with the drill stopped. If you keep the drill spinning, it tends to widen the hole a little too much for a #10 anchor.
