wolfcraft Annular Bit, Tungsten Carbide Tipped, with SDS Plus Mandrel I 5480000 I for Electrical and Plumbing installations in Concrete, Brick Walls and Stone; Cutting Depth 46 mm

I would have given this a 5* if you could change the centre guide bit, but for some reason the manufacturer chose to make it non-removable! Most concrete coring bits have a centre bit secured with an Allen key that can be replaced when worn … this doesn’t!Apart from that, the quality is first class and vastly superior to the cheaper Far East options.

Was perfect for the job of drilling a hole in the garage for a 32mm waste pipe for the washing machine.Also had to cut into a single brick with out the brick breaking. Warning it is a long job if you are new to this. Also would recommend watching video on You Tube before using if it is the first time you have used one of these cutters

Excellent product, does the job. The Amtech extension bar is shown as "bought with' - it isn't compatible !!! Do not buy together.

Very easy to use, did its job with ease.

Did the job easily for the price I paid.No idea why you would have to spend more when this item easily achieved what I wanted

Not long enough to go through a double wall but cuts well

no good on hard stone

works great did loads of holes stll going
