MuZuZiDiamond Bit Marble Cutter Stone Tiles Concrete Hole Saw Hand Drill Hole Tool 6-60mm (50mm, 1pc)

Used to cut 9 25mm diameter holes in 22mm thick Indian Sandstone. The first bit snagged after about 10mm in the first hole and split away about 1/3rd cutter face (including one of the two vertcal grooves that do the cutting (possibly as the drill was not vertical and stead - happened very quickly). Managed to use the other drill to cut a start of about the 8mm and then use the half broken drill to compplete the holes (thinking it would at least cut a little more). In fact this comination drilled all 9 holes! Used plenty of water and plunged the drill into a bucket of water every10 -15 seconds or so.Having to go carfeully meant the drilling was slow. The OK bit looks fine still and could drill more holes. Having broken one and then trying limp to complete the job, was stressful. In hindsight I would have bought 2 packs of 2 for peace of mind, but may have neded up with barley using the second pack.Good product if you go slow and keep cool.

Cheap tile cutters that clear themselves, but 1 in 3 will snap at the head..... I use them in construction as they make my job quicker for less cost.

It is a berry good cutter

Very good and good value for the money

I am impressed. A good self-clearing design with fast drilling speed, even in hard stone like marble. They seem very durable as well. I bought several and I doubt I will wear the first one out any time soon. After several holes it is still drilling as fast as ever. I wish Muzuzi would do boxed sets, as I would buy one!

I sent it back because it bust I want a refund

This tool did the job- cutting a 30mm hole into a 2 inch thick Indian Sandstone patio slab with a core drill. Very happy.

Worked a treat in drilling holes in slabs in order to insert bird feeder poles.
