Dry Diamond Core Drill Bit Set,BRSCHNITT 2pcs/pack 25mm Diamond Hole Saw Core Drill Bit with Triangle Shank for Porcelain Tile Ceramic Stone Granite Marble

Was surprised how well they cut tile, I did make a jig to keep it steady while drilling,but it did a great job on normal bathroom tile.

Woow

I needed to drill a hole in some UPVC but without using an arbor type hole saw. This item was perfect for that use. However, it is designed for much tougher material but I have no experience of drilling that.

Ordered this to try and make a hole in a 38mm stone paving slad , glad I bought it , it easily cut through the slab with the use of water to cool it down , went through in a matter or minutes (did have to tap with a hammer as didn't go all the way through , about 1mm short) .. did not loose any of the diamond coating so not a single use item .. Only problem is it's tricky to get started ... but once you do it's a great bit of kit and great valve for money

Bought these to drill two radiator pipe holes in ceramic tile. It worked, was slow going and I used up both bits. Don’t use these dry, wet they worked. As a cheap way to drill a couple of holes they worked, not recommend for more serious use than that, I wouldn't expect to get more than one or two holes max per drill bit.

Great product. Cut 10mm porcelain tile quickly and cleanly. Needed for only on whole so a bit expensive for one use, but has plenty of life in it still

Brillant tool for cutting small paving slabs

Drills very quickly

These are excellent value. Drilled through porcelain like butter. If I had one minor complaint it would be that they could do with 4 slots for removing the core after drilling rather than just 2, but I don't feel this is significant enough to reduce rating. So much better value that store-bought alternatives.

Tolle Qualität! Nachdem ich große Probleme hatte in Feinsteinzeug ein sauberes Loch zu bekommen, hat es mit dieser Behrkrone super funktioniert. Nach einem Loch noch ohne sichtbaren Verschleiß. Tipp: ich habe ein Brett mit 25 mm Bohrung auf die Fliese geklebt und hatte somit eine Führung und einen kleinen Sumpf für die Kühlung mit Wasser. Die Drehzahl sollte nicht zu hoch sein und die Behrkrone kann beim Bohren etwas schräg, kreisend geführt werden 😉👍

Hice un par de agujeros en piso de porcelanato

I learned a trick from a friend. Cut a same size hole in a thin piece of wood. Clamp the wood directly over the place you need to drill in the granite. This made the starting of the granite hole very easy with no wobble. The bit cut smoothly through the granite.

Magnifique et de bonne qualité
