HIGHDRIL 2Pcs Diamond Core Drill Bit,Diameter 32mm Vacuum Brazed Hole Saw for Concrete Granite Marble Glass Porcelain Tile Masonry Brick,Triangle Shanks

I needed a 30 mm hole saw bit to cut two 30 mm holes into my bathroom tiles so that I can put a tap connection through the wall. There were 2 bits supplied in the pack. The one 30 mm bit did the job very easily and quickly. But remember that when you start to drill then have the drill bit at 45 degrees first and when a small cut has been made then gradually lift and level the drill off until the drill is at 90 degrees to the hole which is being cut. Very pleased with the quick and clean cut.

Great drill bits for both porcelain & ceramic, Does the job well & get plenty of holes out of them before needing to replace, Well worth the price paid.

Used to cut through external wall managed without any problems whatsoever even though I was using a cordless drill ...good value for money only used 1 that is still usable for a few jobs yet

Does what it says Good product

Good quality bits. If kept well lubricated with water, they can drill many holes in porcelain tiles. I used an offcut of ply with a hole drilled to the same diameter and kept refilling the well with water to keep the bit cool and lubricated.

These are great I needed them for making a hole in single skin brick work. The diamond tips makes short work of the brick to make them last longer just dip the tip in some water to get rid of the dust and to cool it down. The fact you get two is good but I only used one and it’s still going well the delivery was fast I highly recommend these.

I needed something to cut 32mm holes out of Bricks. Tried a few drill bits but they broke the bricks. But this Drill Core went through with absolute ease. Made a template with a bit of wood so it’s easy to start the core bit on the brick. Kept the water running on it whilst cutting. Would definitely recommend this drill core

Was able to cut through single skin wall with ease, stopping every 6mm of depth to rinse clogged dust off cutter in a bucket of water.Well worth the money.
