Review: Perfect for hard rock. - I bought the 8mm bit as I have a gate that requires fixing to a stone wall. The drill bit performed extremely well and bored a perfectly round hole the full length of the bit. It's always worth paying a little more for tools if you want a hassle free job. It drilled into hard rock without overheating, unlike a standard masonry bit. Well worth the price.
Review: Wow, these drill bits fantastic - I brought 4 of these because some of the reviews said they were not that good. Well I tell you now I am pleased that I did, not only did they preform extremely well but I only used one drill bit to drill 9 not 1 but 9 holes into an old flint stone building for a support bracket. To say I’m pleased and happy is without a doubt an understatement.

## Features

- Cylindrical tip made of ground steel that allows great stability when drilling.
- The 4-cutting edge tip allows you to create perfectly circular holes with more ease, precision and speed.
- Plate made of HVA 1650 tungsten carbide with a 130° angle, resistant to high temperatures. Plate brazing at 1000 °C.
- More comfort when using the bit and longer duration: the “U” geometry of the 4 spirals allows the removal of large volumes of dust, generating less vibrations and less friction when drilling.
- 4-cutting edge wall drill bit suitable for common household drills with cylindrical attachment. A professional drill with an SDS adapter is not needed.
