The Easy Coupling makes these perfect for use in a drill, they will even lock in to driver bits to extend the length of the drill bit to reach awkward areas.
Can comfortably drill 20 or more holes in the hardest grade 5 porcelain.
Allow the drill and the rotation to cut the hole, don’t lean on these bits like you would a masonry drill.
Never use the hammer action it will destroy the diamond tip. Use at around 2000 – 3000rpm. That’s generally that fastest speed on a drill driver.
Sizes 6mm to 14mm are wax filled. 16mm, 18mm & 20mm are not wax filled. We found at these larger diameters the core tended to get stuck in the wax.
The boxed set gives you 8 drill bits, one of each size.
