MARSBASE Diamond Hole Saw Kit 17PCS Drill Bits Sets with Double Suction Cups Guide Jig Fixture from 4mm-83mm Hollow Drill Set for Ceramic, Glass, Tile, Porcelain, Marble, Granite

L'outil fonctionne tel que décrit. La seule raison de ne pas avoir accordé 5 étoiles est la faible durée des trépans. On ne peut pas faire plus que 6 trous, même si on prend bien soin d'utiliser de l'eau pendant le perçage.Plusieurs revues mentionnent que les ventouses ne fonctionnent pas. Je n'ai eu aucun problème avec les ventouses.

Thought the product was great, just what I needed to drill through our granite counter top to install a new faucet. Could not be happier. The suction pads were well strong enough to hold the bit still, they way they fit together on the bit helped hold the bit straight. During drilling the bearings used to guide the bit did not crawl up or down, held steady and true, did not bind. I have seen other systems for doing this but at a much greater cost. The diamond on the bits while nickel plated held well and worked well through the whole 1.5 inches of drilling. Just let the bit and the drill do the work, additional pressure was not needed. Trying would have ruined the bit before the job was completed.

Le gusto mucho

The suction cups did not hold well at all on porcelain tile.I tried drilling using 2 different smaller bits and could not get through a single tile and the diamond was completely worn off the bit rendering it useless.

Great tool for the price, I primarily work with porcelain tile- this tool works great
