Decent price for DYI, price gives 5 star.
5 out of 5 stars
Decent price for DYI, price gives 5 star.
Needed to increase two hole size in my porcelain toilet, replacement bolts were all too big. Considering the size, and that it saved buying a new toilet, it was a bargain. I don’t think these would be what you want as a tradesperson. While it did my job, it was too slow for commercial, and I feel like it would not do a lot of holes because the abrasive stuff comes off. However, the self- lobe wax worked better than I thought it would, but I still kept spraying the hole with water anyway. The porcelain was about5/8 inch thick, and there was no chipping on the underside after drilling. Worked perfect w within my expectations. Recommend as a great set for occasional use.

    I had to make 8 holes on tiled wall to install shower glass. The initial gold punch but lasted for 3 holes until breaking. The 6mm lasted for 2 holes before warping from heat. The 5mm lasted enough to make initial groove in the last 3 holes.
    I had to use a concrete drill bit to finish the job, it worked. Concrete drill bit saved me.

    Not much to say other than if you need to drill into hard surfaces for mounting bolts or screws, these should do just fine for you. Used them for mounting a microwave/hood fan in the kitchen onto a Quartz backsplash…worked perfectly. Much less cost than buying at the big box stores.

    Die Fliesenschneider mit den Diamantkronen machen einen guten Job. Es ist ein wenig ungewöhnlich den Bohrer im Loch „herumeiern“ zu lassen, aber das Ergebnis ist wirklich tadellos. Die Fliese wird nicht beschädigt und das Loch ist exakt ohne Bruchstellen. Von mir gibt es eine 100-prozentige Empfehlung und fünf Sterne.
