FAQs:
1. What materials are the Werkstein diamond drills suitable for?
- They are perfect for hard materials such as glass, ceramic tiles, stoneware, granite, marble, limestone, quartz, terracotta, terrazzo and many more.
2. How high should the speed of the drill be when drilling?
- In principle, the highest possible speed is important to ensure a long service life of the drill bits and to achieve good drilling progress. Therefore, a (corded) drill with 2000 - 3000 rpm should ideally be used for the drill bits.
- When using a cordless screwdriver, we recommend a speed of at least 1600 rpm.
3. Does cooling have to be used during drilling?
- No, it is not necessary to cool the drill bits, as they are equipped with cooling wax inside. However, it can increase the life of the drills.
4. How are the drills used?
- First, pre-drill a hole with the golden carbide bit. Caution: This is only used for spot drilling and is not suitable for the entire drilling in hard materials!
- Then insert one of the included diamond drills and continue drilling the hole. It is important that you make slight swiveling movements during drilling. This ensures an ideal drilling result.
5. Are the drills compatible with my machine?
- Thanks to the exact hex shank size of 6.3 mm, you can use our drill bits with commercially available drills and cordless screwdrivers of many well-known brands. This is ensured by manufacturing according to the best possible standards.

Drilled holes in very hard porcelain tile without difficulty. Durability remains to be determined. Initial performance suggests this is a quality set.

Advised by builder to use this type of drill to bore through hard sandstone coping stones to avoid damage to mortar joints. These drills were great, went through easily. I did purchase extras as I had 24 holes to drill expecting to get only a few holes from each drill. I was careful not to overheat the drills and used a few. None have burnt out and are still useable.

This product worked very well. It exceeded the ones I have from Alpha and Milwaukee. Went through ceramic tile as if the tile was butter.

Spade bit didn't last 5 holes before it quit! Went local to get another one. I only had 12 holes to drill for two grab bars.

I bought a set to drill some really expensive ceramic tile. As you can see from the picture. They do work. Drilled effortlessly right through. Didn't chip or crack my tile. I'd highly recommend!
