About this item

- 【Precision design:】The Diamond Drill Bit's side holes help to easily remove waste and also speed up cooling; the surface of the bit is nickel-plated for improved corrosion resistance; and the thick, uniform Diamond Coating Top ensures that fast, hard-wearing drilling can be guaranteed.
- 【CUTTING MATERIALS:】It is suitable for drilling holes in tiles, glass, ceramics, marble, limestone and light granite. Works with most electric and impact drills.
- 【Cutting technique:】Draw the cutting position with a marker, drill slowly at a 45° angle, wait for the groove to appear, then drill slowly and vertically with a hole saw. Diamond drills do not have a centre point, so start from the edge when drilling.
- 【Kind Tipps:】When cutting, be sure to constantly refill the hole saw with water to avoid premature wear of the material being drilled and the tool, while drilling at a slow speed. This will extend the Lifespan of the diamond drill bit.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
