About this item
- 【Material:】 Carbon Steel and Diamond coating, perfect for drilling glass, ceramics, tiles, bottles, block jars, porcelain, granite clear stone.
- 【10Pcs higher quality, longer-lasting Hole Saw Bits : 】6mm, 8mm, 10mm, 14mm, 16mm, 18mm, 22mm, 35mm, 40mm, 50mm.
- 【WELL DESIGNED: 】The Diamond Drill Bit's side holes help remove waste easily and also speed up cooling; the surface of the bit is nickel-plated for improved corrosion resistance; the thick and uniform diamond coating ensures fast, wear-resistant drilling.
- 【Cutting technique: 】Draw the cutting position with a marker pen, drill the hole slowly at a 45° angle, wait for the groove to appear and then drill slowly and vertically with the hole saw. Diamond drills do not have a centre point, so start from the edge when drilling. You can refer to the video or ask us.
- 【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.
