About this item
- Diamond Drill Bits: Electroplated diamond is uniform and more wear-resistant. The hole saw achieves high precision and smooth cuts without edge breakage, with good toughness and high strength.
- Wide Applications: Suitable for cutting accurate holes on glass, ceramic, tile, porcelain, marble, stone bottles and pots. Not suitable for drilling tempered glass, plastic and wood.
- Large Clearance Hole: The diamond hole saw with clearance hole facilitates the entry of cooling water and the escape of chips from the drilled hole. Makes the drilling process easier. The cutting is flat and smooth without scratches.
- Features: Diamond coating maximizes performance and retains a sharper cutting edge than traditional carbide or bimetal hole saws. Nickel plating on these bits maximizes your tools life with great resistance to corrosion.
- Tips: Use at low drilling speeds and drilling pressure. Always work with coolant (water) when drilling. Not suited for concrete or depth beyond about 1/2 inch. The hole should be entered smoothly, and no side pressure is applied.

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.
