80mm Diamond Coated Glass Hole Saw – Cuts Ceramic, Tile, Marble, Porcelain & More

Need to drill clean holes in glass, tile, or stone?

This 80mm diamond-coated hole saw is built for the job.

The AAA-grade diamond particles give it sharp, fast cutting power, while the nickel plating adds durability.

It’s perfect for ceramic, porcelain, marble, brick, and similar materials – but not for tempered glass, wood, or plastic.

Remember to use it at low speed (800-1000 RPM) and always keep it cool with water or coolant.

Start at an angle to create a guide groove, then drill straight.

The side holes help with chip removal and cooling.

Get smooth, precise holes without chipping edges!

This hole saw makes tough drilling tasks much easier.

The diamond coating stays sharp longer than regular bits, and the design reduces vibration for cleaner results.

Always use lubrication – without it, the bit can overheat.

It’s great for DIY projects like installing taps, vents, or pipes in tiled walls or stone surfaces.

The 80mm diameter (about 3.15 inches) is ideal for larger openings.

Shank size is 10mm, compatible with many drills.

Whether you’re a hobbyist or a pro, this bit saves time and delivers professional-grade cuts.
