Irwin Diamond Drill Bit - 10mm

Yes, using water is highly recommended. It cools the diamond tip, extends the bit's life, increases cutting speed, and helps create cleaner cuts.

No, this diamond drill bit is designed for use with standard drill settings (rotary only). Using the hammer function can damage the bit and the material being drilled.

It is designed for hard and soft tiles, glass, and other brittle, hard surfaces. It is not intended for use on wood, metal, or masonry.

The raised diamond grit edge is designed for easy starting on hard tiles without needing a guide. Hold the drill steady and begin at a moderate speed.

Lifespan depends heavily on usage, material hardness, and adherence to proper techniques (especially water lubrication). With correct use, the tough brazed diamond grit provides long life for its intended applications.

This slot helps to automatically eject the material cut out by the bit (the slug) after drilling through, allowing for continuous and uninterrupted cutting without needing to manually clear the bit.

Ensure you are using adequate water lubrication. Check if the diamond tip is worn or damaged. Increase drill speed slightly if appropriate for the material, but avoid overheating.

Immediately stop drilling and allow the bit to cool. Increase the water flow significantly or take a longer break. Ensure you are not drilling too fast.

Start drilling at a slower speed and increase pressure gradually. Ensure the drill is not set to hammer mode. Use a tile drilling guide for initial stability if needed, though the raised grit should aid starting.

Stop drilling and carefully remove the slug from the auto ejection slot. Ensure the bit is not angled excessively during drilling.
