Irwin Diamond Drill Bit - 8mm

No, a standard variable-speed drill is sufficient. Ensure the drill is not set to hammer mode, as this can damage the tile and the drill bit.

The lifespan depends heavily on usage, material hardness, and adherence to lubrication (water) and cooling recommendations. Proper use can yield many holes, especially with consistent water application.

While designed for tiles, it may be effective on glass. However, always use water and a very slow speed, and test on a scrap piece first, as glass can be more delicate than tile.

The reverse spiral flute is designed to force water towards the cutting head, which cools the diamond grit. This enhances cutting speed and significantly extends the life of the drill bit.

The raised diamond grit edge helps with initial starting. For extra security, you can create a small pilot indentation with a center punch or firmly mark the spot with a pencil before drilling.

This bit is specifically designed for tiles. For concrete or masonry, you would need a masonry or concrete drill bit.

After use, clean the bit of debris and allow it to air dry completely before storing. Avoid storing in damp conditions.

Ensure you are using water to cool the cutting head. Reduce drill speed and apply consistent, light pressure. Check that the drill is not in hammer mode.

Ensure you have a firm grip and are starting at a slight angle before bringing the bit perpendicular to the surface. The raised diamond edge should aid in starting; if not, mark the precise starting point with a pencil.

Ensure the auto slug ejection slot is clear of debris. Slightly retract the bit during drilling to help clear the slug, especially in thicker materials.
