Irwin Diamond Drill Bit - 5mm

No, a standard drill that can operate in a rotation-only mode (without hammering) is sufficient. Using a variable speed drill can also be beneficial.

The reverse spiral design helps to channel water directly to the diamond cutting edge. This cools the bit, increases cutting speed, and significantly extends its operational lifespan.

While primarily designed for tiles, it may be used on glass with extreme care and ample water cooling. However, specialized glass drill bits are recommended for optimal results and safety on glass.

Sufficient water should be used to keep the cutting area and the bit cool. A continuous slow drip or periodic spraying is generally effective. The water also helps flush away dust and debris.

The lifespan of the diamond grit depends heavily on the material being drilled, the drilling technique, and consistent use of water for cooling. With proper care, it is designed for long-term use on appropriate materials.

This refers to the slot on the side of the drill bit that helps to automatically eject the cut-out piece of material (the slug) from the hole, allowing for continuous drilling without interruption.

Ensure the drill is set to rotation-only (no hammer mode). Verify that sufficient water is being used to cool the cutting head. Check if the tile material is exceptionally hard and may require a slower drill speed.

Increase the flow of water to the cutting area. Reduce drilling pressure and speed. Allow the bit to cool down periodically.

Ensure the auto slug ejection slot is clear of debris. If it's clogged, carefully clear it with a small tool. Continue drilling with adequate water flow to help flush debris.

Consistent use of water is critical for prolonging the life of diamond grit. Ensure you are not applying excessive force, which can damage the diamonds. Consider if the material being drilled is outside the recommended scope for this bit.
