Irwin Diamond Drill Bit - 12mm

The reverse spiral design helps to force water towards the cutting head, which cools the diamonds, increases cutting speed, and prolongs the life of the drill bit.

Yes, using water is highly recommended. It significantly increases the lifespan of the tool and improves cutting performance by keeping the diamond edge cool.

No, this drill bit should only be used with a standard rotary drill. Using it with a hammer drill can damage the bit and the material being drilled.

The slot is designed to automatically clear the cut material (slug) from the drilling area, allowing for continuous, uninterrupted cutting without the need to manually remove debris.

This drill bit is suitable for fast and smooth cutting in all grades of hard and soft tiles.

The raised diamond grit edge allows for easy starting on hard tile surfaces without the need for a guide, preventing the bit from slipping.

Please refer to the manufacturer's warranty information provided with the product packaging or on the Irwin website for specific warranty details.

Ensure you are using water for cooling. Check that the drill is set to rotary mode only and not hammer mode. Verify the diamond grit edge is not worn down.

Increase the flow of water to the cutting area. Reduce drilling pressure and allow the bit to cool down between holes.

Ensure a smooth start by holding the bit steady. Consider using a tile drilling lubricant. Reduce drilling speed and pressure as you near breakthrough.

This is less common with the auto slug ejection, but if it occurs, stop drilling and carefully use a tool to remove the debris from the spiral slot. Ensure water is flowing to help flush material.
