Irwin Granite Drill Bits - 8.0mm X 120mm

This drill bit is specifically designed for very hard materials such as granite, concrete, and natural stone.

While it might cut softer materials, it is not optimized for them and will wear down much faster. It is best used for masonry and hard stone applications.

This bit is designed for use with a hammer drill or rotary hammer drill, preferably in percussion or impact mode, for optimal performance in hard materials.

The extra-hard, thicker carbide tip is more robust, allowing it to withstand the stresses of drilling hard materials more effectively, leading to increased durability and more holes drilled.

Rounded cutting edges make the bit more resistant to chipping and wear, extending its usable life and ensuring more accurately sized holes are drilled over time.

The Irwin Granite drill bit is designed to drill up to 40% more holes than conventional masonry drill bits in hard materials.

Please refer to the retailer or manufacturer's website for specific warranty information, as it can vary.

Ensure you are using the percussion/hammer drill mode. Verify the drill bit is securely tightened in the chuck. Check if the drill bit is damaged or excessively dull.

Allow the drill bit and drill to cool down periodically. Use a consistent, steady pressure rather than excessive force. Consider using a lubricant or water for cooling, especially when drilling deep holes.

Ensure the drill bit is the correct size for the intended fastener. Check for excessive wear on the cutting edges. Use a consistent drilling technique.
