The Irwin Granite drill bits are designed for professionals and serious DIYers tackling very hard materials like granite, concrete, and natural stone with impact or percussion drills. Their key benefit is significantly increased hole drilling capacity and accuracy compared to conventional bits. A potential caveat is their specialized nature, meaning they may be overkill for softer materials.

These bits are specifically designed for very hard materials such as granite, concrete, brick, and natural stone.
While they can be used in a standard drill, they are optimized for and perform best with the impact/percussion function of a hammer drill or rotary hammer.
Irwin Granite drill bits are designed to be more robust, drilling up to 40% more holes and producing 50% more accurately sized holes in hard materials compared to conventional masonry bits.
Clean off dust and debris after each use and store them in a dry location to prevent rust or damage to the carbide tip.
The rounded cutting edges enhance durability and contribute to drilling more accurately sized holes, which is crucial for precision work.
No, these bits are specifically engineered for masonry and stone. Using them on wood or metal can damage the bit and is ineffective.
Ensure you are using the percussion/hammer setting on your drill. Verify the drill bit is securely clamped in the chuck. Check if the material being drilled is too soft for this specialized bit.
Reduce drilling speed. Ensure you are not applying excessive downward pressure. Check for hard inclusions within the material being drilled.
Periodically withdraw the drill bit from the hole to clear dust and allow for cooling. Do not force the bit; let the drill and bit do the work.
Setup: Ensure the drill bit is securely fastened in the chuck of your drill. For optimal performance, use the drill's hammer or percussion setting. Select the appropriate speed setting for the material being drilled.
Compatibility: These bits are designed for use with standard rotary hammer drills and impact drills that feature a percussion function. They are intended for use in hard materials such as granite, concrete, brick, and natural stone.
Care: After use, remove any dust or debris from the bit. Store the bits in a dry place to prevent corrosion. Avoid using them for prolonged periods at excessive speeds in softer materials, as this can lead to premature wear of the carbide tip.
