Extended Product Information
FAQs
Are these bits compatible with a standard cordless drill?
No, these are SDS Plus bits and require an SDS Plus hammer drill. They will not fit into a standard three-jaw chuck.
What is the maximum working depth?
These bits have a working length of 100mm.
Can I use these for drilling into metal or wood?
No, these are specifically designed for masonry, brick, and concrete. Using them on metal or wood will result in poor performance and damage to the bit.
How many bits are in a pack?
Each purchase includes a pack of 10 drill bits.
What should I do if the tip gets hot?
Stop drilling and allow the bit to cool down naturally. Do not quench it in water, as sudden temperature changes can weaken the carbide.
Troubleshooting
Bit slipping or not rotating
Ensure the bit is fully inserted into the SDS Plus chuck until you feel a positive mechanical click.
Slow drilling speed
Check that your drill is set to the correct hammer-drill mode; also ensure the flutes are clear of compacted dust.
Bit getting stuck in the hole
Frequently pull the bit back out of the hole while drilling to clear accumulated concrete dust.

Setup, Compatibility & Care
To ensure optimal performance, insert the bit into an SDS Plus compatible chuck until it clicks into place. Before starting your project, verify that your drill is set to the 'hammer' or 'rotary hammer' mode. For maintenance, avoid running the drill at excessive speeds for prolonged periods, as extreme heat can degrade the carbide tips over time. After use, inspect the carbide tips for chips or wear, and wipe the shaft clean of concrete dust before returning the bits to their storage case to prevent corrosion.
