Advantages

Each bit in the 25-piece set is manufactured to provide uniform cutting geometry for predictable drilling behaviour and reduced walking at the start of the drill cycle. The set offers good durability for routine tasks and comes with a storage solution that protects bit tips and makes transport easier. Compatibility with standard drill chucks ensures straightforward installation and interchangeability between tools.

How to use

Select the appropriate bit size for the required hole, insert the bit into a properly rated drill chuck and tighten securely. Use steady, perpendicular pressure and an appropriate speed for the material being drilled. For harder materials, reduce speed and apply controlled feed to avoid overheating the bit. Withdraw the bit periodically to clear chips where necessary and allow the bit to cool on extended runs.

Usage recommendations

Wear suitable eye protection and follow standard safety practices when drilling. Match drilling speed and feed to the material, and replace bits when wear or dullness reduces cutting performance. Store the set in its organiser case to maintain bit condition and size order.
