🔩 Choosing the Right Drill Bit for Cladding Installation
Selecting the correct drill bit is a small decision that can have a big impact on installation quality, drilling accuracy and long-term façade performance.
In the latest addition to our Knowledge Base series, we explain the differences between HSS, Cobalt and Carbide drill bits and when each should be used in cladding and façade applications.
Key takeaways:
✔ HSS drill bits are suitable for aluminium, timber and light gauge steel applications
✔ HSS step drill bits allow installers to drill through subframe and cladding in a single operation
✔ Cobalt drill bits are the preferred choice for stainless steel due to their superior heat resistance and durability
✔ Carbide drill bits are ideal for fibre cement panels and other dense or abrasive façade materials
Using the right drill bit helps achieve cleaner holes, reduce the risk of panel damage, support correct fixing performance and minimise material waste.
