Frequently Asked Questions | FAQs
When should I use a 7mm SDS plus drill bit?
Use a 7mm SDS plus drill bit when operating a heavy-duty hammer drill on dense materials like concrete, brick, and blockwork. The specialised shank design allows the bit to slide back and forth, maximising the impact force and preventing slipping for fast, efficient drilling on busy construction sites.
What are the benefits of a 7mm cobalt drill bit?
Cobalt drill bits provide exceptional heat resistance, making them the ideal choice for boring into highly abrasive and hardened materials like stainless steel or cast iron. They are perfect for heavy-duty, continuous use, as they maintain their cutting edge for longer than standard HSS bits.
Can I use a 7mm multi-material drill bit for bathroom fittings?
While a multi-material bit can cut through ceramics, a dedicated 7mm diamond or tile drill bit is a much safer choice for glazed surfaces. These bits feature a specially designed carbide tip that pierces hard tile without wandering, cracking, or shattering the surface, ensuring a clean and secure fit for your fixtures.
