Frequently Asked Questions | FAQs

What are 13mm flat wood drill bits used for?

A 13mm flat wood drill bit (often called a spade bit) is used to quickly bore relatively large, flat-bottomed holes through timber, plywood, and chipboard. Their wide, flat blade and central point make them ideal for creating clearance holes for pipes and cables during electrical or plumbing installations.

Can I use a 13mm multi-material bit on masonry?

Yes, multi-material drill bits are designed to cut through a variety of surfaces, including masonry, wood, and plastic. However, if you are working with particularly dense materials like concrete or stone, a dedicated masonry bit or SDS plus bit might provide better performance and longevity.

What makes an HSS titanium drill bit different?

HSS (High-Speed Steel) titanium drill bits are coated with titanium nitride, which significantly increases the hardness of the bit and reduces friction. This makes them highly effective for drilling into tough metals, as they stay sharper for longer and can withstand higher temperatures than standard HSS bits.
