Is a pilot hole necessary when using turbo screws in soft or hardwood?
Hi Mr Bezuidenhout
The Turbo Screws have a Type 17 cutting point to cut into wood. This will eliminate the need for pilot holes into soft & hard wood. For precision work, it is recommended to drill a pilot hole on hard wood when you use thicker screws (4.5mm-5.5mm) or when you work close to the edge of the wood to prevent the timber from splitting.
