Drill bits engineered for impact drivers with a ¼” hex shank. If you own an impact driver, these will be handy to drill holes through the plywood so as to install the t-nuts.

Diameter: 12mm or 12.5mm
- 12mm required for all round based t-nuts,
- 12.5mm required for the rectangular and diamond shaped industrial t-nuts.

Ideal for use in timber, plastic, ferrous and non-ferrous metals.
