TerrassenFix® Countersink BS

TerrassenFix® Countersink BS is a specialised pre-drilling and countersinking bit. This accessory is a significant time saver on site, and is recommended for giving the best possible flush finished screw detailing. The brad point drill bit allows for accurate positioning, while the integrated countersink and depth stop gives accurate and repeatable bore holes every time.  The TerrassenFix® BS is designed for use with Russwood’s range of Sihga screws, with shank diameter of 5mm.
