Simple, tough and built for fast, clean holes in timber, the SDB35 35mm Flat Wood Spade Bit is ideal for electricians, plumbers, carpenters and DIYers who need reliably round holes for door locks, wiring, pipe runs and general joinery. Precision‑ground centre point and chamfered cutting spurs deliver accurate starts and reduced tearout for neat finishes in soft and hard woods alike.
