The Trend 5 Piece Quick Release Countersink Set is a versatile countersink kit designed for fast, clean pilot hole drilling and countersinking in timber, fibreboard, and chipboard. Each countersink in the set features a 1/4 inch hex quick release shank, making them immediately compatible with quick-change chucks and impact drivers — ideal for carpenters and joiners who need to switch bits rapidly on site. The adjustable drill bit allows you to match the drill depth to your material thickness, helping ensure a consistent, professional result every time. The tool steel (WS) body is case hardened for extended service life, while the High Speed Steel (HSS) drill bit maintains cutting performance through repeated use. The countersink geometry ensures screw heads sit sub-flush for a neat, clean finish. The set can also be used to counterbore deeper holes for timber plugs where a flush surface is required. Covering screw sizes from No.4 to No.12 depending on timber type, this five-piece set provides the range needed for most joinery and woodworking tasks in a convenient, organised kit.
