Overview
The Frost 3 Piece Countersink Set includes 12mm, 16mm and 19mm high-speed steel bits that drill pilot holes and countersink in one operation, giving clean, flush screw heads in timber, MDF or soft plastics. With sharp flutes for fast waste clearance and a hex shank for quick changes, it's the reliable set for cabinet makers, chippies and DIYers who want professional results without the fuss.
Why You’ll Love It
- Three common sizes (12mm, 16mm, 19mm) cover most screw and bolt countersinking jobs.
- One-step drilling and countersinking saves time and gives perfect flush finishes every time.
- Hex shank locks firm in impact drivers or quick-change chucks—no slipping under load.
Built for Real Work
Made from hardened HSS with five-flute design for smooth cutting and reduced heat buildup. The adjustable depth stop on each bit lets you dial in the exact countersink depth—tough kit that handles softwoods, hardwoods and composites without burning or tearing out, proven on Aussie sites and workshops for clean, splinter-free results.
Perfect For
- Tradies countersinking deck screws, cabinet hinges or structural fixings on site.
- DIYers building furniture, installing shelves or finishing timber projects at home.
