⚡ At a Glance
- • Cutting Quality: Three-point triangular tip with chip evacuation grooves for cleaner, faster cuts
- • Best for: DIYers and tradespeople needing quick, repeatable holes in wood and plastics
- • Not ideal for: Precision mortises or very fine cabinetry where hole edge finish is critical
Three-point tip design and evacuation grooves speed penetration and keep cuts clean. Heat-treated carbon structural steel and a 1/4 inch hex shank deliver durability and quick changes.
Faster, cleaner holes, thanks to 3-point design
Triangular 3-point tips concentrate force at the centre while angled cutting edges slice material, and grooves channel chips clear of the hole. The approach minimises splintering and reduces the need for backer boards on many materials.
Rapid penetration results in neater edges and faster progress on repetitive drilling tasks, making on-site work less fiddly and more efficient.
Quick bit changes, with 1/4 inch hex shank
A 1/4 inch quick-change hex shank fits standard quick-change chucks and drivers, while grooves on the shank improve grip and reduce rotational slip. The hex format removes the need to tighten a keyed chuck for many cordless drivers.
Swap sizes rapidly between holes, cutting downtime and keeping workflow steady when using cordless or bench drills with compatible chucks.
Longer working life, with heat-treated carbon steel
Carbon structural steel undergoes heat treatment to reach hardness levels around HRC48, improving strength, wear resistance and resilience under load. The construction resists dulling during typical woodworking use.
Durable edges mean fewer replacements and more consistent performance over time, suited to regular DIY and light trade use.
