⚡ At a Glance
- • Cutting Quality: Fast, clean cutting through metal, wood and plastics thanks to cobalt HSS teeth and positive rake design
- • Best for: Tradespeople and DIY enthusiasts working on metal fabrication, plumbing, electrical and general joinery
- • Not ideal for: Users who expect an included arbor and pilot drill, or who need to cut metal thicker than 3mm
Cuts up to 3mm stainless and mild steel and reaches 41mm hole saw depth. Extra cobalt HSS teeth and a 5.5 TPI positive rake tooth design speed up cutting while keeping edges clean.
Faster cuts - thanks to extra cobalt HSS tooth material and 5.5 TPI positive rake
Extra cobalt high-speed steel on the teeth increases hardness and heat resistance while a 5.5 TPI positive rake tooth geometry bites aggressively into material. The combination reduces cutting resistance and helps the blade advance smoothly.
Quicker penetration through a range of materials, meaning shorter drill times and steadier progress on repetitive jobs.
Cleaner holes with minimal burrs - with a non-binding clean edge design
A non-binding tooth profile and sharp tooth shape minimise clogging and reduce metal deformation at the cut edge. The design helps chips evacuate, producing a neater exit on many substrates.
Less follow-up filing or sanding required, so hole preparations finish faster and look more professional.
Versatile material compatibility - thanks to bimetal construction and specific cutting depth guidance
Bimetal construction pairs a durable backing with high-performance cutting teeth, allowing effective cutting of stainless and mild steel up to 3mm, plus wood, plastic and plaster. Recommended cutting depth guidance clarifies limits for softer materials.
One saw tackles common workshop jobs across materials, reducing the need to swap blades for typical interior and repair work.
