Construct Wood AD 400 mm circular saw blade – 28 T, carbide-tipped, 3.5 mm kerf

The Construct Wood AD 400 mm circular saw blade is a heavy-duty construction blade engineered for cutting site timber containing nails and concrete splinters, offering durability and reliable cutting performance for professional workshops and trade use.

• 400 mm diameter, 28 teeth, carbide-tipped
• SK55 hardened steel backing
• 3.5 mm kerf, designed for construction wood

Durable construction for harsh site conditions

This circular saw blade combines a carbide-tipped tooth system with a hardened SK55 steel body to cope with the shocks and contaminants common on building sites. The specialised tooth geometry and broad support at the tooth gullet provide increased resistance to impacts from nails and concrete fragments, reducing the risk of premature chipping. The result is a blade that maintains its cutting geometry for longer, lowering downtime for blade changes and supporting uninterrupted workflow on the job.

Efficient cuts with consistent results

With a 400 mm diameter and 28 precision-ground teeth, the tool balances material removal and finish quality for structural timber work. The 3.5 mm kerf gives stable feed behaviour while limiting unnecessary material waste, and the carbide tips preserve sharpness under tough conditions. For practical terms: the hardened backing (>40 HRC) keeps the blade flat and true during high-speed operation, which translates into straight cuts and fewer reworks, benefiting both throughput and final part quality.

Safer handling and extended service life

The blade’s reinforced tooth support reduces the chance of tooth breakage when encountering foreign objects, enhancing operator safety and machine protection. The combination of hardmetal-tipped cutting edges and a robust steel core means fewer replacements and lower lifetime tooling costs. In addition, the design minimises vibration and helps maintain a consistent cut line, improving control and reducing strain on saw drives and feed systems.

FAQ

Is this blade suitable for cutting timber with embedded nails?
Yes. The Construct Wood AD 400 mm circular saw blade features carbide-tipped teeth and a reinforced tooth support that increase resistance to impacts from nails and similar foreign objects.

What makes the SK55 steel backing important?
The SK55 steel used in the blade’s body provides dimensional stability and a hardened backbone (>40 HRC), which helps the blade stay true under load and prolongs the life of the carbide tips.

Which machines is the 400 mm blade compatible with?
The blade is intended for stationary and portable saws that accept a 400 mm blade diameter and a 3.5 mm kerf; verify machine power and flange specifications before mounting the blade.

How does the special tooth geometry affect cutting performance?
The specially designed tooth profile and broader tooth support distribute cutting forces and resist chipping when encountering debris, delivering more consistent cuts and longer tip life.
