Construct Wood AD 400 mm Carbide-Tipped Circular Saw Blade – 28 Teeth (Bosch)

The Construct Wood AD 400 mm is a carbide-tipped circular saw blade designed for robust on-site timber cutting where embedded foreign objects are present

• Carbide-tipped teeth for extended life
• Special tooth geometry for impact resistance
• Hardened SK55 steel core (>40 HRC)
• Cuts site timber with nails and debris

Built for reliable on-site cutting and fewer production stops

The blade’s carbide-tipped teeth and a tooth geometry engineered for wide support at the tooth root deliver consistent cutting performance even when encountering nails or concrete residues in construction timber. This translates into fewer interrupted jobs and lower downtime on site because the wear-resistant tips maintain their edge longer than standard teeth. The result is a reliable blade that preserves saw motor efficiency and reduces the frequency of blade exchanges, contributing to measurable time savings in daily operations.

Robust steel core for dimensional stability and precision

A hardened SK55 steel core, treated to >40 HRC, provides a stable backbone that keeps the cutting line true under heavy loads. The increased material hardness reduces deformation; as a consequence, radial runout is minimised and the blade’s geometry is retained over more cycles. For workshops and site teams seeking consistent results, this means improved sawn-surface quality and less rework. The design combines impact resistance with sufficient rigidity to sustain high mechanical stress typical of construction applications.

Practical dimensions and handling to speed up workflow

With a diameter of 400 mm, 28 teeth and a 3.5 mm kerf, the blade balances cutting speed, chip evacuation and stability for coarse structural timber work. The moderate tooth count helps to deliver fast removal rates while the kerf supports robust, vibration-resistant cuts. The blade is suitable for standard 400 mm circular saws used on site and in workshop contexts; technical queries can be addressed by Metav Werkzeuge for machine compatibility and cutting parameter optimisation. Choosing a blade with these properties optimises throughput while maintaining acceptable surface quality for follow-up processes.

FAQ

What materials can this blade handle? The Construct Wood AD 400 mm circular saw blade (SKU 4000909154NW) by Robert Bosch Power Tools GmbH is specified for on-site structural timber and is designed to withstand embedded nails and concrete fragments during cutting.

How does the carbide tipping affect service life? Carbide-tipped teeth on the Construct Wood AD increase wear resistance compared with standard teeth, so the blade maintains cutting performance for longer intervals under abrasive, impact-prone site conditions.

What does the hardness rating (>40 HRC) mean for daily use? A hardness of >40 HRC, as found in the SK55 steel core of the Construct Wood AD, indicates enhanced resistance to deformation; this supports consistent cutting geometry and reduces the need for frequent blade replacement.

Is this blade suitable for my 400 mm site circular saw? Yes; the Construct Wood AD is a 400 mm diameter blade with a 3.5 mm kerf and 28 teeth, compatible with standard 400 mm circular saw machines—verify your machine’s arbor and guard specifications before installation.

Can the blade cut through nails without damage? The combination of special tooth geometry and carbide-tipped edges on the Construct Wood AD is engineered to resist impact from embedded nails and small concrete residues; this reduces the risk of sudden tooth failure compared with non-tipped blades.
