Circular saw blade GRAPHITE 250x30x3.2 mm 40T (model 57H684)

Circular saw blade GRAPHITE 250x30x3.2 mm with 40 teeth is a general-purpose cutting blade intended for standard circular saws with a 30 mm bore. The 250 mm diameter and 3.2 mm plate thickness provide a balance between rigidity and cutting speed, while the 40 carbide-tipped teeth are designed to deliver smoother crosscuts and rip cuts in solid wood and wood-based panels. The blade is suitable for carpentry, cabinetry and DIY workshop tasks where a cleaner finish and reduced tear-out are required.

Advantages

The carbide-tipped teeth maintain cutting performance and edge life longer than plain steel teeth, enabling consistent results across multiple cuts. The 3.2 mm plate thickness gives increased stability and reduced blade deflection under load, which helps to improve cut accuracy. With a 30 mm center bore the blade fits a wide range of standard circular saws and table saws without additional adapters. The 40-tooth configuration balances cutting speed and finish quality, producing relatively smooth edges on both solid wood and engineered panels.

Suitable for

• Crosscutting and ripping of soft and hardwoods
• Cutting plywood, MDF and particleboard
• Carpentry and furniture making
• DIY renovation and workshop projects

Key specifications

• Diameter: 250 mm

• Suitable materials: solid wood, plywood, MDF, particleboard

How to use

Install the blade on a compatible circular saw or table saw with a 30 mm arbor, following the tool manufacturer's instructions for correct flange orientation and torque. Ensure the saw is disconnected from power during installation. Set the cutting depth and fences as required for the workpiece, and carry out a test cut on scrap material to confirm alignment and finish. Use steady feed speed appropriate to the material to avoid burning or chipping; allow the blade to do the cutting rather than forcing the feed.

Usage recommendations

Use appropriate personal protective equipment (eye and hearing protection, dust mask) and secure the workpiece. For best finish on plywood and thin laminates, consider using a sacrificial backing board to reduce tear-out. Regularly inspect the blade for damage and replace it if teeth are chipped or the blade is warped.
