Circular Saw Blade GRAPHITE 190×30 mm, 40 teeth, tungsten carbide (MPN 57H670)

The GRAPHITE circular saw blade 190×30 mm with 40 tungsten carbide teeth is designed for precision cutting of wood and wood-based materials. With a 190 mm diameter and 30 mm bore, the blade fits circular saws that accept this dimension and is suitable for both handheld and table-mounted machines. The carbide-tipped teeth deliver enhanced wear resistance and maintain sharpness for prolonged periods, enabling consistent crosscuts and rip cuts with reduced need for frequent resharpening.

Advantages

The tungsten carbide tooth tips ensure improved durability and cutting performance compared to high-speed steel blades, offering a longer operational life and stable edge retention. The 40-tooth configuration balances cutting speed and finish quality, producing relatively smooth cut surfaces suitable for visible edges. The standard 30 mm bore and 190 mm diameter provide compatibility with a wide range of circular saw models, while the blade’s geometry is optimized for efficient chip removal and reduced vibration during operation.

Suitable for

• Precision crosscutting of softwood and hardwood panels
• Rip cuts in solid wood and laminated boards
• Cutting plywood, MDF and particleboard with cleaner edges
• Use in compatible handheld circular saws and table saws

Key specifications

• Blade diameter: 190 mm
• Bore (arbor) diameter: 30 mm
• Number of teeth: 40
• Tooth material: tungsten carbide tips
• Primary use: cutting wood and wood-based materials

How to use

Install the blade on a circular saw that accepts a 190 mm diameter and 30 mm bore, observing the saw manufacturer’s instructions for arbor mounting and flange orientation. Secure the blade with the appropriate flange and nut, ensuring correct torque and that the blade rotates in the indicated direction. Adjust cutting depth and fence or guide settings according to the workpiece thickness and desired cut type. Operate the saw at recommended speeds for wood cutting, feed the workpiece steadily, and avoid forcing the blade to prevent burning or chipping of the cutting edge.

Usage recommendations

For prolonged blade life and optimal cut quality, keep the blade clean from pitch and resin buildup, inspect teeth for wear or damage before use, and use appropriate feed rates and blade guards. When cutting engineered boards, consider using a sacrificial backing board to minimize tear-out. Replace the blade when carbide tips become chipped or significantly worn to maintain safe and accurate cutting performance.
