Circular saw blade MEGA 450 mm, 7 TPI (model 64091)

Circular saw blade MEGA 450 mm, 7 TPI (model 64091) is a 450 mm diameter blade intended for use with compatible circular saws and sliding table saws. The blade's 7 teeth per inch configuration provides relatively large gullets and fewer cutting edges, which is suitable for fast, coarse cuts in appropriate materials. Before fitting the blade, verify compatibility with your saw's arbor diameter and maximum RPM to ensure safe operation.

Advantages

The 450 mm diameter delivers extended cutting reach and depth for larger workpieces, while the 7 TPI tooth count reduces clogging and improves chip clearance during heavy cuts. The blade design balances cutting speed and material removal, making it effective for tasks where aggressive cutting is preferred. Constructed for use on compatible machines, it supports steady performance under correct setup and maintenance.

Suitable for

• Coarse ripping of dimensional lumber and beams
• Crosscutting larger boards where a rough finished edge is acceptable
• Applications requiring rapid material removal and efficient chip evacuation
• Use on circular saws and sliding table saws that accept 450 mm blades

Key specifications

• Blade diameter: 450 mm
• Tooth count: 7 teeth per inch (TPI)
• Intended use: general-purpose coarse cutting and ripping
• Compatible machines: circular saws and sliding table saws designed for 450 mm blades

How to use

Install the blade following the saw manufacturer's instructions, ensuring the blade flange and arbor match and that the blade is secured tightly. Confirm the saw's maximum RPM rating is equal to or higher than the blade's operating speed. Use appropriate blade guards, push sticks, and work supports when cutting. Select feed rate and cutting depth appropriate to the material: slower feed rates for denser materials and faster feeds for softwoods to maintain efficient cutting and chip removal. Inspect the blade for damage or excessive wear before each use.

Usage recommendations

For best results, use this 7 TPI blade on tasks that prioritize fast material removal rather than fine finish. Wear appropriate personal protective equipment, maintain proper machine guards, and avoid cutting materials containing nails, screws, or other embedded metal to prevent damage to the teeth.
