TOMAX PCDM10 10in 6 Tooth PCD Fiber Cement Saw Blade - Fast Cuts

In this review the TOMAX PCDM10 10in 6 tooth polycrystalline diamond tipped saw blade is judged on its ability to cut fiber cement siding and similar materials. The bottom line: this blade is for contractors and DIYers who need clean, durable cuts through HardiePlank, Cemplank and other fiber cement products, with the biggest reason to buy being its abrasion-resistant polycrystalline diamond tipped teeth that deliver faster cutting and extended life compared with standard carbide blades.

Key Features

• Designed for fiber cement: The blade is specifically made to cut HardiePlank, Cemplank and other fiber cement boards cleanly without excessive chipping.
• 6 PCD teeth: Six polycrystalline diamond-tipped teeth resist wear and help maintain cutting performance over repeated cuts.
• Abrasion-resistant tips: The PCD tips reduce wear and allow faster cutting through abrasive cement-based material.
• Extra-large gullet: Large gullets improve material removal and help minimize dust buildup at the cut line for smoother edges.
• 5/8in arbor fit: Standard 5/8in arbor diameter fits common circular saws for easy mounting and stable operation.

Who It's For

The TOMAX PCDM10 is best for siding installers, remodelers and serious DIYers who cut a steady volume of fiber cement sheets and need cleaner edges and longer blade life than typical carbide blades provide. Its PCD tips and gullet design make it especially useful when working on full sheets where smooth, chip-free ends matter.

It is less appropriate for those who only occasionally trim wood, plywood or nonabrasive materials where a cheaper general-purpose blade would be more economical. Users who require extremely fine finish cuts for trim work on delicate materials should consider a blade specifically made for finish woodworking rather than an abrasive-material PCD blade.

Pros & Cons

Pros

• Cuts fiber cement like HardiePlank and Cemplank cleanly with smooth edges.
• PCD tips offer increased durability and faster cutting through abrasive material.
• Extra-large gullets improve debris removal and reduce dust buildup during cuts.
• Standard 5/8in arbor fits many circular saws for straightforward use.

Cons

• Durability reports are mixed; while many users find it long-lasting, a few have reported breakage on first use, so careful handling and correct mounting are essential.
• With only six teeth, it is optimized for abrasive boards rather than fine finish work on softer materials.

Frequently Asked Questions

Will this blade fit my circular saw?
It uses a standard 5/8in arbor and will fit most circular saws with that arbor size when mounted correctly.

Can this blade be used on plywood or trim?
It is designed for abrasive fiber cement; while it will cut other materials, the six PCD teeth are optimized for cement-based boards rather than fine finish work on wood.

How does it compare to carbide blades?
The abrasion-resistant PCD tips are intended to cut faster and last longer on fiber cement than typical carbide-tipped blades, delivering cleaner edges on those materials.
