The CMT ITK Plus Diamond Saw Blade for Fiber Cement - 10" x 5/8", 6-Tooth TCG is engineered specifically for cutting ultra-hard fiber cement materials with diamond-tipped precision. With only 6 specialized teeth configured in a Triple Chip Grind (TCG) pattern, this blade delivers clean, chip-free cuts through fiber cement siding, panels, and boards - lasting up to 60 times longer than traditional carbide blades. Whether you are trimming HardiePlank lap siding, cutting Fermacell panels, or working with Eternit or Swisspearl products, this CMT diamond blade provides the durability and performance that demanding fiber cement applications require. Designed for use in portable circular saws and miter saws, it is an essential tool for contractors and installers who need reliable, long-lasting cuts through some of the toughest building materials available.

Key Features

• Diamond-Tipped Tooth Technology - diamond material provides cutting longevity up to 60 times longer than standard carbide blades, dramatically reducing blade changes and downtime on fiber cement projects.
• 6-Tooth Triple Chip Grind (TCG) Configuration - the TCG tooth geometry is specifically engineered for ultra-hard materials like fiber cement, delivering clean cuts without chipping, cracking, or splintering the material surface.
• 12 deg. Cutting Angle - the positive hook angle promotes smooth, controlled feed through dense fiber cement panels and boards, reducing operator fatigue on long cuts.
• 0.087" Kerf Thickness with 0.063" Plate - the thin kerf design minimizes material waste and reduces the load on the saw motor, making cuts more efficient in portable and stationary machines alike.
• 5/8" (15.88mm) Bore Diameter - fits the standard arbor size found on most portable circular saws and miter saws, allowing straightforward installation without adapters on a wide range of machines.
• Rated to 7,600 RPM - the high maximum speed rating ensures compatibility with a broad range of circular saws and miter saws used in fiber cement installation work.
• Broad Material Compatibility - cuts Eternit, Swisspearl, Fermacell, Ivarplank, HardiePlank, HardiePanel, chipboard, MDF, plasterboard, and thermoplastic materials, making it a versatile single-blade solution across multiple substrate types.

Why This Product

• Fiber cement is notoriously abrasive and wears out standard carbide blades quickly - this diamond blade lasts up to 60 times longer, meaning far fewer blade replacements and lower overall cost per cut on siding and panel installation jobs.
• The 6-tooth TCG configuration is purpose-built for ultra-hard materials rather than repurposed from a general-purpose blade design, so you get cuts specifically optimized for the hardness and brittleness of fiber cement without chipping or cracking.
• With compatibility across Eternit, Swisspearl, Fermacell, Ivarplank, HardiePlank, HardiePanel, plasterboard, chipboard, MDF, and thermoplastic materials, this single blade handles the full range of substrates commonly encountered on commercial and residential exterior cladding projects.
• Designed for portable circular saws and miter saws with a standard 5/8" bore, this blade integrates easily into existing tool setups without requiring special adapters or equipment.

Frequently Asked Questions

Why does this fiber cement blade only have 6 teeth?

Fiber cement is an ultra-hard, abrasive material. A low tooth count with a Triple Chip Grind (TCG) geometry is specifically designed for this application - fewer, larger diamond-tipped teeth clear debris efficiently and maintain cutting speed without overloading the blade or causing the brittle material to chip or crack. This configuration prioritizes durability and clean cuts over tooth count.

How much longer does this diamond blade last compared to a standard carbide blade on fiber cement?

According to CMT product data, this ITK Plus diamond blade delivers up to 60 times longer life than traditional carbide blades when cutting fiber cement and similar ultra-hard materials. This significantly reduces the frequency of blade changes on large-scale fiber cement siding or panel installation projects.

What machines is this blade compatible with?

This blade is designed for use in portable circular saws and miter saws. It features a 5/8" (15.88mm) bore diameter, which is the standard arbor size on most of these machines, and a maximum rating of 7,600 RPM to cover the speed range of typical portable and stationary cutting tools.

Can this blade cut materials other than fiber cement?

Yes. In addition to fiber cement brands such as Eternit, Swisspearl, Fermacell, Ivarplank, HardiePlank, and HardiePanel, this blade is also suitable for cutting chipboard, MDF, plasterboard, and thermoplastic materials - making it a versatile option for projects that involve multiple substrate types beyond fiber cement alone.
