The Diablo 5 in. x 6 Tooth Carbide Fiber Cement HardiBlade is a specialty circular saw blade engineered specifically for cutting fiber cement siding and decking materials. Built by Diablo and featuring abrasion-resistant Freud TiCo carbide teeth with a Perma-shield non-stick coating, this trim saw blade delivers fast, clean, low-dust cuts through one of the most demanding building materials in residential construction. The super thin laser-cut kerf and precision-ground 6 TCG tooth configuration make it a reliable choice for contractors and installers working with fiber cement products on siding and decking applications.

Key Features

• Abrasion-resistant Freud TiCo carbide with Perma-shield non-stick coating - resists the highly abrasive nature of fiber cement while protecting the blade from heat, rust, and corrosion for extended blade life
• Super thin.071 in. laser-cut kerf - removes less material per pass for faster cuts with significantly less dust, reducing cleanup time and improving cut efficiency
• 6 TCG (Triple Chip Grind) tooth configuration at a 10 deg. hook angle - optimized geometry for accurate, clean cuts through hard, brittle fiber cement without chipping or cracking
• Laser-cut stabilizer vents - trap noise and vibration during cutting for improved accuracy and a smoother overall cutting experience
• 5/8 in. arbor compatibility - fits all standard 5/8 in. arbor trim saws, making it easy to swap in without additional adapters
• 12,000 maximum RPM rating - supports full-speed operation on compatible trim saws for productive cutting without blade stress

Why This Product

• Fiber cement is highly abrasive and wears out standard blades quickly - the Freud TiCo carbide formula is specifically engineered to resist that abrasion, extending the working life of the blade through demanding siding and decking jobs
• The Perma-shield non-stick coating provides three-way protection against heat buildup, rust, and corrosion - keeping the blade performing consistently even in outdoor jobsite conditions
• The super thin laser-cut kerf minimizes dust generation, which is a key concern when cutting fiber cement - reducing airborne particles and keeping the work area cleaner without sacrificing cut speed
• Designed for trim saws with a 5/8 in. arbor, this 5 in. blade fits a wide range of compact circular saws commonly used for fiber cement siding and decking installation, eliminating compatibility guesswork on the jobsite

Frequently Asked Questions

What type of saw is this blade designed for?

This blade is designed for use with a trim saw. It features a 5 in. diameter and a 5/8 in. arbor, and is rated for a maximum of 12,000 RPM, making it compatible with standard 5/8 in. arbor trim saws used in fiber cement siding and decking work.

Why is a specialized blade needed for cutting fiber cement?

Fiber cement is a highly abrasive material that rapidly wears down standard saw blades. This blade uses abrasion-resistant Freud TiCo carbide with a Perma-shield non-stick coating to withstand that abrasiveness, protecting the blade from heat, rust, and corrosion and delivering a longer working life compared to general-purpose blades.

How does this blade reduce dust when cutting fiber cement?

The blade features a super thin laser-cut kerf of.071 in., which removes less material per pass. This thinner cut produces significantly less dust than wider-kerf blades, helping to keep the work area cleaner during fiber cement siding and decking installation.

What does the laser-cut stabilizer vent design do?

The laser-cut stabilizer vents are precision-cut into the blade body to trap noise and vibration during cutting. This reduces blade movement and chatter, resulting in more accurate, cleaner cuts through fiber cement - an important factor when fitting siding panels or decking boards to tight tolerances.
