About This Product
FastCut Segmented Diamond Blades for Masonry
GATOR® FastCut™ Segmented Diamond Blades provide fast, general-purpose cutting through concrete, brick, block, stone, and stucco. Available in 4", 4-1/2", 7", and 14" diameters, the product line offers options for common grinder and masonry saw applications.
Fast and Efficient Masonry Cutting
Each segmented diamond blade features a durable diamond cutting edge designed to maintain cutting speed through hard, abrasive materials. Open spaces between the segments help clear dust and slurry while reducing heat buildup during demanding masonry cuts.
Wet or Dry Saw Blade Performance
FastCut saw blades support both wet and dry cutting for greater flexibility across different jobsites and equipment setups. Diameter-specific arbor configurations are available for compatible angle grinders, handheld saws, and walk-behind saws.
Common Questions
Frequently Asked Questions
What materials can GATOR FastCut Segmented Diamond Blades cut?
FastCut blades are designed for general-purpose masonry cutting in concrete, brick, concrete block, stone, and stucco. Their segmented rims prioritize cutting speed and debris removal in hard, abrasive materials. Select a blade diameter and arbor that match both the material and the saw being used.
Can GATOR FastCut blades be used for cutting tile?
FastCut blades are intended for concrete, brick, block, stone, and stucco rather than clean finish cuts in porcelain or ceramic tile. A continuous-rim tile saw blade is generally the better choice when minimizing edge chipping matters. Always match the blade specification to the exact tile material.
Can the FastCut diamond blades be used wet or dry?
Yes. GATOR FastCut Segmented Diamond Blades support wet or dry cutting. Wet cutting helps cool the blade and control airborne dust, while dry cutting provides flexibility where water is impractical. Follow the saw manufacturer’s instructions and use appropriate silica-dust controls and personal protective equipment.
Which GATOR FastCut blade sizes are available?
This listing includes four blade diameters: 4" (389873), 4-1/2" (389876), 7" (389879), and 14" (389882). Choose the size required by your saw. The blade diameter, guard capacity, arbor configuration, and maximum operating speed must all be compatible with the equipment.
What arbor sizes are available?
Arbor configurations vary by blade diameter. Available options across the FastCut line include 5/8", 7/8", 20 mm, and 1" arbors. Check the specifications for the selected blade and confirm that its arbor matches the saw spindle before ordering or installing the blade.
What is the maximum RPM for each FastCut blade?
The maximum speeds are 15,500 RPM for the 4" blade, 13,300 RPM for the 4-1/2" blade, 8,500 RPM for the 7" blade, and 5,500 RPM for the 14" blade. Never install a diamond blade on a saw that exceeds the blade’s marked maximum RPM.
