About This Product
Laminam Cutting Blade for Thin Panels
The Alpha® Crossville Laminam 4-3/8" Diamond Blade is designed for high-speed cutting of Laminam® by Crossville®. Its smooth diamond rim and material-specific bond produce straight, true cuts with minimal chipping on thin, glass-like porcelain panels.
Continuous Rim Diamond Blade for Clean Cuts
The smooth continuous rim maintains consistent contact with the panel to support clean edges and controlled cutting. This cutting quality helps reduce damaged material when trimming close to panel edges.
Thin Porcelain Panel Cutting Blade for Detailed Cuts
The blade supports straight cuts, plunge cuts, trimming near panel edges, and internal-radius cuts. These capabilities make it suitable for fabrication and installation work where portable cutting and control are important.
Dry Laminam Cutting and Wet Panel Cutting
The blade can dry cut Crossville Laminam when used with compatible high-speed equipment. Alpha recommends wet cutting for other porcelain panels and glass tile, and water is required when the blade is used on a low-speed polisher. The LM0438 has a 4-3/8" diameter, 1.0 mm thickness, 7/8" and 20 mm arbor compatibility, and a 13,200 RPM maximum speed.
