Ol' Blue Diamond Blade for Concrete and Masonry - 9"–20"
Ol' Blue is a dependable, fast-cutting diamond blade built for professional contractors cutting cured concrete, block, brick, and other hard materials. Its versatile design delivers a strong balance of cutting speed and blade life for everyday concrete and masonry work.
Key Benefits
• Fast, aggressive cutting in cured concrete, brick, block, and other hard materials.
• Soft-bond diamond matrix helps keep the blade cutting efficiently through hard materials.
• Balanced for dependable cutting speed and blade life across common concrete and masonry applications.
• Available in 9", 12", 14", 16", 18", and 20" diameters to fit a wide range of professional saws.
• Multiple arbor options make Ol' Blue a versatile choice for cut-off saws and masonry saws.
Built for Hard Materials
Ol' Blue is designed specifically for cured concrete, masonry, brick, block, and other hard materials. The blade uses a soft-bond diamond matrix that wears away at a controlled rate to continually expose fresh diamond while cutting. This helps the blade stay aggressive instead of glazing over when working in harder materials.
Fast Cutting with Dependable Blade Life
The diamond segment design provides a practical balance between cutting speed and blade life. For contractors moving between common concrete and masonry applications, Ol' Blue provides consistent performance without requiring a highly specialized blade for every cut.
Professional Diamond Segments
The 12" through 20" Ol' Blue blades feature .400" segment height and a .125" blade width for durable, consistent performance. The 9" version uses a thinner .080" blade width for smaller saw applications.
