This 16 inch  professional diamond concrete saw blade is equipped with 40mm ultra-high wear-resistant diamond segments for longer service life on pavement cutting. Standard 25.4mm central bore plus positioning hole fits most road cutting machines perfectly. The segments are sintered with pavement-specific wear-resistant alloy powder, optimized for asphalt, hardened concrete and cement roadways. It delivers sharp cutting and anti-tooth-falling performance, ideal for road grooving, expansion joint cutting and old pavement repair, compatible with both wet and dry construction work.

Joint cutting for factory floors and parking lots
Pavement grooving before municipal pipeline excavation
Road expansion construction and concrete curb stone separation

Notes for Use:
Verify machine rated speed matches 400mm(16") blade before installation; overspeed operation forbidden.
Match flange to 25.4mm bore, align positioning hole and lock tightly; start machine only when blade is stable.
Take cooling breaks during dry cutting to avoid high-temperature abrasion and diamond shedding.
Feed pavement at constant speed, never force the blade to prevent segment breakage and core deformation.
Store flat in dry space, avoid squeezing or hitting segment edges.
Shut down machine immediately if heavy vibration or offset cutting appears, inspect blade flatness and machine clamp.

Core Advantages:
40mm ultra-high diamond segments double single construction service life, reduce frequent blade replacement cost.
Pavement exclusive wear-resistant alloy formula keeps sharp when cutting asphalt & concrete, hard to dull.
Dual fixation of standard 25.4 bore + positioning hole prevents slipping and maintains stable concentricity at high speed.
15mm thick segments feature strong impact resistance, anti-breakage when cutting thick pavement.
Vacuum high-temperature sintering tightly bonds segments and core to avoid mass tooth falling during construction.
Dual wet & dry cutting formula works steadily for construction sites with or without water supply for dust reduction.
