Product Description

Product Overview of 300mm Segmented Diamond Saw Blade

The 300mm segmented diamond saw blade is engineered for marble fabrication workshops that require clean slab cuts with reduced edge chipping. Manufactured by Quanzhou Zhongzhi New Material Technology Co., Ltd., this blade features sintered diamond segments bonded to a precision-ground steel core. Each unit is marked with a Φ300mm diameter and Φ60mm arbor hole, and is designated as a wet-cut blade for marble processing. The segmented rim incorporates J-shaped cooling slots between segments, allowing water to reach the cutting zone and dissipate heat during continuous operation. Business buyers can request custom segment dimensions and bond hardness formulations matched to their production line.

Design Features of 300mm Segmented Diamond Saw Blade

Segmented Rim with J-Slot Cooling

The rim consists of individually sintered diamond segments separated by J-shaped expansion slots. This geometry allows the steel core to flex under thermal load without warping, while the slots channel coolant to the cutting interface. The segment design also provides clearance for swarf removal, reducing friction and maintaining cutting consistency across the blade service life.

Sintered Diamond Bond Formulated for Marble

Each segment is produced through a high-temperature sintering process that bonds diamond grit within a metal matrix. The bond hardness is formulated for marble — a medium-hardness calcareous stone — to balance cutting speed with segment wear rate. The diamond grit remains exposed as the matrix wears, sustaining cutting performance without frequent dressing.

Precision Steel Core with Dynamic Balance

The steel core is laser-cut and dynamically balanced to minimize vibration at operating RPM. A reduced vibration profile contributes to cleaner cut edges and lower chipping on marble slabs. The core surface is treated for corrosion resistance, extending storage and service life in wet workshop environments.

Applications of 300mm Marble Cutting Disc

This blade is designed for bridge saws and table saws used in marble fabrication facilities. Primary applications include slab sizing from marble blocks, straight-line cutting of marble tiles and countertop blanks, and production cutting in plants with continuous feed systems. The Φ60mm arbor hole fits standard bridge saw spindles. This blade is formulated for marble and is not intended for granite or harder natural stones, which may accelerate segment wear. Commercial users should verify spindle compatibility before installation.

Manufacturing Quality of 300mm Diamond Saw Blade

Quanzhou Zhongzhi New Material Technology Co., Ltd. operates a manufacturing facility with diamond tool production capabilities. Each blade undergoes dimensional inspection, including diameter, arbor hole concentricity, and segment height verification, before packaging. The company supports OEM and ODM orders, allowing enterprise customers to specify segment dimensions, bond formulas, and branding markings. Production capacity and lead times are available upon request.
