High Cutting Brazed Diamond Blade Ceramic Tile Cutting

Product Overview of Brazed Diamond Blade

The brazed diamond blade is manufactured by Quanzhou Zhongzhi New Material Technology Co., Ltd., established in 2003. Engineered for floor saws and stationary cutting machines, this blade features brazed diamond segments with wide gullets designed for stable cutting of concrete and reinforced concrete. The brazing process creates a strong metallurgical bond between the segment and the steel core, ensuring segment retention under the high-load conditions encountered in concrete cutting. The standard 300mm diameter blade carries 21 segments with dimensions of 40×3.0×12 mm, and the product range extends from D300 to D800 with segment counts from 21 to 57 to suit different machine sizes and cutting depths. Core thickness options include 20mm, 22.23mm, 25.4mm, 30.5mm, 50mm, and 60mm to fit common floor saw arbor standards. This blade is suitable for road construction, demolition, and concrete processing applications where straight, stable cuts are required.

Design and Construction of Brazed Diamond Blade

Brazed Segment Attachment

Each diamond segment is attached to the steel core using a brazing process that creates a metallurgical bond at the segment-core interface. This attachment method provides higher heat resistance and mechanical strength compared to adhesive bonding, reducing the risk of segment detachment during heavy-duty concrete cutting. The brazed joint maintains integrity at the elevated temperatures generated during continuous cutting operations, contributing to consistent performance across the blade's service life.

Wide Gullet and Core Design

The blade features wide gullets between segments to facilitate efficient removal of concrete slurry and cutting debris. This design helps prevent clogging during deep cuts in reinforced concrete, where steel rebar can generate additional heat and material buildup. The steel core is precision-machined with tensioning to maintain flatness during rotation, reducing blade wobble and producing straight cut lines. Core thickness options cover standard arbor sizes used in floor saws and table cutting machines across major global markets.

Applications of Brazed Diamond Blade

Road and Construction Concrete Cutting

In road construction and maintenance projects, the 300mm brazed blade is used for cutting expansion joints, control joints, and removal sections in concrete pavements. The wide gullet design efficiently clears concrete slurry, allowing the blade to maintain consistent cutting speed through full-depth passes. For reinforced concrete containing steel rebar, the brazed segment attachment provides the structural integrity needed to handle intermittent contact with metal without segment loss. This blade is suitable for use on walk-behind floor saws commonly deployed in highway, airport runway, and commercial parking structure projects.

Demolition and Concrete Processing

For demolition and concrete processing operations, the blade cuts concrete slabs, walls, and structural elements to facilitate controlled removal. The D300 to D800 size range allows contractors to match blade diameter to cutting depth requirements, from shallow slab cuts to deep structural sectioning. Brazed construction provides durability in demanding site conditions where the blade may encounter embedded aggregate, rebar, and variable concrete densities. Enterprise customers in the demolition and concrete recycling sectors can use the full diameter range to equip their machine fleets with a single blade product line.

Customization and Procurement for Brazed Diamond Blade

Zhongzhi provides OEM and ODM customization for industrial clients, including private-label core printing, modified segment formulas for specific concrete compressive strength ranges, and custom core thicknesses for non-standard machine arbors. The standard product range covers D300 through D800 with six core thickness options. Buyers can order mixed diameters within a single shipment to build a complete product catalog. Payment terms include T/T, L/C, D/A, and D/P, with shipping via sea freight for volume orders and air or express for sample and trial quantities. Business buyers are encouraged to provide their machine model, arbor size, target concrete type, and expected cutting depth to receive a precise blade specification recommendation.

FAQ

What materials is the 300mm brazed diamond blade designed to cut?

The blade is designed for cutting concrete and reinforced concrete. It is suitable for plain concrete, reinforced concrete containing steel rebar, and concrete with aggregate commonly found in road and structural applications. It is not formulated for ceramic tile or porcelain cutting, which requires a different bond and rim configuration.

What core thickness options are available?

Six core thickness options are available: 20mm, 22.23mm, 25.4mm, 30.5mm, 50mm, and 60mm. These cover the standard arbor sizes used on floor saws and stationary cutting machines in major global markets. Custom thicknesses can be produced through ODM service for non-standard machine models.

What diameter range does this product line cover?

The brazed diamond blade product line covers diameters from D300 to D800, with segment counts ranging from 21 segments on the D300 to 57 segments on the D800. Segment thickness increases progressively from 3.0mm to 5.5mm across the diameter range to match the cutting load of larger machines.

Can the blade be used for dry cutting?

The brazed diamond blade is designed primarily for wet cutting on floor saws, where water cools the blade and clears debris. Dry cutting may be possible for short, intermittent cuts but will reduce blade life and may generate excessive heat. Zhongzhi recommends wet cutting for optimal performance and segment retention in concrete applications.
