Product Details

Product Description
The diamond segments are joined to the steel core using a mature high-frequency welding process. This production method provides reliable segment attachment and an effective balance between cutting performance, product consistency, and purchasing cost. The series is an economical solution for professional contractors, rental companies, distributors, and wall saw users handling routine concrete cutting work.
The broad U-shaped diamond segments provide a substantial working surface and stable load distribution. Gaps between the segments, together with the rounded expansion slots in the steel core, create passages for cooling water, concrete slurry, and cutting debris. These features help control heat and support smooth blade operation during wet cutting.
Three standard diameters, multiple bore options, and auxiliary positioning-hole configurations allow the series to fit different wall saws and cutting-depth requirements. Diamond segment bonds can be selected according to aggregate hardness, reinforcement density, wall saw power, and the required balance between cutting speed and blade life.
Product Specifications
Advantages
Economical and Practical
The established high-frequency welding process provides a dependable balance of production efficiency, consistent performance, and competitive cost. It is suitable for routine concrete cutting, regular consumable purchasing, and bulk stock orders.
Sharp, Smooth Cutting
Segmented diamond cutting elements continually expose effective cutting edges. When the correct bond is selected and sufficient cooling water is supplied, the blade cuts smoothly with controlled resistance and stable feed.
Consistent Quality
Evenly distributed segments, a stable steel core, and controlled welded joints help maintain balanced rotation and predictable cutting performance during repeated professional use.
Broad U-Shaped Segments
The catalogue specifies 40×12×5.2 mm U-shaped segments. Their broad working profile provides good load capacity, stable contact, and space for cooling and debris removal.
Common Wall Saw Sizes
Blade diameters of 834, 1,009, and 1,209 mm cover commonly required medium and large wall saw cutting depths. Bore options of 35, 50, and 60 mm facilitate compatibility with different spindle and flange systems.
Material-Specific Segment Options
Segment formulations can be matched to normal concrete, different aggregate hardness levels, and varying reinforcement densities. Customers can select a sharper or more wear-resistant bond according to project priorities.

Blade Selection Guide
Before ordering, confirm the wall saw brand and model, spindle bore, auxiliary positioning holes, flange arrangement, maximum permitted blade diameter, motor power, and blade guard capacity. The selected blade diameter must remain within the limits of the wall saw and its blade guard, while the bore and positioning-hole pattern must match the mounting flange precisely.
The diamond segment bond should also be selected according to the material being cut. Hard aggregates generally require a bond that maintains cutting sharpness, while abrasive or softer materials may require a more wear-resistant formulation. Reinforcement density, machine power, cooling-water supply, and the preferred balance between speed and service life should all be considered.
For normal concrete and conventional reinforcement levels, where overall purchasing economy is important, the high-frequency welded series is a practical choice. For continuous high-power operation, very high peripheral speed, heavily reinforced concrete, or applications requiring greater segment-joint strength, a laser-welded blade should also be evaluated.
