Material-Specific Matching: Product Features & Application Scenarios of WHITE HORSE Four Series Cutting Discs

Improper selection of grinding discs will not only raise consumption costs but also easily scorch workpieces and trigger safety hazards in steel structure, foundry, stone and stainless steel processing industries. Targeting four core processing materials, Zhejiang White Horse Abrasives Co., Ltd. (brand: WHITE HORSE) develops cutting discs with differentiated formulas. Equipped with exclusive abrasives, resin binders and fiberglass reinforced structures, the product lines are tailored to diverse working conditions to fully meet the demands of various industries.

Core Features: Made of high-toughness brown fused alumina, reinforced with double thick fiberglass mesh, and compounded with high-temperature resistant impact-proof resin. It delivers sharp cutting performance and resists jamming; maximum linear speed reaches 80m/s, with rated RPM matching 9-inch hand-held angle grinders for impact-heavy rough cutting on castings.Application Scenarios: Cutting cast iron, cast steel, ductile iron and cast aluminum workpieces; removing gates and risers in foundries and rough machining of heavy cast blanks. Castings feature uneven hardness and generate strong cutting impact, which may cause chipping or cracking on ordinary discs. The impact-resistant structure of WHITE HORSE foundry discs enables continuous mass cutting and reduces disc replacement frequency.

Core Features: Formulated with silicon carbide abrasives and low-temperature flexible resin binder to minimize heat generation and deliver smooth cutting surfaces. The optimized thin-blade design lowers cutting resistance and prevents edge chipping on brittle stone materials.Application Scenarios: Cutting granite, marble, concrete, precast cement blocks, ceramic tiles and curb stones for stone processing factories and infrastructure wall grooving. Ordinary metal discs tend to crack and darken stone during cutting, while the exclusive stone formula avoids damage to brittle stone and delivers clean cuts without secondary polishing.

Core Features: Adopts standard brown fused alumina to balance sharpness and wear resistance with cost-effective performance. Double-layer mesh reinforcement ensures safety under high-speed operation.Application Scenarios: Cutting carbon steel, iron pipes, rebar, angle steel, channel steel and regular steel plates for steel structure workshops, ironwork fabrication and on-site pipe cutting, ideal for mass conventional metal processing.

Core Features: Zirconia alumina (ZA) abrasive formula with low heat generation and iron-free composition to avoid surface contamination. Dense double fiberglass mesh greatly improves heat dissipation, while the special binder prevents oxidation discoloration of chromium elements.Application Scenarios: Cutting and grinding stainless steel sheets, pipes, doors & windows, pressure vessels, kitchen hardware and thin-walled alloy workpieces. Stainless steel has poor thermal conductivity and is prone to blue-grey scorched oxidation layers. WHITE HORSE stainless steel series eliminates workpiece contamination at the raw material level, removing the need for pickling and secondary polishing and cutting processing costs drastically.

Technical engineers in the industry remind operators that cross-use of the four disc series is forbidden. Stone discs must never cut steel, and stainless steel workpieces shall not be processed with general metal discs. Long-term improper matching will lower finished product yield and shorten the service life of grinding discs.
