APT Pneumatics’ Heavy Duty Grinders are built for high-load applications that involve sustained grinding, weld leveling, scale removal, and material shaping on large or hardened components. These grinders operate with reinforced bodies and high-power rotary output, making them suitable for aggressive surface work in tough industrial environments. These Heavy Duty Grinders are equipped with quick action constant speed governor to maintain optimum cutting speed under varying loads.
Frequently deployed in foundries, shipbuilding, steel fabrication, and equipment manufacturing units, these tools are engineered to manage abrasive forces on dense materials such as cast iron, mild steel, and structural alloys.
With components designed to handle vibration, weight, and continuous air supply under load, APT’s Heavy Duty Grinders are made for repetitive industrial cycles. Their structural configuration supports extended wheel usage, high grinding torque, and consistent speed control—ensuring performance continuity across multi-shift operations.

Models are compatible with 100 mm, 150 mm, and 180 mm wheels, making them suitable for a wide range of grinding loads from medium to heavy abrasion.
Free speeds range from 6,000 to 9,000 RPM — optimized for heavy stock removal, weld grinding, and shaping applications without overcutting.
Tool lengths up to 556 mm provide additional reach and surface control, reducing vibration transfer and supporting uniform contact pressure during grinding.
With tool weights ranging from 2.45 kg to 6.5 kg, these grinders deliver steady force transfer for applications involving high surface resistance or scale removal.
APT Pneumatics’ Heavy Duty Grinders are purpose-built for demanding surface correction tasks where sustained torque and abrasive force are required. These tools are widely deployed in heavy engineering environments for structural work, post-weld finishing, and casting cleanup—especially on large and dense metal components.
