【Diamond Cutting Disc】The 4.5-inch cutting disc is manufactured using diamond material and a solid steel core, delivering clean cuts without contamination, maintaining shape integrity, and producing fewer dust particles.
【Product Specifications】Diamond cutting disc diameter: 4.5 inches (115 mm); arbor bore diameter: 7/8 inch (22 mm); compatible with all 7/8-inch angle grinders. Maximum rotational speed reaches 13,800 revolutions per minute.
【Precision Cutting】The 4.5-inch metal cutting disc delivers exceptional sharpness, safety, and high-speed performance while maintaining original wheel diameter.
【Damage-Resistant Design】The solid steel wheel body significantly reduces fracture risk, offering superior controllability compared to standard discs while minimising sparks and dust generation.
【Versatile Application】 This 4.5-inch diamond cutting disc is suitable for diverse materials and surfaces, including angle iron, channel steel, cast iron, square tubing, round tubing, PVC, stainless steel, tyres, and rubber products. Note: Not suitable for hardened steel.
【Smooth, Controllable Cutting】Compared to aggressive fibre discs, its cutting speed is easier to control, reducing binding and providing greater precision for fine work or grinding (not limited to cutting).
All products can cut concrete, stone, metal and composite materials. They use diamond coating technology, which increases the service life by more than 50% compared with ordinary tools and have excellent heat resistance.
