1-1/2" x 2-1/2" Cylindrical Plug - Straight (Type 18), Aluminum Oxide, 16 Grit, 5/8"-11 Thread, 24,192 Max RPM, Ultra Fine Grade, Suitable For Steel, Cast Steel and Cast Iron

PFERD cones and plugs are made of regular aluminum oxide in a high-quality resinoid bond. Because of their hardness, these products are noted for their good stock removal rates and high durability. Cones and plugs are used for steel, cast steel and cast iron.Advantages: High stock removal rate. High edge-holding and dimensional stability. Cool grinding properties reduce the thermal load on the workpiece.Application Examples: Weld dressing on steel removing excess weld metals. Chamfering in preparation of welding operations. Grinding in hard-to-reach workpiece areas. Removing parting lines and imperfections at casting parts. Smoothing rough castings.Recommendations for Use: Cones and plugs perform best at the recommended peripheral speed of 6,900 - 9,800 SFPM. Suitable drive systems include flexible shafts, electric or air-powered straight grinders and angle grinders.Safety recommendations: The maximum speed is calculated in accordance with ANSI B7.1. Never exceed the maximum RPM listed on the label.
