Single & Triple Piston Scalers

Piston Scalers are used for many different surface preparation projects. They can be used to remove heavy rust, scale, paint or industrail coatings from metal surfaces. They can also be used to rough concrete prior to resurfacing. The pistons used for these applications range from standard steel (TX-00146) to carbide tipped (TX-00150) or REXALLOY ®™ which is a solid cobalt alloy (TX-00151). However, solid cobalt alloy pistons (TX-00151) should not be used for concrete surface preparations. It has been found that silica in concrete causes heat buildup in the REXALLOY ®™ pistons which in turn causes the pistons to wear more rapidly. REXALLOY®™ pistons should ONLY be used on metal surfaces and primarily for their spark resistance.
