Add these adapters onto cordless grinders in order to bevel smooth edges on plastic pipe and tubing, which help you create leak-tight cement connections. They cut using carbide router bits (sold separately). To set the length of the beveled edge and ensure an even bevel all the way around, there’s an adjustable guide that you hold perpendicular to the pipe as you cut. All come with an outside beveler guard, which covers the router bit’s sharp edges and stops plastic shavings from flying out.

Inside Beveler Guards—Swap outside beveler guards for inside beveler guards if you want to bevel the inside edge of pipe and tubing instead.
