The RCBS trim Pro 3-way cutter is automated case preparation at its finest one of those accessories reloaders cant live without. Its unique three-blade head configuration trims cases like the standard cutting tool, but in addition to trimming to length, inside blades chamfer the case while an outside blade deburrs it. The 3-way cutter attaches easily to both case Trimmers and trim pros. Fits: .270 caliber.
