Piercing saw blades x 30
This box contains 3 grades of piercing saw blades - coarse, medium, fine. Fits all popular piercing saw frames. Piercing saws (not included) are the preferred professional choice when it comes to armature fabrication. Unlike junior hacksaws, Piercing saws have a very thin blade perfect for following a pattern outline in thin sheet steel (perfect for cutting out steel feet for example).
