This milling accessory has surpassed my expectations .My analysis of this product showed that it is an excellent addition to any industrial and scientific setting. The set-up process was quick and easy, and the accessory made accurate cuts WITH precision and consistency. The carbide-tipped cutters were robust and durable enough to last through demanding jobs. Although the price was reasonable, this type of accessory may not be needed for those who don't require industrial-quality equipment..
