Excellent value for money. I've used 1", 3/4" and 1/2" cutters and they all worked well and cut clean threads. Lubricate the ratchet with chain lube or similar. Cut at medium speed with plenty of lube and reverse, to break thread chips every few turns or if you feel a sudden increase in cutting resistance Lubricate the cutting surfaces with oil during storage to keep the tools sharp and prevent rust.
