Media could not be loaded. These little 30 degree cutters are great. I use them on hardwoods like Purple Heart and African Padauk and the engraving I do takes 3 to 4 hours, they stay sharp and make a very clean cut. They'll love what they do and they'll save you crazy money. Ignore bad reviews. I have been working with wood for over 35 years and have tried them all. I am very happy with the performance of these bits.
