Been using these to drill steel at work and I'm impressed . Haven't had any break yet and they seem to stay sharp . Nice little case as well

Had them for over a year and soon to buy another set. For the price I didn’t have high expectations, but it turns out these cut and hold up incredibly well. Great stuff. Don’t forget to order a bottle of tap magic ;)
