The Black 450 core bit is ideal for medium and large hole diameters. This core bit range was developed to offer a product of the same quality as the Silver 450 core bit but with a more attractive price, thus making it ideal for those who don’t use it every day. Completely similar to the Silver 450 core bit, the difference lies essentially in the segment welding, which in this case is laser welded.
