About Set Screw Holders
These are the least expensive and most popular holders. They are commonly used for general milling, facing. The 3/8" and 1/2" set screw holders are intended to be used with end mills that have a Weldon flat on them. They can also be used with certain Silver & Deming style drill bits. Make certain that the set screw is on the flat of the tool and never attempt to hold tooling without a flat.Any tool mounted in a set screw holder will be held about 0.0003" off center due to the set screw and the required clearance. This is not significant in 1/2" and 3/8" tooling, but begins to become important on smaller cutters. The ER20 collet holders will mount tooling on center, without the offset inherent to a set screw holder. The ER20 collet holders are recommended if you are using 1/4" or smaller cutters that are based on a larger shank diameter, even if the shank offers a Weldon flat for mounting. The set screw holders will work for this application, but the tool will last longer and the machined finish will be better when using an ER20 holder.
