Unlike spindles, which operate within the controlled environment of a machine, tool holders can be exposed to many contaminants inside a shop. During storage and between uses, tool holders run a high risk of picking up oils, dust and other particles that can contaminate their surfaces—besides of course the coolant and chips from inside the machine. Taper and bore cleaners come in many styles and sizes to match all types of tooling.
The most common taper cleaners are for HSK and ISO tapered tool holders, as well as various collet chuck styles. On the other hand, bore cleaners are suitable for shrink fit, milling and hydraulic chucks. Keeping these contact surfaces clean is essential to maintain tool holder quality, accuracy and performance.
