Coolant-Thru Knock Outs

M8 Threaded Coolant-Thru Knock Out Tools for swiss machining. Inherently better by design, a brass tip has been engineered to direct coolant flow to more effectively flush debris from the sub spindle and protect the surface finish on sensitive parts. Advantages include the elimination of down time due to chip accumulation and damage to the sub spindle collet. Manufactured from 12L14 steel and available in 5 standard sizes!
