The Nibsburner factory will no longer be producing new stock. The items below are in stock at this time but are subject to prior sale. The only handpiece on the market at this time that will accept Nibsburner tips without modification is Burnmaster. The Nibsburner tips will fit as is but the best connection is achieved with the use of Burnmaster contact rods. Nibsburner tips will fit Colwood handpieces with modification by soldering. For any other questions regarding Nibsburner compatibility please contact customer service.
