Bootle-neck punch HSS
The Bottle-neck punch are used in cutting and punching tools which are primarily used to process materials which exert large punching and retracting forces on the punch. The specially designed toolhead shape optimizes the force vectors within the punch, reducing the likelihood of failure and therefore increases the life of the tool.
Our bottle-neck punch are made from HSS (high performance - high speed steel, material no. 1.3343 or similar) and have a shank hardness of 64 ± 2 HRc as well as a toolhead hardness of 52 ± 3 HRc.
In addition to the version with straight shank, we also produce shape B - with round recessed shank.
Other lengths and intermediate dimensions are promptly available upon request.
