An excellent automatic chucking solution at an affordable price

Our COBRA two-part clamping system is what most WALTER users think of as “the Schaublin nose cone” or the “Nann chuck,” and WALTER has gotten these from GDS for years. The COBRA offers excellent repeatability when changing blanks or collets, for optimal grinding results. And you can change collets quickly and in just a few simple steps. You can also adjust radial concentricity in just a few minutes.
