HSK GSK collet chuck in eight shanks — HSK32E, HSK40E, HSK50E, HSK40A, HSK50A, HSK63A, HSK100A and HSK63F — with six seats clamping 1 to 25mm. GSK is the seat system the international market lists as SK, so a GSK16 seat is quoted as SK16 — check seat and collet dimensions against the chart before interchanging. Each seat holds a continuous clamping range instead of one bore per diameter: GSK06 takes 1-6mm, GSK25 takes 5-25mm, and GSK10 and GSK16 carry the most models. Shanks are DIN 69893 hollow tapers, body diameter 19.5 to 55mm, projection 50 to 200mm — short for rigidity, long to reach into a pocket. Collets are sold separately; this is the tool holder. All 78 sizes are in the chart below.
