2.9 HAAS A6AC A
The A6AC collet closer easily bolts to the back of the HRT A6 (see Figure 1a). The drawbar and collet adapters
are designed to mate with the Haas A6/5C spindle nose. The optional A6/3J and A6/16C may be obtained from
your local tooling distributor.
NOTE: A special drawtube adaptor is required for the 16C and 3J. Make sure to supply
tooling distributor with spindle/drawbar details as shown in figure 1-b.
