HHBA21 Drill holder Starrett SDS-plus with high-speed drill.
With this drill holder, the hole saw can be used with SDS-Plus hammer drills, NOTE. With the hammer function turned off.
The drill holder has two locating pins inserted into the hole saw cap to prevent the hole saw from over-tightening the screw thread.
This enables easy and immediate hole saw changes, without tools and without removing the spindle from the chuck.
