Drill square holes in wood with the HBM Profi 6 / 8 /10 / 12 mm Square Hole Drill Attachment for Pillar Drilling Machines. The set contains the various sizes of collars with which you can attach a bracket by means of a clamp attachment to the spindle shaft of almost any column drilling machine. If this bracket is attached to the shaft of the column drilling machine, the desired “square drill bit†can be clamped in this bracket. The “drilling of square holes†works as follows: The “square drill†consists of a normal wood drill bit that is clamped in the drill head of the drilling machine and a square “chisel†(broach) that fits closely around this wood drill bit. fits through and which is pushed down (through the wood) by moving the shaft of the drill press down. The rotating wood drill and the stationary square chisel are thus pressed through the wood at the same time as the shank. This creates a round hole (through a normal drilling operation) with (immediately afterwards) a square contour (due to the broaching operation with the square chisel).
