BTA DRILLING · 500 SERIES
IHD drill headDiameter adjusted with cartridges.
The 500 series IHD is a BTA head whose diameter range is adjusted by changing cartridges. The size table covers Ø46.50–255.99 mm; range expansion cartridges (F+1–F+5) and pads (S+1–S+5) extend the diameter, and safety and sub guide pads protect the head.
