Understanding drilling-tool terminology helps you order the right part the first time. This quick reference covers the core component families we stock at HP Drilling Equipment in Bochum, Germany.
Casing crowns & drill bits
The cutting head at the bottom of the string. Carbide buttons (round or ballistic) break the ground; the crown's diameter and thread connection must match your casing and drive system. We stock conical and cylindrical profiles in left- and right-hand threads.
Shank adapters
The interface between the rock drill (drifter) and the drill string — it transmits percussion and rotation. Specified by drifter model (e.g. HD, KD series) and thread (R, T, GT, C). The right shank adapter protects both your hammer and your rods.
Flushing shafts, heads & swivels
Flushing components inject air, water or mud to clear cuttings and cool the bit. A flushing swivel lets the string rotate while the supply line stays still. Box (female) and pin (male) ends are matched to the adjoining tools.
Ejection bells & drive adapters
Drive adapters and caps transmit torque and feed force down the string; ejection bells help recover casing. Profiles (conical/cylindrical), thread starts (e.g. 2- or 3-start) and hand (rh/lh) must align across the assembly.
