Internal Combustion Rail Drilling Machine

The NZG-31 is a highly effective, portable rail drilling machine essential for both routine maintenance and urgent track repair operations. This unit is powered by a reliable internal combustion engine, ensuring full operational autonomy in non-electrified or remote track sections. Designed for speed and accuracy, the NZG-31 facilitates the creation of precision bolt holes in the rail web for joint installation, bonding, or signalling equipment attachment. Its robust construction and stable clamping system ensure that hole quality consistently meets stringent railway industry standards. The machine supports advanced drilling technologies, including high cobalt steel and hard alloy hollow drill bits, which provide high wear resistance and superior chip removal performance. The quick-setup and easy-to-use design makes the NZG-31 an indispensable asset for track crews requiring mobility and high throughput in the field.
