Royal Master 911NSW Hydraulic Pump Unit – Hydraulic Puncher
Made in Japan
Manufacturer: Royal Master
Model: 911NSW
Features
Our customers choose all units, from small, lightweight models to powerful types, for their excellent operability.
We use standard models to punch long holes. We also standardize long hole bits and maintain a large inventory.
Combined with Royal’s powerful double-acting hydraulic pump, these punching machines punch holes quickly, accurately, safely and quietly. **
The new 506NSW, a chisel for small section steel, with a 5｡ taper for channel steel is standard in stock.
*Long holes are an option for 1150SW only.
The noise occurs when the steel material is very hard.
Technical note:
When making holes with these punches, the hole diameter should be larger than the material thickness (SS400).
