Product information
The Pentruder Modular Drill System MD1 is a versatile and powerful drilling system. The 4-speed MG41 gearbox gives the system a very smooth and efficient run and with two exchangeable spindle units it offers a wide speed range for different sizes of drill bits.
Quick disconnect couplings reduce the set up time. Small and big drill bits can be drilled in a shorter time than anyone thought possible.
Pentruder MD1 drill system can be driven by a 15, 18 or 22 kW HF-motor. Together with the MG41 gearbox and a ST2 or ST3 spindle unit and a Pentpak HF-power packs up to 1200 mm big holes can be drilled easily and efficiently.
Pentruder MD1 HF-drilling machine can either be built on the wall saw track (MCCS) or on the 70 mm column system.
Modular system
Combine different modules to suit your need. The basic equipment is a base plate, column, roller carriage, spindle unit, gearbox and HF-motor. The HF-drill system can be driven by the 15, 18 or 22 kW HF-motor.
Superstrong 4-speed gearbox
The MG41 4-speed gearbox is built to last. Together with a spindle unit it will offer a high torque and unbeatable unbeatable performance.
ERMD1 Extension adapter
When drilling big diameter holes over Ø 600 mm (23.6”)an extension adapter must be used to extend the distance between drill column and spindle, giving more clearance for bigger diameter drills. Each adapter extends the drill unit 90 mm (3.5”) further away from the column, i.e. gives additional clearance for a 180 mm (7”) bigger drill bit.
Very good stability
The carriage is very stable and gives perfect control over the drill bit.
High power and reliability
The Pentruder wall saws are powered by very powerful HF-motors. They all have very efficient cooling, high torque and are built by the best materials for reliability and a long lifetime. Reliable 400 Hz technology ensures a very reliable motor, long life of the bearings and no need for frequent maintenance.
Robust connectors
The connector housings are made in-house from high strength aluminium. At service the connector inserts can be replaced with hand tools.
