Pentruder’s New Core Drilling System
Published: 24/7
Tractive AB debuted its new Pentruder MDU3 core drilling system at the recent World of Concrete show.
A three-phase drill motor that does not require a powerpack, the MDU3 is available in three models that boast high power rates and a wide range of spindle speeds, making it suitable for all sorts of drilling tasks.
The 44.25-lbf (60Nm) MDU3-30 model accommodates drill bits of up to 11.8 in (300mm) in diameter, and has a range of 200 to 1,800 rpm. The 88.5-lbf (120Nm) MDU3-60 uses core drills of up to 23.6 in (600mm) has a range of 100 to 900 rpm. The powerful MDU3-100 operates with core bits of up to 39.4 in (1,000mm) in diameter at 50-450 rpm.
Pentruder’s sturdy drilling system is built around the brand’s TS-track, which is normally used together with the manufacturer’s wall saws, forming the basis for a number of drill rig options. The CEL-TS configuration—designed for line, stitch and corner drilling—consists of Pentruder’s track feet with the two TS-tracks mounted on it. With CEL-TS, the operator can move the track with the drill motor along the drill line for precise positioning of the core bit.
Designed for angle drilling, the PDT1 configuration allows the operator to drill at any angle, and maintain it as the pivoted head is moved along the track when stitch drilling. Depending on the job requirements, the rig can be fixed either on a baseplate or the two track feet. If used with the latter, the system can be installed in either a horizontal or vertical position.
The CER-M3-U configuration is intended for using the Pentruder drill rig with other brands of drill motors. The CER-M3-U universal drill carriage can also be combined with the CEL-TS stitch drilling rig or the PDT-1 pivoting head.
