Kotec newRun10DX CNC beam drilling lineH-beams up to 1,000 x 500 mm

Used here for: Floor beams at every level

Heavy profiles that need precise holes, where plasma cannot do the job: the lower structure and panel borders of a ground flare, and every bolted PEB and multi-storey frame.

• H-beams up to 1,000 x 500 mm
• Drills 3 faces in one pass
• Channels, angles and box sections
