Mühlen TD-25
Professional Wire Binding Machine
Heavy-Duty, High-Volume Use
Designed specifically for schools, offices, and stationery shops for high-volume binding work, the MÜHLEN TD 25 wire binding machine is built for F4 (larger than A4, 210x330 mm) documents or smaller. The model can punch 25 sheets at a time and bind up to 200 sheets in a single set.
Punches 25 Sheets at a Time
With its separate punching lever system, the MÜHLEN TD25 can punch 25 F4-size (larger than A4, 210x330 mm) sheets at once. Thanks to its free pin system, it can also open round holes in any quantity from 1 to 40.
Binding Up to 200 Sheets
With a binding capacity of up to 200 sheets at once, the model lets users set the desired tightness between 1mm and 28mm thanks to its tightness adjustment system. This feature keeps the wire binding from being too loose or overlapping.
Margin Adjustment and Waste Box
The Mühlen TD-25 wire binding machine has 4 different margin adjustment levels. The 2.5 mm, 5 mm, 7 mm and 9 mm settings, which determine how close to or far from the edge documents are punched, offer great convenience to the user. It also collects the waste paper left over from punching in a removable tray.
Free Pin System
The model features a free pin system with 40 pins, allowing the user to punch as many holes as desired, from 1 to 40, at the spacing they choose. The biggest advantage of the free pin system is that it prevents half-holes from occurring at the corners.

Type of Material Used
The model can use flexible binding material and works with all wire binding materials in 3:1 and 2:1 pitch (3 or 2 holes per inch), and is compatible with binding ring sizes between 1 and 28 mm. It also offers much neater binding of documents thanks to its non-slip base and fixing clamp.
Dual Lever System and Strong Structure
The model performs punching and binding operations with separate lever systems, offering a much more practical and flexible structure. Its steel body and internal components are designed to provide years of service without loss of performance. In addition, the punching blades, made of special steel, carry a 5-year warranty.
