Horn Milling Tools Feature Double-Edged Carbide Insert

Horn is expanding its tool portfolio for gear cutting to include types for milling power take-off (PTO) shafts. The standardized tool range is designed to provide high milling performance. Featuring a S274 double-edged carbide insert, the range includes tools for PTO shaft sizes 1 3/8" and 1 3/4". The portfolio also includes milling cutters for restricted shaft clearances. The M274 toolholders are equipped with an internal coolant supply for targeted cooling. The carriers have a diameter of 63 mm (2.48") and 10 teeth.

Tractor attachments such as a mower or loader wagon do not have their own drive, and the mechanical drive energy of the tractor must be transferred to the attachment to operate them. PTO shafts, which can be switched on and off, are available as a secondary output of the tractor transmission. The energy can be utilized directly via a PTO shaft. A profiled shaft stub is connected to the PTO shaft of the attachment by splined or involute gears. The user attaches the PTO shaft to the stub shaft in an axial direction for operation. Rotationally symmetrical locks are used to secure the connection, which can be released without tools.
