Cutting tools 6 Cutting tools A multitude of cables and conductors of the most diverse types and versions are used to connect electrical and electronic components. The cables and conductors must be accurately prepared depending on the different types of connection. The quality of the cutting process is therefore highly significant. Weidmuller has become a specialist in the cutting of copper or aluminium cables. The product selection ranges from cutting tools for small cross sections with direct transmission of force to cutting tools for large diameters. Mechanical action in conjunction with the special cutting pattern reduces the manual forces required to a minimum. Weidmuller fulfils all the criteria for professional cable processing with its wide product range. The demand that we ourselves place on our products is: a smooth, straight cut, with no distortion of the conductor. You can benefit from this too. 7 Cutting tools KT 8 * KT 12 Cutting tools Blade geometry for different conductor sizes increases the precision when cutting smaller conductors KT 8 KT 12 Precisely cuts copper and aluminium cables up to 8 mm o Precisely cuts copper and aluminium cables up to 12 mm o maximum cutting capacity: maximum cutting capacity: Copper cable 16 mm2 solid 16 mm2 stranded 16 mm2 flexible Aluminium cable 16 mm2 stranded Copper cable 16 mm2 solid 25 mm2 stranded 35 mm2 flexible Aluminium cable 16 mm2 stranded Not suitable for cutting steel wire, steel-shielded cables, aluminium alloys and hard-drawn copper conductors!

The requirement for all cutting tools is: Smooth, straight cut without distortion of the conductor. Insulation Cutting motion According to DIN 8588, a distinction is made among scissor cuts, wedge-action cutting, tearing and breaking. Scissor cutting is employed particularly in the cutting of cables, wires and conductors. Cutting tools with cross blades should perform an oblique cut and operate free of play. Conductor Clean cut A "dirty" cut may have the following appearance: Push cut Sheared conductor Oblique cut Cutting is differentiated fundamentally according to the following cutting processes: Push cutting Oblique cutting Pulled out conductor With a push cut, the cutting movement occurs vertically between the tool and workpiece. With an oblique cut, the cutting motion occurs at an angle to the tool. Position of cuts Crushed cable The essential quality characteristics for professional cutting tools are a cutting edge shape which is suited to and optimised for the corresponding application, so that the manual forces required for cutting remain low. This allows single-handed operation. A further quality characteristic is the cutting angle, i.e., the sharpness of the blade and the existence of a facet. This is the deliberate slight increase in the cutting angle, as a result of which the duration of life of the cutting edge and cutting edge sharpness is increased. upper cutter Position 1 Position 2 In position 1, the cuts are made immediately in the full length, i.e., much force is required. In position 2, the cuts cross one another as occurs with scissors (scissor cut), i.e., the cut is made with lateral displacement, so that less force is required. blade faced lower cutter Tools supplied by Weidmuller comply with all requirements imposed on professional cutting tools. 14 Cutting tools Cutting tools 15
