Broacher for square holes
Execution: HSS, with guide pivot. The journal is inserted into the pre-hole of the workpiece, ensuring the alignment of the square inner profile. So that only one pass is needed for a small overall length, a slightly larger outlet opening (in tolerance H8) should be selected. The cutting surfaces are thoroughly ground on all sides and allow for a smooth surface.
Application: for precise production of internal square profiles at right angles. There is no need for special machines or set-up times. For the production of machine components, templates, welding jigs, drilling and fastenings. The rake angle is prepared for steel processing, but it is also suitable for cast iron, bronze and aluminium.
