Paulimot HSS-Räumnadel 4 mm

This reaming tool can be used to create keyways with a width of 4 mm. Reaming tools are typically used in rack and pinion presses or hydraulic workshop presses. This reaming tool is made of HSS steel and is slightly tapered, with the cutting edges thickening in the direction of cut. As a result, with each tooth, the keyway becomes slightly deeper. To create a keyway, the workpiece is placed on the work table of the press, and the appropriate guide bushing is inserted into the hole of the workpiece. The reaming tool is then inserted into the holder, lubricated with sufficient cutting oil, and pressed through the workpiece using the press. To deepen the groove, spacers can be used.
