Deburring reamer

When deburring with conventional reamers the burr between tool and hole wall is only folded over. The machining process suffers. In contrast to conventional reamers with the new deburring reamer EWR 500 the burr is process reliably cut. The radially exiting coolant pressure closes the gap on the opposite side between the reamer and the hole wall. The contact pressure enables a clean removal of the burr at the root. The de-burring reamer can also be applied for fits, as the hole wall is not damaged. Position and number of exit holes are adapted depending on the application task. Thanks to several coolant exit holes a permanent contact pressure is ensured. This prevents a pressure drop in the cross hole area. The surface finish quality of the reamed hole is retained. Short process times as rapid movement is possible outside the cross hole. Flexible diameter range of the deburring tool.
