ABSTRACT:
An auxiliary device for re-grinding spiral drills which includes a clamping channel for accommodating the spiral drill. The auxiliary device includes a polyhedronal shaped body which is adapted to be clamped onto the spiral drill. An outlet portion of the body is provided with at least one sight-edge running in parallel to a main cutting edge, with the sight-edge being several times longer than the main cutting edge. A bottom side of the body is formed as a supporting surface for supporting the same on a grinding table, with the supporting surface being inclined at a front clearance angle with respect to a longitudinal center axis of the drill. The body may be provided with two sight-edges at the outlet portion, with the sight-edges being inclined with respect to each other at an angle corresponding to a center angle of the drill. Additionally, the bottom as well as top side of the body may be fashioned as supporting surfaces set at the clearance angle with respect to the drill axis.
