4.4 Regrinding spiral drill
Before regrinding a spiral drill first set the correct protruding length and the appropriate anglefor
the drill. The setting is performed in the opening "Adjusting device spiral drill".
After performing the setting the spiral drill is ground in opening "Regrinding of spiral drills".
For different materials or types of use, large drills can be adapted after re-sharpening in the
opening "Reducing the chisel edge".
For HSS twist drills, the grinding wheel made of cubic boron nitride already mounted in the
standard scope of delivery is used. For e.g. tungsten carbide drills, a diamond grinding wheel is
required, which is available under article no. 3100132 for the GH15T and under article no.
3100131 for the GH10T.
