Application flexibility: Dürselen standard drill heads

Dürselen standard drill heads are only 31.7 mm / 1 1/4" wide and thus can be used flexibly for different applications. Most file hole patterns can be drilled with these heads. Additionally they are used for multi-hole patterns for mechanical binding.

Standard drill heads can take up drill bits between 3 and 14 mm. Short drill bits with less than 80 mm total length are extended by using adapters. Paper drill bits with 16 mm shaft diameter are inserted directly into the drilling spindle. A reducer is used for taking up drill bits with 11 mm shaft diameter.

All Dürselen standard drill heads are prepared for drill bit cooling and lubrication. There are no interfering tubes running down the outside of the drill heads. Each head is simply connected to the air distribution unit using a plug-in coupling.
