Why Reed

One combination machine assembles as a drilling machine or a direct tapping machine. Offers 10%+ cost savings versus the purchase of two separate machines.

Combination Drilling/Tapping Machines are easier to use, save operating time, and are a better value than any other machine. The CDTM models are tapping machines with the necessary components for conversion to drilling machines. The CDTM1100 is a TM1100 with components for converting to a DM1100. The CDTM2100 is a TM1100 with components for converting to a DM2100. All these combination models feature Reed’s flip clamp. They utilize Reed DT series drill taps and Reed D series drill bits, hole cutters, heavy-duty hole cutters, and PVC shell cutters. Drill taps, drill bits, and hole cutters must be purchased separately. NPT adapters also available.
