Description
Water Main Drilling Machine Kit for 3/4" to 2" AWWA and NPT Corporation Stops
Overview
Installing a water service line starts with drilling through the pressurized main. The Reed DM2100UNIVERSAL is a water main drilling machine that cuts through cast iron, ductile iron, C900 PVC, and PE pipe via a corporation stop and service saddle. This 14-piece kit covers both AWWA and NPT threads from 3/4" to 2", so one package handles any corporation stop thread standard.

Key Features of the Reed DM2100UNIVERSAL Drilling Machine
- AWWA and NPT Thread Coverage. The Universal kit includes six corporation adapters and two thread converters, covering both AWWA and NPT standards from 3/4" to 2". One kit handles any corporation stop thread type encountered in the field.
- Cast Iron, Ductile Iron, PVC, and PE Compatibility. The DM2100 drills through cast iron, ductile iron, C900 PVC, and PE water mains. D Series drill bits handle metal pipe, while shell cutters are used for PVC and PE.
- 250 psi Design Pressure Rating. The valve and chamber are rated to 250 psi. Recommended operating pressure for drilling into pressurized mains is 90 psi.
- 13.2 lb Base Machine. The base drilling machine weighs 13.2 lbs without adapters or case. The complete 14-piece kit ships at 60.0 lbs in a carrying case.
- Manual or Power Drive Operation. The machine operates by ratchet handle through a 13/16" square shaft. A power drive adapter (TMPDA, sold separately) connects motorized drives for faster operation.
AWWA and NPT Compatibility
The "Universal" designation separates this water main drilling machine from the standard DM2100 (09312), which includes only AWWA corporation adapters. The DM2100UNIVERSAL adds NPT corporation adapters for 1-1/2" and 2", plus NPT-to-AWWA converters for 3/4" and 1". Utility crews working in areas with mixed thread standards can carry one package instead of sourcing separate adapter sets for each job.
The full adapter set:
- DMCA75: 3/4" Corporation Adapter
- DMCA100: 1" Corporation Adapter
- DMCA150: 1-1/2" AWWA Corporation Adapter
- DMCA200: 2" AWWA Corporation Adapter
- DMCA150NPT: 1-1/2" NPT Corporation Adapter
- DMCA200NPT: 2" NPT Corporation Adapter
- DM75: 3/4" NPT-to-AWWA Converter
- DM100: 1" NPT-to-AWWA Converter
The DM2100UNIVERSAL also includes the DMHSA hole saw adapter for 1-1/2" and 2" drilling, two 3" drill bit extensions (DMDA75 and DMDA100), and two drill bit extenders for 3/4" and 1".
Applications
The DM2100UNIVERSAL is a water main drilling machine for installing and maintaining water service connections on pressurized mains:
- New water service line installations on cast iron and ductile iron distribution mains
- Service connections on C900 PVC and PE mains using shell cutters
- Municipal water system maintenance and emergency repair
- Main extensions requiring lateral connections under pressure
- Jobs where both AWWA and NPT corporation stops are specified

Frequently Asked Questions
Reed DM2100 vs Mueller EZ-TAP drilling machine: what is the difference?
The Mueller EZ-TAP and Reed DM2100 both drill corporation stops from 3/4" to 2" on pressurized water mains. The EZ-TAP has a 300 psi working pressure and 9.5-inch travel. The Reed DM2100 has a 250 psi design pressure with 90 psi recommended operating pressure, and the Universal kit includes adapters for both AWWA and NPT thread standards.
What pipe materials can the DM2100 drilling machine handle?
The DM2100 drills through cast iron, ductile iron, C900 PVC, and PE water mains. Metal pipe requires D Series drill bits or carbide-tipped hole cutters with tapping compound. PVC and PE pipe use shell cutters applied to the outside diameter, with no pilot drill needed for PVC.
What drill bits and cutters work with the Reed DM2100?
For 3/4" and 1" drilling, the machine uses Reed D Series bits (D688, D875, D938) with the included drill adapters. For 1-1/2" and 2" drilling, hole saws mount to the included hole saw adapter with a 1/4" pilot drill. Shell cutters (PL688 through PL1750) are available for PVC and PE.
How do you drill a water main under pressure?
Clean the pipe surface, mount a service saddle, and install the corporation stop into the saddle threads with the valve open. Attach the drilling machine to the corp stop, feed the drill bit down to the pipe, and turn the ratchet handle clockwise while advancing the feed housing. Open the flush valve to clear chips, and after the drill passes through, release the star feed to retract the boring bar and close the corp stop.
What is the difference between the DM2100 and DM2100UNIVERSAL?
The standard DM2100 (09312) ships with AWWA corporation adapters for 3/4" to 2". The DM2100UNIVERSAL (09321) adds 1-1/2" and 2" NPT corporation adapters plus 3/4" and 1" NPT-to-AWWA converters. The Universal kit is the better choice for crews that encounter both AWWA and NPT corporation stops on water service installations.
