Description
Extended-Range Combination Drilling and Tapping Machine for 3/4" to 2" Water Service Connections
Product Overview
Water service connections run from 3/4" residential taps to 2" commercial laterals, and crews handling both sizes need one machine for the full range. The Reed CDTM2100 is a combination drilling and tapping machine that taps 3/4" and 1" corporation stops while drilling up to 2" through service saddles, from a modular kit at 116.5 lbs in a rolling tote.
What's Included
The Reed CDTM2100 ships in a plastic rolling tote with everything needed for both tapping and drilling modes:
- Boring bar assemblies for tapping (3/4" and 1") and drilling (3/4" to 2")
- Threaded body, top chamber assembly, and feed assembly
- 3/4" and 1" corporation stop adapters and insertion tools
- 1-1/2" and 2" AWWA corporation stop adapters
- Hole saw adapter, drill adapters, PVC drill adapter, and adapter shank
- Bearing sleeve and knockout pin
- 13/16" ratchet wrench and hand tools
- 5 ft. chain and hook, saddle gaskets, 1/2" ball valve and nipple, tapping compound
Drill taps, drill bits, hole cutters, shell cutters, saddles, and chain extensions for pipe over 16" diameter are sold separately.

Key Features
- 3/4" to 2" Drilling Range. The DM2100 drilling module handles corporation stops from 3/4" through 2", doubling the drilling capacity of the CDTM1100. D-series drill bits, hole cutters, and PL shell cutters mount through the included hole saw adapter.
- 1-1/2" and 2" AWWA Corp Adapters Included. AWWA Corporation stop adapters for 1-1/2" and 2" drilling come standard, along with 3/4" and 1" adapters for both tapping and drilling. No additional adapter purchases are needed to cover the full size range.
- Shared TM1100 Tapping Platform. Tapping mode is identical to the standalone TM1100 direct tapping machine, handling 3/4" and 1" corporation stops on pressurized cast iron, ductile iron, and C-900 PVC water mains at up to 250 psi.
- Operator-Controlled Star Feed. The flip clamp engages and disengages the star feed for quick repositioning. Manual feed lets the operator feel resistance from the cutting tool, preventing overdriving on thin-wall pipe materials like C-900 PVC.
- Complete Rolling Tote Package. All boring bars, bearing assemblies, adapters, insertion tools, and hand tools fit in a single rolling tote. Manual ratchet operation is standard; a power drive adapter connects to the 13/16" square shaft for motorized drilling and tapping.
Tapping and Drilling Size Ranges
The CDTM2100 separates tapping and drilling into distinct size ranges, each with its own boring bar and adapter set. This combination drilling and tapping machine covers a wider spread of service line sizes than any single-mode Reed machine.
| Mode | Size Range | Cutting Tool | Pipe Materials |
|---|---|---|---|
| Tapping | 3/4" and 1" | DT series drill taps | Cast iron, ductile iron, C-900 PVC |
| Drilling | 3/4" and 1" | D series drill bits, hole cutters | Cast iron, ductile iron, C-900 PVC |
| Drilling | 1-1/2" and 2" | Heavy-duty hole cutters | Cast iron, ductile iron, C-900 PVC |
| Drilling (PVC/PE) | 3/4" to 2" | PL series shell cutters | C-900 PVC, PE |
Tapping drills through the pipe wall and cuts threads in a single pass, so the corporation stop screws directly into the pipe. Drilling cuts through the pipe wall via a corporation stop already installed in a service saddle. The CDTM2100 converts between tapping and drilling by swapping boring bars and bearing assemblies using only the tools in the kit.
With the DM2100 module, the CDTM2100 functions as a 2-inch saddle drilling machine for 1-1/2" and 2" connections, while the CDTM1100 maxes out at 1" drilling. Tapping capacity is identical between the two machines.
Applications
This water service drilling and tapping machine handles connections from 3/4" through 2" on pressurized mains:
- Residential water service taps at 3/4" and 1" on cast iron, ductile iron, and C-900 PVC distribution mains
- Commercial and institutional 1-1/2" and 2" saddle-drilled connections on municipal water systems
- Mixed-size projects where a single modular tapping and drilling machine covers both residential taps and commercial laterals
- PE pipe drilling using PL series shell cutters for 3/4" to 2" connections on polyethylene mains
- Utility departments standardizing on a single corporation stop drilling machine for all service line sizes

Frequently Asked Questions
What is the difference between the Reed CDTM2100 and CDTM1100?
Both are combination drilling and tapping machines that tap 3/4" and 1" corporation stops. The difference is drilling range: the CDTM2100 drills 3/4" through 2" using DM2100 components, while the CDTM1100 drills only 3/4" and 1" using DM1100 components. The CDTM2100 kit also includes 1-1/2" and 2" AWWA corp adapters and a hole saw adapter that the CDTM1100 does not have.
What pipe materials and sizes can the CDTM2100 handle?
In tapping mode, the machine works on cast iron, ductile iron, and C-900 PVC mains for 3/4" and 1" corporation stops. In drilling mode, it handles the same materials plus PE pipe (using PL shell cutters) for sizes from 3/4" through 2". This makes the CDTM2100 a practical drilling machine for ductile iron and PVC pipe across the full range of residential and commercial service sizes.
How do you drill a 2 inch water service connection with the CDTM2100?
Install a 2" corporation stop into a service saddle on the pipe, then mount the CDTM2100 chamber onto the open corp stop. Insert the appropriate drill bit or hole cutter through the hole saw adapter, advance the star feed to cut through the pipe wall, then retract the boring bar and close the corp stop. For PE pipe, use a PL series shell cutter without a pilot drill. Saddles, drill bits, and cutters are purchased separately.
What is included in the Reed CDTM2100 kit?
The package arrives in a plastic rolling tote with boring bar assemblies for both tapping and drilling modes, threaded body, top chamber assembly, feed assembly, 13/16" ratchet wrench, tapping compound, 5 ft. chain and hook, saddle gaskets, 1/2" ball valve and nipple, 3/4" and 1" corporation insertion tools and corp adapters, 1-1/2" and 2" AWWA corp adapters, hole saw adapter, drill adapters, PVC drill adapter, adapter shank, bearing sleeve, knockout pin, and hand tools. Drill taps, drill bits, hole cutters, shell cutters, saddles, and chain extensions for pipe over 16" are sold separately.
Can the CDTM2100 be used with a power drive?
Yes. The ratchet wrench connects to a 13/16" square shaft for manual operation, and a power drive adapter fits the same shaft for motorized drilling and tapping. The power drive adapter is sold separately and accepts drives from Reed, Mueller, Milwaukee, DeWalt, and Ridgid. The power drive speeds up both the drilling and tapping process, which is especially useful for larger 1-1/2" and 2" holes on thick-wall pipe.
