The EDCO 97100E is a 48-inch base-mounted concrete core drill rig built for plumbing, electrical, sign-installation, and welding contractors who need to cut clean cores all day. The rig pairs with a 20-amp Milwaukee motor on the largest column in the industry: a 3.5-inch extra heavy-walled square tube. A combination vacuum anchor base, brass wear strips, an ammeter control center, and premium large-diameter wheels round out the package. This SKU ships without a vacuum pump so the crew can pair its own pump.
Use cases
Plumbing and HVAC penetrations
Plumbing contractors use the 97100E for floor drains, 4 to 8 inch sanitary sleeves, and slab penetrations for HVAC duct and condensate. The 12-inch capacity covers the larger trunk sleeves without changing rigs.
Electrical and conduit installs
Electrical trades cut 2- to 6-inch cores for conduit runs, EMT sleeves, and floor boxes. The combination vacuum anchor base sets up fast on a finished slab so the install crew is not patching anchor holes after the run.
Railing, sign, and bollard installation
Steel-fabrication and sign crews drill 4 to 8 inch cores on a defined pattern for post anchors, bollards, and railing. The 48-inch column reach keeps the rig from limiting larger fixture footings.
Welding shops and concrete coring contractors
Specialty contractors who core concrete daily standardize on this rig family because the 3.5-inch column resists deflection through long, deep cuts and the 20-amp motor takes more rebar than the 15-amp variant before it stalls.

Frequently asked questions
How big a core can the EDCO 97100E drill?
Standard configuration drills cores up to 12 inches in diameter on a 48-inch column. The capacity is expandable in 2-inch increments with optional motor spacer blocks, so plumbing and railing-install crews regularly run 14-inch and larger bits without changing the column.
Does the rig need slab anchors?
It ships with a combination vacuum anchor base, which lets the operator mount the rig on a flat slab without drilling slab bolts first. For overhead, vertical, and uneven-slab work, the base accepts traditional through-bolt anchoring as well.
Why pick the 20-amp motor instead of the 15-amp variant?
EDCO offers both. The 15-amp Milwaukee will pull the most common 4- to 8-inch cores all day. Crews stepping into 10-inch and 12-inch bits, deep cores, or rebar-heavy slab work tend to specify the 20-amp variant for the headroom. The rig's electric circuitry and ammeter control center are matched to the motor at the factory.
Does this listing include a vacuum pump?
No. This is the NO Vacuum Pump configuration. The vacuum anchor base is included; the vacuum pump itself is sold separately so crews can pair it with whatever pump they already own. The complete package configurations are listed elsewhere in the EDCO core drill catalog.
What is the column actually made of?
The 97100E uses a 3.5-inch extra heavy-walled square tube column, the largest in the EDCO line and the largest in the industry at this rig class. Combined with brass wear strips and an easy-adjust carriage, it is designed to keep the bit true under bind and shaft load.
Discount Cleaning Products is an authorized EDCO dealer. The 97100E is the no-vacuum-pump configuration of EDCO's flagship base-mounted core rig and is supported by the EDCO replacement-parts network. US-based customer service can confirm the right motor (15- or 20-amp) and the right vacuum-pump pairing for the work you do.
