Renovation electrical chases
Le problème
A full day with a chisel for one apartment: noise, dust, broken back.
Sept Tools
Desman chaser: two hours, maximum cleanliness, easier patching.
Sept Tools
Wall grooving for electrical and plumbing chases
French brushless wall chasers for straight, clean and reproducible electrical chases without bulky external extraction.
Wall chasing is the key operation in electrical and plumbing renovation. Every metre of recessed conduit goes through this step, which determines project speed and final patch quality. Too often, chasing is still done with pneumatic chisels, manual angle grinders or rough routers. The result is slow, loud, hazardous and dust-generating. Sept Tools offers a dedicated brushless wall chaser that transforms this operation into a fast, clean and accurate motion.

Méthode traditionnelle vs Sept Tools
×
Chisel / manual angle grinder
- 1 day for a standard apartment
- Excessive noise, neighbours and occupied site impossible
- Silica dust everywhere, OEL compliance impossible
- Irregular chases, slow patching
- Shoulder and back MSDs by end of week
✓
Brushless Desman chaser
- 2 h for the same apartment
- 60 dB(A), occupied site without nuisance
- IU33 Longopac: source capture, compliance respected
- Calibrated straight chases, fast patching
- 0.38 m/s² vibration, full day with no risk

Use cases
For which job sites?
Recessed plumbing
Le problème
Multilayer, PEX, copper: variable widths, multiple settings.
Sept Tools
Depth and width adjustment in seconds with no tool.
Low-voltage cabling
Le problème
RJ45, fibre, alarm, home automation: clean trace required for patching.
Sept Tools
Fine straight chases, invisible plaster finish.
Silica compliance
Le problème
EU silica limit 0.1 mg/m³: manual angle grinder unlawful in occupied dwellings.
Sept Tools
IU33 Longopac source capture: exposure divided by 50.
Outstretched arm strain
Le problème
Ceiling or serial chases: shoulders strained, cumulative fatigue.
Sept Tools
Scourpio exoskeleton: weight transferred to the belt.
Dense reinforced concrete
Le problème
Old load-bearing walls: blade overheating and machine stalling.
Sept Tools
Constant brushless torque plus dedicated diamond blades: stable pace.
Frequently asked questions
Your questions, answered
Do I need a dedicated vacuum?
Yes. To meet silica thresholds and keep the site clean, an IU33 Longopac or equivalent is required. A household vacuum has neither the airflow nor the filter rating.
What is the maximum chase depth?
The Desman chaser reaches 35 mm in a single pass, sufficient for nearly all standard ICTA conduits and plumbing tubes.
Can I chase reinforced concrete?
Yes, with appropriate diamond blades. On dense reinforced concrete, the throughput is roughly 30% lower than on brick or block.
Does the machine work for corners?
Chasing is done in straight runs. For corners, plan two intersecting chases. Plaster patching ensures continuity and conduit pull-through.
What is the equipment payback period?
For an electrician handling three renovations per month, the machine pays for itself in 4 to 6 months thanks to time savings and elimination of chisel, grinder and site vacuum overhead.
