Chisel noise on occupied site
Le problème
Chisel at 100 dB(A) in occupied dwelling: complaints, time restrictions, lost contracts.
Sept Tools
Desman brushless 60 dB(A): no restrictions, permanent cohabitation.
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.
Measured performance
0
Sound level
Inhabited dwellings and occupied sites: no excessive nuisance.
0.38m/s²
Vibration
Measured on a straight chase cycle, well below the ELV.

Challenges and solutions
Technical challenges and answers
Irregular chase poor patching
Le problème
Manual angle grinder: chipped edges, variable width, double patching time.
Sept Tools
Desman 1600 W: 35 mm depth, calibrated width, fast patching.
Multi-section complexity
Le problème
ICTA, multilayer, copper sections: three different tools or constant resetting.
Sept Tools
Desman tool-free depth and width adjustment in seconds.
Grinder silica unlawful
Le problème
Angle grinder chasing: 300x OEL 0.1 mg/m³, immediate enforcement notice.
Sept Tools
IU33 Longopac HEPA H13 source capture: exposure divided by 50.
Serial RSI overhead
Le problème
Overhead or serial chases: shoulders strained, vibration 0.38 m/s² vs 8 m/s² from chisel.
Sept Tools
Scourpio exoskeleton: weight transferred to belt, vibration 0.38 m/s².
Stalling in reinforced concrete
Le problème
Old load-bearing walls: carbon blade overheats, machine stalls, blade breaks.
Sept Tools
Brushless 1600 W constant torque plus diamond blades for reinforced concrete: stable pace.
Use cases
For which job sites?
Apartment renovation electrician
Full apartment chases in 2 h instead of a full day with chisel. Residential and tertiary sector: 40 to 60 linear metres per shift.
New-build plumbing recessed
Wider chases for multilayer, PEX or copper on residential programmes. Desman sets width and depth in seconds: 30 to 50 linear metres per shift depending on section.
Office fibre and automation cabling
Fine clean chases for RJ45, fibre, alarm and home automation in offices and hotels. 50 to 80 linear metres per shift.
Industrial expansion joint work
Creating or refurbishing expansion joints and flexible sealants on industrial slabs and walls. Constant width across the full run, 20 to 40 metres per shift.
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.
