Floor grinder, concrete surfacer, single head grinder, or simply the grinder: whatever it's called on site, the Sept Tools floor grinder is brushless, quiet, made in Roanne, France, and built for the contractor who owns their kit rather than depending on the hire desk.

When a contractor is looking for a single head concrete grinder, the search usually turns up two worlds that don't quite fit: small hand-held sanders from the DIY aisle, and hire yards charging by the day. In between sits the machine you buy to keep for years: a walk-behind floor grinder that preps a slab before resin, strips old glue or paint, and surfaces a screed, shift after shift. That's where Sept Tools operates: brushless floor grinders made in France, quiet, IP65 rated, with dust captured at the source (H-class extraction) and after-sales support based at the factory with parts in stock. The Tapir XTT330 covers 80 to 120 m² per shift on standard concrete with a single operator; the Petit Potam and the Fouine XB165 handle edges, corners and smaller areas with the same diamond plates. Hiring a floor grinder typically costs £40-70 a day: once you're using one for more than a handful of days a year, investing in a machine that can actually be repaired changes the maths.
The machines below are selected for this application: brushless motors, dust captured at the source (class H extraction) and anti-MSD design. Quote within one working day.

View product The IU33 Longopac is our class H construction vacuum for HEPA H13 source capture. 1100 W, 25 kg, 65 l/s flow. Longopac bagging system: continuous sealed bag, emptying without reopening, eliminating dust release on disposal. Compatible with all our grinders, planers, wall chasers and core drills. Compliant with the crystalline-silica OEL of 0.1 mg/m³ (anticipating 0.05 mg/m³ in 2027). EN 60335-2-69 annex AA. Roanne, 48h after-sales.
View product The IU40 is a universal bypass motor cyclonic dust extractor designed for fine dust extraction on site. Its compact design facilitates transport and provides stable manoeuvrability. Equipped with a 22 m Longopac system, a ULPA+PTFE cartridge filter (18,500 cm2 filtration area) and an airflow of 340 m3/h, it is the ideal extraction solution for the Petit Potam and Fouine grinders.
View product The IU51 is a dual universal bypass motor cyclonic dust extractor. Extremely compact for easy transport and excellent handling, it is ideal for confined spaces. Its automatic filter cleaning system guarantees continuous maximum efficiency. Equipped with 2 ULPA+PTFE cartridges (22,000 cm2), an airflow of 340 m3/h and the 22 m Longopac system. Compatible with the Petit Potam, Fouine and Castor.
A single head concrete grinder typically hires for £40-70 per day depending on disc diameter. Once you're using one for more than a couple of weeks a year, buying a durable brushless machine works out cheaper, without depending on a hire firm's availability or the condition of a shared machine. The investment pays for itself over the motor's working life, 14 times that of a brushed motor.
No brushes, no commutator: full torque is maintained on dense areas, with no loss of power on reinforced concrete or hard laitance, and IP65 sealing against abrasive dust. Where a brushed motor burns out after 1,500 hours, the brushless motor runs 20,000 hours with no internal wear parts.
Grinding a concrete floor releases crystalline silica, covered by HSE silica dust rules on construction sites. Sept Tools floor grinders connect to the range's H-class extraction units (IU33 Longopac, IU40, IU51, IU81) with HEPA H13 filtration: dust captured at source, sealed bagging, and a machine built for compliance.
Design and assembly in France, standard parts kept in stock, national after-sales diagnosis within 48 working hours, repair once the quote is approved. A Sept Tools floor grinder gets repaired and keeps working: exactly what a contractor investing in their own fleet is looking for.
Occupied site, live car park, indoors: no time restrictions.
Reference figure across the range, measured on benchmark machines: a full shift without RSI risk.
Abrasive concrete dust and washdowns: the machine takes it.
20,000 brushless hours versus 1,500 hours for a brushed motor.
Opens the surface porosity and creates an even profile to guarantee adhesion for epoxy resins and floor paints. Mechanical stripping of glue, paint and laitance with no chemicals, and dust captured via H-class extraction.
High points, ridges and uneven screed corrected before laying a floor covering. The Tapir covers 80 to 120 m² per shift; edges and wall bases are finished with the Petit Potam using the same diamond plates.
Stripping degraded resin, chewing gum and paint on a live site: the quiet machine works alongside ongoing operations with no time restrictions, where a noisy machine would force night work.
Plenty of contractors are still running a floor grinder bought ten or fifteen years ago. When parts become hard to find, switching to a French-made, repairable machine with parts in stock secures the fleet for the next decade.
