Professional brushless floor grinders for screed preparation, industrial surfacing and polished concrete finishing, without sparking or overheating.
Concrete floor grinding determines the quality of every coating that follows: epoxy, polyurethane, bonded tile or polished concrete. A poor flatness or untreated high spots will compromise adhesion and shorten the life of the finish. Sept Tools offers a range of French brushless floor grinders that combine torque, reliability and operator comfort. Each machine is engineered to deliver a uniform result on large surfaces without harming the operator over the long term.
Acoustic comfort on occupied or indoor job sites.
Measured to EN 60745 on a standard grinding cycle.
Constant torque on hard concrete with no variation under load.
4,000 to 6,000 hours with no internal wear parts versus 600 hours brushed.
Nominal torque is held on hard concrete even on the densest zones.
Calibrated to the range, supplied in multiple grits for substrate hardness and finish.
Compatible with IU33 Longopac, IU40, IU51 and IU81 to meet crystalline silica OELs.
Pads and housings change in minutes on site without specific tools.
Flatness, hardness and existing coating condition assessment.
Tapir with grit 30 or 60 metal pad to open porosity.
Successive passes until the profile required by the future coating.
IU33 Longopac (up to 800 m²) or Turbo7 (beyond), source capture.
Cohesion measurement and validation for resin or coating installation.
Flatness, hardness and existing coating condition assessment.
Tapir with grit 30 or 60 metal pad to open porosity.
Successive passes until the profile required by the future coating.
IU33 Longopac (up to 800 m²) or Turbo7 (beyond), source capture.
Cohesion measurement and validation for resin or coating installation.
Epoxy applied on insufficient profile: delamination within 12 months, decennial warranty voided.
Tapir 1600 W plus calibrated diamond pad: reproducible CSP 3 to 5 profile, resin spec compliant.
The slightest grit defect appears under raking light on architectural polished concrete.
Variable speed 500 to 4800 rpm constant torque, progressive diamond then velcro passes.
Industrial slab out of spec: client refuses acceptance, costly remediation.
Tapir brushless 1600 W constant torque: tolerance achieved in a single pass.
Epoxy adhesives accumulated over 30 years: chemical strippers ineffective, schedule blown.
Aggressive diamond pad IP65: mechanical stripping 60 to 80 m² per shift.
Floor grinding without extraction: concentration 200x above 0.1 mg/m³, enforcement notice.
IU33 Longopac, IU40, IU51 and IU81 class H HEPA H13 connected as standard, source capture.
30 to 50 h per week: brushed motor lasts 600 h, replaced every 3 to 5 months.
Brushless x14+: 4,000 to 6,000 h with no service, IP65, parts stocked in Roanne.
Slab surfacing to meet forklift flatness tolerances in logistics specifications. The Tapir processes 80 to 120 m² per shift on standard concrete with a single operator.
Mirror finish through progressive multi-grit passes to expose aggregates. Premium interior architecture projects: 15 to 25 m² per shift depending on target finish.
Stripping of degraded resins, paints and tyre rubber before requalification. The Tapir clears level after level with one operator, 60 to 80 m² per shift.
Porosity opening and CSP profile for resin applicator decennial warranty. Sectors: food processing, pharma, data centres.
