CAT CLASS: HQ-10302

Up to 8 in Concrete Scarifier and Planer

Up to 8 in concrete scarifiers remove hard coatings, adhesives, and trip hazards in a narrow working path suited to perimeter work, confined spaces, and access through standard doorways. This is the smallest class in the Concrete Scarifier and Planer ladder, positioned below the 14+ in size class. The compact cutting width makes this size the default choice for walls, columns, and areas where larger equipment cannot operate.

How to choose

Up to 8 in scarifiers are appropriate when working along walls, around columns, or in spaces where a wider cutting path cannot fit. Their narrow profile and maneuverability suit perimeter cleanup, doorway transitions, and confined-area coating removal. For open-floor production work or projects where speed is prioritized over access, the 14+ in Concrete Scarifier and Planer class offers a wider cutting path and higher material removal rates. Choose this size when access constraints dictate the working width, not when floor area is the primary challenge.

What this size handles
  • Removing epoxy coatings along warehouse walls and loading-dock edges
  • Scarifying trip hazards at doorway thresholds and transitions
  • Cleanup work around columns and structural penetrations
  • Coating removal in narrow aisles and between racking systems
  • Surface prep in corridors and confined mechanical rooms
  • Edge work where ride-on or larger walk-behind equipment cannot reach

Safety & operation
  • Dust shroud and HEPA-rated vacuum required for silica compliance during concrete work
  • Rotating cutters demand guarding and clearance from bystanders during operation
  • Kickback risk when encountering embedded metal or abrupt surface changes
  • Hearing protection necessary; carbide cutters on concrete generate high noise levels

Transport & logistics
  • Compact enough for transport in enclosed trailers or pickup beds
  • Walk-behind design; operators typically load via ramps or tailgate

Power & supply
  • Electric models require 115V or 230V single-phase power on site
  • Gasoline-engine versions available for outdoor or unpowered locations

Frequently asked
When does the narrow cutting width justify choosing this size over a 14+ in scarifier?
This size is appropriate when access width is the constraint—working along walls, through doorways, or around obstacles. For open-floor work, the wider class removes material faster and reduces project duration.
What depth of material can this size class typically remove in a single pass?
Most models adjust to approximately 1/4 in depth, suitable for coatings and minor surface correction. Deeper removal requires multiple passes or a larger, more aggressive machine.
Does this size replace a grinder for edge work?
Scarifiers remove material more aggressively than grinders but lack the precision for tight corners or delicate profiling. Both tools serve distinct functions in surface preparation workflows.
