Description

Professional 4-Inch Turbo Segmented Diamond Cup Wheel for High-Speed Concrete Surface Preparation

The OX Tools OX-PCTB-4 is an industrial-grade 4-inch turbo segmented diamond cup grinding wheel engineered to execute rapid stock removal, surface leveling, and heavy coating elimination across concrete and masonry block structures. Driven by a premium abrasive matrix compound that balances aggressive material cutting with a controlled, uniform finish, this heavy-duty wheel features a dual-fit 0.87-inch bore system matching common commercial 7/8-inch and 5/8-inch spindle layouts. The structural steel chassis integrates dedicated cooling and dust removal channels to vent debris buildup rapidly under maximum torque parameters, preserving the alignment edge across wet dust-suppressed or dry structural aggregate grinding setups on professional angle grinders.

Best Used For:

  • Concrete Floor Leveling: Flattening uneven joint seams, rough aggregate high spots, and structural imperfections on cured concrete foundation pads.
  • Thick Coating Stripping: Grinding off old waterproofing membranes, industrial epoxy coatings, and mastic adhesives before floor profile refinishing.
  • Hardscape Masonry Smoothing: Dressing rough vertical brick masonry block boundaries or cast architectural stone pieces during layout building phases.

Key Performance & Safety Features

  • Turbo Segment Engineering: Angled continuous segment patterns maximize aggregate abrasion contact surfaces while supplying rapid, cool stock stripping.
  • Integrated Cooling Channels: Deep structural ventilation paths channel particulate dust away from the wheel face to prevent component clogging under load.
  • Dual Mechanical Fitment: Standardized 0.87-inch bore configuration includes a modular 5/8-inch reducer bushing ring to mount universally on commercial spindle shafts.
  • Premium Synthetic Diamonds: Expertly distributed industrial micro-diamonds maximize grain retention to extend tool life across high-tensile material tasks.
  • Wet or Dry Formulation: Hardened metallurgical matrix bond chemistry operates reliably under water-flushed suppression or continuous dry cutting lines.

What's Included

  • (1) OX Professional 4-Inch Turbo Cup Grinding Wheel (OX-PCTB-4)
  • (1) 7/8 In. to 5/8 In. Modular Reducing Adapter Bushing

Pro-Tip: When smoothing out broad vertical masonry block targets, keep the grinder chassis flat to prevent the cup rim edges from digging sharp trenches into the aggregate face. Allow the high-speed turbo diamonds to plane down high positions cleanly under standard tool pressure to secure a balanced flat layout finish.
