Description

Champion Chisel CM99-19 6" SDS-Max Floor Scraper System with Sure-Lock Fasteners

The Champion Chisel CM99-19 6-inch SDS-Max floor scraper system shears bonded ceramic tiles, chips hardened thinset mortar beds, strips vinyl composition tile (VCT), and lifts stubborn carpet adhesives without damaging underlying concrete subfloors. Engineered with a heavy-duty forged alloy steel shank and a 6-inch wide flexible spring steel blade, this industrial demolition tool mounts directly into standard SDS-Max rotary hammers and demolition hammers set to hammer-only chipping mode. Outfitted with heavy-duty Sure-Lock mechanical locknuts that prevent bolt loosening under continuous hammer impact, it equips flooring contractors, demolition crews, and remodeling specialists with fast, fatigue-reducing surface preparation across large commercial and residential tear-out projects.

Best Used For:

  • Ceramic Tile and Thinset Bed Demolition: Fracturing and popping glazed floor tiles while scraping hardened modified thinset mortar down to clean concrete slabs.
  • VCT and Commercial Vinyl Flooring Removal: Peeling bonded vinyl composition tile, sheet linoleum, and rubber flooring layers rapidly in commercial spaces.
  • Carpet Adhesive and Coating Scraping: Lifting tacky carpet glue, dried mastic residues, and thin epoxy sealers from subfloors prior to new flooring installation.

Key Performance & Safety Features

  • Sure-Lock Fastener System: Mechanical all-metal locknuts and high-tensile bolts keep the scraper blade clamped securely under high-frequency impact vibration.
  • High-Flexibility Spring Steel Blade: 6-inch wide heat-treated blade flexes under load to slide beneath floor coverings while maintaining a sharp shearing edge.
  • Standard SDS-Max Drive Interface: Universal machined shank fits all commercial SDS-Max rotary hammers and demolition chipping guns without adapters.
  • Replaceable Blade Architecture: Worn or damaged scraping blades can be swapped out quickly on the jobsite to restore factory scraping performance.
  • Forged Alloy Steel Shank: Heavy-duty heat-treated shank body absorbs heavy rotational and axial impact energy without bending or shearing.
  • Efficient 6-Inch Scraping Width: Balances maximum surface area coverage per stroke with concentrated hammer impact force to lift stubborn adhesives.

What's Included

  • (1) Champion Chisel SDS-Max Floor Scraper Shank Assembly (CM99-19)
  • (1) 6" Replaceable Spring Steel Scraper Blade

Pro-Tip: Maintain a low 20-to-30-degree attack angle relative to the floor when stripping VCT or thinset; this keeps the flexible spring steel blade gliding flat along the concrete slab rather than digging into the subfloor.
