The EDCO ALR-4 air-powered chisel scaler is a 4-foot steel tool built for flooring contractors, restoration crews, and demolition teams who need to strip stubborn surface materials off concrete without hammers and hand chisels. The compact 4-foot length is easy to maneuver in tight rooms, closets, and stairwells while still delivering powerful, fatigue-saving chipping action.
Built for these jobs
- Tile and flooring removal - strip vinyl, ceramic, and quarry tile, linoleum, and carpet from concrete subfloors.
- Coating and mastic removal - chip off rubber coatings, waterproofing, fireproofing, paint build-up, and tile mastics.
- Demolition and abatement prep - remove roofing materials, insulation, and regulated materials (follow all applicable safety and disposal regulations).
- Ice and buildup removal - clear compacted ice and hardened debris.
Why this air scaler works
An extra-large piston drives 2,500 hits per minute for powerful chipping, removing up to 200 square feet per hour of 4-inch ceramic tile set in standard thin-set. A quick-change, hardened-steel tool chuck accepts dozens of chisel and scaler attachments, so one tool handles many materials. The ALR-4 runs on shop air, requiring only 6 to 8 CFM at 80 to 90 PSI, and ships with a 4-inch steel chisel.

Frequently Asked Questions
What is the difference between the ALR-4 and the ergonomic ALR-E scaler?
The ALR-4 is a 4-foot scaler that is compact and easy to maneuver in tight spaces, while the ergonomic ALR-E is a longer 5-foot model designed to keep the operator fully upright on large open floors. Both deliver 2,500 hits per minute and share the same quick-change chuck and air requirement.
How much air does it need?
The ALR-4 requires only 6 to 8 CFM at 80 to 90 PSI, so most contractor air compressors can run it. Match your compressor's continuous CFM rating for steady full-force performance.
What materials can it remove?
With the right attachment it removes vinyl, ceramic, and quarry tile, linoleum, carpet, roofing materials, fireproofing, rubber coatings, waterproofing, insulation, mastics, paint build-up, and ice.
How fast does it remove tile?
At 2,500 hits per minute the ALR-4 removes up to 200 square feet per hour of 4-inch ceramic tile set in standard thin-set. Actual speed varies with the material, the bond, and the attachment.
