Atlas Copco HB2200 Tool Chisel for Hydraulic Breaker Hammer
HUILIAN supplies replacement tool chisels for Atlas Copco HB2200 hydraulic breaker enquiries. HB2200 combines a 150 mm tool section with a 270 mm axial retaining-profile reference. The 111 mm section at the recess is also shown on HB3000, so measuring the outer diameter and the complete rear layout is particularly useful when distinguishing these two replacement tools. Send the model plate, serial number, old tool photos, required working tip and overall length for a quotation.
Atlas Copco HB3000 Tool Chisel for Hydraulic Breaker Hammer
HUILIAN supplies replacement tool chisels for Atlas Copco HB3000 hydraulic breaker enquiries. The HB3000 drawing pairs its 165 mm shank with a 319 mm retaining-profile reference and a 151 mm rear reference. Compared with the HB2200 drawing, the principal identification benefit is the larger outer section and different axial layout, even though both show a 111 mm recess section. Send the model plate, serial number, old tool photos, required working tip and overall length for a quotation.
Atlas Copco HB4200 Tool Chisel for Hydraulic Breaker Hammer
HUILIAN supplies replacement tool chisels for Atlas Copco HB4200 hydraulic breaker enquiries. HB4200 is identified by a 180 mm tool diameter and a 338 mm axial profile. Its 182 mm rear reference is longer than those marked on the other supplied HB drawings, providing a clear extra check when inspecting a removed shank. Send the model plate, serial number, old tool photos, required working tip and overall length for a quotation.
Atlas Copco HB5800 Tool Chisel for Hydraulic Breaker Hammer
HUILIAN supplies replacement tool chisels for Atlas Copco HB5800 hydraulic breaker enquiries. For HB5800, the reference drawing shows a 200 mm shank and a 410 mm axial retaining profile, the longest profile reference among the five supplied HB-series drawings. This makes the complete axial measurement a useful purchase check in addition to tool diameter. Send the model plate, serial number, old tool photos, required working tip and overall length for a quotation.
