Engineering Excellence
Industrial Demolition & Surface Chipping Chisels
DURO manufactures professional-grade hammer chisels and breaker steels specifically designed for severe concrete breaking, channel chasing, asphalt cutting, tile removal, and masonry renovation. Engineered to withstand high joule impact loads from SDS Plus, SDS Max, pneumatic, and electric heavy demolition breakers, DURO chisels deliver exceptional fracture resistance and extended working life.
Micro-Allloyed Steel
Forged from premium 40Cr and 42CrMo structural alloy steel to endure extreme torsional force and high-frequency percussion without fatigue failure.
Dual Heat Treatment
Precision-hardened working tips (HRC 52-56) maintain sharp cutting edges while resilient shank cores (HRC 45-48) prevent chuck breakage inside the hammer toolholder.
Shot-Peened Finish
Surface shot-peening relieves internal manufacturing stress and enhances micro-hardness, protecting tools against surface micro-fractures under heavy load.

Quality Assurance & Compliance
Audited Quality & Precision Manufacturing
Every batch of DURO hammer chisels undergoes strict dimensional control and hardness profile testing according to ISO 9001:2015 quality assurance protocols. Manufactured in state-of-the-art drop-forging facilities, DURO chisels are compliant with international DIN and ISO toolholder tolerances, ensuring a snug chuck fit that reduces wear on power tool strike bolts.
Procurement & Engineering FAQ
Frequently Asked Technical Questions
Expert guidance for global procurement managers, equipment hire fleets, and industrial distributors.
DURO hammer chisels are drop-forged from high-grade 40Cr and 42CrMo micro-alloyed structural steel. They undergo vacuum induction hardening and controlled tempering to achieve an optimal hardness ratio (HRC 52–56 at the working tip and HRC 45–48 at the shank drive end), preventing premature shank fracturing while maintaining long-lasting point sharpness.
DURO supplies standard shank configurations compatible with major international power tool brands, including SDS Plus (10mm), SDS Max (18mm), 19mm Hex, 28mm Hex, 30mm Hex, and standard collar pneumatic breaker shanks for heavy civil engineering applications.
Shot-peening induces compressive residual stress on the steel surface layer, effectively neutralizing micro-cracks caused by high-frequency impact cycles. This process increases fatigue strength by up to 35%, ensuring reliable operation in reinforced concrete and dense hard rock demolition.
