Product Overview
This heavy-duty chisel bit set features both pointed and flat heads for efficient demolition of concrete, brick, and masonry surfaces. Each bit has a 35 mm (1-1/8″) hex shank for secure fitting in electric jack hammers and SDS-Plus rotary hammers.
Key Features
  • Premium Material: Crafted from hardened 40Cr alloy steel to maintain edge sharpness and resist deformation under high-impact conditions.
  • Extended Reach: With lengths up to 400 mm (16″), these bits easily reach deep cavities and overhead surfaces.
  • Versatile Heads: Pointed chisels for initiating fractures and precise chip removal; flat chisels for scaling, tile removal, and surface smoothing.
  • Durability Options: Optional carbide-tipped variants provide enhanced hardness for abrasive or reinforced concrete.
  • Universal Compatibility: Designed for use with both SDS-Plus and SDS-Max systems across multiple rotary hammer drills.
Technical Specifications
Sizes include 35 mm hex shank chisels in 35 mm pointed and 35 mm flat widths at 400 mm length. 50 mm wide flat chisels are available for broader scaling tasks. Reinforced flute design and heat-treated bodies optimize chip evacuation and reduce vibration during prolonged demolition work.
Applications
Ideal for professional demolition, construction, and renovation projects. This chisel bit set reduces downtime with quick bit changes and durable performance on various tough surfaces.
? Frequently Asked Questions
Q: What materials can these chisel bits handle?
A: These bits are specifically designed for heavy-duty demolition of concrete, brick, stone, and general masonry surfaces.
Q: What type of steel are the chisels made from?
A: They are manufactured from high-grade hardened 40Cr alloy steel, ensuring maximum durability and resistance to deformation.
Q: Are these compatible with my hammer drill?
A: Yes, they are designed to be compatible with standard hex shank systems (35mm / 1-1/8"), as well as SDS-Plus and SDS-Max rotary hammers depending on the specific shank configuration.
Q: What is the benefit of the pointed vs. flat chisel?
A: The pointed chisel is best for breaking through hard spots and starting fractures, while the flat chisel is ideal for controlled scaling, removing tiles, and smoothing surfaces.
Q: Do you offer bits for reinforced concrete?
A: Yes, we offer an optional carbide-tipped variant that provides extra hardness and a longer service life specifically for abrasive or reinforced concrete work.
Q: What is the maximum length available?
A: While standard sets often include 400mm (16") lengths, we can provide extended lengths up to 1500mm for specialized deep-reach requirements.
