Since 2001, Cangzhou Dean Safety & Special Tools Co., Ltd. has been a leading manufacturer of professional demolition and construction tools. Our Heavy Duty Flat Chisel (18mm Shank, 400mm Length) is engineered for maximum impact and longevity, making it an essential tool for concrete, masonry, and stone breaking applications. With an annual export value exceeding US$100 million and a global footprint across North America, South America, Europe, Asia, Africa, and Oceania, we bring unmatched quality and reliability to every tool we produce.
This flat chisel features a drop forged carbon steel body that delivers exceptional strength and wear resistance. The 18mm hexagonal shank fits standard demolition hammers and breakers, while the 400mm working length provides optimal reach and leverage. The integrated safety guard ring protects the operator from debris and reduces hand fatigue during prolonged use. Whether you are a contractor, demolition specialist, or construction worker, this chisel offers the performance you need on tough job sites.
🔧 Product Features & Benefits
- Drop Forged Carbon Steel Construction: The chisel is forged from high-grade carbon steel, then heat-treated to achieve optimal hardness (HRC 48-52 typical) for superior durability and edge retention. This reduces the need for frequent sharpening and extends tool life.
- 18mm Hexagonal Shank: Designed for compatibility with most heavy-duty demolition hammers and pneumatic breakers. The hexagonal shape prevents rotation, ensuring stable and efficient energy transfer.
- 400mm Overall Length: Provides an ideal balance between reach and control, allowing you to work in tight spaces or at floor level without excessive bending. The length also helps absorb vibration and deliver precise strikes.
- Safety Guard Ring: A forged-in ring near the tip prevents the chisel from slipping through the tool holder and helps contain flying chips. This feature enhances user safety and reduces the risk of accidents.
- Flat Chisel Tip Design: The wide, flat cutting edge is optimized for splitting concrete slabs, removing tiles, chipping mortar, and breaking asphalt. It delivers clean, straight cuts with less effort.
- Customizable Options: Available in different surface finishes (black oxide, plain) and packaging (single unit, bulk, or with hex key). Contact us for custom lengths or material grades.

❓ Frequently Asked Questions
-
Q: What is the shank shape and size?
A: The shank is an 18mm hexagonal shape, designed for standard demolition hammer chucks that accept 18mm hex bits. -
Q: Is this chisel compatible with my Bosch breaker?
A: Most Bosch breakers with a 18mm hex chuck (e.g., GSH 16-30) will fit. Please check your tool’s manual to confirm compatibility. -
Q: What is the safety guard ring made of?
A: The guard ring is part of the forged steel body—it is integral to the chisel and not a separate add-on. It provides a physical stop to prevent over-insertion and catches debris. -
Q: Can I get different lengths or shank sizes?
A: Yes, we offer customization for length, shank diameter (e.g., 20mm, 22mm), and tip shape. Please contact our sales team with your requirements. -
Q: Does the chisel come with a warranty?
A: We provide a limited warranty against manufacturing defects. Warranty terms vary by order quantity; please inquire for details. -
Q: What hardness is the cutting edge?
A: Typically HRC 48–52, which balances toughness and wear resistance. Hardness can be adjusted for specific applications (e.g., softer for shock resistance, harder for abrasion). -
Q: Is this chisel suitable for breaking reinforced concrete?
A: Yes, for moderate reinforcement (rebar up to ~10mm). For heavy reinforcement, a point chisel or rebar cutter may be more effective. Always wear proper PPE. -
Q: Do you offer samples before bulk order?
A: Yes, sample orders are welcome. We can provide a single unit for testing before placing a larger quantity.
