Chisel bit SDS‑MAX Dedra Dłuto szpicak 18×280 mm

Dedra SDS‑MAX chisel bit Dłuto szpicak 18×280 mm is a pointed chisel designed for use with SDS‑MAX rotary hammers. With an 18 mm shank diameter and 280 mm overall length, this chisel bit is intended for chiselling, grooving and controlled demolition in concrete, masonry and similar construction materials. The pointed tip profile concentrates impact energy for efficient penetration and material removal, while the SDS‑MAX connection ensures secure engagement with compatible tool holders.

Advantages

The pointed geometry of the chisel concentrates impact force to create precise chips and facilitate faster advance in hard materials. The hardened steel construction provides wear resistance under repetitive impact and reduces the need for frequent replacement. Compatibility with SDS‑MAX tool holders ensures stable retention during high‑torque and high‑impact operations, while the 280 mm length offers reach for deeper chiselling tasks without compromising control.

Suitable for

• Chiselling and shaping concrete and reinforced concrete
• Removing masonry mortar and making grooves in walls
• Controlled demolition of small sections and spot removal
• Preparing surfaces for anchors, pipes or cable runs

Key specifications

• Shank type: SDS‑MAX compatible
• Shank diameter: 18 mm
• Overall length: 280 mm
• Tip profile: pointed (spike) for concentrated impact
• Material: hardened impact steel suitable for masonry and concrete

How to use

Insert the chisel bit into the SDS‑MAX tool holder until it locks securely, following the rotary hammer manufacturer's instructions. Use the bit with the rotary hammer set to hammer or hammer‑with‑rotation mode as appropriate for the material and task. Apply steady pressure and control the tool position to direct impact energy to the work area; avoid excessive lateral bending of the bit. Replace the bit when wear or bluntness reduces effectiveness or when visible damage appears.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust control measures. Match chisel size and tip profile to the task — use the pointed chisel for concentrated removal and breakthrough operations. Ensure the rotary hammer and SDS‑MAX holder are maintained and used within the tool's rated impact energy and operating guidelines.
