Chisel for concrete MEGA SDS-Plus 17×250 mm (model 81703)

Chisel for concrete MEGA SDS-Plus 17×250 mm is a solid steel chisel with an SDS-Plus shank, 17 mm working diameter and 250 mm overall length. It is engineered for use with compatible SDS-Plus rotary hammers to perform chiselling, grooving and light demolition in concrete and masonry. The straightforward geometry and hardened steel construction provide reliable material removal for repair, installation and surface preparation tasks on construction sites and during renovation work.

Advantages

The MEGA concrete chisel combines a robust, heat-treated steel shaft with an SDS-Plus interface for quick, secure tool changes and stable operation. Its 17 mm diameter offers a balance between strength and access into narrow joints or grooves, while the 250 mm length gives sufficient reach into deeper sections without sacrificing control. The hardened tip maintains cutting and breaking performance over multiple uses, reducing downtime on repetitive tasks.

Suitable for

• Chiselling and breaking small to medium sections of concrete
• Creating grooves and channels in masonry for installation of utilities
• Removing tiles, adhesives and mortar residues during renovation
• Preparation of concrete surfaces for repair and patching

Key specifications

• Shank type: SDS-Plus compatible
• Working diameter: 17 mm
• Overall length: 250 mm
• Material: heat-treated steel
• Tip type: flat/straight chisel geometry for general-purpose chiselling

How to use

Insert the SDS-Plus shank into a compatible rotary hammer and ensure the retention mechanism engages before operation. Position the chisel on the work surface at the required angle and apply controlled impact force from the tool; allow the rotary hammer’s impacts to do the cutting and breaking rather than forcing the tool. For grooves or channels, move the chisel steadily along the line of work. Periodically withdraw the chisel to clear debris and inspect the tip condition. Wear appropriate personal protective equipment, including eye and ear protection, dust mask and gloves.

Usage recommendations

Use the chisel with rotary hammers rated for SDS-Plus bits and with impact energy suitable for masonry and concrete. Avoid using the chisel on hardened steel or reinforced concrete beyond its designed capability; when encountering heavy rebar, stop and switch to a dedicated rebar-cutting or more suitable demolition accessory. Store the chisel dry and clean to prevent corrosion and inspect before each use for visible wear or damage.
