Chisel (SDS‑Max) Hikoki 25×400 mm — Spade chisel long blade

Hikoki SDS‑Max Spade Chisel 25×400 mm is a long‑reach spade chisel designed for use with SDS‑Max compatible demolition hammers. The tool combines a 25 mm wide spade profile with a 400 mm blade length to enable efficient material removal, chipping and trenching in concrete, masonry and renovation tasks where extended reach is required. The hardened blade profile and SDS‑Max shank interface provide secure fitment and durability under repeated impact.

Advantages

The long 400 mm blade allows operators to reach deeper into joints, channels and confined areas without repositioning the tool frequently, improving work continuity. A 25 mm spade width produces pronounced chipping action and creates consistent trenches or channels in concrete and masonry. The SDS‑Max connection ensures reliable coupling to compatible demolition hammers and simplifies tool changes. The hardened steel construction resists deformation under heavy use and maintains cutting geometry longer than untreated blades.

Suitable for

• Creating trenches and channels in concrete and masonry
• Removing floor screed, mortar joints and plaster during renovation
• Chiselling at extended reach in deep fixtures and narrow openings
• Demolition tasks that require wide‑profile material removal

Key specifications

• Shank type: SDS‑Max compatible
• Blade width: 25 mm
• Blade length: 400 mm
• Profile: Spade (wide chisel) for material removal and trenching
• Material: Hardened steel blade designed for impact applications

How to use

Insert the SDS‑Max shank into the hammer’s tool holder and ensure it locks securely before switching the tool on. Position the spade edge against the work surface at the required angle and apply controlled pressure with the demolition hammer, allowing the tool’s impact energy to perform the cutting and removal. For prolonged chipping or trenching, maintain a steady feed and avoid excessive lateral bending of the blade. After use, clean off debris and inspect the blade edge for wear or deformation.

Usage recommendations

Use appropriate personal protective equipment such as eye protection, hearing protection and gloves. Select an SDS‑Max demolition hammer with impact energy and power matched to the application. Replace the chisel if the blade becomes significantly rounded or deformed to maintain efficient cutting and reduce the risk of tool failure.
