Rotary hammer accessory STHOR 23594 — drill bit, 250 mm length, 14 mm diameter

STHOR SDS+ chisel model 23594 is a 250 mm-long masonry chisel designed specifically for tile removal and light chiselling tasks. The working tip measures 60×14 mm, providing a wide, flat surface for efficient undercutting and prying of ceramic and porcelain tiles, as well as for removing mortar and thin layers of masonry. The tool features an SDS+ shank that fits compatible rotary hammers, ensuring secure retention and fast, tool-free changes when used with appropriate power tools.

Advantages

The chisel’s flat 60×14 mm tip delivers broad contact for stable, controlled material removal, reducing concentrated impact and helping to avoid accidental tile breakage. The 250 mm overall length offers a balance between reach and control for both overhead and floor work. The SDS+ shank provides reliable coupling with rotary hammers that accept SDS+ tooling, improving impact transfer and reducing slippage during heavy-duty use. The hardened steel working end resists wear under repeated impacts and maintains edge geometry for consistent performance.

Suitable for

• Removing ceramic and porcelain tiles
• Chiselling mortar joints and thin masonry layers
• Preparing surfaces for repair or re-tiling
• Light demolition and renovation tasks using SDS+ rotary hammers

Key specifications

• Overall length: 250 mm
• Working tip dimensions: 60 × 14 mm (width × thickness)
• Shank type: SDS+
• Material: hardened steel working end (tool steel)
• Intended use: tile removal, mortar and thin masonry chiselling

How to use

Insert the SDS+ shank into a compatible rotary hammer and ensure it locks into position before switching on the tool. Position the flat blade edge under the tile or along the mortar joint at a shallow angle to begin prying or chiselling. Apply controlled, steady hammering strokes while maintaining a firm grip on the rotary hammer; avoid excessive leverage that could damage the blade or cause uncontrolled breakage of tiles. Periodically check the chisel tip for wear and dress or replace the tool if the cutting edge becomes excessively rounded or damaged.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, ear protection and gloves. Match the chisel to a rotary hammer that supports SDS+ tooling and select impact power settings suitable for tile and light masonry work. For prolonged use, allow the tool and machine to cool periodically and inspect the chisel for deformation or cracks before each job.
