Rotary hammer accessory STHOR 23604 — 400 mm length, 18 mm diameter

STHOR 23604 rotary hammer accessory, 400 mm length with an 18 mm diameter shank, is an extension drill/chisel bit designed for use with compatible rotary hammers. This single-piece accessory provides increased reach for drilling and light chiseling tasks in masonry and concrete where standard-length bits do not reach. Check your rotary hammer's chuck or connection system for compatibility with an 18 mm cylindrical shank before use.

Advantages

The 400 mm length allows deeper penetration into walls and structures without changing the tool position, reducing time spent repositioning. An 18 mm diameter shank ensures a stable fit in rotary hammers that accept this common size, improving drilling straightness and control. The one-piece construction offers simplicity and reliable alignment during operation. The accessory is suitable for repeated use in construction environments when matched to an appropriate tool and application.

Suitable for

• Drilling deep holes in masonry and concrete where extended reach is required
• Accessing tight or recessed drilling positions without repositioning the tool
• Light chiseling or removal of material in renovation and repair work

How to use
