## Long description

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

Usage recommendations
Verify compatibility of the 18 mm shank with your rotary hammer before purchase.
