## Summary description

Bosch Hartmetall Beton-Spiralbohrer CYL-3 is a 12 mm diameter carbide spiral drill bit for concrete with an overall length of 300 mm and a cylindrical shank. Designed for rotary and rotary-percussion drilling in masonry and concrete, it provides wear-resistant cutting performance for professional and DIY drilling tasks where deep or through holes in concrete are required.

## Long description

Bosch 12 mm CYL-3 Hartmetall drill bit for concrete, overall length 300 mm, cylindrical shank is a carbide spiral drill engineered for rotary and rotary-percussion drilling in masonry and concrete. With a 12 mm cutting diameter and a 300 mm overall length, this bit enables drilling deep or through holes in reinforced and non-reinforced concrete where extended reach and reliable cutting performance are required.
Advantages
The carbide tip and spiral flute geometry are designed to provide high wear resistance and consistent removal of drilling debris, reducing clogging during deep holes. The long 300 mm overall length combined with the cylindrical shank ensures stable mounting in standard chucks and steady drilling performance. The CYL-3 geometry offers balanced cutting action for both rotary and hammer-drill modes, making it suitable for demanding concrete applications while maintaining dimensional accuracy of the hole.
Suitable for
 Drilling deep anchor and fixing holes in concrete and masonry
 Through-holes in reinforced and non-reinforced concrete
 Installation of pipes, conduits and cable passages requiring extended reach
 Professional and DIY tasks using rotary or rotary-percussion drills
Key specifications
 Cutting diameter: 12 mm
 Overall length: 300 mm
 Shank type: cylindrical shank for standard chucks
 Tip material: carbide (hartmetall)
 Drilling modes: rotary and rotary-percussion (hammer) drilling
 Flute type: spiral flute for chip removal
How to use
Secure the drill bit in the chuck of a compatible rotary or rotary-percussion drill, ensuring the cylindrical shank is fully inserted and clamped. Mark the drilling point and, if necessary, start with a pilot mark to prevent slipping. Use appropriate drill speed and moderate forward pressure; allow the carbide tip to do the cutting and avoid excessive force that can overheat the bit. For deep holes, periodically withdraw the bit to clear dust and chips from the hole to maintain cutting efficiency and prevent jamming.
Usage recommendations
Use personal protective equipment (safety glasses, dust mask, hearing protection) when drilling concrete. When drilling reinforced concrete, proceed slowly and reduce pressure on rebar sections. For extended drilling sessions, allow cooling breaks and clear debris frequently to prolong bit life.
