Drill bit Luna 8 x 110 mm SDS‑Plus four‑cut FCH for rotary hammers

Luna SDS‑Plus four‑cut FCH drill bit, 8 x 110 mm, is made for use with SDS‑Plus rotary hammers to perform efficient drilling in concrete, masonry and natural stone. The four‑cut tip geometry improves chip evacuation and reduces drilling time compared with conventional tips, making this bit suitable for through holes and shallow anchor holes where precision and repeatable performance are required.

Advantages

The four‑cut FCH tip delivers faster penetration and improved dust and chip removal during hammer drilling. Compatibility with SDS‑Plus chucks ensures secure retention and easy bit changes. The 8 mm diameter and 110 mm length offer a balance between reach and rigidity for typical anchoring and fixing tasks. The bit is manufactured to provide consistent hole size and stable drilling behaviour under continuous use.

Suitable for

• Drilling anchor and through holes in concrete and masonry
• Installing wall plugs, anchors and fastenings
• Light to medium professional construction and renovation work
• Hammer drilling in natural stone and brick

Key specifications

• Tip geometry: four‑cut (FCH) for improved chip removal
• Shank type: SDS‑Plus for rotary hammers
• Diameter: 8 mm
• Total length: 110 mm
• Typical use: hammer drilling in concrete, masonry and stone

How to use

Fit the drill bit into the SDS‑Plus chuck until it locks in place. Select the hammer drilling mode on the rotary hammer and apply steady axial pressure while keeping the tool perpendicular to the work surface. Start with a pilot position and let the tool’s hammer action and the four‑cut tip do the cutting — avoid excessive lateral forces that can shorten bit life. For through holes, withdraw the bit periodically to clear dust and chips and to allow cooling.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, dust mask and hearing protection. Match drill speed and pressure to the substrate: moderate pressure for reinforced concrete and steady pressure for softer masonry. Replace the bit when wear affects cutting performance or when the tip becomes rounded.
