SDS-plus drill bit Alpen-Maykestag F4 MB7 5–6×110 / 6–7–8–9–10×160

SDS-plus drill bit Alpen-Maykestag F4 MB7 5–6×110 / 6–7–8–9–10×160 is a combined set of short and long carbide-tipped bits designed for use with rotary hammers that accept SDS-plus shanks. The set includes smaller diameter short-length bits for shallow holes and a range of longer bits for deeper drilling tasks. These bits are intended for drilling into concrete, masonry and natural stone and are optimized for impact drilling where a robust tip geometry and chip removal are important.

Advantages

The flute and tip geometry provide reliable material removal and stable drilling performance in hard substrates. Carbide tips ensure wear resistance when working with abrasive concrete and masonry. SDS-plus shanks allow quick, secure connection to compatible rotary hammers and enable effective transmission of percussive force. Having both 110 mm and 160 mm lengths in the set covers a wider range of hole depths without requiring multiple separate purchases.

Suitable for

• Drilling anchor and fixing holes in concrete
• Installing electrical boxes and conduits in masonry
• Creating holes for plumbing and installation sleeves
• General renovation and repair tasks involving stone or brick

Key specifications

• SDS-plus shank compatibility for rotary hammers
• Tip material: tungsten carbide cutting head
• Flute design optimized for chip evacuation
• Set includes short 110 mm lengths for 5–6 mm diameters
• Set includes longer 160 mm lengths for 6–7–8–9–10 mm diameters
• Suitable for impact drilling (hammer mode)

How to use

Select the correct diameter and length for the required hole depth and application. Fit the SDS-plus shank securely into the rotary hammer’s chuck according to the tool manufacturer’s instructions. Use hammer drilling mode when working in concrete or masonry, apply steady axial pressure without excessive force, and allow the drill to do the cutting. Periodically withdraw the bit to clear dust and debris for better chip evacuation and to reduce heat build-up.

Usage recommendations

Use personal protective equipment such as safety glasses, hearing protection and a dust mask when drilling. For reinforced concrete, proceed slowly and check for rebar; if rebar is encountered, stop and use an appropriate metal-cutting drill or hole saw. Store the bits in a dry place to prevent corrosion of the steel shank and protect carbide tips from impact damage.
