Drill bit, Alpen-Maykestag Combi Set SDS-plus 7 mm (MPN 100007100)

The Alpen-Maykestag Combi Set SDS-plus 7 mm drill bit is designed for use with SDS-plus rotary hammer systems. It has a 7 mm diameter optimized for creating holes in concrete, masonry and similar substrates where an SDS-plus shank and percussive drilling action are required. The bit is intended for construction, installation and repair tasks that call for compatibility with SDS-plus chucks and consistent drilling performance.

Advantages

The combi set’s SDS-plus shank ensures secure retention and quick bit changes in compatible rotary hammers. The 7 mm diameter provides a balance between drill speed and hole precision for small to medium anchor and fastening applications. The carbide tip and flute geometry are configured to evacuate dust efficiently and maintain cutting performance in abrasive materials, supporting repeated use on masonry and concrete.

Suitable for

• Drilling anchor and fastening holes in concrete and block
• Installing conduits, pipes and electrical boxes in masonry walls
• Repair and retrofit work that requires SDS-plus compatibility
• Light to medium construction tasks where 7 mm holes are specified

Key specifications

• Shank type: SDS-plus compatible
• Diameter: 7 mm
• Intended materials: concrete, masonry and similar substrates
• Tip material: carbide cutting tip
• Primary use: rotary hammer drilling with percussion

How to use

Install the drill bit into the SDS-plus chuck of a suitable rotary hammer according to the tool manufacturer’s instructions until it locks in place. Select a drilling speed and percussion setting appropriate for concrete or masonry, apply steady axial pressure, and allow the hammer action to advance the bit. Periodically withdraw the bit to clear dust from the hole and avoid excessive heat build-up. Replace the bit when wear degrades drilling efficiency or hole quality.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, hearing protection and dust control measures. Match drill diameter and depth to the anchor or fastener specifications, and follow the rotary hammer manufacturer’s guidance for correct settings and maintenance.
