Drill bit cassette Alpen-Maykestag ATM 3-289 (model 28900003100) – set of masonry/drilling bits

The Alpen-Maykestag ATM 3-289 cassette contains a set of carbide-tipped masonry drill bits designed for use with hammer drills. Packaged in a compact cassette for secure and convenient storage, this set is intended to deliver consistent performance when drilling into brick, concrete and aerated blocks. The bits are optimized for percussive drilling action and are suitable for tasks that require clean holes for anchors, fixings and through-drilling in masonry materials.

Advantages

Carbide tips extend cutting life and maintain edge retention when working with abrasive materials. The cassette design provides organized storage and protection from damage, making it easy to transport and keep bits sorted by size. Bits are balanced for stable drilling and compatibility with standard hammer-drill chucks, offering repeatable hole quality and reduced breakage risk compared with ordinary steel bits.

Suitable for

• Drilling holes in brick and concrete for anchors and fixings
• Installing dowels and threaded anchors in masonry
• Through-drilling of blocks and structural masonry elements
• General renovation and construction site drilling tasks

Key specifications

• Tip material: carbide-tipped cutting edges for masonry
• Intended drilling mode: percussive/hammer drilling
• Storage: compact cassette for organized bit storage
• Compatibility: suitable for standard hammer/drill chucks
• Application materials: brick, concrete, aerated concrete and similar masonry

How to use

Select the correct bit size for the required hole diameter and secure it in the drill chuck according to the drill manufacturer’s instructions. Use the hammer-drill mode when penetrating masonry, applying steady axial pressure without excessive force. Start at low speed to seat the bit, then increase to the appropriate drilling speed while keeping the drill aligned with the intended hole axis. Periodically withdraw the bit to clear dust and debris and allow the tip to cool, improving chip evacuation and prolonging bit life.

Usage recommendations

Use appropriate personal protective equipment such as eye protection, hearing protection and a dust mask when drilling masonry. Match drill speed and hammer action to the material hardness; for reinforced concrete, use smaller incremental passes and check for embedded rebar before continuing. Store bits in the cassette to prevent damage and maintain tip geometry.
