Hexagon Set 3 pcs Alpen-Maykestag APTM3 HM-Concrete — carbide-tipped concrete drill bits, hex shank

Hexagon Set 3 pcs Alpen-Maykestag APTM3 HM-Concrete — carbide-tipped concrete drill bits with hex shanks designed for drilling concrete and masonry. The three-piece set contains commonly used diameters for construction and repair work. Each bit is equipped with a hard-metal (HM) carbide tip for wear resistance and consistent cutting performance when penetrating reinforced concrete, brick or block. Hex shanks provide a secure hold in chucks and quick-change holders, reducing slippage during heavy-duty use and enabling fast bit changes.

Advantages

The carbide tips deliver high hardness and thermal stability to withstand abrasion and maintain sharpness over repeated use. Hex shanks ensure positive engagement with standard SDS-plus adapters, quick-change chucks and many handheld drill grips, improving torque transfer and reducing cam-out. The set format provides three versatile lengths/diameters to cover general-purpose tasks without needing single purchases. Construction-grade manufacturing and consistent tip geometry support straight drilling and predictable hole dimensions.

Suitable for

• Drilling holes in concrete, reinforced concrete and masonry
• Installing anchors, fasteners and through-fixings
• Electrical, plumbing and HVAC installation work in buildings
• Repair and renovation tasks requiring durable drill bits

Key specifications

• Tip material: hard-metal (HM) carbide
• Shank type: hexagon shank for secure grip
• Number of pieces: 3
• Intended material: concrete and masonry
• Compatibility: handheld drills, rotary hammer adapters and quick-change holders

How to use

Select a drill bit size appropriate for the anchor or fastener to be installed. Fit the hex shank securely into the drill’s chuck or quick-change adapter. When drilling concrete or masonry, use hammer-drill mode or a suitable rotary hammer function as recommended by the power tool manufacturer. Apply steady axial pressure, allow the carbide tip to cut, and clear dust periodically by withdrawing the bit. Start with a pilot hole for precise positioning if needed, and finish at reduced pressure to avoid chipping at the hole edge.

Usage recommendations

Wear eye protection, hearing protection and a dust mask when drilling concrete. Cool the bit by withdrawing and clearing dust; avoid excessive feed pressure that can shorten carbide tip life. Match drill speed and hammer action to material hardness and follow the power tool manufacturer’s guidance for best results.
