Drill Bit Set ALPEN SDS+ F4 Box 3 pcs — diameters 6, 7, 10 mm; length 160 mm

ALPEN SDS+ F4 Box 3 pcs — diameters 6, 7, 10 mm; length 160 mm is a compact set of three SDS+ rotary hammer drill bits intended for drilling in concrete, masonry and natural stone. Each bit has a working length of 160 mm and a standard SDS+ shank for use with compatible rotary hammers. The set is supplied in a practical box that keeps the bits organized and easy to transport between job sites or workshops.

Advantages

The set provides reliable drilling performance in hard materials thanks to bits designed for hammer drilling action. Standard SDS+ shanks allow quick, secure bit changes and broad compatibility with SDS+ rotary hammers. The compact storage box protects the cutting edges during transport and keeps the three diameters readily available for common drilling tasks. Uniform working length across the set simplifies depth control when switching between bit sizes.

Suitable for

• Drilling anchor and fixings holes in concrete and reinforced concrete
• Preparing channels and openings in masonry walls
• Installing through-fittings and conduit entries in stone or block materials
• Routine construction and renovation tasks requiring SDS+ rotary hammer drilling

Key specifications

• Bit diameters: 6 mm, 7 mm, 10 mm
• Working length: 160 mm (each bit)
• Shank type: SDS+ compatible
• Intended materials: concrete, masonry, natural stone
• Quantity in set: 3 pieces

How to use

Insert the selected SDS+ bit into the rotary hammer’s chuck until it locks, ensuring the tool is switched off and disconnected from power before changing accessories. Select hammer drilling mode and apply steady pressure while keeping the drill aligned with the desired hole axis. For deeper holes, periodically withdraw the bit to clear dust and debris. After drilling, remove the bit by pulling it out of the SDS+ chuck with the tool powered down.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and dust mask when drilling. Match drilling speed and applied pressure to the material; allow the hammer action to perform the work rather than forcing the bit. For reinforced concrete, use a carbide-tipped bit and inspect bit condition regularly; replace if worn or damaged to maintain performance and safety.
