Drill bit set AWTools AW42791 — 8 pieces, pack weight 130 g

AWTools AW42791 — 8-piece drill bit set supplied in compact packaging. The set includes eight drill bits made of chromium-vanadium (CrV) steel with a tungsten carbide tip, designed for use with standard and impact drills. Double-edge flute helix and grooved body help remove debris during drilling. These bits are intended for drilling in masonry, limestone, natural and artificial stone and are suitable for workshop and home tasks that require durable replacement or spare bits.

Advantages

The CrV steel construction offers strength and resistance to bending under load, while the tungsten carbide tip improves wear resistance and enables penetration into hard materials. A double-edge flute helix and groove design facilitate fast waste removal and reduce clogging, maintaining drilling efficiency. Compact, lightweight packaging makes the set easy to store and transport for on-site or home use.

Suitable for

• Drilling holes in masonry and brick
• Working with limestone and natural stone
• Drilling into artificial stone and concrete-based materials
• General workshop and home repair tasks requiring multiple replacement bits

How to use

Select a drill bit from the set appropriate for the required hole diameter. Secure the bit in the drill chuck according to the drill manufacturer’s instructions. When drilling masonry or stone, use an impact drill setting and apply steady, moderate pressure; allow the tungsten carbide tip to cut and withdraw periodically to clear debris. Keep the drill perpendicular to the work surface to ensure straight holes and reduce bit wear. After use, clean debris from the flutes and store bits in their packaging to protect cutting edges.

Usage recommendations

Use personal protective equipment such as safety glasses, dust mask and hearing protection when drilling masonry or stone. For longer bit life, avoid excessive side loads, let the bit cool between prolonged drilling operations, and use appropriate drill speed matching material hardness. Check compatibility with the drill’s maximum RPM and follow the drill tool manufacturer’s guidance.
