Drill bit set MEGA model 16525 — cylindrical masonry/concrete bits 4, 5, 6, 8, 10 mm

MEGA 16525 is a set of cylindrical masonry and concrete drill bits in five metric diameters: 4 mm, 5 mm, 6 mm, 8 mm and 10 mm. The kit is intended for use with rotary and hammer drills and covers common sizes for creating anchor holes, mounting fixings and a range of general concrete and masonry installation tasks. The bits have a straight shank design suitable for standard drill chucks and are supplied as a compact set so you have the most commonly used diameters available on site or in the workshop.

Advantages

The MEGA 16525 set provides a practical selection of diameters for everyday drilling in concrete and masonry, reducing the need to change tools between common anchor and fixing sizes. Cylindrical straight shanks ensure compatibility with a wide range of rotary and hammer drills. The included sizes allow efficient work from small pilot holes to larger fixing holes without carrying multiple single bits. The set format helps to keep bits organised and accessible.

How to use

Select the bit diameter that matches the required anchor or fixing. Secure the desired cylindrical bit in the drill chuck, ensuring it is clamped firmly. For masonry and concrete, use a hammer or rotary hammer function where appropriate, apply steady pressure and drill at a controlled speed to avoid overheating. Withdraw the bit occasionally to clear dust and debris from the hole. After drilling, clean the hole of dust before inserting anchors or fixings.

Usage recommendations

Use appropriate personal protective equipment, including eye and ear protection and a dust mask, when drilling in concrete or masonry. Match bit diameter to the anchor or fixing manufacturer’s instructions. For deeper holes or hard concrete, periodically pull the bit out to remove debris and reduce heat build-up; use a hammer drill setting for reinforced or very hard materials.
