SDS-Max shank bit Unifix

What it is

The Unifix SDS-max shank drill bit (code 0647-140-540-01) is the professional solution for precise drilling in reinforced concrete, cement and high-strength building materials. Designed for electro-pneumatic hammers, it delivers consistent performance even in the most demanding applications on site or in the workshop.

An SDS-Max bit is a carbide-tipped bit for rotary hammers with an SDS-Max chuck, for large-diameter, deep holes in concrete and masonry.

What it is for

Used for drilling reinforced concrete, in hammer or rotary hammer mode and for drilling solid and hollow masonry, clay brick and blocks.

How to use it

Clean and lightly grease the shank, insert it into the chuck until it locks and select hammer drilling. Drill with the hammer held in line with the hole, letting the machine's weight do the work without pushing, and withdraw the bit frequently to clear the dust. If you hit a reinforcing bar, stop and move the hole; do not cool a hot bit in water.
