Bur sds-4plus 25.0 x 400/450 mm S&R (210002348)

Description

The S & R SDS-plus Zentro concrete drill is used for drilling large diameter holes in concrete, masonry and natural stone. When drilling holes deeper than 450 mm, it is necessary to pre-drill with a drill of a shorter length to a depth of at least 150 mm, then with a drill 450 mm long, then with drills 600 or 900 mm. The SDS-plus Zentro drill has: A dynamically stable design that provides reduced vibration during drilling, which significantly increases the productivity of drilling holes; A carbide tip with four cutting edges for fast and accurate drilling of large diameter holes; A reinforced two-channel spiral significantly increases drilling efficiency due to the rapid removal of slag from the hole and reduced vibration; Heat-treated surface with special polishing to reduce wear and increase the drill's resistance to internal stress during operation. The S & R SDS-plus Zentro concrete drill bit is suitable for hammer drills from 2 to 4 kg with an SDS-plus or two-slot chuck type.
