Wall sawing, also known as track sawing utilises a blade consisting of a circular steel core with segments containing synthetic diamonds laser welded to the outer edge of the blade. This diamond blade is attached to a motor head which is mounted on tracks.
Power options for wall sawing can be either hi-frequency electric or hydraulic diesel powered. Maximum cutting depth achievable using a wall saw is slightly over 1000mm deep.
The corners of an opening after wall sawing are not cut through unless the opening is cut past the connecting cut line. This is due to the use of round diamond blades. Where over cutting needs to be prevented, or represents a structural issue, core holes are drilled in the corners to complete the penetration.
Wall saws are known for their cutting precision, as they are able to achieve accurately sized and fixture ready penetration on completion. Wall sawing is also capable of cutting flush against other surfaces as well as producing bevelled or chamfered edges.
Since wall sawing operation is automated by way of a motor travelling along a fixed track operated via remote control, they are also perfect for cutting concrete which is heavily steel reinforced.
Versatility is yet another benefit of wall sawing as the tracks of the wall saw can be mounted anywhere, be it to the floor, wall, or ceiling (inverted cutting), and at any angle or degree of tilt.
For example, when cutting a doorway penetration, the base and side cuts can be completed using a hand saw and/or ring saw, yet the cut above the head cannot as it is unsafe to use a hand held saw above shoulder height. Whereas the tracks of a wall saw can be safely mounted above shoulder height and the penetration completed by way of wall sawing.
Wall saws are driven either via hi-frequency electric or hydraulic power producing zero fumes during operation. Wall sawing is perfect for indoors application as well as confined spaces where ventilation is an issue. Another benefit of hi-frequency electric is its light weight making it more versatile for hard to reach, restricted areas. Whilst hydraulic is ideal for cutting near water such as sea walls.
Wall sawing produces minimal noise, dust, and debris making it a perfect cutting solution for in or around occupied spaces where noise in particular is an issue.
