Eterna diamond blade 'cuts noise exposure'


DIAMOND blade specialist Eterna is offering contractors the opportunity to reduce noise exposure and cost in concrete sawing with the introduction of a 900 mm diameter silenced blade for dry cutting.

The firm, which claims the largest range of silenced blades in the world, said its blades will reduce noise output by 3 dB over standard blades, while the super-silenced version, which features a copper insert, reduces it by 13 dB.

According to Eterna's Daniel McGill, using such a large dry blade will avoid the need to call in a subbie for wet cutting.

He said: 'On top of the savings in cost and reduced noise exposure, to comply with the recent Noise Regulations, you could save two million gallons of water a year by not having to have wet cutting.' He added that adding dust extraction could cut costs still further, by eliminating the need for water suppression and clean up.

He said: 'That could save a contractor a further £250 a day.'
