The Irwin Cordless Drill Bits have been designed for cordless low /min multi-purpose drilling. In tests they produced between 90-129% more holes per battery charge than leading competitors.

They have a four-facet ground carbide tip for lower drilling pressure and better centring and allow for combined drilling into wood and brickwork: the Cordless Drillbit is excellent for such drilling jobs - where you drill through wood into brickwork.

Only one drillbit is needed to do the job and will drill a wide selection of different materials like:

Brickwork
Ceramic Tiles
Breeze Block
Wood
Dry Wall
Gypsum Board
Limestone
Slate
Marble
Eternite
Plastics/Reinforced plastics.

Set contains: 4, 5, 6, 7, 8, 10 and 12 mm drillbit sizes.
