About this product
This Irwin 3.5 x 110mm drill bit is designed for cordless, low-speed multi-purpose drilling, offering around 10% extra battery life per charge compared with standard bits. Its four-facet ground carbide tip lowers drilling pressure and improves centring accuracy, making it suited to precise pilot holes and small fixings.
The bit copes with combined drilling, such as through wood into brickwork, meaning only one bit is needed for the job. It can be used across a range of materials including brickwork, ceramic tiles, breeze block, wood, drywall, gypsum board, limestone, slate, marble and plastics.
Overall length is 110mm with a flute length of 59mm.
