Irwin IRW10502821 Blue Groove 4X Flat Bit 35mm x 152mm

The IRWIN Blue Groove 4X Flat Bits are designed to efficiently cut wood with a patented groove point and cutting edge that help cut rather than scrape timber. They deliver speeds claimed to be four times faster than standard flat bits, supported by a parabolic scoop that enhances control and facilitates removal of wood chips. Technical improvements include an increased relief angle from 12° to 17°, which aids clearance during drilling. The shank length is 152mm and the shank diameter is 10% larger than standard for added durability. The bit features a diameter of 35mm, delivering a robust cutting profile for wood projects demanding fast, clean holes while maintaining control during operation.
