If you want to bore large holes in wood you can choose from a huge variety of bits — and since there are so many choices, companies have to differentiate their products from the crowd. Taking their customer suggestions into consideration, Greenlee recently redesigned their E-Z Bore bits to drill cleaner holes faster.
Greenlee changed the spur geometry of their E-Z Bore bits, increasing the pocket depth and the spur height, to penetrate the wood more smoothly, remove chips faster, and eliminate splintering, all without clogging. They also added a quick-change hex shank to make it easier to switch bits and keep the bit from slipping under high loads.
Greenlee makes their new E-Z Bore bits from high-quality alloy steel for increased durability. Since they’re built to last, the self-feeding tip is replaceable and the cutting teeth can be resharpened.
Right now Greenlee is listing bits in 1″, 1-1/8″, 1-1/4″, 1-3/8″, 1-1/2″, 1-3/4″, 2″, 2-1/8″, 2-1/4″, 2-9/16″, 3″, 3-5/8″, and 4-5/8″ diameters. There’s no pricing information on the redesigned bits, but if they’re priced like the old ones, they’ll be $50 to $75 a bit.
