Review on Meich 10 45Mm Triangle Nitride Insulation by Christopher Wiggins

For the price and size this is the best of everything. 45mm = 1.772 inches. Most of these spiral lures have a maximum length of 1 3/8 inches and cost more than twice that. I used this to drill some 1 3/8" holes in the 1 1/2" EMT tubing so I could insert and weld the 1" tubing for the tree house railing system. When the drill bit on low speed and a small amount of cutting fluid, this drill performed better than the other two drills that were said to contain cobalt.
