The larger cross section (58% more mass) of 8mm shank bits makes them considerably stronger than 1/4" shank bits, resulting in smoother, faster cuts with less chatter and greater safety. 7 piece set suitable for Super Jigs containing Leigh cutters 50-8, 60-8, 70-8, 75-8, 101-8, 112-8 and 128-8. Set is supplied with wooden storage box.
