I'm having some trouble boring tapered mortises in some 1 5/8" hard maple with my drill press. I'm using the large LV Standard Taper Reamer. I can get about 75% of the way through, and then if I put enough pressure to cut, the drill press stalls, and if I lighten up the pressure, the bit just spins, gets hot and glazes the inside of the hole. Any idea whether a brace would work better? (I don't own one and probably should buy one anyway, but it would be good to know whether it might help in this case…)
