The contractor I work for uses Lennox auger bits (white with a blue wolf) for our primary auger bits all 1 1/8 or 7/8 we do log homes as our primary contract so 4-5 feet in 1 continuous hole is usual. Sharpen only when hit a spike or sinker nail!!
we are still looking for a good holesaw bit or forstener bit set. We have recently gone to the super hawg as well- love that machine, it replaced the regular hawg hands down, a 2-3 minute hole is now 45-55 sec. chips fly now!! annual hawg burn up at about 2 a year - superhawg has gone year and half only tore out 3 handles on the head.
