What range of spindle rpm is sufficient for a flexible woodworking drill press? I've seen the range of 250-3000 rpm recommended to cover 1/16 - 1 inch twist and brad point bits in hardwood and softwood. Is this reasonable? I'm looking at a 5 speed (via belt changes) press that runs 400-3,000 rpm.
I trust this seemingly simple question could lead to expansive discussion of the requirements for special applications. However, I am interested in a general consensus on the minimal range necessary to handle "middle of the road tasks", using a range of bits but not necessarily extreme sizes (large), in both hard and soft wood.
Thanks.
