Choose an option to view item availability.
Stanley Powerbore bits have not been available for some years now. After many customer requests, we have made a long-brad bit to fill the void.
These bits have several advantages; an outlining spur ensures clean entry, the large throat avoids choking in green wood, and the long brad minimizes wander while letting you drill into wood at an oblique angle.
The long brad is also helpful in preventing blast-out, which is usually unavoidable with shaped wood unless you use a long-brad bit. With this type of bit you bore from one side until the brad exits, then complete the hole from the other side using the brad hole as a centering point.
All bits are 6 1/2" long and have 1/4" hex quick-change shanks. Suitable for use in a three-jaw brace.
These bits excel in green woods and softwoods, but are unsuitable for dry hardwood. They are the traditional choice of chairmakers and workers in green wood generally.
No, Lee Valley greenwood bits are designed for green wood and softwood; drilling dry hardwood dulls the cutting edges quickly and produces rough, torn holes. For dry hardwood, use a standard twist or Forstner bit instead.
Bore from one side until the center brad tip exits, then complete the hole from the opposite side using that exit point to center the bit. A backing block also helps, though it may not work on a shaped workpiece.
No, a 3/8" or larger freehand power drill is recommended instead of a drill press, since constant feedback on speed and feed rate is needed to prevent jamming.
Reverse the drill to back the bit out until the packed chips clear, then continue cutting. Avoid touching the bit right after it's freed, since friction can leave it very hot.
Use a fine file on the leading edge of the outlining spur and the leading edge of the throat chipper; a few strokes are enough to restore the edge.
