#[[Image:brad.jpg|thumb|75px|right|Brad point]]Brad or Spur tip wood bits. These work best when the mortise is drilled before the draught hole, or have fresh wood to center the spur, otherwise they can be pulled off course. In fresh wood, they track very well and produce a relatively flat hole (with a point at the bottom from the spur), the flatness facilitates a precise fit with the stem tenon, while the spur point in the center of the hole can also provide an excellent start for centering the bit used to drill the draught hole. | #[[Image:brad.jpg|thumb|75px|right|Brad point]]Brad or Spur tip wood bits.
