摘要：
The present invention relates generally to a twist drill useful for boring holes into wood, wood composites and other lignin-based materials. In particular, the invention relates in one form to twist drill having a rotational axis and comprising: a body portion having a flute running helically at a helix angle therealong, and a tip portion having a point, the point having a point angle, wherein the helix angle and point angle are both determined by reference to rotational axis, and the point angle is about equal to or less than the helix angle.
