Abstract
A drill bit having roughness areas in a flute to reduce debris clogging in the flute during drilling, reduce temperatures of the drill bit and material being drilled, and lubricate the drill bit during drilling among other features. The drill bit is useful to drill in many unique materials including mammalian bone to reduce or eliminate bone chips occluding the flute. The roughness areas evacuate the bone chips quickly and efficiently and generate a low temperature of the drill bit and drilled material.
Claims8
A drill bit, comprising:
- a body;
- a flute extending along a length of the body and having an area comprising a smooth portion;
- and
- a plurality of roughness areas formed in a surface of the flute and spaced from one another along a length of the flute and configured to reduce friction to debris formed in the flute during drilling and to hold lubrication, wherein the area of the smooth portion is greater than the plurality of roughness areas.
1 more element
A drill bit, comprising:
- a body;
- a flute extending along a length of the body and having an area comprising a smooth portion;
- and
- at least one roughness area formed in a surface of the flute and configured to reduce friction to debris formed in the flute during drilling and to hold lubrication, wherein the area of the smooth portion is greater than the at least one roughness area,
- wherein the at least one roughness area is comprised of a band that is transverse to a length of the flute.
