Precision bone drill bit
An orthopedic drill bit includes a cutting head formed to include diametrically opposed cutting lips leading to a central point and away to a radiused periphery to center said bit. The drill includes flutes extending from a cutting end, said flutes having a dulled periphery to prevent out of round holes. The flute design increases in width progressively from the tip up the shank, to maintain an adequate and unrestricted space for chips to easily move upward, preventing the chips from being compressed into a smaller opening while maintaining the tapered depth of the flutes for strength.
1. An orthopedic drill bit comprising:
two flutes extending helically along a length of the orthopedic drill bit;
two relief surfaces diametrically opposed to one another and formed directly between the two flutes, the two relief surfaces each defining a cutting lip such that the cutting lips are diametrically opposed to one another and a radiused periphery formed at a junction between distal edges of the relief surfaces and an outside diameter of the orthopedic drill bit, the radiused periphery thereby being arranged to form a blended and radiused corner between each of the cutting lips and a respective edge of the flutes; and
a cutting head formed to include the diametrically opposed cutting lips leading to a central point arranged at a cutting end of the drill bit and away to the radiused periphery so as to center said bit.
2. The orthopedic drill bit of claim 1 , wherein a width of the flutes changes downstream from the cutting end to promulgate bone shard exit.
3. The orthopedic drill bit of claim 1 , wherein a width of the flutes increases downstream from the cutting end to promulgate bone shard exit.
4. The orthopedic drill bit of claim 1 , wherein a drive end of the drill bit opposing the cutting end comprises an AO quick connect coupler fixedly attached thereto.
