Drill bit geometry has several characteristics

The diameter-to-length proportion of the drill bit is normally in between 1:1 as well as 1:10. A lot greater proportions are feasible (e.g., “aircraft-length” twist bits, pressured-oil gun drill bits, and so on), however the greater the proportion, the higher the technological obstacle of creating great.

α Alpha —- Lip Relief Angle

β Beta —- Wedge Angle

γ Gamma —- Land Angle

σ Sigma —- Point Angle

ψ Psi —- Chisel Edge Angle

 

The best chisel edge angle between 52 ° – 58 °

The above angle depends on the processing material.
