Point angle: The point angle is the angle formed by the cutting edges at the tip of the drill bit. A smaller point angle is best for drilling into softer materials, while a larger point angle is better for harder materials.

Lip angle: The lip angle is the angle formed between the cutting edge and the surface of the drill bit. A larger lip angle creates a sharper cutting edge, which can improve accuracy and reduce the amount of force required to drill a hole.

Drill geometry refers to the design and shape of a drill bit, which is a cutting tool used to create holes in materials. The geometry of a drill bit affects its performance, including its cutting speed, accuracy, and ability to remove material.

Flute design: The design of the flutes affects the amount of material that can be removed and the speed of drilling. Flutes can be straight or helical and can have different widths and shapes.

Shank design: The shank of the drill bit can be straight or tapered and can have different diameters to fit different drilling machines.

Helix angle: The helix angle is the angle formed by the flutes, or spiral grooves, on the drill bit. A higher helix angle can improve chip evacuation and reduce the amount of heat generated during drilling.

The choice of drill bit geometry depends on the specific drilling application and the materials being drilled. Different geometries can affect the drilling speed, accuracy, and ability to remove material. It’s important to choose the right drill bit geometry to ensure the best performance and to extend the lifespan of the drill bit.
