- 4-facet point provides primary and secondary relief grinds to maintain edge strength but provide clearance for chip removal. It is self-centering which prevents wandering when starting the hole, and improves hole quality.
- 6-facet point is the most durable of points. The fifth and sixth facets form secondary drill point angles at the weak outside cutting edge corners. These additional angles reduce the acute angle to reduce corner breakdown or dulling, increasing time before sharpening is needed. The design is self-centering which prevents wandering when starting the hole, and improves hole quality.
- Cone relief point is similar to 4- and 6-facet drill points except for the infinite number of facets that provide clearance behind the cutting edges. Relief behind the cutting edges allows coolant to flow, chip evacuation, and heat dissipation.
- Conventional point is suitable for use across a wide range of materials, such as metals, wood, and plastics. This is the most common drill point.
- Notched point can withstand higher thrust loads and penetration rates than a conventional point. Good centering ability to reduce wandering when starting a hole. Commonly used in heavy web drills, they are good for drilling into tough alloys.
- Special point is a vendor-specific design that incorporates different aspects of drill geometry to increase performance in application-specific tasks.
- Split point (also called crankshaft) is self-centering which reduces wandering when starting a hole. This design minimizes chisel length, which reduces thrust force. The positive rake angle improves the chip-cutting ability at the center of the drill point.
- Thinned point reduces the width of the initial contact surface of the drill bit point. Reducing the width reduces the thrust force needed when drilling and helps reduce wandering when starting the hole. Improves chip evacuation and good for drilling tough material. It is often used on large diameter drills.
