Sharpening angles and Point shapes

Drill bits are not all the same. Special materials and the different applications need different cutting angles and point shapes. Refer to the table below to learn more about point shapes and the lip angles.

Relieved cone, 118 deg  Split Point AC, 118 deg  Split Point C, 130 deg  Centering point - 180 deg 

Relieved cone,
118°

Split Point AC,
118°

Split Point C,
130°

Centering Point-Shape E, 180°

Universal point-shape for a lot of drilling applications in steel and iron, non ferritic-materials, plastics and other materials. Point-shape with increased performance and very good centering. This point shape is being used for all industrial drill bits. Special point-shape for stainless steels
and special materials.
Special point-shape for spot weld drills.
Strengths
HIGHLY ACCURATE special shape, drills without center-punching
BREAK RESISTANT thanks to CNC heat treatment
INDUSTRIAL QUALITY suitable for NC machines
SELF-CENTERING thanks to special point shape
TEMPERATURE RESISTANT Up to 600° C drilling even with the highest thermal stress
FAST due to special drill grinding fast drilling progress and up to 50% less feed pressure required
