Drilling tools \ Technical introduction – solid carbide / HSSE drilling
grinding/geometry:
Typ
N tip angle: 118°
spiral angle 30°
cone polished section
cutting material:
Universal HSS steel cutting material, for alloyed and unalloyed steels up to 1000 N/mm , steel casting, cast iron
2
and iron alloys
Benefits:
Suitable for a wide range of applications thanks to the universal geometry design
Minimises tool costs
Can be put to flexible use on both conventional and CNC machines, even in unstable conditions
Low hardness, resulting in a high breaking strength
Grinding/geometry:
Typ
TLP cone polished section 130°
spiral angle 38°
point thinning type A
cutting material:
Universal HSS steel cutting material, for alloyed and unalloyed steels up to 1000 N/mm , steel casting, cast iron
2
and iron alloys
HSSE: HSS steel with 5% cobalt alloy with greater hot hardness for increased loads up to 1300 N/mm 2
Benefits:
optimised flute profile for drilling deep holes in unfavourable conditions, such as insufficient cooling and poor
chip removal
depths of up to 25XD can be achieved
special geometry for drilling long-chipping materials
deep hole profile for optimising chip removal at greater drilling depths without the need for venting
extremely good chip removal thanks to the size of the chipping space
