Drilling tools \ Technical introduction – solid carbide / HSSE drilling
grinding/geometry:
Typ
VA ƒ cone polished section 130°
ƒ spiral angle 35°
ƒ point thinning type C
ƒ increased core diameter
cutting material:
ƒ HSSE: HSS steel with 5% cobalt alloy with greater hot hardness for increased loads up to 1300 N/mm 2
advantages:
ƒ positive geometry specially developed for use in stainless steel and special alloys
ƒ special geometry with aggressive cutter design and free geometry for very smooth cutting

grinding/geometry:
Typ
X ƒ tip angle 130°
ƒ precision-ground cone polished section + combination of point thinning types A/B
ƒ cutting angle adjustment through type B point thinning element, ensuring a strong, stable cutting edge
ƒ straight main cutter
cutting material:
ƒ HSSE-PM steel offers highest level of wear resistance through powder-metallurgical steel
ƒ extremely dense, homogeneous structure
ƒ increased hardness and heat resistance
ƒ high level of wear resistance and cutting edge stability
advantages:
ƒ highest level of wear resistance and heat resistance through HSSE-PM cutting material and TiN coating
ƒ economic drill that closes the gap between a standard HSS drill and a VHM drill for medium-strength materials
and moderate batch sizes
ƒ high cutting edge stability and robust drill design thanks to cone polished section with type A/B point thinning
and optimised parabolic flute profile
ƒ high process reliability thanks to the homogeneous structure of the HSSE-PM steel
