Differentiation between full, partial

Carbide grades: and semi-profile:

Grade Application Description

designation

• Good tensile strength

O N Universal use for steel up to < 55 HRC burr-free and true to DIN/ISO gauge.

• AlTiN, multi-layer PVD coating

Garant Specially adapted for stainless steels

M S

27 HB8125 Also suitable for lnconel

when used with cutting oil

Garant Uncoated

HU8315 N Ti Especially for aluminium

and titanium alloys

Partial profile threading inserts cover a

wide range of different pitches.

However, they do not produce true to gauge threads

according to DIN/ISO, since the profile radius

does not match the respective pitch.

• TiAlN, PVD coating

Holex Especially for steel and low-alloy Semi-profile threading inserts cut

M S

HBF20 stainless steels the complete profile and deburr the tips

• Fully sintered of the thread flanks. The external or

internal ⌀ is not cut with the profile.
