GARANT HB71 turning grade: extremely aggressive in stainless steels.

GARANT ISO-M grade family for ISO turning of stainless steels

Robust, sharp, one of a kind! The GARANT turning grades from the HB71 series stand out in comparative tests for stainless steel machining. The multilayer coating of the GARANT indexable inserts enables optimum cutting data and maximum reliability. We offer an unrivalled range of substrates and conditions, making the HB71 series a true all-rounder.

Go to HB71 range

Aggressive, strong and assertive

Dominant and uncompromising – like a shark in open waters
Maximum machining performance due to aggressive material removal

Robust and durable

Protective layer as armour: High wear resistance and long service life
Reliable and stable even under difficult conditions (e.g. with heavily interrupted cuts)

Precision in perfection

Clear lines – like the perfect contours of a shark
Precise shape for maximum dimensional accuracy, precision and control

Dynamism, efficiency and speed

Customised chip breakers for high feed rates and speeds
Highest productivity without any loss of quality

The HB71 grade family is optimally designed for machining stainless steels.

With precise coating concepts – from classic CVD coatings with TiCN and Al₂O₃ to innovative AlTiSiN PVD coatings – the HB71 series covers the entire range of applications.

From continuous cuts with high heat and wear resistance (HB7120-1) to universal applications with improved edge toughness (HB7130-2) to heavily interrupted cutting conditions where maximum toughness and process reliability are required (HB7140-2). The substrate and coating properties guarantee maximum reliability – even under difficult conditions.

GARANT HB7120-1

For consistent cutting conditions
For high productivity requirements
For stable machining conditions
Optimised heat and wear resistance

GARANT HB7130-2

For continuous cutting conditions and slight interruptions in cutting (scaling, uneven material,
saw cuts)
For moderate/high cutting speeds
The new first choice for turning stainless steels

GARANT HB7140-2

For heavily interrupted cutting conditions
For unstable machining conditions
For low/slight cutting speeds

PVD coating offers impressive process reliability – even with unstable component conditions and severely interrupted cutting conditions. In addition to machining conventional stainless steels, it also enables efficient machining of difficult-to-cut duplex steels, delivering excellent and reproducible results.

Positive inserts 5°/7°

VS

Light to medium machining of stainless steels. Also for materials that are difficult to machine. Sharp cutting edges for a soft cutting action.

VM

Distinctive chip evacuation geometry coupled with slightly positive cutting angle give the best chip evacuation. Main use for stainless steels.

VG

For roughing machining of stainless steels. Stable cutting edge version

VR

Stable easy-cutting geometry for single-sided inserts. For heavy-duty roughing machining of stainless steels.

VM chip breaker for machining stainless steels

Stainless steels and heat-resistant materials place the highest demands on tools and the machining process. The VM chip breaker was developed specifically for these materials. With a thermally optimised geometry, excellent chip control and reduced cutting pressure, it enables precise machining results. The chip breaker ensures targeted chip deformation, even with poor heat dissipation – this prevents built-up edges and protects the cutting edge.
