GND Grooving Series
GND Grooving Series
GND Brochure 2026

Features & Benefits:
High Rigidity Body
- Utilizing die steel and a one-piece construction to achieve stable machining by suppressing chattering not only in grooving but in turning, profiling and facing operations.
A variety of Chipbreakers
- GND series has a lineup of 10 different chipbreakers for different machining applications.

Insert Selection:
Chipbreaker for Cut-off Machining
CF Type:

- Lead angle of 10° – 15° for improved sharpness in cut-off machining.
- Asymmetrical chipbreaker design provides excellent chip control even in difficult to machine conditions.

GND Modular:

GND 90°:

Cutting Performance:
Eliminated Chattering
- High rigidity design reduces chattering up to 30% better than conventional tools.

Material: Cr–Mo steel
Holder: GNDL R2525M-220
Insert: GCM N2002-GG (AC530U)
Cutting Condition: svc=100m/min, f=0.10mm/rev, ap=20.0mm, Wet
Ensures both high rigidity and good chip evacuation performance
Material: Cr–Mo steel
Holder: GNDI R2532-T306
Insert: GCM N3002-GG (AC530U)
Cutting Condition: svc=100m/min, f=0.05mm/rev, ap=3.0mm, Wet
Product Offering by Application:








Items for GND Small Lathes Expanded

The lineup includes grooving widths of 1.25, 1.5, 2.0, and 3.0mm.
Reduces chattering and achieves high-efficiency machining
Reduces vibration during grooving while inheriting the high holder rigidity of the GND series.
Reduces chip control problems
To improve chip control under various conditions, we have newly added the GF Type to our wide lineup of chipbreakers.

Low Cutting Resistance Chipbreaker GF Type
1. Reduces chattering during cutting.
2. Ideal for machining using low-powered equipment such as small lathes.
3. Reduces adhesion to tools and achieves long tool life in machining of stainless steel, etc.
Achieves excellent chip control and reduced cutting resistance thanks to the sharp cutting edge design with a rake angle of 30°. Also achieves reduced frictional resistance through chip control with point contact.
