Expansion of the NOTCH-GRIP Inserts Line with Chipbreakers for Standard Market Pockets
Highlights
ISCAR is expanding the NOTCH-GRIP line for precision grooving and threading applications by adding new inserts with a chipformer. The new families are fully compatible with standard market pocket sizes.
Following the successful introduction of the Notch Grip line and market demand, ISCAR is adding new inserts with a chipformer.
Important features
- Excellent chip control on alloy & stainless steel
- Different edge configurations for radial & face grooving, profiling and threading
With the addition of the new inserts, a complete Notch-Grip line is now available.
Grooving Insert Features:
- Inserts with chipformers
- 1.00 – 6.35 mm (.039”-.250”) grooving width range
- Double-ended shallow grooving inserts
- Single-ended deep grooving inserts
- Inserts with a flat-top and neutral rake angle or positive rake angle
- Inserts with a full radius for grooving and profiling
- Inserts for external undercutting
The inserts are available in 2, 3 and 4 pocket sizes, in ISCAR’s versatile SUMO TEC PVD coated grades IC807 / IC808. Suitable for grooving and turning a wide range of materials at medium-tohigh cutting speeds.
Threading Insert Features
- Double-ended precision threading inserts for a large variety of the most
popular industrial threading profiles
- Inserts for internal and external threading profiles
- Inserts with full and partial profiles
- Inserts with a flat-top neutral and positive rake or with a chipformer
- Multi-tooth
- Regular and fine pitches
The threading inserts are available in ISCAR’s versatile PVD grade IC908. Suitable for threading a wide range of materials at low-to-medium cutting speeds.
Tools
All inserts can be mounted on existing standard market pocket tools.
In addition, ISCAR offers the following tools:
- External tools for double-ended deep grooving inserts
- External tools for shallow grooving and threading applications
- External tools for grooving and threading applications, for Swiss-Type machines
- External tools for undercutting applications
- Internal tools with coolant through, for grooving and threading applications
- Interchangeable heads for grooving and threading applications
- Steel shanks with coolant through for interchangeable heads
The new NOTCH-GRIP tools and inserts will enable us to introduce our advantageous products to end-users who currently use these standard tools.
