Tools for highest expectations!
New milling system 9W4 - high milling depths with maximum stability!
High-performance tool system with 12 cutting edges for groove and slot milling with milling depths up to 16.5 mm!
The system consists of anti-vibration carbide and steel toolhoders with internal coolant supply and milling inserts with 12 cutting edges with cutting widths from 0.5 mm and up to 6.0 mm.
Thanks to high-performance toothing technology from Kaestner-Tools, torsion at the insert-holder interface is effectively counteracted and the insert sits very stably in the insert seat. This results in high torques and feeds are possible, a higher cutting performance is achieved and ultimately main times are reduced.
Milling inserts:
The milling inserts are available in cutting widths between 0.5 mm and 6.0 mm and are subdivided as follows:
- Cutting widths 0.5 mm /1.0 mm: G geometry without corner radii
- Cutting widths 1.5 mm / 2.0 mm / 2.5 mm / 3.0 mm: GY geometry with corner radii on both sides
- Cutting widths 4.0 mm / 5.0 mm / 6.0 mm: GY geometry with corner radius on one side and additional 45° chamfer for cutting division
Tool holders:
- Carbide, with internal coolant supply, with shank diameter 16.0 mm and with L2 dimensions of 60.0 mm / 90.0 mm / 120.0 mm. Shank according to DIN 6535 HA.
- Steel, with internal coolant supply, with shank diameter 20.0 mm and an L2 dimension of 32.0 mm. Shank according to DIN 1835 A.
