Product Description
The YG-1 G8A28 series X5070 Blue ultrafine micrograin carbide cutter has 2 flutes and a plain shank. These slot drills have a ball nosed end for high precision 3D machining. They range in diameter from 0.1mm-12mm. The X5070 range is designed for ultra-performance machining of steels, heat resistant steels and hardened steels up to HRc70. The nanograin substrate and silicone based coating allows for dry machining up to temperatures of 1400°c.
- Nanograin carbide substrate with blue silicone based coating.
- Dry machining in steels and hardened steeld < HRc70.
- Suitable for machining at extreme cutting speeds.
- High abrasion resistance with a mirror surface finish.
- Strong negative land provides tool strength for high hardness machining.
- Ultimate tool life.
- Can cope with extreme heat (up to 1400°).
- High Speed Roughing & Finishing.
- Designed for high precision milling operations.
- To achieve the maximum performance from this tool, we recommend using a high performance tool holder (Hydraulic chuck, shrink chuck, HP3/GSK or power milling chuck).
