-
Grade: H01 – a general-purpose uncoated carbide grade suitable for a range of materials including non-ferrous and heat-resistant alloys
-
Coating / finish: Polished (in many catalog listings) for reduced built-up edge and smoother surface finish.
-
Cutting applications: Suitable for turning, milling and drilling – especially designed for efficient operations on non-ferrous metals and alloys while maintaining versatility for general engineering work
Why It’s a Best Seller
-
Less downtime: The robust negative geometry combined with MA chipbreaker ensures consistent performance and less frequent insert changes — keep your machine running.
-
Better surface finish: The polished face and optimized chipflow mean smoother grooves, fewer defects and less rework.
-
High wear resistance: Even in demanding materials the H01 grade offers long-life performance and good edge strength — meaning your cost-per-part drops.
-
Versatility: One insert covering multiple operations (turn-milling/drilling) means fewer SKUs, easier inventory and faster changeovers.

Frequently Asked Questions
It’s optimized for non-ferrous metals (aluminium, copper alloys) and heat-resistant alloys, but its general-purpose H01 grade also handles many general engineering steels and alloys reliably.
Yes, the negative SNEX geometry and MA chipbreaker make it suitable for milling (especially square-insert milling) and it can also serve in turning operations where the holder and machine setup allow.
The H01 grade offers an excellent balance of edge strength and versatility; for certain materials and high-speed non-ferrous jobs the uncoated polished finish gives optimum chip flow and avoids built-up-edge issues — leading to longer life.
The MA chipbreaker design helps manage chip evacuation more efficiently, lowers cutting loads, improves surface finish and helps maintain stable performance — which reduces tool change-outs and maximises uptime.
Confirm the insert size (1206 in this case), the correct holder compatibility (SNEX series may require specialised clamps/holders), stock availability at CNC Tools Depot, lead times and whether your machining application aligns (feed/speed, material, coolant) for best performance.
