1.Four Corner Design Maximes Productivity and Cost Efficiency
The new four corner design has an insert shape that is almost identical to the conventional IASR two corner design. This new shape has the rigidity and productivity of the previous insert and the four usable corners creates greater cost-efficiency.
2.Direct Milling
Since the cutting flutes do not extend to the center, there are limitations on the ramp angle and hole diameter. As shown below, processing by direct milling without a pilot hole is possible for both ramping and helical milling.

[Note]
- The ramp angle θ should be set within the ranges listed above. Use at ramp angles of 1 or less is recommended.
- For hole diameters outside the ranges listed above, a pilot hole should be drilled before milling.
3.Programming Information
For rough milling, please create a program with corner radius values close to the reference values shown below.
