IC328 cemented carbide insert – design and applications
rectangular 85° with a large corner radius for profile milling
The ADKT 150520 milling insert is an indexable cemented carbide insert in coated grade IC328, designed for indexable milling cutters and milling heads operating at a right angle. Shape A, a parallelogram with a 85° corner angle, combined with a large 2.0 mm corner radius, makes the insert suitable for high-performance profile and contour milling. The positive 15° clearance angle reduces cutting resistance and enables smoother milling head operation, even on machines with moderate power. The countersunk hole and single-sided chip breaker (type T according to ISO 1832) control chip evacuation when machining with one side of the insert. Coated grade IC328 covers ISO P and M groups, so one insert handles both steel and stainless steel.
Key benefits of the ADKT 150520 cemented carbide insert
- Two cutting edges — the 85° rectangle provides 2 working corners; once worn, rotate the insert in its pocket without replacing the entire milling head.
- Coated grade IC328 — carbide for steel (ISO P) and stainless steel (ISO M).
- Positive 15° geometry — lower forces and power consumption, smoother milling head operation on slender and thin-walled workpieces.
- The large 2.0 mm corner radius supports profile and contour milling and a smooth profile floor.
- The 5.5 mm body thickness increases edge strength at greater depths of cut.
- The countersunk hole allows the insert to be seated in its designated tool pocket.
Applications and cutting data selection for the ADKT insert
The ADKT 150520 indexable insert performs well in shoulder, pocket, and profile milling in structural steel, alloy steel, and stainless steel. Calculate spindle speed using n = 1000·vc/(π·D): for a milling head with a diameter of 63 mm at a cutting speed of vc = 160 m/min, the result is approximately 808 rpm. With five inserts in the milling head and a feed per tooth of fz = 0.15 mm, this gives a table feed rate of approximately 606 mm/min. The abbreviation fz denotes the feed per cutting edge during one revolution of the milling head.
The large corner radius distributes the load over a longer section of the edge and improves the finish of the profile floor, but increases radial forces. For this reason, mount the milling head rigidly and select a depth of cut that does not exceed the active cutting edge length. For stainless steel, maintain a constant feed and continuous cooling, as some stainless steels dissipate heat poorly and work-harden when cutting is too slow. Climb milling on a CNC machine with table backlash eliminated extends edge life and reduces vibration.

Application limitation
Coated grade IC328 is intended for groups ISO P and ISO M. For other material groups, select a grade approved by the tool manufacturer. The large corner radius 2.0 mm increases radial forces and requires rigid mounting of the milling head.

Frequently asked questions about the ADKT 150520 insert
number of edges, materials, differences, and dimensions
Two — the 85° rectangle provides 2 corners for cutting, and the positive geometry with a clearance angle of 15° makes the insert single-sided, cutting only with its top face. Once a corner is worn, rotate the insert in its pocket to the next edge without replacing the milling head.
Coated grade IC328 covers steel in group ISO P and stainless steel in group ISO M. For steel, maintain a cutting speed of 130–200 m/min, for stainless steel 70–130 m/min with a constant feed and continuous cooling.
Both shapes are rectangular 85° for milling heads operating at a right angle, and they differ in clearance angle: ADKT has an angle of 15° (letter D), while APKT an angle of 11° (letter P). The inserts must not be interchanged in the same milling head pocket.
The corner radius rε is 2.0 mm (code 20 in the ISO 1832 designation), the insert thickness s is 5.5 mm, and the side length l is — 15.00 mm. The large radius and thick body make the insert suitable for productive profile milling.
