Turning insert for industrial threads 22 ER series pitch 3.5 to 5.0 mm
The 22 ER N60 HTA thread turning insert is a professional tool for turning external threads with coarse pitches of 3.5 to 5 mm on large-size parts. The insert for right-handed metric external threads in the reinforced 22 series guarantees process stability at the high cutting forces encountered when machining large diameters in the machine tool industry.
Key benefits of the 22 ER N60 HTA insert
- Series 22 for maximum rigidity - reinforced design larger than Series 16 eliminates vibration when threading large shafts on the lathe
- Full range of large size threads - supports M30, M36, M42, M48 and larger with 3.5-5 mm pitch in industrial designs
- Universal N 60-degree profile - compatibility with metric coarse threads and US UNC large size threads with appropriate pitch
- Mounting versatility - use in external right-hand and internal left-hand 22 series toolholders after changing the turning knife
- Extended durability - solid construction provides wear resistance for heavy-duty machining of large diameter steel parts
This tool is appreciated in heavy machinery and steel structure manufacturing plants making large threads on the lathe. It works well in repair shops serving the mining, construction and machinery industries requiring coarse pitch threads. Remember to carefully prepare the outside diameter of the shaft before the threading operation.

Frequently asked questions
1. Which lathe knives does the 22 ER N60 HTA insert fit?
The 22 ER N60 insert is installed in 22 ER series right-hand external socket turning k nives and 22 IR series left-hand internal boring tools. Thanks to the versatility of the design, the same insert works with different types of lathe holders after changing the cutter, which allows you to make external and internal threads.
2. What kind of large threads will you make with the 22 ER N60 insert?
The insert allows you to turn M30, M36, M42, M48 and larger metric coarse thread s with pitches of 3.5-5 mm. In addition, it supports large-size American UNC thread s with an outline angle of 60 degrees used in heavy industry, mining machinery and steel structures that require robust threaded connections.
3. What are the characteristics of the N 60 profile in a threaded insert?
Profile N 60 is a partial profile with an outline angle of 60 degrees that forms only the lateral surfaces of the thread without finishing the apexes. Before starting threading, it is necessary to prepare the exact nominal diameter of the shaft with a turning operation, since the insert does not include finishing of the cylindrical surface beyond the thread outline itself.
4. How to calculate the depth of the thread for a pitch of 3.5-5 mm?
H1 - Height of the thread outline given in [mm] || P - pitch of the thread given in [mm]
H1 [mm] = 0.6134 × P
