Insert for metric external threads 16 EL 3.5 ISO BMA - pitch precision 3.5 mm
Insertfor metric external thread s 16 EL 3,5 ISO BMA is a professional tool with full profile dedicated to turning left-hand threads with pitch P=3,5 mm. The designation EL (External Left) indicates external left application, but the insert is interchangeable and can work as internal right (IR) after using a suitable turning knife, which significantly increases its versatility in the workshop.
Key advantages of the 16 EL 3.5 mm ISO BMA insert
- Full 3.5 mm pitch profile - guarantees the highest quality and precision for M30 and M33 threads
- EL/IR interchangeable insert - works as external left and internal right for metric threads
- 60 degree ISO angle - conforms to the standard for metric threads
- BMA grade - universal for steel, cast steel, cast iron and non-ferrous metals
- Size 16 mm - compact tool with high clamping stability
The 16 EL 3.5 ISO BMA insert is the choice of professionals making threads on the lathe with requirements for the highest precision. The full profile ensures perfect reproduction of the thread outline, which is crucial in the production of responsible parts. Bet on a tool proven in demanding applications - order a 3.5 mm external thread insert that combines functionality with excellent workmanship.

Frequently asked questions
1. What is the difference between full profile and incomplete profile?
The full profile is dedicated to a specific pitch of 3.5 mm, which guarantees the best thread quality and perfect reproduction of the ISO standard. The incomplete profile (e.g., N60) supports the pitch range, but offers slightly lower precision. The full profile is the choice for applications requiring maximum accuracy and repeatability of threading on the lathe.
2. Can the 16 EL insert be used for internal threading?
Yes, despite the EL (External Left) designation, this insert is interchangeable and can be used as an internal right (IR) for metric threading when the appropriate toolholder is used. It requires a 16 mm lathe cutter. The BMA grade provides versatility for machining a variety of materials, from steel to non-ferrous metals.
3. What is the height of the turned thread outline for this insert?
H1 - Height of the thread outline given in mm || P - pitch of the thread given in mm
H1 = 0.54127 * P
For this pitch is: H1 = 0.54127 * 3.5 mm = 1.89 mm
