Premium Thread Mill 'PRML'
Achieving beautiful skin with a threaded mill innovation
"PRML" is a premium thread mill specifically designed for machining fine-particle ultra-hard alloys. Because it cuts on the first thread, it is highly precise and minimizes taper on the finished threads. During cutting, it exerts less load on the tool, resulting in a long lifespan. Additionally, by rotating the tool counterclockwise, performing a one-pass finishing cut, and machining from top to bottom, it reduces cutting resistance. 【Features】 ■ Fine-particle ultra-hard alloy ■ Highly precise with minimal taper on the finished threads due to cutting on the first thread ■ Long lifespan with less load on the tool during cutting ■ Reduces cutting resistance by rotating the tool counterclockwise, performing a one-pass finishing cut, and machining from top to bottom *For more details, please refer to the PDF document or feel free to contact us.
