Small Diameter Tungsten Steel Single-Head Profiling Turning Tool Mqr 6R0.2 L22 47° Angle Internal Boring Tool
This MQR 6R0.2 L22 single-head internal profiling tool uses solid tungsten carbide with HRC92.6 substrate hardness. Its 47° main angle and 6° relief angle design supports both right-hand and left-hand versions, ideal for precision profiling of bores above 2mm on Swiss-type CNC lathes.
The precision-ground R0.2 cutting tip ensures smooth chip evacuation in narrow inner-hole spaces. The wear-resistant hard coating effectively suppresses built-up edge, delivering excellent surface finish and stable dimensional accuracy for steel and stainless steel workpieces.
Its slim rigid shank perfectly fits the limited working space of small-bore machining. It extends tool service life, reduces tool-change downtime, and significantly improves overall productivity for mass production of miniature precision mechanical parts.
