SBXR Tungsten Steel MXR Mini Lathe Boring Cutter Shockproof Internal Turning Tool with Small Hole Diameter
This MXR and SBXR series micro internal tool is built from solid tungsten carbide with optimized anti-vibration structure. It comes in right-hand MXR and left-hand MXL versions for back-pull machining of bores above 4mm, ideal for precision micro turning on Swiss-type CNC lathes.
Precision-ground cutting edges with R0.2 nose radius ensure steady performance in back boring and grooving operations. The wear-resistant hard coating guarantees smooth chip evacuation, suppresses chatter, and delivers consistent dimensional accuracy and fine surface finish for steel and stainless steel.
It offers a full range of specifications including standard MXR and premium SBXR models with multiple shank sizes. Its compact rigid body fits narrow inner-hole spaces, prolongs tool life, reduces changeover downtime and boosts mass-production efficiency of miniature components.
