Mingzhe Tungsten Steel Boring Tool 4mm Diameter 0.05in Precision 2-flute for Automatic Lathe Small Inner Hole Processing

This solid carbide boring tool adopts premium KT40 substrate, delivering outstanding hardness and wear‑resistance. It works stably for steel and stainless steel small inner‑hole machining. The fine‑tuned coating reduces cutting heat and friction, effectively resisting chipping and abrasion during continuous cutting. It maintains sharp cutting edges for long‑time production, lowering frequent tool replacement costs for automatic lathe processing.

MQR series micro boring tool is specially designed for tiny inner‑hole turning on automatic lathes. It realizes precise small‑aperture boring with stable chip removal performance. Its compact structure adapts well to narrow internal cavity scenarios. It suppresses tool vibration during fine boring, securing consistent dimensional accuracy and smooth inner‑wall surface finish for mass‑production machining tasks.

Optimized geometric cutting edge greatly lessens cutting resistance for smooth, light‑load cutting. It fits perfectly with automatic lathe equipment, helping raise overall processing efficiency. Reliable repeatability minimizes dimensional deviation in batch parts. This boring cutter helps workshops cut down defective rates, bringing stable, cost‑effective performance for daily small‑hole turning manufacturing.
