Precision Micro Boring Head Set with BT40 Shank for Industrial Milling

High-grade hardened steel construction ensures exceptional durability and wear resistance for long-term precision machining. The adjustable boring bar accommodates 6-51mm diameter ranges with micron-level accuracy, ideal for aerospace, automotive, and mold-making applications.

BT40 taper shank guarantees secure mounting on CNC milling machines, reducing vibration for superior surface finishes. Includes multiple interchangeable cutter heads for versatile operations like fine boring, chamfering, and step machining.

Heat-treated alloy components resist deformation under high-speed operations (up to 4000 RPM). Ground gears provide smooth feed adjustments (0.01mm increments) for ultra-fine tolerance work. Perfect for jig boring, engine block machining, and precision toolroom tasks.

Complete kit features anti-rust coated storage case. Backed by industrial-grade warranty. Bulk order discounts available for machine shops and OEM manufacturers.
