Product Detailed Description

The SCPR6-30L-R0.2-D6 small boring tool is a specialized precision cutting tool engineered for high-accuracy boring of miniature holes. It is designed to meet strict tolerances in electronics, medical, and aerospace manufacturing.

SCPR6: Standard indexable insert type.

30L: 30mm effective cutting length for deep micro-holes.

R0.2: 0.2mm nose radius for smooth surface finishes.

D6: 6mm tool shank diameter for stable clamping.

Key Application Scenarios

📱

Electronics Manufacturing: Perfect for finishing micro-holes (3-8mm) in PCB substrates, semiconductor housings, and smartphone frames.

🏥

Medical Device Production: Ideal for precision holes in stainless steel or titanium instruments where roundness and smoothness are critical.

✈️

Aerospace Components: Suitable for machining small holes in lightweight alloy parts like sensor brackets and valve cores.

Core Advantages

Exceptional Precision: Delivers consistent surface finishes (Ra ≤0.6μm) and runout tolerance (≤0.0015mm).
Stable Deep-Hole Performance: Carbide shank minimizes deflection during deep micro-boring, reducing tool breakage by 40%.
Versatile Compatibility: Fits standard SCPR6 indexable inserts and CNC lathe tool holders.
Wear Resistance: TiAlN coating resists heat and friction, extending tool life by 30%.
Cost-Effective: Indexable design allows quick replacement of worn edges, cutting changeover time by 50%.
