Solid Carbide Straight 6 Flutes Milling Reamer for steel with coolant through hole

Introduction:

The AMG Solid Carbide 6-Flute Straight Reamer is a high-performance finishing tool designed for ultra-precise hole machining (IT6-IT7 tolerance) in CNC machining centers. Featuring advanced coatings and optimized flute geometry, it delivers mirror-like surface finishes (Ra ≤ 0.4μm) in hardened steels, aluminum, and exotic alloys.

Features:

Blind Hole-Specific Geometry

• Reduced Lead Angle (3°) – Minimizes bottom interference

• Precision Guide Pads – Maintain hole straightness at 5×D depth

• Controlled Edge Prep – Honed cutting edges prevent workpiece material smearing

Premium Material & Coatings

• Substrate: Ultra-fine grain carbide (10% cobalt)

• Standard Coating: AlCrN for steel/alloys (TiAlN optional)

• Special Option: DLC coating for aluminum/copper alloys

Enhanced Process Reliability

• Runout < 0.003mm – Ensures consistent hole size

• Balanced Flute Spacing – Eliminates harmonic vibration

• Wear Indicators – Visual inspection grooves for tool life monitoring

Typical Applications:

• Hydraulic/pneumatic components (valve bores, cylinders).

• Automotive (fuel injectors, transmission gears).

• Mold/die (ejector pin holes, core guides).
