Uncoated Solid Carbide Reamer H7 Reamer Cutting Tool Customized With Coolant Hole

Solid Carbide Straight 6 Flutes Reamer CNC Machining With Coolant Hole

Introduction:

The AMG Solid Carbide 6-Flute Reamer with Coolant Hole is a high-precision finishing tool designed for ultra-smooth, tight-tolerance hole machining in metals, plastics, and composites. Its straight flute design and internal coolant channels ensure superior surface finishes (Ra ≤ 0.4μm) and extended tool life in demanding CNC applications.

Features:

6-Flute Design for Precision Finishing

• More cutting edges = finer finish & better roundness (IT6-IT7 tolerance achievable).

• Balanced cutting forces reduce vibration for burr-free holes.

Through-Tool Coolant Holes

• Directs coolant to cutting edges – prevents heat buildup in deep-hole reaming (5×D+).

• Improves chip evacuation – critical for stainless steel, aluminum, and tough alloys.

Solid Micro-Grain Tungsten Carbide

• 3-5× longer life vs. HSS reamers.

• Stable in high-speed machining (HSM) up to 30,000 RPM (varies by diameter).

Straight Flute Geometry

• Zero helix angle prevents "threading effect" for truer hole geometry.

• Ideal for brittle materials (cast iron, ceramics) where helical flutes may chip edges.

Coating Options (Optional)

• TiN (Gold) – General-purpose for steel/plastics.

• TiAlN (Purple-Black) – For high-temp alloys (Inconel, titanium).

• DLC (Diamond-Like Carbon) – Non-stick for aluminum/copper.

Typical Applications:

✔ Hydraulic/Pneumatic Components (Valve bodies, cylinders)
✔ Aerospace (Bushings, landing gear bores)
✔ Medical Implants (Bone screw holes, surgical tools)
✔ Automotive (Fuel injectors, transmission bores)
✔ Mold Making (Ejector pin holes, guide bushings)
