Solid Carbide Straight Flute Reamer Customized 6 Flute Reamer H7

Solid Carbide Straight 6 Flutes Reamer CNC Machining Centers

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:

6-Flute Straight Design

• Superior hole roundness & finish vs. 4-flute reamers.

• Zero helix angle prevents material pull-out in brittle metals (cast iron, ceramics).

Premium Coatings for Extreme Wear Resistance

• TiAlN (Titanium Aluminum Nitride) – Best for hardened steels (HRC 45+) & high-temp alloys.

• AlCrN (Aluminum Chromium Nitride) – Superior for stainless steel & Inconel.

• DLC (Diamond-Like Carbon) – Low-friction for sticky materials (aluminum, copper).

Solid Micro-Grain Carbide Construction

• 5× longer tool life vs. HSS reamers.

• Stable in high-speed CNC machining (up to 30,000 RPM).

Coolant Compatibility (Through-Spindle or External)

• Prevents heat buildup in deep holes (up to 10×D).

• Flushes chips to avoid scoring finished surfaces.

Precision Ground to Micron-Level Tolerances

• Diameter tolerance: H6/H7 (custom grades available).

• Runout < 0.005mm for perfect concentricity.

Typical Applications:

✔ Precision Boring (Hydraulic valves, bearing housings)
✔ Aerospace Components (Turbine blade cooling holes, bushings)
✔ Medical Devices (Implant screw holes, surgical tool guides)
✔ Automotive (Fuel injector nozzles, transmission bores)
✔ Mold & Die (Ejector pin holes, core alignment bores)
