H7 6 Flutes High Speed Steel Reamers Carbide Reamer For Steel

Carbide 6 flutes reamer H7 with X-pro Si coating for steel through coolant reamer

Introduction:

This high-precision carbide reamer is designed for ultra-fine hole finishing in steel and alloy materials, offering superior accuracy, extended tool life, and efficient chip evacuation with through-coolant capability.

Features:

1. Precision & Performance

• H7 Tolerance (≤ 0.0008") – Ensures tight, consistent hole sizing for high-accuracy applications.

• 6 Flutes Design – Balances cutting speed and surface finish, reducing vibration for smoother holes.

• Through-Coolant (Internal Coolant Channels) – Improves chip evacuation, reduces heat buildup, and extends tool life.

• Carbide Substrate – High rigidity and wear resistance for long-lasting performance in hardened steels.

2. Advanced X-Pro Si Coating

• Enhanced Lubricity & Heat Resistance – Reduces friction and prevents built-up edge (BUE).

• Oxidation Resistance – Withstands high temperatures in aggressive machining.

• Extended Tool Life – Up to 3x longer than uncoated or standard TiN-coated reamers.

Typical Applications:

• Precision hole finishing in steels (carbon steel, alloy steel, tool steel).

• High-production machining (automotive, aerospace, mold & die).

• Deep-hole reaming (coolant flushes chips effectively).

• Stainless steels & difficult-to-machine alloys (with optimized parameters).
