H7 6 Flutes High Speed Steel Reamers Carbide Reamer For Steel

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.

• 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.

• 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.

• 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).
