RUKO KEB-HSS-TiAlN-Mod.55-42.0mm Reamer

The KEB-HSS-TiAlN-Mod.55-42.0mm reamer stands out with its titanium aluminum nitride (TiAlN) coating, which significantly boosts wear and heat resistance compared to uncoated HSS reamers. This coating allows for higher cutting speeds and extends tool life, making it a cost-effective choice for high-precision reaming operations.

Highlights

• Nominal diameter: 42.0 mm
• High-speed steel (HSS) body with TiAlN coating
• Right-hand cutting direction
• Multi-flute design for smooth cutting and excellent surface finish
• Cylindrical shank with drive flat for secure clamping
• Optimized for external coolant application
• Suitable for steel, stainless steel, cast iron, and non-ferrous metals

In daily use

This reamer delivers high-precision holes with a surface quality comparable to H7 tolerance class. Its optimized cutting edge geometry and efficient chip evacuation ensure reliable performance in both CNC and conventional machining environments. The TiAlN coating reduces friction and heat buildup, allowing for longer uninterrupted runs and consistent hole quality.
