Brazed Carbide Machine Reamers - Model 900 - H7 Tolerance - For Machines

Machine reamers with cylindrical shanks of Utensileria Ossolana made of ultra-fine K10 micrograin and left-hand helical flutes at a 5° angle are precision tools primarily used for finishing operations in mechanical applications. These tools are particularly suited for reaming holes that require tight tolerances and high-quality surface finishes. The cutting material, classified as K10, is a tungsten carbide known for its extreme hardness and wear resistance, making it ideal for high-speed and precision machining. The ultra-fine micrograin structure ensures greater tool strength, durability, and excellent surface finishes.

The cylindrical shank allows for precise and stable mounting in machine tool holders, reducing vibrations during operation and improving accuracy and final quality. The left-hand helical flutes at a 5° angle facilitate optimal chip evacuation, minimizing the risk of clogging and enhancing surface quality. The 5° helix angle is designed to balance cutting edge strength and cutting efficiency, making these reamers suitable for materials such as steels, cast iron, and non-ferrous alloys.

These reamers are used in precision machining on CNC or conventional machines, where high-quality surface finishes and tight dimensional tolerances are required. They are widely employed in industries such as automotive, aerospace, and precision mechanical component manufacturing. Key advantages include high precision, ensured by the ultra-fine micrograin and tool geometry, long tool life due to K10 tungsten carbide, and excellent surface finishes thanks to the left-hand helix that reduces surface imperfections.

To maintain optimal performance, it is essential to use appropriate cooling fluids and regularly check for tool wear. These practices help extend tool life and ensure consistent results over time.
