Application Field:

The MTHR A55 is an internal boring and turning tool featuring 55° angled tips, widely used for finishing inner hole threading in mini turning lathes. Unlike the round shank MIR A55, the MTHR A55 has a rear end tilt, making it suitable for locking into precise tool holders. Additionally, its advanced nano coating on ultrafine carbide ensures a high-quality, smooth machining surface and excellent wear resistance. This tool is ideal for a wide range of materials, particularly stainless steels and various alloys.

Summary product information as below:

Product Features:

• No Need for Recalibration: Eliminates time costs and enhances efficiency.

• Integrated Design: The boring tool is integrally formed, and its unique chip flute design reduces chip buildup, significantly improving processing efficiency.

• Precision Grinding: The entire process utilizes a five-axis machine tool for precision grinding, ensuring high accuracy of the tool tip's r-angle and a smooth cutting edge under 500x magnification.

• Internal Cooling: The slotted design on the inclined section at the tail, along with a central water outlet in the cutter sleeve, enables effective internal cooling during processing.

• Stable Positioning: Solid carbide boring bars are precisely positioned in the adaptor using a locating pin, while set screw clamps ensure increased stability for rigid clamping.

• Easy Tool Changes: Tools of the same type can be changed using the positioning pin, maintaining the same total extension length.
