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.


Product Details--- MTHR A55 Inner Threading Tool

  • Tool Material: 100% virgin tungsten carbide.
  • Usage: Designed for internal threading machining; also functions as an inner hole dental cutter.
  • Hardness: HRA 91–93.5
  • Accuracy: ±0.005 mm
  • Coating: To be defined based on your application. The smooth, fine surface of the coated carbide provides an excellent surface finish.

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.
