Made of high speed steel material, and long service life
In the milling machine, if you need to change the diameter of the normal machining diameter, you can adjust the shaft position of the eccentric sleeve. If you want to increase the hole diameter, rotate the sleeve clockwise, to reduce the aperture, rotate the sleeve counterclockwise
The eccentric sleeve can overlap the shaft direction of the drill bit with the shaft direction of the spindle within the range of 0.2mm (rotate the eccentric sleeve counterclockwise to expand the hole diameter adjustment)
The tool diameter is adjustable, mainly used in U drills, quick drill and water jet drills
The diameter is adjustable, adjust diameter from -0.2 to +0.4
