• Angle Milling Cutters
• Shank Diameter ：3.175/4/5/6/6.35/8/10mm
• The design of up and down cutting spiral router bit effectively reduces cutting resistance facilitates chip removal makes the workpiece smoother and brighter and further improves processing efficiency.
• The 2-flute carbide router bit is widely used for plastic boards MDF density boards plywood hardwoods particle boards and so on.
• The compression cutter is designed with top and bottom grooves to prevent delamination of the top and bottom of the workpiece.
• The end mill cutting edge is hard and sharp which can process heat-treated materials at high speed reduce the number of tool changes and increase productivity.
