DHR237 Tough-Pitch Copper Comparison of cutting surface
Material: Tough-Pitch Copper
Work size: 8x15 mm
Cutting depth: 12 mm
Tool
DHR237
●Long neck end mill specialized for machining copper alloy.
●Helix angle 【37.5°】 degrees to achieve both sharpness and finished surface quality that prevents scratches on cutting surface.
●High quality and stable milling performance with long tool life by optimized design and DLC coating.
●Machining copper tungsten electrodes is also effective.

Comment
Comparison of cutting surface
After 10 hours machining, DHR237 still can achieve high quality cutting surface.
In the rival products, the processing surface roughness could not be kept constant.
Comparison of tool wear
Because of the 37.5°helix angle, burrs, wave and cutting resistance have been effectively decreased!
DHR237 has 2 times tool life comparing to the rival products.
Upper burr amount
DHR237 suppressed the occurrence of burrs and achieved the sharp edges.
