V is another code for diamond shape (35 degree)

K Shape is a parallelogram in shape (55 degree)ħ. D Shape is also a Diamond shape (55 degree)ģ. C shape is the diamond shape (80 degree)Ģ.

You should have detailed knowledge about all these shapes before you are going to buy.ġ.

There are different shapes of inserts available in the market. As pcd is a polycrystalline form of diamond, so the cutting temperature is limited and could not exceed 700℃, also the work material has no affinity with carbon, pcd inserts are widely used for machining non ferrous metals of tungsten carbide, aluminum, copper, zinc and non metals material of plastic, rubber, wood, ceramics.

Polycrystalline diamond inserts with brazed pcd cutting edgesĪdvantage of tipped pcd inserts over full faced pcd inserts is the lower cost, tipped insert is one use only economical type, it requires a carrier like tungsten carbide base as substrate for the insert, and substrate have a pocket that will accommodate and support the tip, the working tips are brazed to tungsten carbide base, 1~4 tips depends on different insert shapes, this braze joint of tipped pcd inserts represents the weak link not so good as full face pcd inserts, the maximum cutting depth is not more than 80% of the tip length, tipped pcd inserts could be used for fine to super fine precision machining, continous to interrupted machining, to obtain a good surface finish.
