Brazing
This is a process where molten brass is used to join two or more close-fitting parts (much like soldering).
The best process for making this joint is called vacuum brazing, this offers extremely clean, superior, flux-free braze joints of high integrity and strength.
All C.K Tungsten Carbide tipped drills are vacuum brazed – the opposite is an example of a non vacuum brazed tip and you can clearly see the difference in the joint quality.

Drill diameter by working length (X) by overall length (Y), for example 10x100x160mm.
