Titanium vs. Cobalt Drill Bits For Metal
                     Titanium vs. Cobalt Drill 
Bits For Metal
Cobalt drill bits and titanium coated bits are two of the 
most durable forms of drill bits. Both cobalt and titanium 
drill bits are very strong and powerful. By coming into 
contact with other metals, they are designed to prevent 
overheating, that is why it is so necessary to use an HSS 
drill bit for metal drilling.
MAIN DIFFERENCES TITANIUM DRILL 
BITS VS COBALT DRILL BITS
• Titanium Drill Bits
Titanium Drill Bits are made of 
steel and coated with titanium 
nitride or carbonitride
• Cobalt Drill Bits
Cobalt Drill Bits are made from 
a mixture of cobalt & steel 
alloys and are non-coated bits
APPLICATIONS OF COBALT AND 
TITANIUM DRILL BITS
They are designed to cut hard materials. While they're used 
more commonly for metal, and also work for hardwoods.
