HSS Drill Bits Information

HSS drill bits (high speed steel drill bits) are the most numerous and versatile drill bits available. They were developed specifically for drilling into metal but they can also be used to good effect on lots of other common materials, including wood and plastic. There are quite a few designations of HSS drill bit; most of these refer to the manufacturing techniques used to make them.

Here's our Quick Application Guide:

• HSS-R Drill Bits - the "R" stands for Rolled. Rolled HSS drill bits are amongst the cheapest drill bits to manufacture and consequently they are usually cheap to buy too. They are not considered to be as high quality as HSS-G bits.
• HSS-G Drill Bits - HSS-G drill bits are fully ground, and can be made to finer tolerances than HSS-R bits. As a consequence they are usually more expensive to buy.
• HSS-TiN Drill Bits - TiN stands for Titanium Nitride, a coating that is applied with the intention of reducing friction on the bit, normally identifiable by a metallic yellow colouring.
• HSS-CO Drill Bits - CO stands for Cobalt, a coating that provides increased resistance to heat and wear, with the intention of prolonging the lifetime of the bit.
• HSS Jobber Drill Bits - "Jobber" is a standard of length, and bits made to this specification are ideal for general purpose applications in handheld drills and stationary machines.
