High speed steel |
||||
 |
Deburring tools are usually made from high speed steel (HSS). | |||
 |
It is called high speed steel because it is able to cut through materials faster than most other steel types. | |||
 |
High speed steel is made up of a variety of alloy steels.
The alloy mix for deburring tools is given the code M2. |
|||
 |
||||
What is the alloy mix for M2? |
||||
 |
The alloy M2 is made up of the following elements: | |||
 |
SteelSteel is an alloy of iron that is very strong, long lasting and shiny in appearance. Steel is made up of various elements. The type of steel produced depends on which elements are combined. |
|||
 |
Tungsten (W) also known as WolframTungsten is atomic no. 74. This element is a greyish white in colour and has the highest melting point of all the elements. It is a hard, rare metal with excellent corrosion resistance and robustness, but is often very brittle. In Spanish, the name Tungsten means ‘heavy stone’. |
|||
 |
Molybdenum (MO)Molybdenum is atomic no. 42. This element is silvery-white in colour, and has the sixth highest melting point of all the elements. It forms hard, stable alloys. |
|||
 |
This combination of alloy M2 is used for its high heat, abrasion and wear resistance and cutting under high pressure.
These properties make it a suitable material for making deburring tools. |
|||
 |
The downside to this particular type of HSS is its hardness, which can make the tool’s edges prone to chipping and breaking. | |||
Cobalt and tungsten |
||||
 |
Some deburring tools have cobalt or tungsten hardened tips. These are designed for deburring hardened metals (e.g. stainless steel and tool steel)
Cobalt is more heat-resistant and is good for machining stainless steel and cast iron, whereas tungsten can be used with any material. The disadvantage of both of these, however, is that they can become much more brittle and are more expensive. |
|||
Plastic |
||||
 |
The handles are usually made from hardened moulded plastic. This particular plastic is called polycarbonate. | |||
 |
Polycarbonate is used for electrical items because it has a high resistance to heat and is flame retardant.
Polycarbonate provides a strong, hard coating and can withstand everyday knocks, bangs, drops and wear and tear. |
|||
 |
Some handles have small rubber strips in place down the body, to provide the user with grip and comfort. | |||
