It s been around a long time and enjoys a solid reputation among custom and factory knifemakers and knife users.
Cutting d2 tool steel.
D2 tool steel just keeps cutting.
However the aisi sae tool steel code categorizes tool steels based on basic application and material characteristics.
Thanks to robert erickson knifeandgear swiss dale bushness and paul hart for becoming knife steel nerds patreon supporters.
Turning speeds are adjusted to the feed rate of the mini lathe 0 004 rev a depth of cut of 0 040 and a tool life of 180 minutes.
It is also known by other names such as the japanese designation skd11 german designation 1 2379 hitachi sld uddeholm sverker 21 and many others.
Any input for a confused georgia boy.
D2 is a high carbon high chromium air hardening tool steel heat treatable to 60 62 rc.
Cutting d2 tool steel.
Tool steel refers to a variety of carbon steel and alloy steel that are particularly well suited to be made into tools their suitability comes from their distinctive hardness resistance to abrasion and deformation and their ability to hold a cutting edge at elevated temperatures.
D2 is widely used in long production cold work applications requiring very high wear resistance and high compression strength.
A favorite steel of such.
As a result tool steels are suited for use in the shaping of other materials.
It has high wear and abrasion resistant properties.
D2 offers excellent wear and abrasion resistance due to large volumes of carbides in the microstructure.
I have had suggestions that i anneal it and i hate doing that.
D2 steel is an air hardening high carbon high chromium tool steel.
D2 is a common tool steel and knife steel.
As with many high performance steels it experiences a range of highs and lows in popularity and at the moment seems to be enjoying a high.
This thread is old but man what terrible advice i machine d2 tool steel all day long everyday usually i use indexibles or high feed indexible end mills but when i run roughers i can take a 5 8 rougher 5 8 deep in an end mill holder at 12ipm and i believe 1528 rpm all day long that s unhardened d2 for hard d2 i wouldnt recommend a rougher at all standard 4 flute will work.
It is heat treatable and will offer a hardness in the range 55 62 hrc and is machinable in the annealed condition.
D2 steel shows little distortion on correct hardening.
