John,

Nope, EN1A is free cutting, although it may be possible to get 'square section' in EN1A.

Trouble is BMS can be anything you want it to be  :clap:

I've had BMS EN1A in round, square and flat form from the suppliers I use..

John,

Do you use Key steel? or have you used it?

John Rudd:
Yes on both questions...

In fact I have a piece of 1/2 in sq KS under my bench.. :lol:

DaveH:
John,

What are your impressions, do you think it cuts "better" - why is it manufactured?

Why not just use "bright mild steel"?,  I am just trying to figure out should I buy key steel or orinary "bright mild steel"

John Rudd:
I'm sure the composition of key steel is different to say EN1A, as it has greater shear resistance hence it being used for keys in keyways...Or have I totally misread this thread? :doh:
