Importance of contact point of drawing die

The recommended contact point on the reduction zone of a die should be 75% to 100% of the wire diameter. The bearing (or land) of a die is downstream of the drawing cone, and although it plays no part in the prior reduction in area of the wire, it does help to preserve the wire size. A bearing surface that is too large will increase the drawing stress because of friction.
