Production information

Good heat dissipation and chip removal along with the use of cooling lubricants are vital. When drilling holes with large diameters, the cross-cuts that are otherwise usual should be decreased, and the drill diameter should be produced in stages.

Band saws, circular saws, and hack saws with a large tooth pitch and slight tooth setting are suitable.

As of a semi-finished product diameter of 80 mm, the material should be preheated to 80°C in order to prevent the formation of block cracking in the semi-finished product.
