We are launching a new corporate website from this weekend (31 Jan – 1 Feb).
Incorrect axial feed rate in tapping can cause oversizing. Reduce rate by 5-10% or increase compression of tap holder to avoid this happening.
Avoid tool breakage caused by too high stock removal by decreasing feed per tooth.
Dormer has launched a new solid carbide drill for applications up to 8xD.
Dormer has launched a new Toolbox app for use on smartphones and tablets.
If suffering with a bad fit between shank and socket, ensure both are clean and free from damage to avoid broken and twisted tangs.
Increasing the number of flutes makes the load on each tooth more homogeneous and, consequently, this allows for a better surface finish. When using milling cutters with a high helix angle ensure the tool holder is good quality and has sufficient clamping forces.
Dormer has strengthened its solid carbide milling programme with the addition of 44 new products.
These include additions to existing families as well as several completely new ranges and provides a comprehensive offer covering almost every material type and application.
Taps with straight flutes: Straight flutes are the most commonly used type of tap, suitable for use on most materials including short chipping steel and cast iron.
