General advantages of thread milling

Threads to different tolerance classes can be produced with same cutter
Tool breakage does not necessarily entail scrapping of the workpiece
Less power needed for cutting internal threads
Short machining times due to high cutting speeds
Excellent thread surface finish
Short chips, hence no chip problems
Right and left hand threads can be produced in blind or through holes by the same cutter
Low cutting forces enable threads to be cut in thin wall workpieces
Cutting speeds and feeds can be matched individually to workpiece material
No change of cutter spindle direction of rotation required
No special tapping chucks required, standard chucks suffice
Threads can be cut to exact depth
Threads can be cut down to near bottom of blind holes
Start of thread accurately determined by NC programme

Special advantages of type GFS thread milling cutter with chamfering capability

High productivity due to chamfering and thread milling with just one tool without tool changing
Reduction of both cutting time and non-cutting time in machining cycle
Saving of tool magazine places
Elimination of tool changing time
Reduction of setting time

Cutter can cut threads of identical pitch on a wide range of diameters
Low tooling costs for large threads
Neck between cutter teeth and shank allows appreciably deeper threads to be cut by a 2nd thread milling cycle

High productivity due to drilling, chamfering and thread milling with just
one tool without tool changing
Reduction of cutting and non-cutting times in machining cycle
Saving of two tool places
Fully cut thread only 1.3 x pitch shorter than depth of drilled hole
Both blind and through holes can be drilled and threaded
