Specification

For blind holes and through holes, for higher-resistance receiving threads

The W-Tec® Insert Coil thread mould forms the receiving thread rather than cutting it. The material's fibre structure is pushed outwards rather than being severed as in the chipping method.

Your benefits

Moulded thread with higher load capacity

Improved surface quality

No chipping problems

Higher cutting speeds than thread cutting

Longer service life than screw taps

Application areaSuitable for the following materials:

Stainless steels up to 950 N/mm²

Construction steels up to 800 N/mm²

Reference values for determining cutting speed for W.Tec® insert coil thread former
Material	Strength	Cutting speed in m/min	Recommended lubrication
Structural steels, carbon steels, cold extrusion steels etc.	< 600 N/mm²	20 - 80	Cutting oil/emulsion
Structural steels, case-hardening steels, cast steel etc.	< 800 N/mm²	20 - 60	Cutting oil/emulsion
Heat-treated steels, cold working steels, nitriding steels etc.	< 1000 N/mm²	10 -40	Cutting oil
Stainless steel (austenitic, ferritic, martensitic)	< 950 N/mm²	10 -25	Cutting oil
Aluminium wrought alloys	< 550 N/mm²	15 - 40	Cutting oil/emulsion
Aluminium cast alloys	Si < 12 %	15 - 40	Cutting oil/emulsion
Pure copper	< 400 N/mm²	20 - 40	Cutting oil/emulsion
Brass (copper-zinc alloy)	< 550 N/mm²	40 - 80	Emulsion
Cutting speed [m/min] = (external diameter x π x speed)/1000 Speed n [rpm] = (cutting speed in m/min x 1000)/(external diameter x π) Feed [mm/min] = speed x thread pitch The cutting speeds indicated above are to be understood as reference values and may vary depending on the machining conditions and must be adjusted accordingly.
