The demands on manufacturing nowadays are becoming ever more eacting and complex. We analyse your screw thread production and offer solotions that optimise your costs and product quality.
- Bell form thread milling cutter with HSK 50 taper adapter for high speed cutting of external threads.
- Drilling, thread milling, counterboring and spot facing tool for M14 x 1.5 drain plug thread in oil sump.
- Thread milling and counterboring tool for machining cylinder heads.
- Combined 45° counterbore and thread milling cutter with additional hole chamfering feature. The shank of this tool has coolant channels to optimise the coolant flow for cutting threads in through and small diameter holes.
- Combined drilling and thread milling tool for Pg7 conduit thread with four heavy duty end teeth.
- Thread milling and counterboring tool for S 80 x 3 buttress thread oil filter connection.
- Thread milling cutter for trapezoidal thread Tr 30 x 6

Advantages of thread milling
with shank thread milling cutters
on CNC milling- and turning-machines
- dimensional accurancy can be controlled
- tool breakage does not result in immediate scrap
- less power needed than for tapping
- short machining times due to high cutting speeds
- excellent thread surface finish
- short chips, hence no chip problems
- right and left hand threads in blind or through holes can be produced with the same cutter
- small cutting forces, hence threads can be cut on thin walled workpieces
- cutting speeds and feeds can be matched indivitually to workpiece material
- no partially formed chips at the bottom of blind holes
- no change of direction of spindle rotation required
- no tapping chucks required, milling cutter chucks suffice
- exact thread depths
- no torn threads
- threads can be cut to near the bottom of blind holes
- simple machining of tough materials
