The new drill thread mill, a 4-fluted helical drill thread milling cutter for high-strength and hardened steels up to 66 HRc, combines core hole and thread production in one tool. Also, one cutter for 2 different operations saves time on tool changes and leaves more room in the tool carousel. This makes the tool especially well-suited for mass-production applications, or applications where frequent tool changes are undesired. The TMD-NX from STOCK guarantees process reliability and true gauge threads.We recommend using high quality shrink fit holders or suitable side-lock chucks to guarantee the highest stability, concentricity and drilling+milling efficiency.
Features:
- oil grooves on the shank
- special face geometry with hollow grinding
- left cutting geometry
- made of special fine-grained carbide
- very hard and temperature-resistant TiSiN coating
Advantages:
- excellent machining results in both dry (air) and wet machining
- universally applicable in almost every material up to 66HRc
- high process reliability and true gauge threads
- significantly shorter cycle and setting time
- suitable for both blind and through holes
- thread depth can be up to 2.5xD
- one cutter for 2 different operations
- considerable process cost saving potential
