คุณลักษณะ

• Since the groove is twisted, small curly continuous chips are discharged backward, and chip clogging does not occur, making it suitable for blind hole machining.
• Since it has good sharpness, it is especially suitable for screwing sticky work materials and plastics.
• Taps are easy to bite.
• Intermittent cutting of pilot holes with key grooves is also possible.
• Since the blade strength is inferior to HT, HT shape is more suitable for high hardness materials.
• For blind hole machining.
• Work Material: Medium Carbon Steel, High Carbon Steel.
