- Description
Mold and die industry often have to tapping hardened materials, that require specific taps to handle high hardness steels.
OPT carbide machine tap and carbide hand tap set are designed for tapping hardened steel and extremely high hardness steel up to 63 HRC.
ISO standard, JIS standard, DIN standard carbide tap all avaialble and can be customized with short lead time.
Usually to be used on CNC machining, tap set also available for manuel use.
- Typical application
Tool materail: Considering wear resistance and impact resistance, ultra-fine tungsten carbide materials with reasonable hardness and toughness are used to ensure the durability of carbide taps
Geometry: To increase rigidity and prevent edge breakage, special rake angles are designed
Chamfer length: Considering stability and toollife, the length of the cut in chamfer is usually 4-5 teeth
Machine: Suggest to use a machine tool with low vibration and the ability to choose a reasonable feed rate to achieve stable tapping
Bottom hole: Drill the bottom hole as large as possible within thread tolerance because it helps reduce the torque load and tapping becomes longer life.
