Frequently Asked Questions (FAQ)
Q1: What are the main features of the GT Tapper Handle?
A: The GT Tapper Handle features torque overload protection to prevent tap breakage. It also includes floating, telescopic, and quick-change functionalities for improved precision and efficiency.
Q2: Which machines are compatible with the GT Tapping Collets?
A: These tapping collets are designed for use with CNC machining centers, CNC milling machines, and other high-precision machine tools.
Q3: What materials and hardness levels are used in the GT Tapping Adapters?
A: Our tapping adapters are made from high-strength 20 CrMnTi steel, achieving a hardness rating of HRC48-50 and a precision accuracy level within ±0.003mm.
Q4: What are the tapping ranges for the GT12 and GT24 series?
A: The tapping range for the GT12 series is M3 to M16, and the GT24 series supports a tapping range from M3 to M30 (specifically M5 to M30 for the collets).
Q5: How does torque overload protection benefit the tapping process?
A: Torque overload protection automatically slips when the tapping resistance is too high. This prevents the tap from snapping inside the workpiece, saving tooling costs and preventing production downtime.
Q6: What packaging options are available for delivery?
A: We use professional, robust packaging solutions and reliable shipping methods to ensure your precision components arrive safely and in perfect working condition.
