OSG Threading Tap - Metric Forming Tap (Roll) HSS-E - TIN Coated - Fluteless - M3 x 0.5
Learn more about Klarna
Description
The OSG Metric Forming Tap (Roll) M3 x 0.5 is a precision tool designed to form threads by material deformation, delivering strong, chip-free results in ductile metals. Built for serious machining tasks, it combines reliability with long tool life for production environments that demand consistency.
- Size: M3 x 0.5
- Type: Metric forming tap (roll-forming), fluteless
- Material: HSS-E (high-speed steel with cobalt) for toughness and wear resistance
- Coating: Titanium Nitride (TIN) coating to reduce wear and friction
- Design: Fluteless geometry that forms threads through deformation, producing chip-free operation
By forming threads rather than cutting them, this tap yields stronger, more uniform threads with better surface finish and fatigue resistance. The TiN coating extends tool life by reducing wear and heat buildup, while the fluteless design minimizes chip generation and chatter, enabling smoother operation and potentially higher tapping speeds in suitable materials.
