Description
OSG Metric A-Spiral Flute Threading Tap is a left-hand, TiCN-coated tool designed for precision blind-hole threading in metalworking. Built on a durable powder-metal substrate, it delivers reliable cutting performance in restricted cavities where reverse-threaded features are required.
- Thread size & standard: Metric M14 x 2 with DIN 376 specification, left-hand thread configuration for reverse-threaded applications.
- Flute geometry: A‑Spiral flute design engineered to efficiently evacuate chips in blind holes, reducing clogging and improving thread quality.
- Material: Powder metal substrate chosen for strength-to-weight balance and long tool life in demanding environments.
- Coating: TiCN multilayer coating to enhance wear resistance and heat tolerance during cutting.
- Application: Specifically suited for blind-hole threading across a range of metallic workpieces, supporting cleaner starts and deeper, consistent threads.
- DIN standard: Conforms to DIN 376 for reliable interoperability with metric threading components.
This tap delivers practical improvements in production settings: it supports cleaner threads in blind holes, longer tool life through wear-resistant coatings, and stable cutting action thanks to the powder-metal core. The combination of left-hand threading, TiCN coating, and A‑spiral geometry helps machinists achieve accurate thread depth with fewer reworks and less downtime, making it a dependable choice for precision assemblies.
