Description
Meet the OSG UNC A-Spiral Flute Threading Tap—a precision tool designed for tapping UNC threads in blind holes. Made from powder metal and TiCN coated, this right-hand tap delivers durable performance and consistently clean, accurate threads in tight spaces.
- Size: M2 x 56 steady diameter and length for small-diameter blind-hole applications
- Material: Powder metal construction for enhanced durability and wear resistance in demanding tapping tasks
- Coating: TiCN coating increases hardness, reduces friction, and extends tool life for high-speed, high-precision machining
- Flute Design: A-spirl (spiral) flute aids in efficient chip evacuation in blind holes and helps prevent tap binding
- Thread Type: UNC A (Unified National Coarse) threads for standard coarse-thread applications
- Handedness: Right-hand threading, compatible with common tapping setups
- DIN Standard: DIN2184-1 alignment to ensure consistent geometry and fit across compatible tooling
- Application: Specifically engineered for blind-hole tapping to promote smooth cutting and reliable thread formation
This tap is engineered to minimize chatter and wear while producing precise UNC threads in confined interiors. The combination of powder-metal core and TiCN coating supports longer use between sharpening, helping maintain productive cycles in professional machining environments. Its spiral flute design enhances chip flow, reducing the risk of clogging in blind-hole situations, and the DIN2184-1 specification helps ensure compatibility with standard tapping procedures and tooling setups. Ideal for small- to medium-scale production where reliable, repeatable threads are essential.
