Learn more about Klarna
Description
The Carmex Spiral Point UNC Supercut Tap (No. 8 x 32) is a high-performance threading tool built for professionals who need precise UNC threading in demanding materials.
- Threading type: Spiral Point design that efficiently pushes chips ahead, enabling smooth through-hole threading and reducing the risk of chatter or clogging.
- Material: HSS‑E (high-speed steel with cobalt) for exceptional hardness, wear resistance, and heat tolerance during fast, heavy-duty threading.
- Size & pitch: No. 8 diameter with 32 TPI (UNC), ideal for small-diameter fastener holes and standard coarse-thread applications.
- Cutting geometry: Supercut profile with optimized edge geometry to deliver clean, accurate thread form at higher production speeds.
- Chip control: Spiral point channels debris away from the flutes, promoting consistent cuts and reducing downtime for clearing chips.
- Applications: Designed for challenging materials and high-speed threading operations, providing reliable performance in production and workshop settings.
With its robust HSS‑E construction and purpose-built spiral geometry, this tap delivers durable performance, precise thread quality, and dependable results—making it a trusted choice for engineers, machinists, and assembly specialists tackling UNC threads in tough materials.
