ANVCD5USLTLong Shank Spiral Point Tap UNC 5USLTSold0pcsA South African-brand spiral point tap built from HSS-EX, the UNC 5USLT, ideal for tapping through holes — its spiral point pushes chips forward for fast, clean threading. Available in 19 sizes (thread dia 1~5, pitch 13~40, thread length 3mm, overall length 100~150mm, shank dia 3~9mm). A TiN coating adds a hard golden film for better wear and anti-galling, extending tool life. Suitable for machining carbon and alloy steel, stainless steel, cast iron, workpiece hardness up to HRC30. South African brand, consistent quality.

Product Overview: HSS Long Shank Spiral Point Tap Tiger UNC – 5USLT Series
【Product Features & Why We Recommend It】
- South African Brand Professional Quality: Originating from a professional South African cutting tool brand with rigorous quality control — recommended for users with standard demands on UNC long shank thread tapping stability and multi-material versatility.
- Tiger UNC Long Shank Deep-Cavity Solution: Features Tiger (TIGER) spiral point tap geometry combined with a long shank design — with overall length spanning 100–150mm, providing greater reach than standard shank models, recommended for UNC thread tapping in deep cavities, deep-cavity structures, or fixture interference situations where standard shank length cannot reach.
- HSS-EX Ultra-High Performance Substrate: Manufactured with HSS-EX ultra-high performance high-speed steel, delivering superior hardness, toughness, and wear resistance compared to standard HSS and HSS-CO — recommended for long-duration stable long shank UNC tapping of carbon steel, stainless steel, and cast iron.
- TiN Coating Enhancement: The surface is treated with TiN coating, providing good wear resistance and heat resistance — recommended for continuous UNC long shank tapping of carbon steel, alloy steel, stainless steel, and cast iron, effectively extending tool change intervals.
- Spiral Point Through-Hole Design: Features a spiral point tap design that pushes chips forward and out of the hole — recommended for multi-material UNC long shank through-hole tapping operations, ensuring smooth chip evacuation in deep cavities and thread accuracy.
- 19 UNC Specification Precise Coverage: Available in thread diameter 1–5 inches and pitch 13–40 TPI across 19 specifications — recommended as the dedicated long shank stock tool for deep-cavity UNC through-hole tapping, covering common North American specification deep-cavity workpiece tapping requirements.
【Machining Applications & Uses】
- Primary Use: UNC deep-cavity through-hole thread tapping, extended-reach deep-cavity structure UNC thread forming, and NC machining center long shank UNC automatic tapping.
- Recommended Work Materials:
- P-Class (Carbon Steel / Alloy Steel): Structural steel, carbon steel, and alloy steel — recommended for hardness below HRC30, where HSS-EX combined with TiN coating delivers stable long shank deep-cavity UNC tapping performance.
- M-Class (Stainless Steel): SUS304, SUS316, and other high-toughness stainless steel — the Tiger geometry combined with HSS-EX substrate effectively addresses work hardening and continuous chip formation challenges during deep-cavity machining, recommended for use with appropriate cutting fluid.
- K-Class (Cast Iron): Cast iron and gray iron — the TiN coating provides outstanding wear-resistant long shank UNC tapping tool life.
