1/4-20 UNC Spiral Flute Threading Tap – Uncoated HSS, H2 Tolerance

Cut clean, precise threads every time with this professional-grade 1/4-20 UNC Spiral Flute Threading Tap. Machined from High Speed Steel (HSS) with an H2 tolerance rating, this tap delivers consistent accuracy for metalworking enthusiasts and seasoned machinists alike. Whether you're working on a hobby project or a production run, this tap is built to handle the job.

Key Features

  • Standardized 1/4-20 UNC Threading: Conforms to the widely used UNC thread standard with H2 tolerance grade for precise, reliable thread cutting every time.
  • Spiral Flute Design: The upward-curling spiral flute geometry efficiently evacuates chips as you tap, producing cleaner threads and enabling faster, smoother tapping in blind holes.
  • High Speed Steel (HSS) Construction: Engineered for high hardness, excellent toughness, heat resistance, and outstanding wear resistance — ensuring a long service life even under demanding conditions.
  • Uncoated Base Substrate: No additional coatings mean this tap excels as a general-purpose threading solution, ideal for a broad range of materials.
  • Wide Material Compatibility: Designed for use on aluminum, die steel, stainless steel, bronze, hard plastics, and other sticky or tough materials.
  • Machine Compatible: Suitable for use on drilling machines, tapping machines, CNC machines, and milling machines. Use with tapping oil for best thread quality and extended tap life.

Frequently Asked Questions

Q: What materials can the 1/4-20 UNC HSS spiral flute tap be used on?

A: This spiral flute threading tap is suitable for a wide range of materials including aluminum, die steel, stainless steel, bronze, hard plastics, and other sticky or tough materials. Its HSS construction gives it the hardness and toughness needed for demanding metalworking tasks.

Q: Why choose a spiral flute tap over a straight flute tap?

A: A spiral flute tap is specifically designed to push chips upward and out of the hole as you tap, making it ideal for blind hole applications where chips cannot exit from the bottom. This results in cleaner threads, reduced clogging, and a smoother overall tapping experience.

Q: What machines is this tap compatible with?

A: This 1/4-20 UNC threading tap is compatible with drilling machines, tapping machines, CNC machining centers, and milling machines. For best results and to extend the tap's lifespan, always use an appropriate tapping oil or cutting fluid during the tapping process.

Q: What does the H2 tolerance grade mean for this tap?

A: H2 tolerance grade refers to the allowable dimensional variation of the tap's threads. It indicates a tight, precise tolerance range that ensures the cut threads will mate accurately with standard 1/4-20 UNC fasteners, providing reliable thread quality for both commercial and DIY metalworking projects.
