Norseman Drill & Tool Type 38-AGN Metric 30º Helix Angle Titanium Nitride Spiral Flute Semi-Bottoming Taps

Norseman Drill & Tool Type 38-AGN Metric 30º Helix Angle Titanium Nitride Spiral Flute Semi-Bottoming Taps

Norseman Drill & Tool Type 38-AGN Metric Spiral Flute Semi-Bottoming Taps are engineered for precision threading in a wide range of materials, delivering enhanced durability, reduced friction, and superior chip evacuation. Featuring a 30º helix angle and a premium Titanium Nitride (TiN) coating, these metric taps are designed to maximize tool life and improve finish quality in both blind and through-hole applications.

Titanium Nitride Coating for Lubricity and Hardness

The TiN coating applied to Type 38-AGN taps significantly increases surface hardness while adding lubricity that improves chip flow and reduces cutting friction. This results in cooler operating temperatures, extended tool life, and cleaner, more accurate threads. The reduced friction also enhances performance in materials prone to galling or sticking, such as aluminum and stainless steel, making TiN-coated taps ideal for high-efficiency production environments.

Optimized 30º Helix Angle for Superior Chip Evacuation

Ideal for Blind and Deep Hole Tapping

The 30º helix angle, combined with the spiral flute design, provides excellent chip lifting and evacuation capability. This geometry prevents chip packing, lowers the risk of tap breakage, and produces smoother thread finishes. It is especially effective in blind holes where proper chip removal is critical to maintaining thread integrity and tool longevity.

Semi-Bottoming Design for Versatile Threading Applications

Clean, Precise Threads Near the Hole Bottom

Semi-bottoming taps allow threading close to the bottom of blind holes while maintaining easier starting characteristics than full-bottom taps. This makes Type 38-AGN taps well-suited for precision metric threading across various industries, including automotive, aerospace, machining, and fabrication.
