How Do Spiral Taps Help with Chip Evacuation During Tapping
2025-11-13
Anyone who has spent time on a shop floor knows the frustration of chip-related problems during tapping. Jammed chips can lead to poor thread quality, tool breakage, and costly downtime. This is where the advanced design of Spiral Taps truly shines, especially the high-performance models from NERES. Unlike standard straight-flute taps, Spiral Taps feature deep, helical flutes that act like a conveyor system. As the NERES Spiral Tap rotates and cuts, this helical geometry creates upward suction, actively pulling chips out of the hole and away from the cutting zone. This fundamental design principle is the key to cleaner threads, longer tool life, and uninterrupted machining.
The effectiveness of a Spiral Tap is determined by its precise engineering. NERES has refined these parameters to deliver superior performance.
Key Features of NERES Spiral Taps:
-
Optimized Helix Angle: Our specific helix angle is calculated for efficient chip ejection without sacrificing tap strength.
-
Premium Sub-Micron Grain Substrate: Manufactured from the finest materials for enhanced wear resistance and durability.
-
Specialized Surface Treatments: An advanced TiN coating reduces friction and built-up edge, further smoothing chip flow.

Spiral TAPS FAQ Common Problem Guide
What materials are NERES Spiral Taps best suited for?
Our Spiral Taps are exceptionally versatile. They perform brilliantly in stringy and gummy materials like stainless steel, aluminum, and low-carbon steels, where chip control is most challenging.
Why does my spiral tap still break in deep blind holes?
Breakage often occurs due to chip packing at the bottom of the hole. Ensure you are using a Spiral Flute Tap, not a Spiral Point tap, for blind holes. Furthermore, verify you are using a sufficiently powerful coolant through the tool system to work in concert with the NERES Spiral Tap's evacuation action.
Can I use a NERES Spiral Tap for through-hole applications?
While Spiral Flute Taps are primarily engineered for blind holes, they can be used for through-holes. However, for through-hole tapping, a Spiral Point Tap (or gun tap) is often more efficient as it pushes chips forward and out of the hole ahead of the tool.
