Spiral Point Tap (Gun Tap)
-- Steady & Reliable Manufacturer --
Product Overview
This tap has its cutting point ground at an angle so chips are pushed forward, ahead of the tap, rather than curling back into the flutes. That makes it well suited to through-holes on CNC machining centers and high-speed production tapping, where fast, uninterrupted cutting with predictable chip flow matters more than working in a blind hole.
We supply this tap to CNC machine shops and production tapping lines that need consistent thread quality at speed, across common metric and unified sizes in HSS and cobalt (HSS-E) grades.
Specifications

Application Fields
- ✓Through-hole tapping on CNC machining centers
- ✓High-speed production tapping lines
- ✓Aluminum and mild steel through-hole threading
- ✓Automotive component machining
- ✓General machine shop through-hole production runs
- ✓Tooling distributor resale to CNC shops
Key Advantages
- Forward chip evacuation keeps chips out of the flutes, reducing the risk of chip packing and tap breakage in through-holes.
- Suited to high-speed CNC tapping cycles, since chips clear ahead of the tap rather than needing to be pulled back out.
- HSS-E (cobalt) grade option extends tool life in stainless steel and harder alloy through-holes.
- Coating options (TiN, TiCN) reduce friction and extend tap life in production runs.
- Standard shank dimensions make it a drop-in replacement in existing tap holders and CNC tooling.
