Spiral Hss Taps Straight Gun Point M6 Spiral Flute Tap 4in - 1.5in
High-Performance HSS-E M35 Machine Taps | Spiral, Form, Straight, & Gun Point Taps | M2-M52 & ANSI #4-1.5"
1. Introduction: The Four Pillars of Threading Excellence
Our HSS-E M35 (5% Cobalt) Machine Tap Collection offers the ultimate solution for any threading challenge. By selecting the correct geometry from our four core designs, you can optimize chip evacuation, thread strength, and tool life across all industrial materials, including Stainless Steel (304/316), Alloy Steels, and Non-Ferrous Metals.
-
Spiral Flute: Best for blind holes (pulls chips up).
-
Form Tap (Fluteless): Chipless threading for ductile materials (strongest threads).
-
Straight Flute: General purpose and short-chip materials (cast iron).
-
Spiral Point (Gun Tap): Best for through-holes (pushes chips forward).

4. Strategic Engineering Selection
-
Blind Hole Solution: Use the Spiral Flute (35°-45° Helix). It acts like a screw conveyor to pull chips out, preventing tool breakage at the bottom of the hole.
-
Through-Hole Solution: Use the Spiral Point (Gun Tap). The angular point shears chips and shoots them forward, keeping flutes clear for high-speed operation.
-
High-Volume/High-Strength: Use the Form Tap. It creates threads by plastic deformation. Ideal for Aluminum and soft Steels; produces no chips and significantly stronger threads.
5. Material & Manufacturing Quality
-
HSSE-M35 (5% Cobalt): Provides the thermal stability required for work-hardening materials like Inox.
-
CNC Fully Ground: Every thread is ground from solid hardened steel to ensure 6H/Class 3B precision.
-
Anti-Rust Protection: Vacuum heat-treated and oiled for a 36-month shelf life.
6. Professional FAQ
Q: Why are there no flutes on the second tap in the image?
A: That is a Form Tap. It doesn't cut; it displaces the material to form threads. It is the best choice for chipless tapping in ductile materials.
Q: Can I use the Spiral Point tap for a blind hole?
A: No. Because it pushes chips forward, the chips will clog at the bottom of a blind hole and likely snap the tap. Use the Spiral Flute version instead.
