4. Geometry & Application Insights
-
Spiral Point (Gun Taps): Pushes chips forward. Best for through-holes.
-
Spiral Flute (35°-45° Helix): Pulls chips out of the hole. Best for blind holes.
-
Straight Flute: General purpose. Best for short-chip materials like cast iron.
5. Surface & Material Selection
-
HSSE-M35 (5% Cobalt): Essential for heat resistance when tapping Stainless Steel (304/316) and high-tensile alloys.
-
TiCN Coating (Dark Grey): Provides extreme surface hardness (3000 HV) and low friction, perfect for abrasive or hardened materials.
-
Steam Oxide (Black): Retains cutting oil on the tap surface, preventing chip welding in soft steels.
6. Professional FAQ
Q: What is the difference between Metric Coarse and Metric Fine?
A: Coarse threads (e.g., M10x1.5) are standard for most assemblies. Fine threads (e.g., M10x1.0) have a shallower thread depth and provide better vibration resistance and adjustment precision.
Q: Do you offer custom TPI or Pitch for special projects?
A: Yes. As a factory, we can manufacture non-standard pitches (e.g., M14x1.0 or special UNS threads) upon request with low minimum order quantities.
