The straight flute tap is a standard, versatile threading tool designed for both through-holes and blind holes. Because its straight grooves do not push or pull chips, it requires the user to periodically reverse the tap's rotation to break and clear the chips. They are generally rigid and offer high thread accuracy.
For tips on how to properly pick and use the right tap for your metalworking projects.
Key Characteristics
Chip Management:
The straight flutes simply hold the chips rather than evacuating them out of the hole. In materials that produce long, stringy chips, you must back out the tap frequently to clear the debris and prevent it from jamming or breaking the tool.
Best Materials:
They excel in short-chipping materials like cast iron. They are also highly durable in standard metals like mild steel, aluminum, and brass, though spiral flute variations are often preferred for gummy, long-chipping metals.
Strength:
Because they have a solid core, straight flute taps are stronger and less prone to breaking than spiral flute taps.
Types of Chamfers
While a tap's "straight flute" designation refers to its grooves, its cutting tip chamfer dictates how the threads are cut:
Taper Taps:
Feature a long lead-in (8 to 9 threads) that gradually starts the thread. Ideal for starting a hole and for tougher materials.
Plug Taps:
Feature a medium lead-in (3 to 5 threads). This is the most common, all-purpose tap.
Bottoming Taps:
Feature a very short lead-in (1 to 2 threads). Used after a taper or plug tap to cut threads all the way to the bottom of a blind hole.
