HS Spiral Point Taps, NC and NF

HS Fractional Spiral Point Taps

Fractional Spiral Point taps. National Coarse and National Fine threads.
High Speed Steel. Ground Thread.

Basic tap types:
Taper tap: 5-6 lead threads ground. The easiest tap for starting to thread a hole.
Plug tap: 3-4 lead threads ground. The most common tap: a "middle ground" tap for threading.
Bottoming tap: 1-2 lead threads ground. Used for continuing to thread a blind hole close to the bottom of the hole. It's difficult to start threading a hole with this tap.
Spiral Point tap: A tap with a chisled point that pushes metal chips ahead of the forming threads.
Extremely useful for tapping through-holes (ie holes that extend through the work).
Often machine-driven.
Spiral Point taps are not recommended for use in blind holes: the accumulation of chips can tend to bind and break these taps more easily than others.

Recommended drill sizes are for approximately 75% thread.

Spiral Point taps have a chisled point that pushes metal chips ahead of the forming threads.
Extremely useful for tapping through-holes (ie holes that extend through the work).
Often machine-driven.
Spiral Point taps are not recommended for use in blind holes: the accumulation of chips can tend to bind and break these taps more easily than others.

Tapfree 2 Cutting Fluid

We have temporarily removed these items from our catalog while we re-organize our inventory.
Tapfree 2 Cutting Fluid.
For all metals except magnesium.
Environmentally safe, water-based fluid.
Used for tapping, milling, drilling, etc.
Quickly penetrates to the cutting edge and reduces friction and heat generated during cutting.
Safer than chlorinated solvents or oils.
Intended to be used full strength (primarily through misting or direct application), and not in recirculators. The viscosity of these fluids makes pumping difficult.

Please note: these cutting and tapping fluids ship by GROUND ONLY !
These products are NOT available for export.
