Left Hand Taps - Solid Carbide
page 217B
Micrograin Solid Carbide Hand Taps are designed for threading difficult to machine materials and tough work hardening metals such as stainless steel, titanium alloys, Iconel, powdered metals, cast iron, plastics, and steels up to Rockwell hardness C45. Used whenever high speed steel hand taps cannot handle the job. Solid Carbide Hand Taps must have a rigid setup for use.

Left Hand Tandem Style "Acme" Thread Taps
page 221C
High Speed Steel Tandem Acme Thread Taps are designed with
a roughing and finishing section to produce threads from a 10
degree to 30 degree included
angle in a single pass without a leadscrew. The last few threads
on the roughing section act as a guide for the finishing section,
which corrects the thread angles and size. The original purpose
of Acme threads was to convert rotary motion to traversing motion
on machine leadscrews, valves, jack lift screws, drive gears
and other mechanisms where heavy loads are encountered. They
have four flutes and are to be used for through holes only. Designed
to produce a class 2G thread fit.

High Speed Steel Tandem Acme Thread Spiral Flute Taps are designed
with a roughing and finishing section to produce threads from a
10 degree to 30 degree included angle in a single pass without
a leadscrew. The last few threads on the roughing section act as
a guide for the finishing section, which corrects the thread angles
and size. Spiral Fluted Tandem Acme Thread Taps have continuous
spiral flutes to lift and discharge chips in deep holes. They
have black steam oxided flutes to improve finish and produce a
class 2G thread fit.
Left Hand Thread Pipe Taps
page 233
High Speed Steel Left Hand Thread Taper Pipe Taps are designed
to cut taper pipe threads with a left hand rotation and are used
in applications where left hand pipe fittings are needed. Left
hand threads are also used to secure rotating parts where regular
rotation would tighten the coupling.
