What is difference between hand tap and machine tap?

"Machine taps" will be defined as those with geometrically designed recesses to guide the chips out of the hole. Spiral tip and spiral groove taps fall into this category. Both "hand" and "machine" taps sold today are made from the same base material and can be used by either method.

The traditional hand tap acts as a cutting tool by removing material from the workpiece. This is done using sharp teeth. The tap rotates in a hole in the workpiece. This hole is called a pilot hole or tapping hole and is sized according to the desired thread and the material to be tapped.

What the difference between a machine tap and a hand tap?

The terms "Hand Tap" and "Machine Tap" don't always mean what you think they do! These are archaic industry "legacy" terms. Originally created to define a purpose, they can be misleading to industry professionals. They should not define the modern use of a faucet.

According to some manuals, the term "hand tap" has traditionally been applied to small size taps with a standard common length. Most manufacturers do not limit the description to decimals. Assumed to be straight-fluted taps, these taps have a groove pattern that provides space to accommodate the chips produced during tap cutting. Some research suggests that the term originated in the early 1800s when most threading applications were actually done by hand. However, when the machine age took a giant leap forward after the 1880s, the term Hand Tap was still used to refer to taps that were unchanged in design and is now used for both machine and manual taps.

Since machine tapping was much faster than manual tapping, chip evacuation became more difficult to control. Machine taps will be defined as those with recesses designed with geometry to guide chips out of the hole. Spiral tip and spiral groove taps fall into this category. These changes in groove geometry have improved tap efficiency. Today, with the increased use of cooling holes and external directed coolant flow in taps, straight fluted manual taps can provide a similar chip evacuation aid, but are still considered by some to be different from machine taps.

Don't get hung up on a name. Both hand and machine taps sold today are manufactured from the same base material and can be used by either method. The decision of which design to use should be influenced by the needs of the job.
