CoroTap® 400 is a high-speed, chip-free forming tap suitable for both through- and blind-holes in steel, stainless steel, aluminum, and HRSAs. Versatile and optimized forming taps are available, with and without oil grooves, in an assortment of diameters, grades, coatings and thread forms to suit a range of applications.
The hole
For basic hole size calculations, use the appropriate formulas for forming taps.
D = Hole diameter (mm, inch)
TD = Nominal thread diameter (mm, inch)
TP = Thread pitch (mm, inch)
The component
When the hole is analyzed, have a look at the workpiece material, component shape and quantity.

Why a forming tap?
There has been a major overhaul of web pages for automotive component solutions.
Choosing the right tap
Select the correct tap based on application material and hole specifications.
Coolant
Coolant is critical to a successful tapping operation. The coolant supply influences chip evacuation, thread quality, and tool life.
