How to use

The hole

For basic hole size calculations, use the appropriate formulas for cutting taps.

D = Hole diameter (mm, inch
TD = Nominal thread diameter (mm, inch
TP = Thread pitch (mm, inch)

  • Drill size for M10 × 1.5 cutting tap = 10-1.5=8.5 mm

The component

When the hole is analyzed, have a look at the workpiece material, component shape, and quantity

  • Machinability?
  • Material hardness?
  • Alloy elements?

The machine

The machine influences:

  • The type of operation
  • Which type of tool holders and/or collets to use

Always consider:

  • Machine stability
  • Spindle speed
  • Coolant volume and concentration
  • Workpiece clamping

Tool holding

The CoroChuck™ 970 is designed for stable and precise tapping in all materials. It improves tap tool life, surface quality, and offers the highest process security.

Coolant

Coolant

Coolant is critical to a successful tapping operation. The coolant supply influences chip evacuation, thread quality and tool life.
