Yes, You are right @Anthony Hormenoo.

You are right @Mahanta.
The Depth of cut is the depth of the hole we made in drilling.

Here it is (D+t) /2.

Depth of cut is half of the diameter of hole. So depth of cut is 10 mm.

Depth of cut is D/2.

Agree @P Das.

I totally agree @P Das.
The depth of cut of the drill is half of the diameter of drill thus the other parameters are a source of confusion to us.

0.5d is not a depth of cut it is a cap means compulsory approach angle.

For through-hole depth of cut is 0.5D and for the blind hole, 0.3D, here D = 20mm and the case of through hole, so the depth of cut = .5 * 20 = 10mm and depth of cut are not equal to the depth of the drill to be produced.

Depth of cut is equal to the half of drill diameter. So depth of cut is 20/2=10mm.
