Standard Hob Tooth Profiles as per DIN 3972
| Hfr – Gear Dedendum | α0 – Pressure Angle | HaO – Addendum |
| hg – Working depth of gear | to – Pitch | Sn – Hob Tooth Thickness |
| S0r – Gear Tooth Thickness | r1 – Hob Tip Radius | H4 – Whole depth of hob |
| Tgα0 – Transverse Pressure Angle | r2 – Hob root radius | Pu – Allowance per flank |
| Tooth profile I for | Tooth profile II for | Tooth profile III for | Tooth profile IV for |
| finishing operation | finishing operation | pre-grinding or shaving | pre-grinding or shaving |
| HaO I = 1.167 x m | HaO II = 1.25 x m | HaO III = 1.25 x m+0.25 ³√m | HaO IV = 1.25 x m+0.6 ³√m |
The tooth thickness of the gear is dependent on the dedendum (hfr) :
| hfr = 1.167 x m | hfr = 1.25 x m | hfr = 1.25 x m | hfr = 1.25 x m |
| S0r = 0.5 x to | S0r = 0.5 x to | S0r = 0.5 x to+0.25 ³√m x 2tgα0 | S0r = 0.5 x to+0.6 ³√m x 2tgα0 |
| = 0.5 x to+0.182 ³√m | = 0.5 x to+0.438 ³√m |
