An ovolo router bit cuts a rounded edge profile, while BVF also lists the 9-Jacks 9945 as a 14 mm, 45° V-shaped bit. The Universal ovolo codes 259–266 have listed cutting diameters from 10 to 38 mm and an 8 mm shank; use the code chart to compare the two dimensions.
Router bit code and size chart
The cutting diameter and shank are separate fields in the Universal descriptions. Read both when comparing a bit with your job's tooling specification. The chart reproduces the listed figures rather than inferring a shank from the product title.

Ovolo: compare the code and diameter
Universal describes its ovolo bits as cutting a rounded profile on the edge of the material. Code 259 lists a 10 mm cutting diameter; code 260 lists 12 mm; code 261 lists 15 mm. The same series continues through 19, 22, 25, 32 and 38 mm cutting diameters. Each of those descriptions states an 8 mm shank.
V-shaped: check the angle field
The 9-Jacks 9945 description lists a 14 mm cutting diameter, 9 mm cutting height and 45° angle. Treat those as the listing's separate specification fields. Request a drawing if your job needs confirmation of how the stated angle is defined.
