Bit for offset calibration and jointing

Hi folks,

Can someone provide the geometry of the 3/8 jointing bit required to calibrate offsets? Is it the 3/8 x 1 1/4 straight bit in the profile set available from the CarveWright online shop? Is in the same as the jointing bit?

Thanks a bunch,
Andy D.

Yes Andy I believe it is.

Belated thanks!
