Sizes: see table below
- A 55 × 13 block with R3 rounded ends; a Ø22 pocket (608 OD) runs through the 13 mm thickness on an axis 15 mm above the base.
- Two Ø5.5 holes (M5 clearance) through the base, 42 mm apart.
- The file is 25 mm tall. The catalogue KP08 housing stands 29; the top 4 mm is not drawn on this file, so the Ø22 pocket breaks out through the top face as a 9.2 mm wide opening.
- The 608 sits in the Ø22 pocket and carries a Ø8 shaft; the fit is listed under Mating features.
