Tap drill, clearance hole & fit charts

Every catalog number, one table per chart - tap drills, clearance holes, heat-set pockets and bearing fits, in metric and imperial. Each row links to that size's full page, so a chart is both a quick lookup and a way in to the detail.

These are standard reference numbers. Every machine prints and cuts a little differently - set a hole to Ø5.00 and it might land at Ø4.95. In the FitCheck app you calibrate your machine, and the clearance and pocket diameters here shift to match it - plus tolerance bands and full offline use.

Metric and imperial clearances follow published mechanical-engineering references · heat-set pockets per CNC Kitchen · bearing housing seats follow published fit tables. Reference only - verify before you cut.
