Summary
The APEX Design USA 12.5mm Drill Bit is the install tooling for APEX kits that specify a 12.5mm hole. Buying the correct bit with the kit means the install never stalls at the drilling stage - and holes in structural parts get drilled once, at the right size, first time.

Fitment And Setup Checks
Check your kit's install instructions to confirm the 12.5mm size is specified before ordering. Centre-punch, drill square and deburr - the usual rules for a hole you only get one go at. Use cutting fluid and steady speed in thicker steel so the bit lasts well beyond one install.
