Currently (last tested on pack version 1.5.x), all of the below items are either not reforgable or cost flint to reforge, which, in the latter case, feels too cheap for my taste.

To change this, I suggest the following material costs for reforging the more advanced tools from MI:

• Steam Mining Drill
  • Preferred: Copper Drill Head
  • Alternatives: Diamond or Iron Large Plate
• Diesel Mining Drill
  • Preferred: Aluminum Drill Head
  • Alternatives: Electronic Circuit, Large Pump or Large Motor
• Diesel Chainsaw
  • Preferred: Invar Rotary Blade
  • Alternatives: Electronic Circuit, Large Motor or Large Pump
• MI Wrench doesn't need reforging.
• MI Config Card doesn't need reforging.

An example file is provided in #342, just replace the item IDs in product.id and base[0].id as appropriate.
