The quality is okay, the drills do what they want, they drill. The drilled Löchers be round and not ovate. The holes in the template have the correct diameter. The drill is performed cleanly and at right angles.
The depth stops sit rock solid on the drill and did not move!
So paaaaast scho!
The case is stable and does what from. At least that what's inside that remains indoors and not unwittingly tumbles out!
Hot tip:
After use, I clean the drill with a paper towel or similar After spendieren a drop of oil and spread evenly.
