Can these drill through a car's trunk without any issues?

These are made to drill through thick hard steel. Thus are very hard and brittle and will break easily if improper angle is applied. For drilling trunk or locks use a titanium bit and buy a few of them as they dull quick but get the job done.

Bought the 19 pc set; 3mm but broke immediately. Can anyone point me to where I can buy replacement? Thank you.

Can they drill titanium

Honestly,They are good for drilling steel and do the job well. But Titanium alloy has very high hardness. And We can't guarantee. If it doesn't work well, you could return it. If it works（Lubricant Must Be Used）, you could share it with other customers.

What is the length of these bits?

They are average lengths. The 1mm is 3.4cm and length increase proportionally to the 10mm which is 5.4cm.
