Carbide Micro Drills

TIP: Broken micro drills can be used to make carbide gravers and scribers

Description

These very hard carbide micro drills are a cheaper alternative to our superior carbide spade drills. Excellent for drilling through all hard metals. Ensure a steady hand when using these drills.

How to use our Carbide Micro Drills

Most horologists find the easiest way to use them is by first finding the centre with a graver and then holding a micro drill in a pin-vice and then taking them to the work. Use very light pressure whilst taking the drill in and out periodically. No lubrication is necessary although a small dab of oil can help. Extra care is needed with these drills.
