They can be used in all high-speed rotary tools such as Dremel, Foredom, Ryobi, Fuller, Ozito GMC, etc. Note that depending on the size drill bit you choose you may need an accessory 3 jaw chuck instead of a collet.

TIPS FOR BEST RESULTS
- Always use a coolant (usually water in a spray bottle) when drilling.
- Using a drill press is easier to keep the bit straight and avoid breakage.
- Twist drills can break when you least expect it so always wear safety glasses.
- Take the drill bit out of the hole frequently and flush with water to remove debris.
- For some drill sizes you may need to use an accessory 3 jaw chuck instead of a collet in order to firmly hold the drill bit.
- Do not force the drill bit, let the diamond do the cutting and drill at a slow to moderate speed. Drilling too fast will just wear off the diamond plating prematurely.
- Oil after use to prevent rusting.
