How to Choose a 70 mm Core Bit

Choosing the right 70 mm core bit is key to precise and safe drilling. For the tool to serve you well and effectively for a long time, several factors should be considered:

Mounting Type of the 70 mm Core Bit

Pay special attention to the mounting type — the 70 mm core bit must be compatible with your equipment. The most common types are M14 and 1/2" UNC. Incorrect mounting can lead to unstable operation or the inability to use the 70mm crown drill bit at all.

Drilling Mode — Dry or Wet

It's also important to consider the mode in which drilling will be performed: dry or wet. Wet drilling requires a water supply, which extends the tool's lifespan and reduces overheating. If you plan to use the 70 mm core bit with a handheld drill without water cooling — choose models designed for dry drilling.
