Questions and Answers
1 Questions
How long are the 1 - 4" core drill bits that come with this kit
And what is the max length of a core drill bit that can be used on this rig
The drill bit has a working length of 390 mm and a total length of 455 mm. If you need to drill deeper holes, you will need to purchase an extension rod. The safe drilling depth is 600 mm; the extension rod should not exceed 200 mm in length, as a rod that is too long will cause excessive vibration, which can lead to off-center drilling and damage to the drill bit and equipment.
