All good - wanted the 1.25 dia thread instead of the 22mm which seams to be the standard now in metric-was very pleased to find this incn size — will need to look or make adapter to use 22mm core drill bits in my 1.25 machine
The guide bit is useless. Built a rig to line it up. Overall, good value for the money. Have drilled 4 holes through 3 layers of brick each and it's held up well.
Needed it for a one-off job to drill through double brick for a 50mm pipe to go through and the core drill handled the job well. Was shipped quickly too.
thank you makes my job way easier know.https://www.vevor.com.au/hole-saw-kit-c_11426/vevor-dry-diamond-core-drill-3-76mm-dia-hole-cutter-for-concrete-masonry-brick-p_010847462202
