eBay angle drill adapters

I figgured m10 must be a typo

I thought grinders were M14? Or is that 9" ones?

My battery grinder has soft start and a clutch so this looks a good option

4 1/2, 7 and 9 inch ones are but 4 inch ones are a smaller thread.

if its an old property there will be notches , just have to get creative

Sadly it's an old unmolested property, never had central Heating or proper plumbing

drilling the joists is the correct thing to do, I can usually get the Makita with a spade bit or auger in. some times you have to start at a bit of an angle and straighten up as you go

or cut the bit down if the length allows

I guess it also depends on what sort of 150 year old wood it is. If it's oak then you could be in for some fun. When the plumber fitted the central heating in my brothers house they gave up drilling pretty quick as they were ruining an auger bit on every other hole.

even 80 year old joists made from soft wood are hard enough to drill

The house I grew up in was 350 years old, all joists & beams were oak. My father was trying to notch joists for cables & ended up using a lump hammer & cold chisel as it was so hard. He tried to screw into an oak beam to fix something & failed miserably, he ended up drilling & tapping it 1/4 Whitworth.

M6 just wouldn't be right in 350 year old oak

should have bought a good quality auger then instead of some cheap soft rubbish tat that's on the market. now green oak is a different kettle of fish
