Core drill purchase

[Andy78]

6" is 152 though (ive got a set of digital calipers to hand)

2" holesaw is 51mm so 6" is 153ish as a rough measure

What I'm saying is that the stated fan diameter does not necessarily correspond with the outside diameter of the ducting used therefore a larger core drill diameter is usually required.

If you rotate the core drill Inside the empty hole it will gently increase the size to allow for sold ducting. Drill on a bit of an angle an chamfer it around so too speak.

I use one of the Milwaukee dedicated core drills and it's a tank. I've probably done 300+ with it. 4,5,6" is what's it's ideal for. It's very power and reliable. Watch your wrists though because when it catches it's like wrestling a stuck pig. I would personally buy an engineering core drill as it's quicker and less prone to jamming. The ones with the dust extraction vent on the side bite constantly. Wear ear defs and gloves because you need them

Do you use a hex adaptor for that or an sds one?

All along the length of a 12" long hole ? I'd rather use the correct size core and spare my clutch the torment.

Hex adapter mate, the chuck is really good. It never loosens or starts sticking.

did your core set not come with an sds max adapter?

Or slice along the ducting length and curl it inside of self. These days with the old imperial measurements being used you would need about 4 different sizes of each core drill.

Also thought the makita was weak , took much longer to core than the milwaukee which had tons more power .

Both these drills were borrowed and i wouldn't be surprised if the milwaukee was twice the price .

I have since purchased a metabo (can't remember the model)second hand for £100 it is solid with similar power as the milwaukee but has no clutch :wheelchair:
