Triassic Posted February 20, 2019 Posted February 20, 2019 I’ve just started first fix plumbing, by drilling holes in the timber frame for the pipes, using my old but trusty spade bit. Three holes later and it’s blunt! I’m thinking I need something better, but what? Can anyone recommend a make of good quality wood drill bits?
dpmiller Posted February 20, 2019 Posted February 20, 2019 I got a Bosch Daredevil bit a few months back and it fair chews through wood on the impact driver. Nasty thing.

"old but trusty spade bit"--think thats says it alL have you sharpened it ever?--try that while waiting for new goodies# the type suggested are superior no question about it Edited February 20, 2019 by scottishjohn
PeterW Posted February 20, 2019 Posted February 20, 2019 Depending on the size of hole, I use either Armeg ones or a decent lip and spur drill bit. Make holes for 15mm pipe a 20mm minimum and you won't snag or score when pulling Hep2O through the joists.

Crofter Posted February 20, 2019 Posted February 20, 2019 Another happy Armeg Beaver customer here. I've got the one, a 12mm, but it has done a ridiculous amount of work for me. The ring beam that my house sits on is made of two layers of 75mm douglas fir, sistered up, and held together with literally hundreds of 150mm bolts. The Armeg in my impact driver drilled every one of those holes, no sweat, and continues to be my best and sharpest drill bit. In fact I think I may have just talked myself into getting a full set of them...
Triassic Posted February 21, 2019 Author Posted February 21, 2019 Whilst on the subject of drilling holes in wood. The MVHR duct pipe needs installing next, what sort of drill you all use to drill through the studs etc?

OK on thinner material, like Steico Web.
Triassic Posted February 21, 2019 Author Posted February 21, 2019 From what I’ve read the plastic flexible duct is 83mm in diameter. Holes to be drilled mainly through 50mm Studs.

The majority of it is 75mm OD, 63mm ID, although there is one brand that's 83mm OD, not sure it's that commonly used though, as there are half a dozen suppliers of the 75/63 stuff.
