TCT countersink Chipboard etc ?

[Ants]

Hi Folks

Any recomendations for countersinks for chipborard flooring.

Cheap ones blunt in no time.

What do you guys use?

Thanks

Screwfix ones with the built in drill and throw them when they get blunt. Cheap enough

I use a De Walt flip driver set (pilot drill and csk on one end, driver on the other). Did a complete house with it and only bust 3 drills.
It does tend to disengage from its collet chuck though.

Famag, their tct ones are superb, they also do a 7 blade one that is HSS so on chipboard it'll blunt but good on softwood.

I use the trend snappy ones, the metric sizes are best as you get a full clearance hole in the board so there is no risk of jacking.
