"Bought these today in order to cut some 15mm plugs to fill reudendant holes left by and old radiator. I agree they need a fair amount of pressure on the drill to get them to cut through and my wood did start to burn. The end result i did get a decent plug which i've been able to use. Hve not used any other plug cutters to be able to compare but would have hoped these would work their way through the wood without needing to apply so much pressure.... But maybe thats how they are intended to work."
"I'll be returning these at some point as all the do is burn through ANY wood. I wanted to plug some Mdf holes but all it did was nearly set the house alight!! Even on slow speed and the correct drill they were terrible!! What waste of my money and time."
"If you're thinking about buying these cutters, don't do it, they are worse than useless. Even on a pillar drill at slow speed with a clamped piece of oak they're shockingly bad. To say they're blunt is an understatement, but if you like the smell of oak burning these cutters are for you!"
"I tried to use this on pine skirting board using a mains B&D power drill. It barely cut the hole - in fact it mainly burned it's way into the soft wood. I gave up and had to countersink the screws instead of hiding them with plugs. I tried 2 of the 4 in the set and both gave same poor performance. Will be taking them back to Screwfix."
"I bought a set of these to cut some plugs from Oak. Unfortunately the size being used only lasted five plugs before going up in smoke. This was when being used as directed on a pillar drill at a slow speed. I will return them tommorow. Perhaps Screwfix should source a higher quality set of bits as I'm sure the demand would be there for them. I would certainly pay more. Probably perfect for use with soft pine etc."
