Solid Hardwood, Engineered and Laminate Flooring - T-Moulding on Concrete

I am installing the T-Moulding on my laminate to connect to Tile. I tried to drill the holes in the concrete sub-floor and literally burned two brand new Bosch Masonry drill bits. I am using a Dewalt variable drill. What should I be doing differently?

Are you keeping the RPM's way down?

not really..pretty much just as fast as it would go

I'm no expert but I remember that with metal slowing down the bit makes all the difference. If it heats up it loses it temper.

Hi Tom

That can be very frustrating hey! The best way to drill into concrete is with a hammer drill. We use a Hilti for all of our drilling, they are expensive but I use it every day and they are super fast.

You could either hire one for an hour or so or you could do the following -

Grab a tube of Liquid Nails and some heavy weights (books, bricks etc). Make sure you have at least 1 inch space between the tile and the laminate to allow for the expansion space. Pre-fit the t-moulding to make sure it fits right up against the tiles. Then apply the Liquid Nails to the tiles and the concrete right next to the tiles. Make sure you have 1/2 to 3/4 inch of space with no glue so it doesn't touch the laminate. Then put in the t-moulding and press it up to the tiles. I usually lift it up a little to make sure the glue is nowhere near the laminate and I still have a 1/4 inch expansion gap. Then put the weights on it and leave it for a day. This will hold extremely well. We have to use this method when we install over in floor heating.

Hope this helps.
