Special Drill Bit

danjo-xx

Is there a special drill bit for drilling through 2" timber batten and straight into concrete wall.

Man fitted side gate posts doing this, but any time i used an ordinary masonary bit it was hard going to get thru the timber and not worth the effort.

Quite possible better drill and much better power. You could use wood bit 1st the drill with masonry

Yeah..... I reckon you hit the nail on the head there:D thanks.

Use a normal drill bit to app. 3/4 way through the thickness of the post using masking tape or insulation tape around the bit as a guide (stop).
Then follow with the masonary bit to complete the job.
Hope that is a help.

Tradesmen usually change bits regularly. Personally I spend 750 to 1000 Euro per year on 6mm drill bits. I find a lot of diy guys keep the same bit for years. For me time is money, if I find it slowing going through tiles I bin it and take out a new one

If you have a lot of fixings to make like this, then use an SDS drill and invest in a longer bit - they come in various lengths

Yeah it can be done but you'll blunt the masonry bit quicker, prob no a problem if only regular DIY'er. I'd a load of timber battens to fix to a brick wall recently and it was honestly so quick to do even swapping between two drills. (Cordless with wood bit and SDS with masonry straight through same size hole - was using concrete easy-drive screws so no messing around with wallplugs)

thanks lads, was thinking of doing it this way with hammer fixings. Only have two 5ft 3 x 2 battens to fit. I like this way as there is no messing around with the screwdriver bit slipping out of the head when trying to get it in fully.

8mm SDS bit straight through battens and into wall with hammer action on. I wouldn't be arsed switching bits. No messing with bits or lining up holes.

You could just buy a cheap as chips hss drill and go through the wood until you touch the concrete/stone. Bin it when you're finished doing the wood. Easy to follow through accurately with a masonry bit then.

As stated and SDS drill is all you need, with a long masonry bit it will fly through timber. I rather like the Hilti masonry bits that have small cutting wing on the edge of the carbide that is for drilling through concrete with reinforcing bars they make a slightly cleaner cut than ordinary SDS masonry bits.

It depends how neat a job you want done.
masonry bit not designed for timber, same as golf club not designed for hurling.
I drill 0.5mm wider diameter in the timber with a timber bit and then use the long mastery drill bit
