Question about Drilling

[ocoma123]

I have a quetsion for the pros... I Know Delta kits you will rarely have to drill a chip. If I do have to drill a chip I see dont drill too far ect....What is to far? How do I tell as I do not want to drill the laminate? I have not seen much info on far or deep to drill? Is it 1/8 OF AN INCH.. Can a pro explain...? thx

Hi - You can find a lot of information on drilling by typing the word "drill" or "drilling" into the search bar. Drilling is a common topic on this forum and there is a lot of input and information from members.

I use the drill to more less clean out the impact area.I do not use delta but I try not to drill unless a star is being stubborn.When you drill you don't want to hit the laminate but if you do it is not the end of the world.This comes with lots of practice and many repairs.delta has that spring hammer that actually has a gauge in the top of it on how far to drill to pop a bullseye.Hope that helps some.

Time to dig out the practise screen again and get practising. I have been using the drill as a powered scribe since almost the beginning of time it seems, this does not mean that I drill in or deep.

How deep depends on the type of break, also truck or car glass. On a car very slightly more than the head on a round end bur, on a truck a bit more. Not much help I know but to be honest only plenty of practise breaks in real windshields ( not customers one's) will let you know how far to go.

When your drilling into your practice shield, purposely drill into the lami. Just before you get through first layer of shield you'll notice or feel dremel speed increase. Same happens when your drilling a hole through a piece of wood. The closer you get to drilling through it, your drill speed will increase. (less resistance or friction) Something you need to practice on and get a good feel for!

If you have a scrap piece of windshield, look at the edge of it to see how thick each layer is. Hold the drill against the edge and make a mental note of where the laminate begins. Half way thru the glass should be deep enough.

Guys...

Delta Kits - 22000 Spring Hammer Depth Guage $6.65

No more drilling into the laminate! This replacement depth gauge for the spring hammer allows you to drill consistent holes when repairing windshields. Get perfect bull's eyes every time when stopping long cracks.

Just remember that glass thickness varies and the tendency is for glass manufacturers to go thinner and thinner, for various reasons. One of the thinnest screens I've ever worked on was a Ferrari 308gtb. The glass used was not much thicker than the interlayer itself.

If you have a star with legs that you are having a problem filling, then it's a good idea to drill Into the legs to open them up. Drill at an angle into each leg and never drill deeper than half the length of the burr then you won't hit the laminate.

I'll have to disagree with this method. I seldom find the need to drill into star legs to fill. This is when you have to use your probe to flex them open. Nothing looks worse then having 4-6 drill marks in one repair. JMHO
