[Scorpion]

I've been trying to drill my zorst to no avail, :o what kind of drill bit do i need.....or are my drill bits worn out as they dont seem to be doing anything. :)

[Monster-Mat]

a normal HSS bit should do it no problem

[Scorpion]

HSS.........

[T7RY B]

Ordinary steel bit should do it. Just centre punch it first. Check your bit isn't worn out

[Brettster]

HSS.........

High Speed Steel

Scorpion make sure you have a good sharp hss drill bit, then use some lube like cutting oil and drill at a slow speed, to fast and you'll just burn out the drill bit. Depending what size hole your drilling you could put in a pilot hole first, hope this info helps cheers Steve.

Cheers peeps.

Wait till you see what im gonna do with my zorst :shutit:

thats what i was thinking he was gonna do...............

[Scorpion]

Nope......

[Dr Evil]

Are you going to make lots of big holes a la motorcycle exhaust?

[Scorpion]

Nope..

[Monster-Mat]

are yo adding a flap into the exhaust system, to port the exhaust gas flow out of a shorter more direct exit, thereby decreasing the back pressure at High RPM

[Scorpion]

Nope....but when your behind me you'll know its me instantly :winky:

[Lexus Jim]

are you gonna cable tie a rubber chicken to it?

[SHAHZ]

:shutit: hes gonna put LEDs on it

[Dr Evil]

Nope....but when your behind me you'll know its me instantly :winky:

Is there going to be a 'sting' in the 'tail' ?!

It's one of these isn't it

1. Make sure the bit you are using is very sharp

2. Always centre punch the hole to be drilled

3. NEVER drill a hole in S/S more than 4mm without firstly drilling a pilot hole.

4. Keep the cutting speed low.

5. If you are drilling into the polished end of an exhaust - use a coolant, and only apply moderate pressure - otherwise you will scorch the steel and it will go blue.

Never attempt to drill without the centre punch otherwise the drill bit will dance across the piece and scratch it, not to mention possibly slipping of the piece altogether risking further damage and possible personal injury.

Always wear suitable eye protection

If the swarf is coming away is very small splinters, then your drill bit is not sharp enough. Use a new, quality drill bit, preferably a Presto Bit, none of your cheap rubbish as they are not hardened sufficiently.

Try and mount the piece firmly in a vice or clamped to a bench, so you can free up the other hand to steady the drill and keep the pressure light.
