Carbide Drill Bits for Jets

I just received a set of carbide micro (wire) drill bits which I will use to straighten jets which are not perpendicular. This will help especially when peening the lipstick burner too much ...or cleaning I guess

 

Hi Ron, what size are these drills? And where does one find these? They look a bit like dentists drills to me

Regards,

Wim

 

Hi Wim, I get this locally. Looks like dentists drills but they are from a hobby shop where I order them. These are .0091". What size are you looking for? PM me.

 

Yeah, Ron, where can we get some of those? They look to be of very high quality.

Sam, Google DrillBitCity as they specialize in micro drill bits in inches and mm. Address it to Paul. His email is: pstonis@comcast.net

Ron

 

ok. I'll go have a look. Thanks.

 

Hi Ron, I was thinking about both nipple sizes, .23 & .32 to clean-up old ones, and as you mentioned, to restore the lipstick burner on my 96.

Regards,

Wim

 

Hey Wim, he has close to that but not exact I got the slightly smaller size since it will not be exacting rather than the larger size. The closest to the .23mm would be the #88 which is .22++mm but its a bit pricey as it is brand new. I just got the resharpened one and that will work for me.

 

Wim, check your email. Sent you the sizes

Sam whats your email again?

Ron

 

Maybe I should pay a visit to my dentist! Problem is, my teeth are allright for the moment so it might take a while... . Sure these must be for sale this side of the big water too, next time I go to the big city I'll look out for hobby shops and ask for them .

Regards,

Wim

 

Thanks for the e-mail Ron! If I can't find them over here, I'll get in touch!

Kind regards,

Wim

 

Recently bought these; 10pcs x 0.45mm (0.018"), on 3mm shanks, from ebay seller tools852

£8.49 all up.

Haven't used them yet but if they only work once they will be a good buy.

 

I only ordered the jet sizes as I have no need for other sizes. But its a good investment as I plan to make alky stoves too with the bits.

 

Hi lads,

because of my poor english I can't get proper name of the material.

are they made from TiC/WC (titanium carbide or similar) or from carbon steel(or HSS)?

TiC/WC is realy fragile, hss is better, just an opinion 8-[
or you are looking for a big tang?

 

Hi Grigoriy, the bits are made of micro grain tungsten carbide.

Ron

 

Beware of these drills they are very very brittle, I tried drilling with them in a lathe using very little pressure and broke two of them easily, I think it would be better to use Hi speed steel as I resorted to with no problem. High speed steel drill bits can be bought from Chronos tools, I used the .3mm bit to make a new 96 lipstick burner. I had to drill a tiny hole in a short length of 1/8 brass rod and glue the tiny drill bit in with epoxy as my drill chuck would not grip thr tiny bit.

 

Yes the Carbide Bits are brittle and should not really be used with high speed drills. I normally have just the small one hand pen like bit holder and turn it back and forth. You would expect it that way since it is quite thin. Do not expect to use is in big drills as the weight of the drill alone can cause it to break. This also applies to HSS drill bits of .20mm to .40mm

 

have a look in a shops dealing with a jewellery instruments.

such a bits are often used with a special conductors-thick walled TiC/WC or hss tubes.

 

Acetylene welders use very small drill bits, to clean their jets. Not sure of the sizes tho...

 

I have one of those Acetylene files for cleaning tips but the smallest is still too big for the stoves but can be used to clean trangia alky stove holes.
