i'm looking for advice on makeing as thin as possible cuts in some tool steel or drill rod, i am flexable ( a little ) on material i need to either harden it or get hard stuff from scratch

this small stuff has me a but bewildered and i am out of my depth in the smaller area

is there such a thing as a diamond disk or similar for dremel tools? sub millimeter wise?

or am i barking up the wrong tree?

ideally i would like a 0.4 mm (0.0155") cut is such a thing possible??

if not what is the thinnest i could xpect to be able to get without buying a water jet

i need to be able to do this on a budget

cheers

How about a slitting saw? You can buy a solid carbide slitting saw down to about .01" thickness. They are, however, quite expensive! MSC direct wants about $175 USD for one.

A high speed steel slitting saw would cut drill rod with no problem and those can be had for a lot less money.

Hi Jack

(I've waited a long time for that one....)

There are 1/64" (0.04 mm or 0.0156") cut-off disks available for the dremel. I buy the house-brand ones at the local big-box hardware in tubes of 30. They are really not at all tolerant of any side loading, so getting them in large numbers is a good idea for me. (I can send you a lot of pieces of them if I sweep up my shop floor....)

Cheers, Joe
 
We could use a lot more information on what you're trying to accomplish to give better advice about how to go about it. What does the finished part look like? Why are you making these fine cuts?

etc.

real budget - Jewellers saw. Blades come in a variety of sizes.

Use these fellas myself, now they DO come in an assortment of sizes from fine to very very fine, but there is a catch to them as well.

They are NOT recommended to be used on STEEL, let alone DRILL ROD or TOOLSTEEL, been there, done that, seen that movie and dont like the ending.

The material that the blades are made from is CARBON STEEL heated to about 56-57 ROC.
When attacking said above materials, they will make a few advance cuts into the material, then the edge is taken from the teeth real quick, so you attach a new blade and take another couple of cuts, then you replace the blade once again and keep going like this, many blades later, you might happen to cut through.

As you can see by the hardness, they are ONLY meant to be used on softer materials. They will cut through MILD STEEL, like what a nail is made from, so long as you keep the blade waxed and dont let it get hot, by that I mean make the cutting action slower than you would on brass, then you can attack a low grade of steel, but it aint recommended.

Here's a bit of info to look at, now the metals the advert is referring too is gold, silver, copper, brass, stuff that's soft.

G'day folks and thanks

Chuck, Joe thank you i'm going to try both of these to check results but will most lilely do both,

one project i have is a steady holder for my dremel, sort of a mini mill with the dremel as the motors and chuck part but think i will use the slitting saw for my X2 clone and have sent emails to a company or 3 to ask if they will ship here ( MAN are there some fine ones available just again not here , OZ) cheers

greenie, rick thank you i was thinking that way myself but i will wish to cut tool steel ( and screwed 3 jewelers blades yesterday finding out what did not work ) :big:

Bob, basically i'm scaling down tools, i have been a avid tool nut for years for various reasons

Knife making and rifle making being a big part of that to the extent i now pretty much rely on Black Powder Rifles as my main part of my income with the odd Bolt Action thrown in
and over the years have hung around old blokes who have made their own tools and been influenced by Popular Mecanics magazine, popular science and The Home Gunsmith magazines and the tools they publish ( i've been scanning these and putting the expired copyright versions/ permitted public usage versions in the download sections)

i am not a engineer, not even a decent mechanic just comfortable with working with the tools i know and trust and wish to scale these down to suit model making. Some of these tools have very small slits similar to collet bands/slots/slits ( what is the name for the slot on a collet?) and this is why the need for small slitting saws.

my long term goal is a RC model i have made myself, very advanced even by many folks here standards and maybe not doable within 10 years, but i'll have a go and go step by step and learn skill by skill along the way

the RC is the easy part the body is relatively easy, the rest ( engine and controls) we'll see as i go, I hope to learn those parts here frankly.

another project is a 1/10th scale fully functional black powder rifle, this will not take 10 years and hope to have a few of these made to promote my real rifles in the USA and EU by the end of next year, global economy permitting.

( mounted in a presentation case etc not intended for use but capable of being used if you have the inclination /streak of madness once i have one made i'll make a video of it and Youtube it etc and give copies of the video to my agent in the US to show his clients as a promotional tool)

again the tooling for these will need to be scaled down and again the need to cut very small slits on tool steel is needed to make this happen, a swiss company that made "so so " quality handguns became very famous ( and increased thier sales but 1800%) by making the worlds smallest operational handguns, i wish to do similar with blackpowder rifles. But purely as a promotional thing, not mass produced. can you imagine the rifling die for a 1.95mm bore? ( 0.0765" cal. :eek: :eek: :eek: )

Again thank you to everyone for thier input , i have catalouges for Australia up the wahzoo but things this thin or specialised are just not listed here and if you do not use the correct term in google etc i get Australian listings that again do not suit, i went to MCS ( thanks Chuck!) cut and paste the heading for thier slitting saws ( micro fine) into google and got a heap of listing that did suit. without this info/ term i was chasing ghosts.

cheers

ozmestore1 on ebay have slitting saws down to .5mm
may be worth an email to see if they go smaller. Have to make an
holder to suit Dremel though.
cheers

G'day Rocker

never got a responce from him ever to be honest i have bought from him in the past good fast service, if pricey

his saws are quoted as 0.5mm but with the tooth offset they measure 0.78 and produce a .80 cut

this is just too big

o did find this when i paste the MCS description into google

http://www.niagaracutter.com/millingcutters/saws.html

and at $10 US Ti Ni coated thats a steal

thanks for the thought but the Ozmestore1 is awful slack at anwsering questions ( like never)

the Niagra site state no order too small and ship anywhere , ya gotta like that

i've sent off a email and if thats ok i'll phone monday and CC 2

as for making a arbour for the things i love that, making bits is almost as good and makin things

even better when they work well!!!

thanks for the idea though eh

cheers mate

Actually the Niagara Cutter plant in Reynoldsville PA that makes
those tools is about 18 miles away from my house.

I have a few friends who work there.
It's small town service and excellet quality tooling!

Rick



 
Rick thank you very much for that

we had a company similar here years ago

prefer to deal with folks like that

some places dont wish to deal with non engineeers or small customers

i like how they word things and i can see a few of the

PDF no. B555 - Straight Tooth Shank-Type Keyseat Cutter* Stocked with Extended Center on Cutting End.

coming to live here too

NO-ONE makes No. 202 & 1/2 or 302 & 1/2 cutters anymore i thought ( weird size woodruff key cutters)

i have been making my own now from endmills for 5 years or so, so the place, if the quality is ok is gold for me

i have asked suttons (Australian toolmakers) to make some but they wont unless i buy 150, an guarentee i buy another 150 within a year HA! so they'll get some orders from a nutcase in OZ if all looks ok

thanks again eh good to know

cheers

jack



 
for those interested in this from Oz

Niagra in the past few weeks have appointed a agent in Australia

http://www.boyartoolco.com.au/

melbourne based but they promise the same service as the US parent outfit
( small orders welcome!!!)

sounds good

cheers
