All are tungsten or Silicon carbide these days. Tips for steel, stainless steel, aluminium etc are all different these days although you can get some general purpose tips. Forget dremels. Decide on a supplier, Iscar, Sandvik, Seco they are not cheap but it is easy to ruin a job halfway through.</span></div><div class="yiv6388169323MsoNormal" id="yui_3_16_0_1_1444763584944_5613"><span style="font-size:11.0pt;" id="yui_3_16_0_1_1444763584944_5612">You will also need a range of measuring equipment, set of micrometers 0-150mm, Telescopic gauges, dial indicators, etc. not to mention drills and taps. Also get a copy of machinery’s handbook.</span></div><div class="yiv6388169323MsoNormal" id="yui_3_16_0_1_1444763584944_5614"><span style="font-size:11.0pt;">To grind high speed steel (HSS) tooling you need to read a few books or do a course at tech. Book in for a machining class and you can do a lot of homers there without having to buy tools. Next thing you need is then a milling machine.
