Mezgike's miniatures are awesome, full of personality and their long videos are like learning while watching a relaxing, ASMR movie.

High speed steel uses

HSS bits are hardwearing and heat resistant. The large concentrations of chrome and nickel in stainless steel ensure that HSS bits are super strong and durable. HSS drill bits are capable of safely drilling through hardwood, some metals and plastic. They’re safe to operate at high speeds (RPM) and provide long-lasting performance – as long as they are maintained.

Cobalt bits are a combination of steel (or another alloy) mixed with a small percentage of cobalt, typically between 5 – 7%. Cobalt has a melting point of 1495°C and a boiling point of 2927°C, which makes it perfect for use at high temperatures. By combining a small amount of cobalt with another alloy, the results are incredible.

The Mezgob miniature is one of the most true-to-form representations of the dakka-loving, git-smashing, beakie-krumpin' greenskin of the grim dark future. Mez completely captures the classically-comedic nature of these beloved Orks, from the gunner-runt to the ciggy of command. Printing, assembling and painting this miniature was an absolute pleasure, and I cannot wait to see what new releases are headed our way. WAAAGGH!!!

The cutting edge on a good quality cobalt bit should last for longer than a standard HSS bit. Like other HSS bits, they are corrosion-resistant, which means they should retain their condition in all storage and usage conditions they’re likely to experience. However, cobalt can be brittle. If your cobalt drill bits aren’t cared for properly or are dropped, they can break – which can prove costly.

The strength of cobalt means that drill bits are better suited to the tough challenge of cutting through steel. Cobalt bits aren’t suitable for general applications. For less intensive operations, like drilling through wood, plastic or light metals, an HSS drill bit is perfect.

Sturdy, hardwearing and robust, modern metal drill bits can cut through the toughest materials with no trouble. When it comes to drilling, selecting the right tool for the job is crucial. In this article we describe the difference between High-Speed Steel (HSS) and cobalt drill bits, their strengths and weaknesses, and when you should use them.

I've backed many Patreons before but Mezgike's is by far my favorite. Not only do I get awesome modular miniatures with heaps of wicked details, but a very in-depth, relaxed and chilled painting video which is totally my pace. Definitely worth the investment!

What is high speed steel made of

They are most often used to cut through hardened and abrasive materials. Cobalt bits are able to cut through the most hardened metals, including bronze, cast iron, stainless steel and titanium. They are also able to cut through weld seams.

Over time, HSS drill bits can become blunt and need to be sharpened, which demands specialist tools that aren’t always available. If you’re using HSS drill bits for long periods or at high RPMs, you may need to use cutting fluid to keep the bit cool.

It’s crucial for the safety of your tools and yourself that you use the right bit for the job. You will find cobalt drill bits stocked alongside other popular choices, including titanium coated, titanium nitride and tungsten carbide bits. Each of these has its strengths and weaknesses which you should be aware of before buying.

Imperiul gitz is a new klan of orcs who reckon they're fooling everyone by wearing disguises made to look like power armour. The bulk of this faction are made up of 'mareen boyz' which is exactly how it sounds; boyz dressed as humie marines. They've got trash cans over their torsos, purity sealz made of rubbish, corrugated iron and rusted metal bolted together into the shape of shoulderpads, and powerpacks that do absolutely nothing except look the part. More is on the way for this new warband.

HSSmeaning in construction

Cobalt drill bits are incredibly strong. They can be operated at much higher speeds than a standard HSS drill bit. The ability to withstand heat means that cobalt bits perform for long periods without cooling or the need for cutting fluid.

People need to get their hands on Mezgob ASAP! It's hands down the most fun I have had painting a mini yet. Super detailed, and every little piece of it has a story. Printing was easy, all the parts came pre-supported, and the whole assembly was super well thought-out! Normally when I'm done with a model, I'm also really done mentally - but I was almost sad when i finished this guy. felt like printing another!

Rarely do you find an artist as talented as Mezgike. Not only does he create stunning models, he also shows you how to paint them in his unique, and varying style. The production quality of his videos are top notch, with tons of fun and unique modelling techniques to learn. Then there's his soothing and calming Aussie voice guiding you trough each video, which is a plus.

These are the green skins you've been waiting for. Get em into your army quick smart, so they can start getting stuck in. More coming every month!

HSS and cobalt drills need to be cared for and maintained to ensure they deliver consistent performance. Even the hardest wearing materials can become blunted or dulled after a period of hard work. Using the correct drilling technique improves the lifespan of any drill bit.
