Shop for the latest & greatest Coil Master Products from Legion Of Vapers.
Coil Master is the brand most serious coil builders reach for when they want reliable, purpose-built tools that hold up to daily use. Founded with one goal \- making better coils easier and more consistent to build – Coil Master has become one of the most recognised names in the rebuildable vaping space globally. Their range covers everything a builder needs: complete DIY kit sets, standalone coiling jigs, the iconic 521 Mini Tab ohm reader and dry-fire platform, resistance wire, vape bags and storage solutions. Through our own testing, we’ve found that vapers choose Coil Master because the tools are built to a standard that budget alternatives simply don’t match. The coiling jigs produce tighter, more even wraps, and the 521 Tab gives accurate ohm readings that make setting up a build safer and far less guesswork. At Legion Of Vapers, we stock a full range of genuine Coil Master products, sourced through authorised UK distributors.
Coil Master built its reputation on making precision building tools accessible. Before the brand existed, coil builders were improvising with household tools and getting inconsistent results. Coil Master changed that by engineering dedicated, ergonomic tools with tight manufacturing tolerances – the kind of consistency that makes the difference between a build that reads 0.26 ohm and one that reads 0.31 ohm on the same target wrap.
Coil Master remains the benchmark for vape building tool quality because they focus exclusively on getting this one thing right.
Coil Master DIY Kits
The DIY kits are Coil Master’s flagship offering and the most practical entry point for anyone moving into coil building. Three versions exist – the Mini, Mini V2 and V3 – each packaged in a hard carry case with a curated set of tools. The V3 is the most complete, including a coiling jig, ceramic tweezers, scissors, screwdrivers and an ohm reader. The Mini and Mini V2 are more compact, suited to vapers who build occasionally or travel with their kit.
If you’re starting out, the DIY Kit V3 gives you everything in one purchase. If you already have some tools and just need a portable top-up kit, the Mini is the better call.
Coil Master 521 Mini Tab
The 521 Mini Tab is one of the most useful single tools in a builder’s kit. It powers from a single 18650 battery and functions as both an ohm reader and a dry-fire platform – letting you fire your coils before wicking to check for even heating and hot spots. It reads down to 0.1 ohm and includes reverse battery protection and short-circuit protection as standard.
We use the 521 Tab as the first step on every new build. The dry-fire function shows up hot spots in seconds, long before cotton goes in, which saves wasted wicks and gives you a cleaner starting point. If you only buy one standalone Coil Master tool, this is it.
Coil Master Coiling Kits and Jigs
The standalone coiling kit is built for vapers who want consistent wraps without the guesswork. Multiple mandrel sizes let you hit specific internal diameters reliably, which matters when you’re chasing a target resistance. We’ve found it produces noticeably neater wraps than improvised alternatives, and the jig holds wire firmly enough to prevent slippage mid-wrap – a small thing that makes a real difference when you’re working with finer gauge wire.
Coil Master Wire
Coil Master produces resistance wire in a range of types and gauges. Options include standard Kanthal A1 (the most common starting point for new builders), as well as Ni80 and SS316L for vapers using temperature control mode. Wire is sold on spools and is compatible with any RDA, RTA or RDTA.
Kanthal is the most forgiving for beginners – it holds its shape well and is straightforward to work with at most coil diameters.
Coil Master Accessories, Bags and Storage
Beyond the core tools, Coil Master produces the Kbag and Vape Bag storage solutions, designed to keep your gear organised and protected. The Kbag is a zip-up pouch suited for carrying tools, cotton, wire and spare parts together. The Vape Bag is a larger carry option for protecting full setups when travelling. Both use durable materials and are worth picking up if you’re moving from building at a desk to building on the go.

We’ve stocked and personally used Coil Master tools for years. The reason they stay in our range is simple: they do what they say, build after build, without tools bending, slipping or giving inaccurate readings. For vapers moving into rebuildables, having tools that don’t let you down removes one variable from a process that already has plenty of them.
Coil Master is the brand we recommend to anyone stepping into rebuilding for the first time, and the one most of our experienced customers already have in their kit bag.
The right Coil Master product depends on where you are in your building journey and what you already have. Your experience level, how often you build and what atomisers you use will all point you toward the right product.
Start with the DIY Kit V3. It includes every tool you need for your first build and avoids the mistake of buying individual pieces one at a time and realising you’re still missing something. Pair it with a beginner-friendly RDA or RTA and you have everything in one purchase. Our guide to building vape coils walks through the process from first wrap to first vape.
The DIY Kit Mini or Mini V2 covers the essentials in a compact case. If you already have a coiling jig and just need a carry kit for travelling or topping up, these give you the core tools without duplicating what you own. The Mini V2 also updated the screwdriver to double as a coil winder, which is a handy small upgrade.
The 521 Mini Tab is the answer. It’s the most practical standalone tool Coil Master makes and pulls double duty as a dry-fire platform. If you’re already building but relying on firing coils directly on your mod to check for hot spots, the 521 Tab is a safer and more accurate way to do it. See our guide to ohms law if you want to understand what you’re reading.
If you’re looking at Coil Master to cut down on replacement coil costs, this is the right call. A 5-pack of sub-ohm replacement coils costs roughly £5-10 and typically lasts 1-2 weeks. A Coil Master kit plus a small spool of Kanthal and some cotton is a one-time cost that runs for months. Our article on whether vaping can save you money covers the maths in more detail.
Pick up Coil Master’s SS316L or Ni80 wire. Both work in temperature control mode on a regulated mod, which gives you a more consistent vape across a session once you dial in your target temperature. Kanthal does not work in TC mode – it’s watts only. If you’re not sure which setup you’re running, our guide to temperature control vaping explains the difference clearly.
Every Coil Master product we sell is sourced through authorised UK distributors only. Given how many generic building tool kits exist that use the Coil Master name or closely imitate their product range, this matters. You’re getting the real thing, with the correct safety certifications and materials – not a lookalike that reads ohms inaccurately or uses heat-sensitive plastic where it shouldn’t.
We keep our Coil Master pricing competitive. Check our accessories and vape tools sections for any current multi-buy options or bundle deals. If you’re building out a full kit from scratch, buying through us in one order is usually the most cost-effective route.
We dispatch orders fast from our UK warehouse. Orders over the free delivery threshold ship without extra charge, and most customers receive their order within 1-3 working days. No waiting weeks for international shipping on tools you need this weekend.
Our team are active vapers who use rebuilding gear regularly, including Coil Master products. If you’re not sure which kit version suits your setup, or you want to know whether a specific wire gauge will hit your target resistance on your RDA, we can give you a straight answer based on experience – not a script. Get in touch via our contact page and we’ll point you in the right direction.
Explore our answers to some frequently asked questions.
The V3 is the most comprehensive, including the widest selection of tools in a full-size case. The Mini and Mini V2 are more compact, suited to vapers who build occasionally or want a portable travel kit. The Mini V2 updated the case material and redesigned the screwdriver to double as a coil winder.
Yes. It includes reverse battery protection and short-circuit protection as standard, and fires coils down to 0.1 ohm. Always check your coil resistance before firing and stay within safe ohm ranges for your wire type. Our guide to ohms law covers what to look out for.
Kanthal A1 is the most forgiving starting point. It holds its shape after wrapping, is easy to work with, and is compatible with standard wattage mode on any regulated mod. Ni80 and SS316L are worth exploring once you’re comfortable with the basics, particularly if you want to use temperature control mode.
A coiling jig, ceramic-tip tweezers, scissors, a small flathead screwdriver and an ohm reader covers everything for most builds. The DIY Kit V3 includes all of these. Our how to build vape coils guide walks through each step if you want to understand the process before buying.
The tools are universal – a coiling jig works regardless of which rebuildable you’re building for. Wire compatibility depends on your atomiser’s coil deck and post hole size, but Coil Master offers enough wire options to cover the vast majority of setups. See our RDA, RTA and RDTA guide if you need help choosing an atomiser to pair with your new tools.
