Evolution Magnetic Drills
Evolution mag drill kit is for clean, accurate holes in steel when a hand drill just will not hold line or power through thicker sections.
If you are drilling RSJs, steel plate, box section or site-fabricated frames, an Evolution Tools magnetic drill saves time and keeps cuts square. These are the machines fitters, steel erectors and fabrication teams reach for when twist bits start wandering and step drills get slow. Match the drill to your cutter size, stroke and steel thickness, then get the right setup for the work.
What Are Evolution Mag Drills Used For?
- Drilling clean structural holes through RSJs, channels and steel plate on site, where a standard pistol drill would snatch, wander or leave you fighting for accuracy.
- Cutting larger diameter holes for bolted connections, bracket fixing and steelwork installation, especially when annular cutters make more sense than burning out full holes with twist bits.
- Working on fabrication benches and in workshop bays where repeatable, square holes matter for handrails, frames, plant mounting and general metalwork prep.
- Handling retrofit and maintenance jobs on existing steel, such as adding cable tray supports, pipe brackets or machinery fixings without dragging bigger workshop kit onto site.
- Drilling overhead or vertical steel faces more safely when the magnet is properly seated and strapped, which is exactly why site teams keep one for awkward steelwork jobs.
Choosing the Right Evolution Mag Drill
Sorting the right one is simple: match it to the steel, the hole size and the access, not just the price tag.
1. Hole Size First
If you are mainly cutting common fixing holes and mid-size structural holes, a standard-capacity model will do the job. If you are regularly opening out larger holes in plate or beam, buy for the biggest cutter you actually use, not the one-off job you might never see again.
2. Check the Stroke and Reach
If you are drilling through thicker section steel or using longer cutters, you need enough travel to finish the hole properly. Too little stroke and you will be faffing with setup instead of cutting, especially on deeper flange and plate work.
3. Think About Site Access
If the work is in cramped plant rooms, tight steel frames or awkward vertical positions, go compact where you can. A bigger mag drill is fine on open bench work, but it can be a nuisance when you are trying to get onto steel tucked behind services or cladding.
4. Buy the Right Cutter Setup at the Same Time
Do not order the drill and forget the working kit. Pair it with the proper Evolution Broaching Cutters for the diameters and depths you actually need, otherwise the machine turns up and the job still waits.
Who Uses These on Site?
- Steel erectors use Evolution mag drills for bolting up structural sections, because they need straight, repeatable holes in beams and columns without wrestling a hand drill all day.
- Metal fabricators keep them on the bench for brackets, frames and plate work, where annular cutters speed the job up and leave a cleaner finish than forcing big twist bits through.
- Mechanical fitters reach for them when mounting plant, supports and base plates, especially on shutdown work where there is no time for sloppy holes or rework.
- Maintenance teams use them for retrofit steel drilling in factories and plant rooms, and usually keep the cutter set close by so they can move from one hole size to the next without faff.
- Site engineers and installation crews also use them for controlled drilling into existing steelwork, particularly when access is tight and a pillar drill is not an option.
The Basics: Understanding Magnetic Drills
A mag drill is basically a portable drilling setup for steel. The magnet locks the machine to the workpiece so you get a straighter, cleaner hole with far less fighting than you get from a hand drill.
1. The Magnet Is What Makes It Work
The base energises and grips the steel so the drill stays planted while cutting. On site, that means more accurate holes in beams, plate and section steel, but only if the material is thick enough, clean enough and flat enough for the magnet to hold properly.
2. Annular Cutters Remove Less Steel
Most magnetic drills use broaching or annular cutters, which cut the outer edge of the hole rather than chewing out the whole diameter like a large twist bit. That is why they cut faster, run cleaner and make big holes in steel far more manageable.
3. Setup Matters as Much as Power
A properly seated magnet, the right cutter, cutting fluid and a safety strap are what make these drills work well on site. Rush the setup and you risk poor cutter life, rough holes or a machine that is not held as securely as it should be.
Mag Drill Accessories That Save Time on Steel
Get the support kit sorted with the drill so you are not stuck on site with the wrong cutter or a worn consumable.
1. Broaching Cutters
This is the obvious one, but it is also the one people miss. Get the right diameters and cutter depth for the steelwork you are drilling, otherwise you will end up opening holes the hard way or heading back to the van empty handed.
2. Pilot Pins
Pilot pins help centre the cut and assist slug ejection, which saves a lot of grief when you are drilling repeated holes in structural steel. Run a worn or wrong pin and the cut gets messier and less reliable.
3. Cutting Fluid
Do not skip it. Proper cutting fluid keeps heat down, helps the cutter last longer and leaves a cleaner finish, which matters when you are pushing through thicker steel all day.
4. Carry and Storage Gear
A magnetic drill is not something you want bouncing around loose in the van. Evolution Tool Bags & Totes help keep cutters, pins and the drill together so you are not hunting for bits when the steelwork is ready.
Choose the Right Evolution Mag Drill for the Job
Use this quick guide to match the drill to the steelwork you are actually tackling.
| Your Job | Category or Type | Key Features |
|---|---|---|
| General fabrication and bracket work in the workshop | Standard magnetic drill | Good all-round cutter capacity, stable base, enough stroke for routine plate and section drilling |
| Structural steel fixing holes on beams and columns | Site mag drill | Strong magnetic hold, annular cutter compatibility, practical carry weight and safety strap provision |
| Tight access steel in plant rooms or framed installations | Compact magnetic drill | Lower profile body, easier positioning, suited to awkward spots where larger units are a pain |
| Larger diameter holes in thicker plate | Higher capacity mag drill | Bigger cutter range, longer stroke, better suited to repeated heavy drilling work |
Common Buying and Usage Mistakes
- Buying for motor size alone and ignoring cutter capacity is a common mistake. The fix is simple. Check the maximum annular cutter size and stroke first, because that is what decides whether the drill actually suits your steelwork.
- Trying to run a mag drill on steel that is too thin, dirty or uneven causes poor magnetic hold. Clean the contact area and make sure the material meets the drill's holding requirements before you start.
- Using the wrong cutter or a blunt one slows the cut and hammers the machine. Match the shank and size properly, use cutting fluid and replace worn cutters before they ruin the job.
- Skipping the safety strap because the magnet feels solid is asking for trouble. If power drops or the surface is not ideal, that strap is what stops the drill becoming a falling lump of steel.
- Treating it like a hand drill and forcing the feed will shorten cutter life fast. Let the cutter work at a steady rate and keep the setup square, especially on thicker material.
Mag Drills vs Hand Drills vs Pillar Drills
Mag Drills
This is the pick for portable, accurate steel drilling on site. You get a fixed position on the workpiece, cleaner large holes with annular cutters and far less wrestling than with a hand drill.
Hand Drills
Fine for small holes and quick jobs, but once diameters go up or the steel gets thicker, they are slower, harder to control and more likely to wander. Good backup, not the right answer for repeated structural drilling.
Pillar Drills
Best in the workshop where the material can come to the machine and repeat accuracy matters. The downside is obvious on site. You are not dragging a pillar drill onto a beam line or into a plant room.
Maintenance and Care
Keep the Magnet Base Clean
Wipe swarf, oil and rust scale off the base after use. A dirty magnet face means weaker hold, and that is not something you want to find out halfway through a cut.
Look After the Cutters
Store cutters dry, keep them separate so the edges do not knock together and replace them when they stop cutting cleanly. Blunt cutters waste time and put extra strain on the drill.
Use Cutting Fluid Properly
Do not run annular cutters dry unless the setup specifically allows it. Proper lubrication reduces heat, helps finish quality and keeps consumable costs from creeping up.
Check Leads, Handles and Strap Points
Before each job, inspect the cable, feed handles and safety strap attachment points. If anything is loose or damaged, sort it before the drill goes onto steel.
Store It So It Is Ready for Site
Keep the drill, pins, cutters and accessories together in one place. That stops damage in the van and saves turning up to a steel job with half the kit missing.

Evolution Mag Drill FAQs
What is an evolution mag drill used for?
An evolution mag drill is used for drilling accurate holes in steel plate, beams, box section and other ferrous metal where a normal hand drill is slower and harder to control. It is the right bit of kit for structural steel, fabrication, plant installation and retrofit fixing work.
What thickness of steel do Evolution mag drills need to hold?
They need enough clean ferrous steel under the magnet for the base to grip properly. The exact minimum thickness depends on the model, but the rule on site is simple. Do not trust a mag drill on thin, painted, rusty or uneven steel without checking the spec and always use the safety strap.
What cutters fit Evolution magnetic drills?
That depends on the shank and holder the drill is built for, so always match the cutter to the machine rather than guessing by diameter alone. The safe move is to use cutters listed for the drill, especially when you are buying replacement Evolution Broaching Cutters.
What's the maximum hole size an Evolution mag drill can cut?
The maximum hole size depends on the individual machine and the cutter system it accepts. Some are aimed at routine fixing and fabrication holes, while larger-capacity units are built for bigger annular cutters. Check the stated cutter capacity before you buy, because that is the figure that matters.
Do Evolution mag drills have a safety strap?
Yes, magnetic drills are typically supplied with or designed to be used with a safety strap, and you should treat that as non-negotiable on site. Even with a solid magnetic hold, the strap is there to back the machine up if power is lost or the contact surface is not perfect.
