Einhell HSS Drill Bits
Einhell HSS drill bits are for clean, reliable drilling in steel, aluminium and sheet metal when wood bits or masonry bits will just chew and skate.
If you're drilling trunking brackets, sheet steel, angle, or thin plate, this is the bit you reach for. Einhell metal drill bits are built for cleaner starts and less wandering in metalwork, whether you're topping up a single replacement or buying an einhell drill bit set to keep in the van with your Einhell drills and drivers. If you need more options across the range, see Einhell drill bits and get the right sizes sorted.
What Are Einhell HSS Drill Bits Used For?
- Drilling clean holes through mild steel box section, flat bar, and brackets when you are fixing frames, plant supports, or site-made metalwork.
- Opening out sheet metal on electrical and mechanical installs where a wood bit would snatch, chatter, or leave a ragged hole.
- Working through aluminium, copper, and other softer metals for fabrication, ducting, and workshop jobs where you need a neat finish and accurate sizing.
- Using in an Einhell bench drills setup for steadier, repeated drilling when you are making multiple holes in the same stock.
- Keeping an einhell hss bit set in the van for replacement work, snagging, and quick fixes so you are not trying to force the wrong bit through metal.
Choosing the Right Einhell HSS Drill Bits
Match the bit to the metal and the hole size. That is the bit most lads get wrong.
1. HSS vs Cobalt
If you are mostly drilling mild steel, aluminium, and general site metalwork, standard einhell hss drill bits are the sensible buy. If you are into harder steels, tougher stock, or repeated drilling that runs hot, look at Einhell drill bit sets that include tougher options, or move up to einhell cobalt drill bits.
2. Singles or Sets
If you only keep burning through one or two common sizes, buy replacements and top the box up. If you are fitting out, fabricating, or jumping between jobs, an einhell drill bit set saves time because the right size is there when you need it.
3. Job Material
Do not use metal bits for block or brick and expect them to last. For anchors and fixings into walls, swap over to Einhell masonry drill bits and keep each bit doing the job it was made for.
4. Hand Drill or Bench Drill
If you are working overhead or doing quick site fixes, use the bit in a handheld drill and keep pressure steady. If you are drilling repeated holes in steel stock, a bench drill setup gives you straighter holes, less bit wear, and better control.
Who Uses These on Site?
- Sparkies use Einhell HSS drill bits for metal back boxes, trunking, cable tray supports, and control panel work where a clean hole matters.
- HVAC fitters and plumbers reach for them when drilling brackets, unistrut, duct supports, and light gauge steel without tearing the material up.
- Fabricators and maintenance teams keep an einhell drill bit set handy for workshop repairs, plant guarding, hinges, and general steelwork jobs.
- Site fitters and installers use einhell metal drill bits when assembling handrails, frames, and fixings where the bit needs to cut true instead of skating across the surface.
The Basics: Understanding Einhell HSS Drill Bits
Metal bits look simple, but getting the right type makes the job quicker and saves wrecking the bit. Here is the part that actually matters on site.
1. HSS for General Metal Drilling
HSS stands for high speed steel. In practice, that means a bit suited to routine drilling in mild steel, aluminium, copper, and sheet material without blunting straight away on normal site and workshop jobs.
2. Cobalt for Harder, Hotter Work
Cobalt drill bits are the step up when the material is harder or the drilling is more demanding. They cope better with heat and repeated use, which matters when you are drilling tougher steel or doing a lot of holes back to back.
3. Sharp Point and Steady Speed Matter
A metal bit cuts best when the point bites cleanly and the drill is not screaming flat out. Slower speed, steady pressure, and a proper centre mark usually mean a cleaner hole and less chance of the bit wandering off across the work.
Useful Extras for Einhell HSS Drill Bits
A few sensible add-ons make metal drilling cleaner, quicker, and far less frustrating on site.
1. Cutting Fluid
Use a bit of cutting fluid when you are drilling steel and doing repeated holes. It helps keep heat down, stops the tip cooking itself, and gives the bit a better chance of lasting longer.
2. Centre Punch
This stops the bit skating all over painted or smooth metal before it bites. One quick mark saves wonky holes, scratched finishes, and that irritating start where the bit refuses to stay put.
3. Bit Case or Index Box
Loose metal bits disappear fast in the van. A proper case keeps your sizes in order so you are not wasting ten minutes hunting for a 6mm that should have been back in the box.
Choose the Right Einhell HSS Drill Bits for the Job
Pick the bit by material and how often you drill it.
| Your Job | Category or Type | Key Features |
|---|---|---|
| General drilling in mild steel, aluminium, and sheet metal | Standard Einhell HSS drill bits | Good all-round metal cutting, clean holes, sensible choice for everyday site and workshop work |
| Keeping a spread of common sizes in the van or workshop | Einhell drill bit set | Multiple sizes in one case, quicker size changes, easier to replace worn-out site favourites |
| Repeated drilling in tougher steels or hotter running jobs | Einhell cobalt drill bits | Better heat resistance, stronger on demanding drilling, more suited to harder material |
| Accurate repeated drilling on stock at the bench | HSS bits used in a bench drill | Better control, straighter holes, less wander, ideal for repeated fabrication work |
Common Buying and Usage Mistakes
- Buying one cheap mixed set and using it for everything is where bits get ruined fast. Keep metal bits for metal and use the right masonry or wood bit for the rest.
- Running HSS bits too fast in steel overheats the tip and dulls it early. Back the speed off, use steady pressure, and let the bit cut instead of burn.
- Skipping a centre punch on smooth metal usually means the bit skates and the hole ends up off mark. One quick punch mark sorts the start and saves the finish.
- Forcing a blunt bit through harder steel wastes time and can snap the bit. If the job is tougher material, move up to cobalt rather than bullying the wrong bit.
- Not checking the size spread in a set leaves you short of the sizes you actually use. Make sure the set covers your usual fixings, clearance holes, and pilot work before you buy it.
HSS Drill Bits vs Cobalt Drill Bits vs Masonry Drill Bits
HSS Drill Bits
This is the standard choice for general metal drilling. They are right for mild steel, aluminium, and day to day workshop or site fixing work, but they are not the best shout for harder steels or hammer drilling into brick.
Cobalt Drill Bits
Cobalt bits are better when the material is tougher and the bit is running hotter for longer. If you drill metal occasionally, HSS is usually enough. If you are drilling harder steel often, cobalt earns its keep.
Masonry Drill Bits
Masonry bits are for brick, block, and concrete, not metal. They work with impact and abrasive cutting, so using them on steel gives a poor hole and a pointless fight. Keep them for wall fixings and anchors only.
Maintenance and Care
Clean Swarf Off After Use
Wipe the bit down after drilling, especially if you have used oil or cutting fluid. Leaving swarf and grime on the flutes just encourages rust and makes the box a mess.
Store Them Back in Size Order
Put each bit back in its case or index after the job. That stops chipped tips from knocking together and means you can actually find the right size next time.
Watch for Heat Damage
If a bit has gone blue from heat or stopped cutting cleanly, it has had a hard life. You might get a few more holes out of it, but it is usually time to replace it rather than fight it.
Use the Right Speed
Most metal bit damage comes from overspeeding, not bad luck. Keep revs sensible and pressure steady so the edge keeps cutting instead of rubbing itself blunt.

Einhell HSS Drill Bits FAQs
What's the difference between HSS and cobalt drill bits?
HSS bits are the standard choice for general drilling in mild steel, aluminium, and other everyday metals. Cobalt bits are the tougher option for harder steels and repeated drilling where heat builds up. If your work is mostly routine site metalwork, HSS is usually plenty. If the material is harder and the bit gets worked hard all day, cobalt is the better call.
Are Einhell HSS drill bits suitable for metal?
Yes, that is exactly what they are for. Einhell HSS drill bits are suited to metals like mild steel, aluminium, and sheet material. Use the right speed, keep the bit centred, and do not try to force it through hardened material it was never meant for.
What sizes are in an Einhell HSS drill bit set?
That depends on the set, so always check the size list on the product page before you order. Most sets cover a run of common diameters for pilot holes, clearance holes, and general metal fixing work, but some are more compact while others give you a broader spread for workshop use.
Will these bits work in a normal cordless drill?
Yes, as long as the chuck size matches the shank and the drill has enough control for the job. For lighter steel and site fixes, a cordless drill is fine. For repeated or more accurate drilling, a bench drill will give you straighter results and less strain on the bit.
Do I need cutting fluid when using Einhell metal drill bits?
Not for every quick hole, but it helps a lot on steel and repeated drilling. A bit of cutting fluid keeps heat down, helps the bit cut cleaner, and usually gets you more life out of the set. If you are doing a lot of holes, it is worth it.
Are these better bought as singles or as a set?
If you burn through the same sizes again and again, singles make sense. If your work varies and you need a spread of sizes ready to hand, an einhell drill bit set is the smarter buy because it keeps the common sizes together and ready for the next job.
