What Are Milwaukee SHOCKWAVE HSS Drill Bits Used For?
- Drilling clean holes through steel trunking, cable tray and electrical boxes where a bit that starts without skating saves time and bad language.
- Working through sheet metal, angle and mild steel on first fix and fab jobs where standard bits often overheat or lose their edge too quickly.
- Boring into stainless steel fittings and tougher metals when you use the right speed and cutting fluid instead of trying to force the bit through dry.
- Keeping impact drivers useful for light drilling tasks on site when you need an impact-rated bit that can cope with the tool you have in your hand.
- Replacing worn van-stock metal bits with sizes that hold up better for repeated pilot holes, clearance holes and general fixing work.
Choosing the Right Milwaukee SHOCKWAVE HSS Drill Bits
Sorting the right bit is simple: match it to the metal, the hole size and the tool in your hand. Do not just grab the nearest one and lean on it.
1. Job Material Comes First
If you are mostly drilling mild steel, your standard HSS sizes will cover a lot of daily work. If stainless is turning up regularly, slow the tool down, use cutting fluid and do not expect any bit to survive being run flat out and dry.
2. Buy the Sizes You Actually Burn Through
If you are always drilling pilot holes for self-drillers or opening out for bolts, stock extra of those common sizes instead of one big set that sits in the van untouched. The bits you use every day are the ones worth doubling up on.
3. Impact Driver or Drill
If you are using an impact driver for quick access work, these impact-rated bits make more sense than standard jobber bits. If you are drilling larger holes all day in thicker metal, a proper drill with controlled speed is still the better shout.
4. Single Bits vs Sets
If you know exactly what sizes your trade uses, buy singles or trade packs and keep the van topped up. If you cover mixed snagging and maintenance jobs, a set gives you enough range without hunting round for odd sizes mid-job.
Who Uses These on Site?
- Sparkies use these for drilling steel back boxes, trays, trunking and enclosures, especially when they are moving quickly between pilot holes and fixings with an impact driver.
- HVAC and ducting fitters swear by them for sheet metal and bracket work where a bit that does not wander all over the panel makes set-out cleaner.
- Plumbers and mechanical installers reach for them when drilling brackets, clips and plant room steel, particularly on refurb jobs with mixed materials.
- Fabricators and maintenance teams keep them close for everyday metal drilling where snapped bits and blunt tips slow the whole job down.
- Site fitters and van-based trades like them as a tough grab-and-go option for quick metal holes without carrying a separate drill for every small task.
The Basics: Understanding HSS Drill Bits
Metal bits are not complicated, but getting decent life out of them comes down to tip design, speed and pressure. Here is what matters on site.
1. HSS for Metal Drilling
HSS stands for high speed steel. In plain terms, it is the standard type of bit for drilling metal, giving you the hardness needed for steel, aluminium and similar materials without chipping away like a masonry bit would.
2. The Tip Has to Start Clean
A good metal bit needs to bite early instead of skating across the surface. That means neater holes, less marking out damage and less chance of the bit grabbing when you are drilling awkward positions.
3. Speed Matters More Than Force
Most burnt bits are not worn out, they have been overheated. Run the bit too fast in steel and you lose the edge. A steadier speed with firm pressure usually cuts faster and leaves the bit usable for the next hole.
Accessories That Make Metal Drilling Easier
A couple of simple extras save broken bits, poor holes and wasted trips back to the van.
1. Cutting Fluid
If you are drilling steel or stainless dry, you are cooking the bit and making the job harder than it needs to be. A bit of cutting fluid keeps heat down, helps the bit clear swarf and gives you noticeably better life.
2. Centre Punch
This stops the bit wandering all over painted steel or smooth sheet before it bites. One quick punch mark saves ugly starts, scratched finishes and holes ending up a few millimetres out.
3. Chuck Adaptors
If your setup changes between drill and impact driver, the right chuck adaptor keeps the job moving. It is a lot better than bodging the wrong shank into the wrong tool and wondering why the bit runs out.
Choose the Right Milwaukee SHOCKWAVE HSS Drill Bits for the Job
Pick by material, access and how often you drill that size.
| Your Job | Category or Type | Key Features |
|---|---|---|
| Drilling trunking, tray and electrical boxes | Small diameter HSS bits | Clean starting point, good control in thin steel, ideal for pilot and fixing holes |
| General fab work in mild steel section | Common size HSS singles or packs | Stock the sizes you wear out most, easier to replace, better van stock management |
| Mixed snagging and maintenance jobs | HSS drill bit set | Wide size spread, useful when you do not know what fixings or hole sizes the day will throw at you |
| Light metal drilling with an impact driver | Impact rated SHOCKWAVE HSS bits | Built to cope with hex-shank use, handy for quick access work and smaller holes |
| Drilling stainless steel fittings | HSS bits used at lower speed | Needs controlled drilling, steady feed and cutting fluid to stop overheating and edge loss |
Common Buying and Usage Mistakes
- Running metal bits too fast is the big one. It overheats the tip, turns it blue and kills the edge, so back the speed off and let the bit cut.
- Using one bit for every material usually ends badly. If you are moving from timber to masonry to steel with the same bit type in mind, you are choosing the wrong kit for the job.
- Buying only a mixed set and no spare common sizes sounds tidy but slows you down later. The sizes you use every day will disappear or wear first, so keep extras of those.
- Skipping a punch mark on smooth metal makes the bit skate and leaves ugly holes. Mark it properly first if the finish or position matters.
- Forcing bits through stainless dry will blunt them fast. Use cutting fluid, lower speed and steady pressure or you will ruin good bits for no reason.
HSS Bits vs Cobalt Bits vs Holesaws
HSS Bits
These are your everyday metal drilling choice for pilot holes, fixings and general steel work. They are the practical option for most trades, especially where you need a wide spread of sizes and regular replacements.
Cobalt Bits
Cobalt bits make more sense if you are regularly on harder metals and stainless. They cost more, but they are worth it when standard HSS is getting cooked too often on tougher material.
Holesaws
If you need larger diameter holes in metal, stop trying to step up with standard bits and use a holesaw. It is cleaner, quicker and far less punishing on both the tool and the operator.
Maintenance and Care
Clear Swarf After Use
Wipe the bits down after drilling metal, especially if you have used cutting fluid. Leaving swarf and residue on them in the case is a good way to invite rust and blunt edges.
Store Sizes Properly
Chuck loose bits in the bottom of the box and they will knock into each other, chip and go missing. Keep them in the indexed case or a proper bit holder so you can grab the right size quickly.
Watch for Heat Damage
If the tip has gone blue or the bit is squealing through steel instead of cutting, it has likely been overheated. Replace it or relegate it to lighter work rather than fighting it all day.
Use Lubrication on Tougher Metals
A drop of cutting fluid on stainless and thicker steel is not fussing, it is basic bit care. It keeps temperatures down and gives you more life out of every size.
Replace Worn Common Sizes Early
Do not wait until the bit is completely dead. If your usual pilot sizes are dull, replace them before they start chewing holes oversized and slowing every fixing job down.

Milwaukee SHOCKWAVE HSS Drill Bits FAQs
Are Milwaukee Shockwave HSS drill bits impact-rated?
Yes. These are designed for use in impact drivers, which is the whole point of the SHOCKWAVE setup. That said, impact-rated does not mean every job should be done with an impact driver. For repeated larger holes in thicker steel, a drill with proper speed control is still the smarter option.
What is the benefit of the Thunderbolt web design on these drill bits?
It gives the bit a thicker core, which helps with strength and reduces the chance of snapping under load. On site, that means better durability when you are drilling awkward angles, using compact tools or working through tougher metal where thin bits often fail first.
Can these bits be used for drilling through stainless steel?
Yes, they can, but be sensible about it. Stainless punishes bits if you run too fast or drill dry. Use a slower speed, steady pressure and cutting fluid, and they will do the job properly. Abuse them and you will blunt them quickly, same as any metal bit.
Will these bits wander on smooth metal before they bite?
No more than a decent metal bit should, and they start cleaner than cheap general purpose bits. On painted or polished surfaces, though, a quick centre punch is still the right move if you want the hole exactly where you marked it.
Are they worth buying as singles or should I just get a set?
If you know the sizes you burn through every week, buy singles or packs of those and keep extras. If your work changes day to day, a set makes more sense. Most trades end up doing both, with a set for range and spare common sizes for the stuff that always gets used.
Do these actually last on site, or are they just another bit set that gets binned fast?
They hold up well if you use them properly. The usual killers are heat, too much speed and trying to force the wrong size through the wrong material. Treat them like metal bits rather than disposable fixings, and they will last a lot better than bargain bits.
