Sealey Drill Bits
Sealey drill bits cover the everyday holes that keep jobs moving, from timber and steel to block and brick without wasting time on poor fit or blunt edges.
If you're forever hitting mixed materials on snagging, installs or general site work, a decent set matters more than most lads realise. Sealey drill bits give you practical options in HSS drill bits, masonry drill bits and cobalt drill bits, whether you need a single replacement or a full drill bit set. For broader Drill Bits ranges, this is the part of the shelf worth checking when you want straightforward bits that earn their keep. Pick the right type for the material, keep a few spares in the van, and get sorted.
What Are Sealey Drill Bits Used For?
- Drilling steel trunking, brackets and plate on maintenance and install jobs is where HSS drill bits earn their keep, giving you clean holes without chewing themselves up straight away.
- Fixing into block, brick and older masonry on first fix or refurb work is what masonry drill bits are built for, especially when you are putting up clips, conduit, battens or light fixings.
- Working through tougher metals like stainless or harder stock in workshops and plant rooms is where cobalt drill bits make sense, because standard bits can dull fast and start wandering.
- Keeping a drill bit set in the van saves wasting half the morning hunting odd sizes when the job changes from pilot holes in timber to clearance holes in sheet or anchors into masonry.
- Repair work, site snagging and general fabrication all go smoother when you have Sealey drill bits to hand, because mixed-material jobs rarely wait while you go back for the right bit.
Choosing the Right Sealey Drill Bits
Sorting the right bit is simple: match it to the material, not whatever happens to be loose in the bottom of the case.
1. HSS for General Metalwork
If you are drilling mild steel, sheet metal, plastic or timber now and then, HSS drill bits are the sensible all-rounder. If most of your work is standard install and maintenance, this is where to start.
2. Cobalt for Harder Metals
If you are into stainless, tougher steels or repeated workshop drilling, go straight to cobalt drill bits. They cost more, but they hold up better where ordinary HSS bits lose their edge and start cooking.
3. Masonry Bits for Brick and Block
Do not try forcing a metal bit through masonry just because it is in your pocket. If the job is plugs, anchors or fixings into brick, block or mortar, use proper masonry drill bits and let the drill do the work.
4. Singles or a Full Set
If you only ever burn through one or two common sizes, buy singles and keep extras. If your work changes day to day, a drill bit set is the better shout because you are covered when the drawing suddenly calls for a different fixing.
Who Uses These Drill Bits?
- Sparkies use them for cable tray, back boxes, trunking and fixing runs, usually keeping an HSS set close by for quick holes in metal cases and brackets.
- Plumbers and heating engineers reach for masonry drill bits when they are clipping pipework to block and brick, then swap to metal bits for plant room brackets and cylinders.
- Fabricators and workshop fitters swear by cobalt drill bits for harder metals where cheaper bits blunt off and burn before the hole is finished.
- Maintenance teams keep a mixed drill bit set in the van because call-out work can mean timber, steel and masonry all before lunch.
- Anyone running Sealey Magnetic Drills will want the right cutting and drilling kit nearby for accurate holes in steel on site or in the workshop.
Sealey Drill Bit Accessories That Save Time on Site
A few simple add-ons stop lost time, poor drilling and repeat trips back to the van.
1. Sealey Drill & Screwdriver Bit Holders
A decent holder keeps your most-used bits where you can actually find them. Keep Sealey Drill & Screwdriver Bit Holders in the case and you are not rummaging about for the 6mm you just had in your hand.
2. Screwdriver Bits
Most fixing jobs do not stop at the hole. Keep Sealey Screwdriver Bits alongside your drill bits so you can drill, plug and drive without swapping out half your kit bag.
3. Cutting and Prep Accessories
Sometimes the hole is only part of the job and you still need to trim, clean or prep the material. Having Sealey Angle Grinder Discs & Accessories nearby saves dragging out another setup later.
Choose the Right Sealey Drill Bits for the Job
Use this quick guide to avoid wrecking bits on the wrong material.
| Your Job | Bit Type | Key Features |
|---|---|---|
| Drilling mild steel brackets and sheet | HSS drill bits | Good general-purpose cutting, clean holes, sensible for everyday install work |
| Drilling stainless or tougher metals | Cobalt drill bits | Better heat resistance, holds an edge longer, less chance of blunting mid-job |
| Fixing into brick and block | Masonry drill bits | Tungsten carbide tip, built for hammer drilling, suited to plugs and anchors |
| Van stock for mixed call-out work | Drill bit set | Range of common sizes, quicker to grab, keeps you covered when the job changes |
| Replacing one worn common size | Single drill bit | Cheaper than replacing the whole case, handy for the sizes you burn through most |
Common Buying and Usage Mistakes
- Buying one mixed set and expecting it to handle every material usually ends with blunt bits and rough holes. Check whether you actually need HSS, cobalt or masonry bits for the work you do most.
- Using HSS drill bits in brick or block is a quick way to waste time and wreck the cutting edge. Use proper masonry drill bits when the job is fixings into hard walls.
- Pushing too hard and drilling too fast overheats metal bits and takes the edge off them early. Let the bit cut at a sensible speed and back off now and then to clear swarf.
- Ignoring pilot sizes on larger holes often makes the bit wander and leaves a messy finish. Start small where needed, especially on metal, then step up to the final diameter.
- Leaving loose bits rolling around the van knocks the tips about and means you can never find the size you want. Keep them in a case or holder and replace worn favourites before they hold the job up.
HSS Drill Bits vs Cobalt Drill Bits vs Masonry Drill Bits
HSS Drill Bits
These are the everyday choice for general metal, plastic and light timber jobs. They are the practical pick for van stock and regular install work, but they are not the one for hard masonry or repeated stainless drilling.
Cobalt Drill Bits
Cobalt bits suit tougher metals and harder drilling where heat builds up fast. If you are often into stainless, they are worth the extra spend, but they are overkill if all you ever drill is basic sheet and bracketry.
Masonry Drill Bits
These are made for brick, block, mortar and concrete-type materials with the right drill setting behind them. They are useless for clean metalwork, but for wall fixings and site install work they are the right tool without argument.
Maintenance and Care
Clear Swarf and Dust After Use
Wipe metal filings and masonry dust off before the bits go back in the case. Leaving grit on them just wears the case out and makes the next size harder to grab.
Keep Cutting Edges Protected
Do not leave bits loose in a drawer with fixings and blades. Tips get chipped, cutting edges knock together and the bit that looks fine ends up drilling badly.
Use Sensible Speed on Metal
Too much speed builds heat and kills edges fast, especially on smaller bits. Slow it down, use steady pressure and use cutting fluid where the material calls for it.
Replace Worn Common Sizes Early
If your 5mm or 6mm is burnt, chipped or no longer cutting true, swap it out before it slows every fixing down. The most-used sizes are the ones worth keeping spare.
Store Sets Dry
A damp van floor is no place for drill bits. Keep the case dry and shut properly so you are not dealing with surface rust and seized hinges when you need one in a hurry.

Sealey Drill Bits FAQs
What drill bits does Sealey make?
Sealey covers the common site and workshop types you actually use, including HSS drill bits for metal, masonry drill bits for brick and block, and cobalt drill bits for tougher metals. You will also find drill bit set options if you want a case of mixed sizes rather than buying singles.
What is the difference between HSS and cobalt drill bits?
HSS is your general-use metal drilling bit and is fine for most mild steel and everyday work. Cobalt drill bits are better when heat builds up or the material is tougher, so they are the smarter buy for stainless and repeated harder drilling.
What drill bits are needed for masonry?
Use masonry drill bits for brick, block, mortar and similar materials. They have the right tip for hammer drilling and will get the hole done properly, unlike HSS bits which will struggle, overheat and blunt off.
Are Sealey drill bits any good for everyday site work?
Yes, for general install, maintenance and workshop jobs they are a sensible buy. The main thing is choosing the correct type for the material, because even a decent bit will have a hard time if you ask it to do the wrong job.
Should I buy a drill bit set or single bits?
If your jobs change all the time, buy a drill bit set so you are covered for common sizes. If you constantly wear out one or two sizes, keep buying those as singles and leave spares in the van.
Will these bits cover drilling and driving jobs in one kit?
They will cover the drilling side, but you will still want proper driver bits for fixings. That is why plenty of lads keep their drill bits next to their driving gear rather than mixing everything into one battered box.
