Bosch Pro SDS+ Drill Bits
Bosch SDS drill bits are built for drilling concrete, block and brick fast, with SDS Plus and SDS Max options for proper site hammer drilling.
When you're drilling anchor holes all day or punching through hard block for first fix, this is where you want proper Bosch Professional SDS bits, not cheap ones that blunt early and wander. Bosch SDS Plus drill bits suit most daily fixing work, while Bosch SDS Max drill bits are for bigger holes and tougher concrete. Match the shank to your drill, buy for the material you're actually hitting, and get the Bosch SDS drill bits that will keep cutting cleanly on site.
What Are Bosch SDS Drill Bits Used For?
- Drilling fixing holes into concrete walls and lintels for anchors, frame fixings and mechanical fasteners on first fix and refurbishment work.
- Boring through brick and blockwork for cable runs, pipe clips, trunking and bracketry where a standard masonry bit would just slow you down.
- Opening out larger diameter holes in dense masonry and reinforced concrete when you're fitting services, balustrades or site steelwork.
- Working with rotary hammers on repeated overhead and horizontal drilling jobs where proper hammer drill bits save time and stay true for longer.
- Tackling daily site drilling in hard materials with Bosch drilling accessories that are made to cope with dust, vibration and constant use.
Choosing the Right Bosch SDS Drill Bits
Sorting the right Bosch SDS drill bits is simple: match the bit to the drill, then match it to the material and hole size.
1. SDS Plus or SDS Max
If your drill is a standard site rotary hammer, you will usually want Bosch SDS Plus drill bits for day to day fixing holes. If you are drilling larger diameters or working in harder concrete with a bigger machine, go straight to Bosch SDS Max drill bits and do not try forcing SDS Plus bits to do a heavier job than they were built for.
2. Hole Size and Depth
If you are fitting anchors, clips or brackets, buy the exact diameter and enough working length for the fixing depth plus dust clearance. For deeper penetrations through thicker walls, choose longer hammer drill bits rather than trying to finish the hole with a short bit and making a mess of it.
3. Material on Site
If you are mainly drilling brick and block, most Bosch professional SDS bits in the right size will cover you. If you are regularly into hard concrete, old slab or dense structural work, spend the money on the better concrete drill bits because they stay sharper and track straighter under pressure.
4. How Often You Use Them
If it is occasional snagging or one off fixing work, a couple of core sizes may be enough. If you are on site five days a week, buy a proper spread of masonry drill bits in the sizes you burn through most and keep spares in the van so the job does not stop when one finally dulls off.
Who Uses These Bosch SDS Drill Bits?
- Sparkies use Bosch SDS drill bits for chasing routes, fixing tray and trunking, and drilling neat anchor holes into block and concrete without wasting time on worn masonry bits.
- Plumbers and heating engineers reach for Bosch professional SDS bits when they are clipping pipework, mounting brackets and drilling service penetrations through brick and dense block.
- Builders and general trades keep Bosch SDS Plus drill bits in the case for everyday fixing work, especially when they are setting frames, rails and supports across mixed site materials.
- Groundworkers and steel fixers tend to move up to Bosch SDS Max drill bits for heavier drilling in tougher concrete where smaller shanks and lighter bits are not up to it.
- Maintenance teams swear by trade SDS bits because they need one set of reliable concrete drill bits ready in the van for anything from handrails to plant room fixings.
The Basics: Understanding Bosch SDS Drill Bits
The important bit is not just the diameter on the packet. You need to know the shank type and what sort of drilling the bit is built for, otherwise you end up with poor drilling, extra wear and the wrong bit for the machine.
1. SDS Plus for Everyday Site Drilling
Bosch SDS Plus drill bits fit the smaller and mid size rotary hammers most trades carry for daily fixing work. They are the standard choice for drilling into brick, block and concrete for plugs, anchors, clips and brackets.
2. SDS Max for Bigger Holes and Heavier Work
Bosch SDS Max drill bits are for larger machines and tougher drilling. When the job moves into bigger diameters, deeper holes or harder concrete, SDS Max gives you the strength and energy transfer needed to keep progressing properly.
3. The SDS Shank Does the Gripping and Hammering
Unlike a straight shank masonry bit, the SDS fitting locks into the chuck so the drill can hammer and rotate the bit efficiently. That means faster drilling, less slip in the chuck and better results when you are repeatedly drilling into hard site materials.
Useful Extras to Keep Your Bosch SDS Drill Bits Working on Site
A few sensible add-ons save time, keep drilling cleaner and stop simple jobs turning into a dust covered faff.
1. Bosch SDS Drills
Sounds obvious, but the bit is only as good as the machine driving it. Pair the right Bosch SDS drill bits with the right Bosch SDS Drills so you are not underpowering bigger bits or trying to run the wrong shank altogether.
2. Bosch Dust Extractor Accessories
If you are drilling indoors or overhead, get the right Bosch Dust Extractor Accessories. You will be grateful when you are not breathing the lot in or sweeping up for half an hour after a run of holes.
3. Bosch Dust Extractors & Vacuums
For cleaner drilling in occupied buildings, finished spaces and regular concrete work, hook up to Bosch Dust Extractors & Vacuums. It keeps the hole clearer, cuts airborne dust and makes clean-up much less painful.
4. Safety Glasses
Dust, chips and blown out grit come straight back at you when drilling overhead or into old masonry. A decent pair of Safety Glasses is a basic bit of sense, not an optional extra.

Common Buying and Usage Mistakes
- Buying SDS Max instead of SDS Plus, or the other way round, is the classic mistake. They are not interchangeable, so always match the shank to the drill before you order.
- Using a short bit for a deep fixing hole wastes time and usually leaves you with a rough, dusty hole that does not suit the anchor properly. Buy the correct working length from the start.
- Treating worn hammer drill bits as good enough slows drilling right down and puts more strain on the drill. If the tip is rounded off or progress has dropped badly, replace it.
- Using standard masonry bits in a job that really needs Bosch SDS drill bits is false economy. You lose drilling speed, wear bits out quicker and make harder work of basic site drilling.
- Ignoring dust control on indoor concrete drilling creates more cleaning, worse visibility and a rougher working day. Pair your drilling setup with extraction where the job calls for it.
SDS Plus vs SDS Max vs Standard Masonry Bits
SDS Plus
This is the everyday choice for most trades. Bosch SDS Plus drill bits cover the bulk of fixing and installation work in brick, block and concrete, and they suit the rotary hammers most lads already carry.
SDS Max
Go here when the holes get bigger and the concrete gets tougher. Bosch SDS Max drill bits need a larger machine, but they are the right answer for heavier drilling where SDS Plus starts feeling out of its depth.
Standard Masonry Bits
Fine for lighter drilling in a regular drill or combi, but they are not the tool for repeated hammer drilling into proper concrete. If the job is site fixing in hard materials all day, Bosch professional SDS bits are the better buy.
Maintenance and Care
Clear Dust After Use
Brush or wipe concrete dust off the flute and shank after drilling. Letting dust bake on makes bits harder to inspect and can wear the chuck area faster.
Check the Tip Before the Next Job
If the cutting head is chipped, rounded or running off line, retire it before it ruins a fixing hole. A tired bit costs more in wasted time than a replacement ever will.
Store Them Properly
Do not leave Bosch SDS drill bits rattling loose in the van with breakers and spanners. Keep them in a case or organiser so the tips stay in decent nick and the sizes are easy to grab.
Keep the Shank Clean
A dirty or damaged shank can affect how the bit seats in the chuck. Wipe it down before use so the drill grips and hammers properly.
Replace Worn Bits Before They Slow the Whole Job
Once a bit starts labouring in concrete, do not keep forcing it. Swap it out before you overwork the drill or end up with oversized, messy holes that do not hold fixings right.

Bosch SDS Drill Bits FAQs
Which Bosch SDS drill bit should I use for concrete?
For concrete, use Bosch SDS drill bits matched to both the hole size and the drill you own. For most fixing and anchor work, Bosch SDS Plus drill bits are the standard choice. If you are drilling larger diameters or working in tougher structural concrete, move up to SDS Max. Check the drill first, then buy the bit to suit the job.
Are Bosch SDS drill bits suitable for masonry and brick?
Yes. Bosch professional SDS bits are made for masonry materials including brick, block and concrete. They are a solid choice when you are doing repeated drilling and want faster progress than you would get from a basic straight shank masonry bit.
What is the difference between SDS Plus and SDS Max drill bits?
SDS Plus is the common format for smaller and mid size rotary hammers used for everyday site drilling. SDS Max is larger, stronger and meant for heavier drills, bigger holes and harder work. They do not swap over, so pick the system your machine is built for.
Do Bosch SDS drill bits fit all SDS drills?
No. Bosch SDS drill bits must match the chuck type on the drill. SDS Plus bits fit SDS Plus drills, and SDS Max bits fit SDS Max drills. Always check the drill spec before ordering, especially if the machine is older or shared on site.
Will these bits cope with daily trade use, or are they just for the odd fixing?
They are built for proper site use. Bosch pro SDS bits are the sort of bits trades keep in rotation for repeated drilling in concrete and masonry. That said, no bit lasts forever. If you are hitting rebar, hard aggregate or old dense concrete all week, expect wear and keep spare sizes ready.
Do I need dust extraction when using Bosch SDS drill bits indoors?
If you are drilling indoors, overhead, or in occupied areas, yes, it is worth it. Dust extraction keeps the hole cleaner, improves visibility and cuts the mess left behind. Pairing the drill with extraction is a smart move on cleaner sites and during refurbishment work.
