Drill Bit Sets for Trade and DIY
A blunt or wrong drill bit wastes time and ruins your work. The right drill bit set makes every hole clean and precise. Here you will find quality drill bit sets for wood, metal, masonry, and multi-material use. Whether you are a tradesperson on site or a DIYer at home, you will find the right set here. All sets are stocked for fast UK delivery.
Drill Bit Sets That Get the Job Done Right
Not every drill bit works on every material. Using the wrong type causes slow drilling and damage. A good drill bit set gives you the right bit for each task.
The best drill bit sets include a range of sizes. They cover common hole diameters for everyday jobs. A well-made set lasts far longer than cheap single bits.
This range includes jobber drill bit sets, HSS sets, masonry sets, wood sets, and mixed-material kits. All products are suited to common power drills and hammer drills used across UK trade and home jobs.
Quick tip: Always match the drill bit to the material you are drilling into. Using a wood bit on metal or masonry will blunt it fast. Check the label before you drill.
Types of Drill Bit Sets Available
Different jobs need different drill bits. Here is a clear guide to the main types. Knowing which type to use saves time and money on site.
HSS Jobber Drill Bit Sets
HSS stands for High Speed Steel. These are the most common metal drill bits in the UK. Jobber drill bits are the standard length for general use. They work well on mild steel, aluminium, copper, and plastics. The best jobber drill bits have a sharp 118-degree point. They are ideal for engineers, fabricators, and general maintenance work.
Masonry Drill Bit Sets
Masonry bits have a carbide-tipped point. They are built to drill into brick, block, stone, and concrete. They must be used with a hammer drill for best results. A masonry drill bit set usually includes sizes from 4mm to 10mm. These cover the most common fixing hole sizes in UK construction.
Wood Drill Bit Sets
Wood bits have a pointed tip and wide flutes. They remove waste quickly. They give clean, splinter-free holes in softwood, hardwood, and sheet material. Some sets include both standard twist bits and flat bits for larger holes. Ideal for carpenters, joiners, and general woodworkers.
Multi-Material Drill Bit Sets
Multi-material bits drill through wood, metal, plastic, ceramic tiles, and light masonry. They save you from switching bits between different materials on the same job. These sets are very popular for general DIY and renovation work in the UK. One set covers a wide range of everyday drilling tasks.
Titanium-Coated Drill Bit Sets
Titanium-coated HSS bits last longer than standard HSS bits. The coating reduces friction and heat during drilling. This keeps the cutting edge sharp for more holes. A good titanium drill bit set is a cost-effective upgrade for regular metalwork.
Cobalt Drill Bit Sets
Cobalt bits are made from HSS with cobalt added to the steel. They handle hard metals like stainless steel and hardened steel. They run hotter without losing their edge. These are the top choice when standard HSS bits struggle. Ideal for automotive, fabrication, and stainless steel work.
How to Pick the Best Drill Bit Set for Your Job
The best drill bit set to buy depends on what you are drilling into. Think about the material first. Then think about the sizes you need.
Drilling into Metal
Use an HSS jobber set for mild steel, aluminium, and copper. Go for cobalt bits if you are drilling stainless or hardened steel. A titanium-coated set is a good middle-ground option for regular metal drilling.
Drilling into Masonry
Always use carbide-tipped masonry bits with a hammer drill. A masonry drill bit set from 4mm to 10mm covers most UK fixing jobs. You need these bits before using our masonry fixings.
Drilling into Wood
Brad-point wood bits give the cleanest holes in timber. Standard HSS twist bits also work in softwood. For larger holes in wood, look for flat bits or spade bits in the set.
General DIY and Home Use
A multi-material drill bit set is the best all-round kit for home use. You get bits that work across wood, metal, plastic, and light masonry. These are the most useful sets to keep in a home toolbox.
Trade and Site Use
Tradespeople need reliable bits that hold up through heavy daily use. Look for sets with HSS or cobalt bits in a durable index case. Larger sets with more sizes give more flexibility across different jobs on site.
Budget vs Quality
Cheap sets blunt quickly and waste money in the long run. Spending a little more on quality HSS or coated bits saves time and frustration. Good bits cut faster, stay sharp longer, and give cleaner holes every time.
Drill Bit Sizes Guide for Common UK Jobs
Choosing the right drill bit size is just as important as choosing the right type. Here is a quick reference for the most common drilling tasks in UK trade and DIY.
| Drill Bit Size | Common Use | Typical Material |
|---|---|---|
| 3mm | Pilot holes, small fixing holes | Wood, metal, plastic |
| 4mm | Wall plugs, small masonry holes | Brick, block, timber |
| 5mm | Red wall plugs, cabinet fixings | Masonry, wood, metal |
| 6mm | Brown wall plugs, conduit clips | Masonry, concrete, wood |
| 8mm | Frame fixings, bracket holes | Concrete, brick, steel |
| 10mm | Anchor bolts, throughbolts | Concrete, hard masonry |
| 12mm+ | Structural anchors, large fixings | Concrete, steel plate |
Always check the product pack of your fixing to confirm the correct drill bit size. Using the wrong size reduces holding strength and can cause the fixing to fail.
HSS vs Cobalt vs Titanium Drill Bits
These are the three most common types of metal drill bits available in the UK. Each has different strengths. Here is how they compare.
HSS (High Speed Steel) bits are the standard choice for metal drilling. They work on mild steel, aluminium, copper, and non-ferrous metals. They are affordable and widely available in sets of all sizes. For most everyday metalwork, a good HSS jobber drill bit set is all you need.
Cobalt drill bits contain a percentage of cobalt in the steel alloy. This makes them harder and more heat-resistant than standard HSS. They handle stainless steel, hardened steel, and tough alloys. They cost more but last significantly longer on hard materials.
Titanium-coated bits are HSS bits with a titanium nitride surface coating. The coating reduces friction and extends the life of the cutting edge. They are a good upgrade over plain HSS for regular use on metal. Note that once re-sharpened, the titanium coating is removed from the tip.
For most UK trade jobs: an HSS jobber drill bit set covers the majority of everyday drilling needs. Upgrade to cobalt only when you are regularly drilling stainless steel or hardened materials.
How to Store and Care for Your Drill Bit Set
A drill bit set lasts much longer with basic care. Drill bits are precision cutting tools. Treat them properly and they stay sharp through many more jobs.
Use an Index Case
Always store bits in a drill index or labelled case. Loose bits knock against each other and blunt the cutting edges. An organised case also means you can find the right size fast on site.
Keep Bits Clean and Dry
Wipe bits down after use to remove metal swarf and dust. Moisture causes rust on HSS bits. Store them somewhere dry. A light oil wipe on metal bits helps prevent surface corrosion.
Do Not Force a Blunt Bit
Forcing a dull bit generates heat and damages both the bit and the workpiece. If a bit is struggling to cut, it needs sharpening or replacing. A sharp bit cuts easily with steady moderate pressure.
Use the Right Speed Setting
Larger bits need slower drill speeds. Smaller bits run faster. For metal, use cutting fluid or oil to reduce heat. For masonry, use hammer mode on your drill.

Frequently Asked Questions About Drill Bit Sets
What is the best drill bit set to buy in the UK?
The best drill bit set depends on what you are drilling. For general use, a good HSS jobber drill bit set covers wood, metal, and plastic. For home DIY, a multi-material set is the most versatile option. For masonry work, buy a dedicated carbide-tipped masonry set.
What are jobber drill bits?
Jobber drill bits are the standard-length twist drill bits used for everyday drilling. The length is roughly 9 to 14 times the diameter of the bit. They fit most standard power drills and pillar drills. The best jobber drill bits are made from HSS or cobalt steel.
Can I use one drill bit set for wood, metal, and masonry?
Not with standard bits. Each material needs a different bit type. A multi-material drill bit set is designed to handle several surfaces, but a dedicated set for each material always gives better results and lasts longer.
What drill bit do I need for concrete?
You need a carbide-tipped masonry drill bit. Always use it with a hammer drill. Standard HSS bits will not penetrate concrete effectively and will blunt very quickly.
How many bits should a good drill bit set have?
A useful general-purpose set has at least 13 to 19 pieces. This covers the most common sizes from 1mm to 10mm. Larger sets with 25 or more pieces give more coverage for trade work. A bigger set is not always better if you only use a few common sizes.
Are cobalt drill bits better than HSS?
Cobalt bits are harder and more heat-resistant than standard HSS. They are better for drilling stainless steel and hard alloys. For mild steel, aluminium, and everyday metals, a quality HSS set performs very well and costs less.
What size drill bit do I need for a wall plug?
It depends on the plug size. A red plug needs a 6mm bit. A brown plug needs a 7mm bit. Always check the drill size printed on the plug packaging for an accurate match.
