1. Best Utility Knife: Milwaukee FASTBACK Folding Knife
Who it's for: Anyone who opens boxes, cuts cable ties, scores plasterboard, or does any general site work.
The Milwaukee FASTBACK is the utility knife I wish I'd bought years ago. Before this I was buying £3 knives from the discount aisle and binning them when the blade rattled. The FASTBACK is built in a different league — one-handed blade flip, rock-solid lock, and it fits comfortably in a pocket without jabbing you.
Why it stands out:
- One-hand blade deployment (genuinely useful mid-job)
- Blade storage inside the handle
- Far better build quality than the typical site knife
Best for: Electricians, general DIY, tradespeople who want something pocket-friendly.
Where to buy: Available on Amazon UK, Screwfix, and Toolstation. Prices vary — check Amazon for the best current deal.
2. Best Hole Saw Set: DURI Bi-Metal Hole Saw Set
Who it's for: Anyone fitting recessed lights, installing back boxes, cutting through wood or plasterboard.
Hole saws are one of those tools you don't buy until you need one — then you realise you need several sizes. The DURI bi-metal hole saw set is the sensible solution: buy a full set rather than individual cutters, and you're covered for most home improvement jobs.
Key specs:
- Bi-metal construction (cuts wood, plasterboard, soft metal)
- Multiple sizes in one kit — typically 22mm to 100mm+
- Compatible with standard arbors
Why it stands out:
- Excellent value compared to buying individual saws
- Bi-metal holds an edge much better than HSS for occasional use
- Cuts cleanly through plasterboard and pine without burning
Best for: Fitting downlighters, back boxes, waste pipe holes, speaker cutouts.
Where to buy: Amazon UK — check the current price, sets often come up on deal.
3. Best Specialist Bit: hsawbit 40x155mm Wood Auger Bit
Who it's for: Anyone drilling through structural timber, joists, or thick hardwood where a spade bit just isn't cutting it.
Spade bits are fine for thin boards, but when you're drilling 40mm holes through 100mm+ joists, they're slow and they wander. The hsawbit auger bit is the right tool for that job: the central screw pulls the bit through the wood, the cutters score cleanly, and the flutes clear the waste so you're not burning the bit.
Key specs:
- 40mm diameter × 155mm long
- Self-feeding centre screw
- Hex shank — fits most impact drivers and drills
- Comes in a proper storage case
Why it stands out:
- Made running waste pipe through floor joists dramatically easier
- Clean entry and exit hole, no tear-out
- The storage case is actually decent, not an afterthought
Best for: Plumbing, electrical runs, anything needing a clean hole through structural timber.
What to Look for in DIY Tools
Build Quality vs. Price
There's a tendency to buy the cheapest version of every tool and replace them often. That works for consumables like drill bits, but for hand tools and power tool accessories, buying mid-range once is usually cheaper in the long run. The Milwaukee FASTBACK is a good example — it costs a bit more than a disposable knife but it's lasted far longer.
UK Power Tool Compatibility
All the tools above work with standard UK 240V corded drills or 18V cordless platforms. The auger bit and hole saw sets use standard arbors compatible with most drills. Check the chuck size if you're using an older drill (most modern drills accept 13mm).
Where to Buy in the UK
- Amazon UK — usually the best price, good returns policy
- Screwfix — fast click and collect, good for trade brands
- Toolstation — competitive on accessories and consumables
- B&Q / Wickes — good for in-store browsing, less competitive on price
Frequently Asked Questions
What are the must-have tools for a first-time homeowner?
Start with a good cordless drill (18V platform from DeWalt, Makita, or Milwaukee), a tape measure, a spirit level, and a basic bit set. Add a utility knife (the Milwaukee FASTBACK is a great choice) and a few screwdrivers. Specialist tools like hole saw sets and auger bits you can add as specific jobs come up.
Are bi-metal hole saws worth it over HSS?
Yes, for home improvement use. Bi-metal saws are more flexible (less likely to crack) and hold their edge longer when cutting through mixed materials like plasterboard with the occasional embedded screw. HSS is fine for cutting metal specifically; for wood and plasterboard, bi-metal every time.
What's the difference between an auger bit and a spade bit?
A spade bit has a flat paddle shape and relies on speed to cut. It's fine for thin timber but tends to tear out and wander on thicker pieces. An auger bit has a central screw that pulls the bit forward and flutes that clear waste, giving a cleaner hole with less effort on thick timber.
Can I use a wood auger bit in an impact driver?
Yes, if it has a hex shank — which most modern auger bits do. Use a lower torque/drilling mode to reduce the risk of snapping in hardwood. The hsawbit linked above has a hex shank and works well in both drills and impact drivers.
Is Milwaukee worth the price for DIY rather than trade use?
For hand tools like knives, absolutely. For power tools, it depends how often you'll use them. If you're renovating a house or doing DIY most weekends, the Milwaukee M18 platform is worth every penny. If you do one job a year, a mid-range option is probably fine.
