Draper 31 Piece Precision Screwdriver & Bit Set review

Precision screwdrivers are very useful for small-scale jobs. Draper’s 31 Piece set has a lot of competition to fend off. How does it stack up?

Draper 09550 precision screwdriver set being tested

by Chris Williams |

The requirements of a precision screwdriver, or indeed regular screwdriver are very simple: they need to be well made and good to use.

There are so many unbranded precision screwdriver sets available from online retailers such as Amazon that are neither of these, but people get sucked into buying them because they are super cheap. But cheap tools being rubbish? Go figure.


Draper is one of the big and established UK names in tools that’s been around for about a century. It produces a massive range of hand and power tools for DIYers and professional tradespeople alike.

Draper has a well-cemented reputation for balancing quality and value and we hope this stands true with its 31 Piece Precision Screwdriver & Bit Set.

How we tested it

We used the Draper set for tinkering with the RC rock crawlers we have on test. In terms of car-related applications, this is a very important one for precision screwdrivers. Rock crawler bodies sometimes have screws in funny places that test the reach and magnetic strength of the handle.

The test

Magnetic bit holder: This was a simple case of inserting the bits into the handle and seeing if the magnetic hold kept them in place and without jiggling around. We’re pleased to report the kit passed with flying colours. The bits are held firmly into the handle but are easy to remove.

The handle: Without any bits, the handle is 11.7cm long, which is a good size for adult hands. The grooves and shape make it comfortable to hold too, and as an excellent touch, the black sections are rubberised for grip.

Bits: Maths fans will have worked out that given this is a 31-piece set, there are 30 bits:

6 x plain slot bits: 1.5, 2.0, 2.5, 3.0, 3.5, 4.0mm

4 x cross slot bits: No.00, No.0, No.1, No.2

8 x Draper TX-STAR bits: T4, T5, T6, T7. T8, T10, T15, T20

7 x hex bits: 1.0, 1.3, 1.5, 2.0, 2.5, 3.0, 4.0mm

1 x star bit: 2mm

1 x round bit: 1mm diameter

1 x triangle bit: 3mm

1 x tri-wing security bit: No.3

1 x spanner security bit: 2.6mm

These are made from chrome vanadium steel. Like the handle, they’re very well-made and perform very well. They don’t have any defects and grip fasteners firmly.

We commend the inclusion of the two security bits, the tri-winged bit especially which will come in very handy in fixing consumer electronics the manufacturer deliberately tries to discourage.


Having the single handle and interchangeable bits is certainly the way to go for a precision screwdriver set (and regular size, casual-use screwdrivers) because it’s more compact and easier to find the right bit.

Draper’s staple traits of value and quality are evident in this set. The only things that seem like they might not last are the plastic clips on the case. Other than that, everything will go the distance.

This set includes all the essential bits and a couple of extras without going overboard and offering 100 different bits. It’s not necessary because the No. 00 cross slot, for example will work on smaller sizes too.

This is the ideal precision screwdriver set for any relevant project such as adjusting car models to replacing wristwatch batteries.

Pros Cons
• All the bits you need, none you don’t • Flimsy case clips
• Good build quality
• Strong magnet
