CountyComm UAS Command Essentials Precision Screwdriver Set: A Field-Ready Bit Kit Under $20
A 30-bit precision screwdriver set from CountyComm and Maratac, built for drones and everyday electronics, with a clever polycarbonate capsule case.
Introduction
CountyComm has built a reputation for practical, field-oriented gear, and this latest release fits that pattern well. The UAS Command Essentials Precision Screwdriver Set, made by Maratac, is a 30-bit precision kit with an aluminum driver, packed in a capsule case designed for field use. It was created with drones and unmanned aerial systems in mind, but it works just as well for general electronics repair or everyday tasks like tightening a sunglasses hinge.
The best part is the price. The set sells for $19.95, which is roughly half the price of comparable aluminum-handle bit kits, and it ships as a limited run with no certainty about future availability.

Who This Product Is For
This set makes sense for anyone who works on drones, small electronics, or precision fasteners and wants a compact kit that lives in a pocket, vest, or vehicle. If you already carry a small 4 mm bit kit, this is a natural upgrade, and if you keep specialty bits around, the included driver accepts any standard 4 mm bits, so you can swap in your own.
Main Strengths
The 30 bits are 34 mm long and made of chrome vanadium steel hardened to 55 HRC, a solid choice for small bits that need to resist wear and stay sharp. The bit selection covers most of the usual suspects: security Torx (with holes) from 6 through 15, standard Torx, slotted, Phillips, hex, Y-type, star, U 2.6, triangle, and the 2.5 mm cross.

The bits sit in the case in a way that keeps them secure during carry, yet each one slides up and out easily and drops straight into the anodized aluminum 4 mm bit holder. The holder is magnetic and the bits stay put in use. The handle itself is a highlight: it is short and well balanced, fits comfortably in the hand, and feels better in use than some heavier, tail-heavy aluminum drivers.
Things to Consider Before Buying
The case is a heavy polycarbonate capsule with an aluminum wrap running over a silicone base. It is drop tested and holds both bits and driver snugly, and the whole package measures about 4.2 by 2.2 inches and weighs 7.4 oz. That is a genuinely pocketable footprint, but it is still a capsule that needs to be opened before you work, so it suits people who like a secured kit rather than an open roll.
The set does not yet carry an NSN number, though one is reportedly being pursued. This also appears to be a limited or overrun run, so stock may not last and future availability is uncertain.

Buying Advice
At $19.95, the value here is hard to argue with. Larger aluminum precision kits can cost about twice as much, and while those may include a few more bits or extra accessories at the top end, this set covers the fastener types most people actually encounter in drones and small electronics. The driver also accepts any of your existing 4 mm bits, which extends its usefulness well beyond the 30 included tips.

If you want a field-ready precision kit that is compact, well executed, and easy on the wallet, this is one of the more interesting 4 mm bit sets currently available.
Conclusion
The CountyComm UAS Command Essentials Precision Screwdriver Set by Maratac delivers a thoughtful bit selection, a comfortable aluminum driver, and a genuinely clever drop-tested capsule case, all at a price that undercuts most of the competition. Given the limited run, it is worth picking up sooner rather than later if it fits your kit.
