The Harrows NX90 Steel Tip Darts are built with 90% tungsten, giving them a slim but durable structure. The silver finish is simple yet sharp, pairing well with the included NX90 flights and Supergrip shafts.
When tested, the 21g bomb style darts felt balanced and well-made. The mix of grip styles gave confidence, no matter where the fingers rested on the barrel.
The Harrows NX90 Steel Tip Darts are available in three different weights. All versions share the same barrel length of 42.00 mm, but the barrel width changes slightly with weight.

Finish & Coating
The NX90 features a sleek silver finish that covers the 90% tungsten barrels. The coating is smooth to the touch and has a subtle sheen that gives the darts a professional look.
The smooth surface interacts well with the ring and micro cuts. It allows fingers to slide slightly during release without losing control, which contributes to consistent throws.

Player Feedback
The grip on the Harrows NX90 Steel Tip Darts is built from a mix of ring cuts and micro cuts across the barrel.
At the front of the barrel, fine micro cuts provide a subtle texture. This section feels less aggressive and gives a controlled surface for players who place fingers closer to the nose of the dart.
The main body of the barrel features traditional ring cuts. These rings are cut deep enough to give reliable traction without feeling sharp. The rings are spaced evenly, which creates a consistent grip along the middle portion of the dart.
Toward the rear of the barrel, the ring cut pattern continues, so it also suits players who anchor their grip at the back.
Overall, the ring and micro cuts combined to give a steady, comfortable feel. The design gives just enough texture to inspire confidence without adding unnecessary complexity.
Other Versions of the Harrows NX90
The Harrows NX90 is not limited to the bomb-shaped steel tip design. Harrows also make the NX90 in a straight barrel version, which offers a cleaner, more uniform grip. Players who prefer a simpler profile with less contour often choose straight barrels for their tighter grouping potential.
There is also a soft tip version of the NX90. This design mirrors the steel tip models in grip style and balance, but it is fitted with soft tips for electronic dartboards. That means players who switch between steel tip and soft tip games can keep the same barrel shape and feel, avoiding changes in their throw mechanics.
