Hitachi 6-Gallon 145 PSI Air Compressor Nailer Kit Good but Under-Powered

Hitachi 6-Gallon 145 PSI Nailer Kit Hitachi's 6-gallon air compressor and nailer kit has one of the better nail guns on the market and a small, but workable compressor.

I like this package for the nailers. The 15-gauge brad nailer handles a full-range of brad lengths, from 5/8" to 2". It is light in weight and comfortable in my hand. It offers on-tool depth-of-drive adjustment and tool-free jam clearance. The plastic-tipped safety is located behind the nose, so you have unobstructed views of the brad placement from either side or the front. It is the only brad nailer with a switch for changing from sequential firing to bump firing. Missing are a trigger lock and a belt hook (but I’ve never used either of those in my work).

The obvious feature of the finish nailer is the angled carriage. A nailer’s nose can be maneuvered into inside corners to, for example, facilitate baseboard and crown molding installation — if its nail carriage isn’t at right angles to the nailer head. Maybe it’s just the novelty of it, but I want it. I should point out that the angled carriage means you have to buy nails in clips of a matching angle.

The nailer’s other features match those of the included 18-gauge brad nailer — no depth-of-drive adjustment, but switch-controlled firing mode change and tool-free jam clearance. The safety is heavier, but this gun is almost twice the size and weight of the brad nailer. Its tip loops from side-to-side around the front of the nose.

The compressor is not the best of the lot, but it’s a good one nonetheless. A 1+ hp motor drives the compressor, feeding a six-gallon pancake tank. (This one looks more like a buttermilk biscuit to me.) It delivers 2 CMF at 90 PSI. The rated maximum pressure is 145 PSI.

All the mechanicals sit atop the tank, fully enclosed in a black plastic housing that’s topped by a lift handle. A bit of a groove formed where the housing meets the tank serves as a cord wrap, and the plug is molded to squeeze onto the cord, securing the wrap. The controls are grouped on the front of the housing, with a red pull-push power switch on the right side, the two couplers, regulator and the safety relief valve in a line across the front, and the two pressure gauges just above the regulator knob.

Rounding out the package are a green 1/4" x 25' PVC hose and a soft bag for stowing the two nailers.

This Hitachi kit is sold only by Lowe’s. Though Hitachi USA supplied me with the package, it isn’t listed on the manufacturer’s U.S. website.
