Metabo HPT Impact Drivers Compared: 18V Triple Hammer Bolt vs 36V Triple Hammer vs WH18D

Introduction

Metabo HPT has refreshed its impact driver lineup with the new 18V Triple Hammer Bolt, alongside the 36V Triple Hammer and the budget-friendly WH18D. All three are competent tools, but they serve very different buyers, and the differences between them matter more than the spec sheets suggest. After putting the new 18V Bolt through its paces and comparing it with the rest of the lineup, one clear winner emerges for most people, and it is not the one you might expect.

What You Get in the 18V Triple Hammer Bolt Kit

The 18V Triple Hammer Bolt is Metabo HPT’s new-generation impact driver, and the kit configuration is generous: the tool, two 2.0Ah batteries, and a charger, currently listed at around $129 on Amazon. Note that stock has been inconsistent, so you may need to wait a couple of weeks for delivery.

The tool itself shares its grip, exterior shell, and LED lighting with the 36V version. In everyday use, the housing and ergonomics are effectively identical; the real difference is power, and as we will see, even that gap is smaller than expected.

The Case Is Genuinely Useful

One overlooked detail: the included case is a real improvement over older Metabo HPT cases. The first two latches open the main compartment for the driver, with room for a charger or an extra battery. A third latch releases an additional top compartment for screws, bits, or blades. It is solid enough to actually keep and use rather than toss, though the all-plastic latches are the weakest point and may need care over a few years of use.

The Budget Baseline: WH18D

At the entry level, the WH18D is the most affordable option in the current lineup. It has just been refreshed into a new generation, with basic features: no speed control on the front and a single LED light. Despite the simplicity, it is a very capable driver, and the kit with a drill, two batteries, and a charger runs about $150 on sale, down from $200. For anyone who just needs a reliable driver without extra settings, it is hard to beat at that price.

The 36V Triple Hammer: Do You Really Need It?

The 36V Triple Hammer is the powerhouse of the lineup, but the case for buying it is thinner than it looks. Its main advantage over the 18V Bolt is roughly 50 more inch-pounds of torque, and in side-by-side testing the two are so close that the difference is difficult to notice in practice.

There are two other downsides worth knowing. First, the 36V tool cannot use compact 18V batteries; you are limited to the larger multivolt packs or the bigger 8Ah battery. Second, buying the 36V tool alone costs almost the same as the full 18V kit with two batteries and a charger.

Battery Flexibility Is the Real Advantage

Battery compatibility is where the 18V Bolt pulls ahead decisively. Older-generation Metabo HPT batteries noticeably underperform on these tools; switching to the newer 2.0Ah packs already brings a visible power increase, and pairing a multivolt battery with an 18V tool unlocks significantly more performance thanks to the higher power draw capability.

That means the 18V Bolt can run light and compact with a 2.0Ah pack, or hit its highest power levels with a multivolt or 5.0Ah battery. The 36V tool simply does not offer that flexibility.

Smoothness Worth Paying Attention To

Beyond raw numbers, the new Bolt generation is a clear step up in refinement. The triple hammer mechanism is far smoother than the previous generation, making driving screws noticeably easier and more comfortable. The previous 18V generation was criticized as underpowered, but much of that came down to the older batteries rather than the tool itself. With modern batteries, that complaint largely disappears.

A Note on Gray Market Tools

The 36V tool is also available internationally under a different brand name for around $130 shipped, and it is the exact same tool made in the same factory, just with different color shells. However, that route is not necessary given how well the 18V Bolt kit is priced domestically.

Buying Advice

If you are choosing between these three, the 18V Triple Hammer Bolt is the pick for most buyers. It is cheaper than the 36V, works with virtually any Metabo HPT battery from compact 2.0Ah packs up to multivolt and 5.0Ah options, and delivers nearly identical real-world power. The triple hammer smoothness alone makes it a pleasure to use, and in kit form the effective cost per tool drops to roughly $75, backed by a lifetime warranty.

Choose the WH18D if you want the lowest-cost entry point and do not need multiple speed settings. Consider the 36V only if you specifically need the larger battery ecosystem, since its power edge is marginal. And if you already own older Metabo HPT batteries, replace them: the tools perform meaningfully better on the newer packs.

Conclusion

The 18V Triple Hammer Bolt earns the top spot in Metabo HPT’s current impact driver lineup. It combines near-flagship performance, excellent battery flexibility, a genuinely useful case, and a kit price that undercuts the 36V alternative without a meaningful power penalty. For most users, it is the smartest buy of the three.
