Bosch 1617EVSPK Best Overall
- Weight
- 18.2 lb
- Amperage
- 12 A
- Speed Range
- 8,000-25,000 RPM
- Bases Included
- Fixed and plunge
A plunge base plus a fixed base is the most useful shape this tool comes in, and the Bosch 1617EVSPK is the kit we recommend first. A 12-amp, 2.25-horsepower motor clips into either base through Bosch's quick-clamp system, so the plunge base takes your stopped grooves while the fixed base stays bolted to a router table. What settles the choice is the microfine depth adjustment: you dial bit height in small, repeatable increments instead of nudging the housing and hoping.
The 8,000-to-25,000-RPM range covers a big raised-panel bit turned slow and a small trim bit at full speed, and the constant-response circuitry holds speed when the cutter loads up in oak or hard maple. Both collets come in the box, 1/4-inch and 1/2-inch self-releasing, so nothing stops you from running big-shank bits. It's a complete kit in the way that matters after the first month: the 16mm and 24mm wrenches and the carrying case mean a bit change never turns into a search for the right tool with glue already drying.
Two things to accept before you buy. The motor is a firm fit in the plunge base's clamp, and switching bases is the slowest part of using this kit, so batch your plunge cuts rather than swapping back and forth every few minutes. And at 18.2 pounds as listed it's the heaviest kit here, which steadies it across a wide panel and gets tiresome working overhead.
The durability question mark sits on the plunge base rather than the motor: cracks in that metal housing are the failure to watch for, which is a good argument for keeping the kit in its case between jobs and not dropping it off a bench.
What We Like
- Two bases, fixed and plunge
- Microfine depth adjustment for repeatable heights
- 12-amp motor holds speed in hardwoods
- Both 1/4-inch and 1/2-inch collets included
Worth Noting
- Heaviest kit here at 18.2 pounds
- Motor is stiff to swap between bases
Our pick for most buyers: two bases, 2.25 horsepower, and the most precise depth adjustment here, in a kit that handles handheld and table work.
