Kreg 20V Ionic Drive 3/8-in. Cordless Compact Impact Wrench, Tool Only (KPTCWR375B)
Kreg 20V Ionic Drive 3/8-in. Cordless Compact Impact Wrench, Tool Only (KPTCWR375B)
Key Features
Overview
The Kreg 20V Ionic Drive™ 3/8" Compact Impact Wrench (Tool Only) is built for users who need solid fastening and removal power in a smaller, lighter package. This is a compact impact wrench designed for loosening and tightening nuts and bolts in shop, garage, and jobsite work. Model Number: KPTCWR375B. If you already run Kreg's 20V platform and want a bare tool that handles common mechanical and assembly tasks without the size of a full-size wrench, this is the one to look at.
The big story here is usable power. Kreg rates it at up to 275 ft-lbs of breakaway torque with up to 3,700 impacts per minute, which is enough to deal with tough fasteners while still keeping the tool compact. That matters when you're working on lag bolts, structural fasteners, shop fixtures, lawn equipment, or general repair work and do not want to drag out a heavier impact wrench for every job.
Kreg also gave this tool the kind of control features that make a difference once you're off the spec sheet and actually using it. You get four speed settings, made up of three standard modes plus Assist Mode. The variable-speed trigger lets you ease into a fastener instead of hitting it full force right away, and Assist Mode is there to help reduce overtightening on install and runout on removal. For anyone working with smaller hardware, finished assemblies, or mixed materials, that extra control is worth having.
The physical design is one of the strongest parts of this tool. At just 4.85 inches long and only 2.2 lbs, it is clearly aimed at tight-space access and reduced fatigue. That shorter nose helps when you're working between framing members, around machinery, inside utility spaces, or anywhere a larger cordless impact wrench starts getting awkward. The all-metal gear casing adds durability where it counts, especially for users who are going to keep this in a truck, shop, or daily-use tool setup.
Socket changes stay quick thanks to the 3/8 inch anvil with friction ring. That setup is a good fit for users who swap sockets often and want a straightforward, secure connection without wasting time. The built-in LED work light is another practical touch. It helps in darker corners, under equipment, and in enclosed work areas where overhead lighting is never where you need it.
As a bare tool, this version is best for buyers already on the Kreg 20V Ionic Drive cordless platform. Batteries and charger are not included, which keeps the cost down if you already own compatible power sources. If you are starting from scratch, just know you will need to add a battery and charger before you are ready to work.
Who should buy it? This compact impact wrench makes the most sense for serious DIY users, woodworkers, installers, mechanics doing lighter-duty work, and contractors who want a second impact wrench for tighter spaces and smaller hardware. It is especially useful when control and access matter as much as raw output. If your work regularly jumps between assembly, maintenance, fastening, and bolt removal, this tool hits a smart middle ground between power, size, and precision.
Compact Power for Tight Access
This compact cordless impact wrench is built for the spots where a larger tool gets in the way. Short length, low weight, and solid torque output make it easier to work around framing, equipment, and assembled projects.

Pro Tip
Use Assist Mode when starting smaller fasteners or working on finished assemblies. It gives you a little more margin against overdriving, which is exactly what you want when the job calls for control more than brute force.
