Key Features
Overview
Kreg KBC3-BAS Bench Clamp with Bench Clamp Base is a portable benchtop clamping system built for woodworking. assembly. and repeat work at the bench. This is a bench clamp designed for securing workpieces during joinery. routing. cutting. sanding. and drilling. Model Number: KBC3-BAS. If you want the speed of a bench-mounted clamp without giving up flexibility on where you mount it. this setup makes a lot of sense.
The big draw here is Kreg’s Automaxx auto-adjust technology. Instead of stopping to dial the clamp in every time stock thickness changes. the clamp adjusts itself to the material with a squeeze of the handles. That matters when you’re moving between a 2×4. face frame parts. and sheet goods in the same project. You still get thumbscrew pressure regulation. so you can fine-tune how firmly it holds while keeping setup quick.
This clamp handles materials up to 3-1/2 inches thick and gives you a 3 inch reach. which is a practical range for common woodworking tasks. That reach works well for pocket-hole joinery. small panel glue-ups. edge work. sanding hold-down. and light machining support at the bench. The extra-large padded clamp face helps spread pressure more evenly. which is important when you’re clamping finished parts or softer wood that can mark easily.
The included base is what separates this kit from a standard handheld clamp. The bench clamp base is made from cast aluminum for durability. and it mounts into 3/4 inch or 20 mm bench dog holes. If your bench does not already have dog holes where you want the clamp. you can drill a hole and mount the base there. Just as important. you can remove the base and move it to another spot when the layout of the job changes. For a crowded bench. that flexibility is worth having.
The base also swivels 360 degrees. which gives you more control over clamp direction and part positioning. On real projects. that means you can turn the clamp to suit the work instead of forcing the work into one fixed orientation. That is especially useful when you’re holding irregular parts. working near a bench edge. or setting up repeat assembly stations for small production runs.
From a comfort and durability standpoint. this Kreg bench clamp uses all-metal construction with padded grips to reduce hand fatigue during repeated use. If you spend a lot of time opening and closing clamps during assembly. those details matter. The ergonomic grips and predictable squeeze action make it easier to work faster without fighting the tool.
Compatibility is another strong point. The Kreg KBC3-BAS Bench Clamp with Bench Clamp Base works with benches that use standard 3/4 inch bench dog holes. and it is also compatible with Kreg Clamp Trak and Clamp Vise setups. That makes it a good fit for users already invested in Kreg workholding and bench accessories. but it is still easy to use as a standalone clamping solution on a custom bench.
This is a smart buy for woodworkers. cabinet installers. trim carpenters. and serious DIY users who want repeatable clamping without dedicating a permanent vise or fixed clamp to one spot. If your projects involve frequent setup changes. mixed material thicknesses. or bench work where a normal bar clamp gets in the way. this bench clamp setup saves time and keeps the work steady.
Faster Setups for Mixed Material Thickness
This bench clamp is built for the kind of bench work where material thickness changes constantly. The auto-adjusting mechanism keeps the process moving. which is a real advantage during assembly and joinery.
- Automaxx technology adjusts automatically to thick. thin. and in-between materials
- Clamps stock up to 3-1/2 inches thick with a 3 inch reach
Mount It Where the Work Happens
The included base turns the clamp into a movable workholding station instead of locking you into one permanent location. That is useful on crowded benches and even more useful if you build different types of projects on the same surface.
- Base fits 3/4 inch and 20 mm bench dog holes
- Includes anchor bolt and knob for secure mounting
Built for Repeatable Bench Work
For routing. drilling. sanding. and light assembly work. this setup gives you stable hold-down pressure with less clamp repositioning. The 360 Basic Line swivel helps you line the clamp up with the task instead of working around the clamp.
- Cast aluminum base provides durable support for shop use
- Padded grips and a padded clamp face improve comfort and protect the workpiece

Pro Tip
If you do repeat assembly work. leave the pressure where you want it and let the Automaxx mechanism handle thickness changes. Then use the 360 Basic Line swivel to bring the clamp to the part instead of dragging the part around your bench.
