The Crain 336 Undercut Saw is a jobsite essential for achieving clean, professional-looking flooring installations.

The Crain 336 Undercut Saw is a jobsite essential for achieving clean, professional-looking flooring installations. Designed to undercut door jambs, casings, and trim with accuracy, this compact hand saw helps flooring slide neatly underneath which goes a long way in eliminating awkward gaps and reducing the need for filler or extra trim work.
This undercut saw is used to trim door jambs and moldings to the exact height of your flooring and underlayment. By resting the saw flat on the floor, you get a consistent, level cut that allows wood, laminate, vinyl, or engineered flooring to tuck cleanly underneath for a seamless finish.
Built with a rigid steel blade and durable handle, the Crain 336 delivers controlled cutting power without flex. The fine-tooth blade produces smooth, precise cuts while maintaining stability, even in tight spaces around doorways and corners.
The low-profile blade design makes it easy to work close to the floor, while the ergonomic handle provides a secure grip for steady, confident cutting. It’s lightweight enough for extended use, yet sturdy enough to stand up to daily professional demands.
If you want cleaner transitions and a more professional finished look, the Crain 336 Undercut Saw is a simple, reliable solution. It reduces installation time, improves accuracy, and helps ensure flooring fits exactly as intended around doorways, all without overcomplicating the job.
