Sneak Up on the Perfect Miter Fit

Creating perfect 45° miters has never been easier. The Miter Trimmer is ideal for making professional quality picture frames, mitered cabinet doors, mitered trim pieces, or for when you simply need to cleanly and accurately trim a workpiece to final length.

Made of solid cast iron, the Miter Trimmer has a pair of adjustable fences that can be set anywhere from 90° to 45° for perfect fitting miters. Both the right and left fence have dedicated stops at 90° and 45° for quick setup at these most commonly used angles and can be set to any angle in between.

The ¼” thick razor-sharp high carbon steel blades are set at a skew to slice through the material and produce perfectly clean tear-out free cuts in end grain ready for glue or finish. The exceptional heft, long removable lever arm, and rack and pinion gear drive mechanism allow you to take surprisingly thick or whisper-thin shavings with ease.

With the capacity to trim a 1" x 6" board (3/4” x 5-1/2”) at 90° or a 2" x 4" board (1-1/2” x 3-1/2”) at 45°, this trimmer is ready to tackle projects big and small. It is capable of hogging out large amounts of material quickly and unlike most power tools, can trim workpieces to final length a few thousandths of an inch at a time so you can sneak-up on a perfect fit.

We now offer replacement blades for the Precision Miter Trimmer —These extremely sharp blades are the same ones that come on your Precision Miter Trimmer, and should last a very long time. Whether you don't feel comfortable sharpening these blades yourself, or just want a spare to have on hand, these replacement blades will keep your miter trimmer going when one set eventually needs honing.

Infinity's Precision Miter Trimmer

If you're like most woodworkers you know that it can be difficult to cut mitered workpieces. Cutting to the perfect length on the first try, or even the second, is tricky. Even more difficult is making the second cut at the miter saw or table saw. Shaving off that last little bit for a perfect fit never quite works. This is where the Precision Miter trimmer (101-612) saves the day. It makes it easy to cut perfect miters and leaves a glass-smooth finish every time.

Cast Iron Construction

The Precision Miter trimmer (101-612) is a tool most commonly seen in picture frame shops, for good reason, almost every cut on a picture frame is a 45° miter. This Precision Miter Trimmer is made of sturdy cast iron and weighs in at a solid 32 pounds. Both of the cast-iron fences have dedicated stops at 45° and 90° and can be set anywhere in between. The two high carbon steel blades measure a massive 1/4" thick and come razor sharp right out of the box. I know, everybody always says their tools are razor sharp and ready to work. Honestly, these blades have the keenest factory edge of any tool I have had the pleasure of using. So, when you use your Precision Miter Trimmer for the first time, be careful!

With a long cast-iron handle, the Precision Miter Trimmer can take shaving from paper-thin to extra thick.

Aggressive Shear Angle

The blades are set at a steep 45° shearing angle that allows them to slice off paper-thin shavings or chop off material like a lumberjack's ax. This shearing action paired with the long cast iron handle allows controlled and effortless cuts both thick and thin. Also, the handle fits into a dovetailed receiver so it can be easily installed and removed without tools for easy storage.

The cast-iron fences allow cuts anywhere from 90° to 45° and can cut both left and right-handed for the ultimate versatility.

Not Just For Pine

I get asked all the time if the Precision Miter Trimmer is just for the pine and poplar moldings you see in picture frame shops. The answer is, absolutely not. While the miter trimmer slices these soft species without missing a beat, we use ours on wood including Maple, Walnut, Cherry, Oak, and even Hickory. Not to mention, it also has an impressive cut capacity. Cutting a 1x6 (3/4" x 5-1/2")  at 90° is no problem. And, at 45° the miter trimmer can handle a 2x4 (1-1/2" x 3-1/2") without missing a beat. This ability to cut large workpieces and furniture grade hardwoods make it extremely versatile.

Top-Trim Attachment

We're now offering an extra accessory for the miter trimmer that allows working from the inside of a molding or frame piece. Often we mark our cut-mark on the inside of the frame to be more precise, but when we get to the trimmer, the mark can't be seen. This top-trim accessory holds the workpiece in place and allows easy view of our inside mark. 

The extension support at the top helps steady the workpiece, while the red clamp slips over the existing fence.Top-Trim Attachment for the miter trimmer . Great for working with picture frames when working from the inside of the rabbet.
