The Ridgid 12 Inch Dual Bevel Sliding Miter Saw is unlike any saw I’ve ever used. This saw is capable of cutting a 70-degree miter angle. To achieve

these kind of cuts I have to use an acute angle jig clamped to my miter saw – trust me its a pain in the ass.

Capable of 70-Degree Cuts

This Miter Saw has an industry leading 0-70° miter range. It miters 70° to the left and to the right. It also has a dual bevel design with crown molding stops that actually work! These miter stops are the first design I’ve  seen that I liked.

Can we go back to 70-degrees? cutting at a 70-degree angle is impressive! Angles are a fundamental building block for creating all sorts of shapes, and we cut angles all the time when installing framing and trim. An acute angle is a smaller angle than a right angle [90-degrees]

As I mentioned above,prior to using this saw, I would have to use an acute angle jig, clamped to my miter saw in order to cut sharp angles.

I immediately started thinking of all the siding and trim installations where this saw would be useful for. Many times when making sharp angles I have to resort to the table saw, circular saw, jigsaw or use an acute angle jig.

This saw will cut a 14-1/2” long, 70-degree bevel in a ½ x 6 cedar clapboard. It’s perfect for 4.5 roof pitch siding and trim installs.

I’ve already over-talked the miter capability of this saw. I’m still shaking my head.

This saw has miter and bevel detents with a bypass lever that allows for quick adjustments to the most common angles. In order to achieve sharper angles the saw has a left and right fence wings that slide out to entend the miter fence.

Positive bevel crown molding stops, left and right, at the most common angles;

  • 15°
  • 22.5°
  • 33.9°
  • 45°

Positive miter stops, left and right, at the most common angles

  • 15°
  • 22.5°
  • 31.6°
  • 45°
  • 60°
  • 67.5°

One point to note is the miter fence and detent slot is a thin metal and could possible become worn from use of the detent feature.

LED Lighting System

The Ridgid 12 Inch Dual Bevel Sliding Miter Saw has a switch on top of the saw handle that turns on a led light. The LED light illuminates the saw blade, producing a cut line on th materials being cut. this is one of my favorite features on high miter saws.

Unlike a laser that needs calibrations, this LED light works on every blade and identifies an accurate cut line as well as illuminating the work.

In order to use this feature you simply bring the saw blade arm down to the workpiece. A shadow is projected onto the workpiece, indicating where the sawblade will cut.

Motor

The Ridgid 12 Inch Dual Bevel Sliding Miter Saw spins at 4000 RPMs. It has a 6-foot cord and a 15 Amp motor that was able to cut trim and framing materials.

While using this saw I noticed a vibration and slight wobble to this saw. The vibration sound can be heard in the gears between the motor and the arbor shaft assembly.

Weight

The Ridgid 12 Inch Dual Bevel Sliding Miter weighs 64-pounds and is a beast to lug around. You will want a miter saw stand to transport this bad ass saw.

Ridgid 12 Inch Dual Bevel Sliding Miter Saw ReviewDust Collection

The saw has a built-in-dust collection port the will work with 1-1/4 in. vacuum adapters. The dust bag is pretty much useless, but when connected to a vacuum the dust port captures approx. 75-80 percent of the saw dust.

Saw Footprint

The Ridgid 12 Inch Dual Bevel Sliding Miter Saw measures 22.38 wide x 20.50 h x 38.75 deep.

Cutting Depths

  • At 90-degrees the saw can cut a 2×16 or a 4×6.
  • At 45-degrees the saw can cut a 2×12 or a 4×6
  • A maximum cutting depth of 4-inches

Accuracy

The Ridgid 12 Inch Dual Bevel Sliding Miter Saw was easy to assemble and was accurate right out of the box.

When testing the saw we did notice a 1/64-inch blade wobble. While I might not use this saw for high-end, interior finish work, I definitely would use it on a general work, exterior siding and trim installation.

The Ridgid 12 Inch Dual Bevel Sliding Miter has some very cool features, and sells for only $399.00.

Overall Impression

I’ve always been a fan Ridgid tools. This saw gives the user better functionality and similar features than saws costing almost twice as much. The R4221 can accomplish most carpentry applications within acceptable tolerances.

I think most users will appreciate the ability to cut miters up to 70-degrees whether in the workshop and jobsite.

Kudos to Ridgid for blazing the trail and leading the pack on this innovation.
