RIDGID 18V Brushless Cordless Jig Saw (R86344B) review

This is a document-based assessment, not a hands-on test. The useful story in the R86344B is a relatively complete cordless cutting setup at the tool-body level—but an incomplete power package. Its control and dust options are useful on paper; buyers still need to match the correct blade, battery system, hose and box contents to the work they actually plan.

The exact R86344B package and body

RIDGID's U.S. page identifies R86344B as an 18V brushless jig saw sold tool-only. The listed carton includes the R86344 saw body, a dust-port attachment and a T-shank wood-cutting blade. Battery and charger are separate. That distinction matters more than the orange-and-black product image: a tool-only listing is not ready to cut unless you already have a compatible RIDGID 18V battery and charger. RIDGID says the saw is compatible with its 18V batteries; this is not evidence that packs from another brand will fit.

The body is a top-handle design with a front LED, variable-speed trigger and a four-mode speed selector. The published stroke is one inch and the stated maximum is up to 3,450 strokes per minute. Those figures describe the tool's mechanism, not a promise that every blade/material combination will cut cleanly at maximum speed. RIDGID also advertises up to 150 linear feet with a separate 18V MAX Output 4.0Ah battery; treat that as a manufacturer claim tied to that pack, not measured runtime in a particular cut.

Blade fit, material and action need to agree

The exact R86344 operator's manual says the clamp is for T-shank blades only. The included T-shank wood blade establishes one starting blade, not a universal answer for metal, laminate or fine-finish work. Check the blade's purpose and tooth pattern for the stock, and follow the manual's installation steps; no metal-cutting blade is listed in this box.

RIDGID's manual lists wood and wood products, thin sheet metal, plastics and laminates as applications. Its metal-cutting section is unusually concrete about one boundary: metal and conduit require the no-orbit position 0. The maker's product page also advertises four orbital settings, and the exact image shows an indexed 0–3 dial. There is no complete R86344 material-by-orbit chart in the checked instructions, so a buyer should not import the predecessor R8832's chart wholesale. The variable speed selector guidance and the separate orbital dial are different controls; start from the exact R86344 instructions and test on scrap when cut edge or tracking is important.

RIDGID claims reduced vibration compared with R8832B, its named previous model. That is useful as a generation-to-generation manufacturer claim, not a comparative measurement here. The manuals also reveal a practical distinction: R86344 is T-shank only, while the R8832 manual allows both T- and U-shank blades. If you own a mixed blade drawer, verify the shank before choosing the newer tool; do not assume an older clamp rule carries over.

Blower and vacuum are separate dust choices

A cutline blower pushes debris away from the blade path; it does not collect dust. The manual describes a switchable alternative: turn off the line-of-sight air, fit the rear dust-collection attachment, connect a hose and run a separate vacuum. The current exact-model RIDGID product information lists compatibility with 1-1/4-inch and 1-7/8-inch hoses. Those nominal connections do not guarantee that an unlisted hose, reducer or extractor will attach without checking the actual accessory.

The same manual says the R86344 vacuum attachment can remain in use with the base set for beveling. That is a useful documented interaction rather than a guess from a product photo. The shoe adjusts up to 45 degrees left or right. A bevel still needs a correctly positioned, locked base; the manual's setup procedure, not the advertised maximum alone, governs a safe and accurate angle. Blower and vacuum are alternate switch modes, so this is not simultaneous cutline clearing and dust capture.

Who should shortlist it—and what remains unknown

R86344B makes the most sense to a RIDGID 18V owner who wants a brushless top-handle tool with a T-shank clamp, orbital control, a cutline blower, a supplied dust port and bevel adjustment. The included wood blade means the package is not accessory-free, but it's still tool-only: battery and charger must be budgeted separately. If external extraction matters, check that the exact seller package includes the attachment and match the hose connection before relying on the dust route.

The checked R86344 sources do not publish a maximum cutting depth or material thickness, and they do not establish cast-iron/hard-metal or ceramic capability. A one-inch stroke is not one-inch cutting capacity. Nor does the evidence establish a measured cut quality, runtime, vibration level or user comfort. The manufacturer page's 20% vibration and 150-foot runtime statements should stay attributed to the maker.

For a useful comparison, put R86344B next to the exact older R8832B assessment, then compare more than the shared 18V label: note the tool-only package, T-only blade interface, available dust routes and the R8832-specific action chart. Before purchase, verify the model plate and carton suffix, confirm the battery/charger situation, check the actual hose and attachment, and consult the R86344 manual for blade and metal settings. No current retailer inventory, price or individual-unit condition is established here.
