7 Best Dry Wall Saws For Clean Cable Routing

Whether mounting a new television in the family room or upgrading to high-speed internet, running cables behind finished drywall is a common home project. Cutting into your walls can feel intimidating, but the right tool makes the process clean, controlled, and stress-free. Choosing the correct jab saw ensures you minimize dust and avoid damaging the studs or hidden utilities lurking behind the gypsum.

Klein Tools 31737: The All-Around Pro Choice

When a project requires high-frequency use or reliable, consistent performance, the Klein Tools 31737 stands out. It features a heavy-duty, hardened steel blade designed to puncture drywall without needing a starter hole, which simplifies the process for beginners.

The handle is ergonomically designed, offering a firm, rubberized grip that remains secure even if hands get sweaty during a long installation. This balance of durability and comfort makes it the go-to choice for homeowners tackling multiple cable runs throughout the house.

• Best for: Homeowners who anticipate multiple DIY projects over several years.
• Bottom line: It is a professional-grade tool that offers long-term reliability for a reasonable price.

DeWalt Folding Jab Saw: Best for Compact Storage

For those living in apartments or homes with limited tool storage, the DeWalt Folding Jab Saw is a practical space-saver. It functions like a pocket knife, allowing the blade to fold neatly into the handle when not in use.

This design prevents the blade from snagging on other tools in a drawer or scratching nearby items in a crowded workshop. It is exceptionally convenient for quick, occasional tasks where a full-sized fixed-blade saw would be overkill.

• Best for: Minimalist tool collections and shared living spaces.
• Bottom line: Convenience and portability are the primary advantages, sacrificing only a marginal amount of rigidity compared to fixed-blade models.

Milwaukee Rasping Jab Saw: For The Cleanest Edges

Cutting drywall often leaves ragged, uneven edges that make installing low-voltage mounting brackets or faceplates difficult. The Milwaukee Rasping Jab Saw addresses this by incorporating rasping holes along the side of the blade.

As the saw cuts through the material, these integrated edges act like a file to smooth the perimeter of the hole simultaneously. This feature significantly reduces the need for secondary sanding or cleanup, leading to a much tighter, more professional fit for your wall plates.

• Best for: Perfectionists looking to ensure a seamless fit for electrical and AV components.
• Bottom line: The dual-purpose design saves time on prep work and finishing.

Stanley FatMax Jab Saw: Top Pick for Occasional Use

If the need for a drywall saw arises only once every few years, the Stanley FatMax is a dependable, cost-effective solution. It is built with a sturdy handle and a sharpened point that pierces drywall with very little physical effort.

While it lacks some of the advanced features of premium models, it excels at the basic task of creating clean, plunge-cut openings. It is a no-frills tool that serves its purpose well without requiring a significant financial investment.

• Best for: Budget-conscious homeowners performing occasional home updates.
• Bottom line: A reliable performer that proves expensive tools are not always necessary for light household work.

LENOX Tri-Fold Jab Saw: Most Versatile Blade Saw

The LENOX Tri-Fold Jab Saw offers unique flexibility by allowing the blade to lock in multiple positions. This design is particularly useful when cutting in tight corners or against baseboards where a standard straight blade might be hindered by floor obstructions.

The handle is rugged and weather-resistant, making it a great option if storage space includes an unheated garage or shed. Its ability to adapt to awkward angles makes it a versatile problem-solver for complex cable routing paths.

• Best for: Projects involving tight spaces, near floors, or behind furniture.
• Bottom line: The adjustable locking positions provide access that other saws simply cannot match.

WORKPRO 3-Piece Set: Best Value for Multiple Jobs

For households starting their tool collection from scratch, the WORKPRO 3-piece set provides everything needed for diverse wall-cutting scenarios. Including multiple blade sizes or types, this set covers different levels of precision required for various cable housings.

Having a set ensures that if one blade becomes dulled after heavy use, another is readily available. It is an efficient way to stock a tool chest, ensuring you are never caught without the right size for a specific project.

• Best for: First-time homeowners and those building a comprehensive home maintenance kit.
• Bottom line: You receive high utility across multiple tools for a price comparable to a single premium saw.

Goldblatt Pro Jab Saw: The Heavy-Duty Workhorse

The Goldblatt Pro Jab Saw is designed for those who prioritize durability above all else. With a thick, tempered blade that resists bending, it can handle tougher materials than just standard drywall, such as fiber cement board or thicker backing materials.

While it is heavier and bulkier than a folding saw, the trade-off is unmatched strength and stability during long, controlled cuts. It is a tool designed to last for decades, becoming a staple in a well-equipped workshop.

• Best for: Heavy-duty users or those tackling renovations beyond simple cable routing.
• Bottom line: An investment in long-term utility that handles the toughest cutting jobs with ease.

How to Cut Safely and Avoid Wires or Plumbing

Before starting any cut, utilize a stud finder to identify the location of wood framing, which helps estimate where wires might be stapled. Never push the blade deep into the wall; keep your cuts shallow—about half an inch—to avoid piercing electrical lines or PVC pipes located behind the board.

If the wall feels “tough” or inconsistent while cutting, stop immediately and use a small mirror or a borescope to inspect the cavity. It is far better to take a few extra minutes to verify what is behind the drywall than to accidentally cut into a utility line.

• Safety Tip: Always wear eye protection, as drywall dust is abrasive and can fall directly into the eyes when cutting overhead.
• Pro Tip: If possible, turn off the power to the circuit you are working near to prevent any risk of electrical shock.

Jab Saw vs. Keyhole Saw: Which Do You Really Need?

While the terms are often used interchangeably, there is a subtle difference in construction. A traditional keyhole saw typically has a thinner, more flexible blade intended for more intricate, curved cuts in woodwork or softer materials.

A jab saw, conversely, is specifically reinforced for the rigidity required to plunge-cut through heavy, abrasive drywall. For cable routing, you almost always want a dedicated jab saw due to its stiffer blade and specialized tip geometry designed for starting the initial hole.

• Decision rule: Choose the jab saw for drywall and plaster, and reserve a keyhole saw for detailed woodworking or trim work.

Making a Clean Patch After Your Cable is Installed

If you accidentally make your hole too large or need to relocate a cable, patching the wall correctly is essential for maintaining the home’s aesthetics. Use a “backing” piece of plywood or a small scrap of wood inserted into the hole to provide a sturdy base for your drywall patch.

Secure the patch with drywall screws, apply paper or mesh tape over the seams, and cover with joint compound. Sand the area until smooth, prime, and paint to ensure the repair disappears completely into the wall surface.

• Bottom line: A clean patch depends on securing the patch piece firmly before applying compound, ensuring the repair does not sag or crack over time.

By selecting the right saw for your specific project and following careful cutting procedures, routing cables becomes a manageable task rather than a daunting chore. Keep your tools sharp, verify what lies behind the wall, and your home will be perfectly connected in no time.
