6 Best Snips for Cutting Cable Raceways Pros Rely On

When running cable raceways along metal walls or soffits, the quality of the finish defines the professionalism of the entire installation. A jagged edge on a metallic raceway not only looks subpar but creates a hazardous snag point for wires during the pull. Relying on the right snips ensures that every cut contributes to a seamless, code-compliant finish. Precision tools turn what could be a tedious, frustrating task into a fluid, efficient part of the workflow.

Wiss M3R Aviation Snips: The All-Around Champ

The Wiss M3R is widely recognized as the industry standard for a reason. These snips handle tight radius cuts and straight lines with equal capability, making them the most versatile tool in a technician’s pouch. When tasked with notched cuts in steel raceway covers, the balanced pivot point provides enough leverage to slice through 22-gauge steel without crushing the profile.

Durability remains the primary draw for pros working on commercial sites. The serrated blades grip the material firmly, preventing the tool from slipping when initiating a cut on a slick surface. If the goal is a singular, do-it-all pair of snips that holds an edge through a long renovation, the M3R is the definitive baseline.

Midwest MWT-6510S Offset Snips: Best for Ergonomics

Offset snips are engineered to keep the user’s hand above the material during the cutting process. This design is critical when navigating long stretches of surface-mount raceway, as it prevents knuckles from scraping against the sharp edges of the metal. The MWT-6510S features a compound leverage action that significantly reduces the manual force required for repeated cuts.

For contractors spending hours mounting runs across expansive ceilings, the mechanical advantage provided by these offsets saves significant wrist fatigue. The handle design accommodates a comfortable grip even when wearing work gloves, ensuring control remains steady throughout the day. Opt for these when the job requires high-volume cutting over extended periods.

Malco M2001 MAX2000 Aviation Snips: Built to Last

Malco has carved out a reputation for producing tools that survive the abuse of a busy job site. The M2001 model utilizes a high-carbon alloy steel construction that resists chipping, even when accidentally clipping a hardened fastener hidden inside a wall cavity. The spring-loaded opening mechanism is consistently smooth, which allows for faster cycling between individual snips.

These snips excel when working with thicker, painted metal raceways where marring the finish is a concern. Because the blades remain tight over years of service, the risk of “folding” the material instead of slicing it is minimized. It is a tool designed for professionals who view their equipment as a long-term investment rather than a disposable item.

Klein Tools 2100-7 Tin Snips: The Electrician’s Pick

Klein Tools remains synonymous with electrical work, and these tin snips are specifically optimized for the materials commonly found in electrical rough-ins. While aviation snips use a compound action for heavy metal, the 2100-7 is a straight-cut shear that offers superior control for trimming thin-gauge raceway lids. They are thin, lightweight, and easily tucked into a back pocket.

The primary benefit here is the ability to make surgical, fine-tuned adjustments to the end of a raceway. When a raceway needs to perfectly butt against a junction box or fit inside a tight corner, the direct-pivot action of these snips provides the tactile feedback necessary for a perfect fit. They are not intended for heavy-duty metal plate work, but they are unmatched for light-gauge finishing.

Ridgid RC-1625 PVC Cutter: For Flawless Plastic Cuts

Not all raceways are made of metal; plastic systems are common in residential settings or moisture-prone environments. Using snips on plastic often leads to splintering or uneven edges, which is where a dedicated ratcheting PVC cutter becomes essential. The RC-1625 produces a clean, square cut on plastic raceways that ensures a professional aesthetic without the need for filing.

The ratcheting mechanism allows for a one-handed operation, which is invaluable when holding a length of plastic conduit against a wall. Because the blade enters the plastic at a controlled rate, the material does not crack or deform under pressure. For any job involving non-metallic systems, this tool is the difference between a clean installation and a sloppy mess.

Bessey D216 Erdi Snips: Best for Precision Work

Bessey tools are often chosen for their superior metallurgy and the longevity of their cutting edges. The D216 Erdi series is designed for those who prioritize precision over brute force. These snips are exceptionally thin, allowing them to fit into tight pockets of raceway profiles that standard-sized aviation snips simply cannot reach.

These are the go-to tools when working on intricate, custom-fitted raceway configurations. The blades are ground to a high tolerance, providing a “scissor-like” cut that minimizes burrs and deformations on the metal. If the project involves custom metalwork or complex turns, the Bessey D216 is the professional’s choice for clean, accurate results.

Straight Left or Right Cut? Choosing Your Snips

Understanding the directional nature of aviation snips is key to avoiding frustration on the job. Right-cut snips are designed to cut curves to the right, while left-cut snips are for curves to the left. Using the wrong snip for a specific direction forces the waste metal to curl into the tool, which binds the blade and ruins the cut line.

Straight-cut snips are the jack-of-all-trades, but they become cumbersome when attempting to navigate around obstructions. Always look at the color of the handles—yellow is typically straight, red is left, and green is right. For most raceway work, keeping one straight-cut and one offset-right pair in the belt will cover ninety percent of the required cuts.

Cutting PVC vs. Metal Raceway: The Right Technique

Mixing up the cutting method for different materials is the fastest way to ruin blades. Metal raceway requires a steady, deliberate motion to keep the shear line clean, while PVC often benefits from the quick, decisive snap of a ratcheting cutter. When cutting metal, ensure the snips are always perpendicular to the material to prevent the metal from bending or creating a dangerous, sharp edge.

Never use metal-cutting aviation snips on thick plastic, as the thickness of the material can stress the pivot point and misalign the blades. Conversely, avoid using plastic cutters on metal; the hardened material will dull the cutting edge of a plastic tool in seconds. Respecting the material-to-tool relationship ensures every tool stays sharp and performs as intended.

How to Get a Clean Burr-Free Cut Every Single Time

A burr is a sharp, jagged edge left behind by a dull blade or an improper cutting angle. To ensure a clean finish, always start the cut at the tip of the snips rather than the back of the jaws. Moving the snips forward through the cut—rather than snapping the handles shut all at once—prevents the metal from tearing at the finish line.

If a burr does occur, do not rely on the snips to clean it up. Keep a small, fine-toothed metal file in the pouch for quick cleanup. A single swipe across the edge after the cut ensures the raceway is safe for wiring and visually consistent with the rest of the run.

Keeping Your Snips Sharp: Maintenance Tips for Pros

Snips are precision instruments that require basic care to maintain their performance. Avoid using them to cut wire or screws, as this will create notches in the blades that carry over into every subsequent cut. If the hinge feels stiff or starts to stick, a drop of light machine oil is all that is required to restore smooth operation.

Should the blades become dull, they can be sharpened with a fine-grit diamond hone, but avoid heavy grinding wheels that can overheat and ruin the temper of the steel. When the blades no longer meet perfectly at the tips, the pivot bolt can sometimes be tightened, though this is often a sign that it is time for a replacement. Well-maintained snips should provide years of service, provided they are treated as tools of precision rather than utility.

Selecting the right pair of snips is not just about brand loyalty, but about matching the tool’s mechanical advantage to the specific material and geometry of the raceway being installed. Whether prioritizing ergonomic comfort for long days on the job or surgical precision for intricate layouts, a professional-grade set of snips remains the most important tool for a clean installation. Consistent results come from understanding these nuances, ensuring that every run is as clean and secure as the day it was installed.
