A corded option for substantial rough cuts near suitable power
Shortlist the RS428 when vibration-control design matters to the setup
The Bosch RS428 is a current corded reciprocating saw to compare for rough cutting around a powered workshop or renovation station. Its vibration-control system and Constant Response circuitry are useful design features, while the variable trigger lets you control the cut start.
Choose it around the complete setup rather than the 14-amp label alone. Check access, appropriate blades and mains provision. Compare the DeWalt DWE305 if its four-position blade clamp is more relevant to the cuts you need.
The RS428 is a 14-amp corded rough-cutting saw. It is a different model from the RS7 formerly reviewed on this page, with its own dimensions, controls and instructions. The exact RS7 Amazon offer was unavailable at our October 2026 check; the RS428 was available new from Amazon.com.
This update provides a researched buying alternative without claiming a direct successor relationship or a verified manufacturer discontinuation. The sections below explain what the RS428 features mean for choosing blades, supporting the work and managing a corded station.
Good reasons to consider it
- No saw battery or charger purchase
- Vibration-control handle and counterbalance design
- Variable trigger and speed-maintenance circuitry
What to weigh before buying
- Cord routing and suitable mains provision are required
- Full-size package can be awkward in restricted access
- Manufacturer vibration claims are not independent results here
RS428 vs. DWE305: control design or blade orientation?
Swipe the table sideways on a phone.
| Product and buying link | Choose for | Key distinction | Check before buying |
|---|---|---|---|
| Bosch RS428 | Full-size rough cutting near suitable mains power | 14 amp with vibration control and Constant Response | 8.65-lb listed weight; confirm access and power arrangement |
| DeWalt DWE305 12-amp corded saw | Suitable rough cuts where blade orientation matters | Four-position keyless clamp; 1-1/8-inch stroke; up to 2,900 SPM | Verify work clearance, grip and current seller package |
The RS428 is worth comparing for its vibration-control and speed-maintenance design. The DWE305 provides a different blade-access feature set with its four-position clamp. Neither choice is a universal winner from amp rating alone.
DeWalt DWE305 12-amp corded saw: Suitable rough cuts where blade orientation matters
Compare the DWE305 when the four-position clamp addresses a real access need. It uses a different documented stroke and controls, but the specification differences alone do not tell us which completes your cut faster. Include the correct blades and cord arrangement in either purchase.
Who should compare the RS428?
The RS428 is worth considering for rough cutting when you can provide suitable power and support the work securely. A workshop cleanup project, a localized renovation and repeated material breakdown can all make a corded saw relevant. The important condition is that the cutting station can safely accommodate the tool and its lead.
For scattered cuts far from an outlet, compare a cordless arrangement instead. For a cramped repair where the full-size body cannot be positioned well, compare a compact format. A larger amp number does not solve access or tell you how clean the finished edge will be. Choose the tool around the material, finish requirement and space to work.
Vibration control is a design feature, not a zero-vibration promise
Bosch documents a counterbalance system and anti-vibration handle. Those features make the RS428 relevant when handling comfort is part of the purchase decision. This review has not measured vibration, so it does not promise a particular reduction for your material, blade or grip.
The blade and workholding still matter. A dull blade, unsupported pipe or a cut that pinches the blade can make operation harder regardless of the handle design. Maintain proper shoe contact where instructed, support the work and avoid excessive pressure. Plan breaks and handling around the actual task rather than assuming a vibration-control feature removes fatigue or makes prolonged use automatically comfortable.
Constant Response and the variable trigger
Constant Response circuitry is intended to maintain the desired speed under load. The variable trigger lets you start gradually and adjust speed to the material and blade. These are useful controls, but neither guarantees that the fastest setting is best for every cut.
Begin according to the manual and blade guidance, establish the cut and increase speed as appropriate. Thin metal and plastic need a different approach from rough lumber. If progress slows, inspect blade suitability and support rather than forcing the motor. A maximum strokes-per-minute figure is a specification, not an independent measure of job completion time. This article does not make a measured cutting-speed claim.
The 1-1/8-inch stroke needs blade clearance
Stroke is how far the blade travels, not the maximum thickness you can cut. Choose enough blade length to remain beyond the material through its full movement. A short blade can catch inside the work; a long flexible blade can reach obstacles behind it or wander during the cut.
Select tooth design for the actual material. Use a blade intended for embedded nails when they are possible, and a suitable metal blade for the specific thickness of pipe or sheet. The included wood-with-nails blade is a starting accessory rather than a complete solution for all materials. Keep a small task-specific blade selection instead of expecting the motor to compensate for the wrong teeth.
Plan the power lead before planning the cut
The RS428 needs suitable 120V mains provision. If an extension is required, select it according to the manual’s electrical requirements, length and conditions. A lead that physically reaches the station is not necessarily the correct lead for the tool. Check damaged insulation and connections before use.
Route the cord away from the blade, falling offcuts and walking paths. Keep the work supported so it cannot pull or pinch the lead as it moves. For work in unsuitable conditions, stop and resolve the station rather than improvising a power arrangement. Corded power removes battery charging from the saw purchase, but it adds routing and supply decisions that belong in the budget and setup.
Weight, package and care complete the buying decision
Bosch lists the tool at 8.65 lb and 18.4 inches long. Consider whether you can position and control that package at the actual cut, particularly when the work is awkward to reach. A full-size saw is not automatically the right choice for every overhead or confined task.
The maker lists a wood-with-nails blade and carrying bag with the saw. Check exact seller contents and condition. Follow the prescribed cleaning method with power disconnected, inspect guards and controls, and stop if a clamp or control is damaged. Keep blades protected in storage and replace worn teeth rather than using extra pressure. The appropriate working package includes support and blades as well as the saw body.
Prepare a powered rough-cutting station
Before the first cut
Read the exact operating instructions and inspect the lead, blade, clamp and controls. Isolate power before adjustments. Support the work as prescribed and inspect the cutting area before beginning.
Select the blade for the material and required projection. Use the specified grip and protective equipment, with hands and bystanders outside blade travel.
Keep the lead and work contact controlled
Route the lead outside the cutting and walking paths. Use the manual’s extension requirements where relevant and keep the power arrangement suitable for the work environment.
Follow the prescribed shoe contact and cutting method. Stop if the work moves, the blade binds or behavior changes; investigate before continuing.
After the job
Disconnect power before cleaning or changing the blade. Remove debris using the approved method and inspect for damage. Do not lubricate or alter parts using generic instructions for another reciprocating saw.
Store the saw dry, protect the lead and cover sharp blades. Use the hook only in its documented arrangement, and have damaged electrical equipment serviced appropriately.
RS428 buying questions
Is the RS428 cordless?
No. It is a 120V corded saw. Do not rely on an inconsistent marketplace power-source field for the older RS7.
Is it the same saw as the RS7?
No. The RS428 is a separately identified buying alternative with its own specifications and manual.
Does vibration control eliminate vibration?
No. It is a design feature. Blade, material, support and handling affect operation, and this review has not measured vibration.
Does 14 amp prove it cuts faster than a 12-amp saw?
No. Specifications alone do not establish a head-to-head cutting result. Choose around features and task suitability.
What blade is included?
Bosch lists a wood-with-nails reciprocating blade with the saw. Verify exact seller contents and choose other blades for different materials.
Can it make fine finish cuts?
It is a rough-cutting tool. Use a suitable precision saw for visible joinery or clean straight panel edges.
Choose the RS428 around control, access and power
The RS428 is a relevant corded option when its full-size format, vibration-control design and speed-maintenance circuitry fit the work. Verify the delivered package and prepare suitable blades, support and power provision.
Compare the DWE305 when blade orientation is a more useful feature for your cuts.
