The Makita SP6000 and Bosch GKT18V-20 solve the same problem: making straight, splinter-controlled cuts with a track saw. The major difference is not cutting quality. It is how you supply power. The Makita is a corded saw with steady output and no battery limit; the Bosch is an 18V cordless saw that is easier to set up on a jobsite and more convenient for short work.
For cutting sheet goods in a workshop, the Makita remains the simpler value. For installation work, remodeling, and jobs where dragging a cord is more annoying than changing batteries, the Bosch makes a stronger case. Your existing battery platform should be a major part of the decision.

Makita SP6000 vs Bosch GKT18V-20 specifications
| Feature | Makita SP6000 | Bosch GKT18V-20 |
|---|---|---|
| Power source | Corded, 12 amp | 18V cordless battery |
| Blade size | 6-1/2 inches | 165 mm, approximately 6-1/2 inches |
| Maximum cut at 90 degrees | About 2-3/16 inches | About 2-1/4 inches, depending on configuration |
| Bevel range | Approximately -1 to 48 degrees | Up to approximately 47 degrees |
| Speed control | Variable speed, roughly 2,000 to 5,200 rpm | Electronic speed control, roughly 2,800 to 5,500 rpm |
| Best fit | Workshop cutting and repeated sheet breakdown | Mobile installation and cordless jobsite work |
Exact cutting depth varies slightly with the blade, track, and bevel setting, so treat the numbers as practical specifications rather than permission to cut through any material. Both saws are intended for track-saw work, not for replacing a heavy-duty table saw on thick hardwood production.
Cutting performance and control
The SP6000 has a well-established reputation for predictable plunging and clean cuts. Its 12-amp motor does not run down as the cut continues, which matters when breaking down several sheets of 3/4-inch plywood or laminated panels. The variable-speed dial also lets you slow the blade for plastics and delicate laminates. The saw’s anti-tip and bevel controls are useful, although setup needs to be checked carefully when cutting at an angle.
The Bosch GKT18V-20 is capable of the same kind of clean, splinter-controlled work when paired with a sharp, appropriate blade and a properly set track. Its brushless motor delivers good power for plywood, MDF, countertops, and cabinet panels. However, cordless output is more dependent on battery condition, temperature, and material thickness. A nearly empty battery can turn a confident plunge into a slow, hot cut.
Neither saw eliminates tear-out by itself. Use the correct fine-tooth blade, keep the track’s splinter strip in good condition, and support the offcut. On a narrow offcut, unsupported material can pinch the blade after the cut passes the track. That can cause a kickback even though both saws include safety features intended to reduce the risk.
Corded reliability versus cordless convenience
The Makita’s cord is its main disadvantage. You need an outlet, an extension cord, and enough slack to keep the cord behind the saw. If the cord crosses the track or gets caught under a panel, it can pull the saw off line or interrupt the cut. This is especially irritating when working on a roof, in a finished room, or around insulation and framing.
The Bosch avoids those problems entirely. There is no extension cord to protect, and setup is faster when making a few cuts at different locations. The cost is battery weight and runtime. A high-capacity 18V battery makes the saw more useful, but it also adds weight at the rear of the tool. Long cuts in thick material can consume a noticeable portion of a pack, so serious users should have at least two charged batteries.
If you already own compatible Bosch 18V batteries and chargers, the GKT18V-20 can be the cheaper overall purchase despite a higher bare-tool price. If you do not own the platform, budget for a battery and charger before comparing prices with the corded Makita. Browse Bosch 18V battery and charger kits when calculating the real cost.
Tracks, blades, and accessories
A track saw is only as accurate as its track setup. Check which guide rail is included, because some packages contain the saw only. The Bosch uses Bosch FSN-style guide rails, while Makita SP6000 packages commonly use Makita guide rails. Rail lengths are not automatically interchangeable, even when the saws appear similar. Adapters exist, but they add another adjustment point and can introduce play.
For full plywood sheets, a 55-inch or longer track is much more convenient than joining short rails. When joining tracks, use the manufacturer’s connectors and place the assembly on a flat panel before tightening. A slight bend or step at the joint can show up as a visible error across a cabinet side.
Keep a spare blade available. A blade that is dull, loaded with adhesive, or missing teeth will require more force and can leave burn marks. For general plywood and cabinet work, look for a track-saw blade with around 48 to 56 teeth. A coarse blade may cut faster but usually leaves a rougher edge; a very fine blade can cut cleanly but feeds more slowly and loads up in thick material. See 165 mm track-saw blades for replacement options.
Which saw should you buy?
Choose the Makita SP6000 if you primarily work in a shop, regularly break down multiple sheets, or want consistent power without buying batteries. It is also the sensible choice when the cord will not interfere with the work. The cheaper corded option is fine for occasional cabinet building and DIY projects; spending more for cordless convenience will not make a straight cut straighter.
Choose the Bosch GKT18V-20 if you install cabinets, work in occupied buildings, move between rooms, or already use Bosch 18V tools. Its cordless operation reduces setup time and removes one common failure mode: the cord catching on the panel or track. Just plan for battery rotation and accept that maximum productivity may require a second pack.
For either saw, measure from the track edge to the blade before making the first important cut. Clamp or otherwise secure the rail, allow the saw to reach speed before plunging, and keep both hands on the tool through the cut. Those habits matter more than a small difference in motor speed.
