Choosing Power Tools by Job: Saw, Grinder, Ratchet Wrench, or Driver Drill

A practical guide to four power tools with listed prices from USD 19.88 to USD 118.99, matching each pick to cutting, grinding, fastening, or drilling needs.

Last updated Jul 23, 2026

Buying power tools gets easier when you start with the job instead of the brand or the price. A circular saw, angle grinder, cordless ratchet wrench, and driver drill all belong in the same broad workshop conversation, but they solve very different problems. The right choice depends on whether you need to cut wood, grind metal, work in tight mechanical spaces, or drill and drive fasteners.

Quick take

  • For wood-cutting projects: The For Milwaukee M18 Battery 18V Cordless Circular Saw - 6-1/2\" - Bare Tool is the clear match, with wood cutting called out and a bare-tool setup for shoppers already thinking in battery platforms.
  • For grinding work: The DEWALT DCG408B 4 1/2\" Paddle Switch Angle Grinder is the dedicated grinder in this group and sits at the top of the listed price range.
  • For automotive and mechanical fastening: The DEWALT DCF512 20V Brushless Cordless Ratchet Wrench LED Tool is aimed at ratchet-wrench tasks, with an LED work light and compact-head wording that fits tight work areas.
  • For drilling and screw driving: The Makita DDF487 18V Brushless Cordless Driver Drill Electric Drill Tool Only is the most direct fit for general drilling and fastening around a home, workshop, or job site.

Listed price comparison

The four tools span from USD 19.88 to USD 118.99, so the lowest listed price is 83% below the highest. That spread matters, but it should not be the only deciding factor because each tool type is built around a different task.

Concise product notes

For Milwaukee M18 Battery 18V Cordless Circular Saw - 6-1/2\" - Bare Tool

This is the pick for shoppers whose next project centers on wood cutting rather than fastening or grinding. The title and description point to a cordless circular saw format, and the details include a 20mm arbor, left blade location, 6-1/2 inch blade diameter, and bevel adjustment up to 45 degrees. The strongest reason to choose it is the specific cutting role: framing, deck work, renovation tasks, and sheet goods are all a better fit for a circular saw than for the other tools here. The limitation is equally clear: it is a bare tool, with no battery, charger, or blade included, so it is not a complete ready-to-cut package by itself.

DEWALT DCG408B 4 1/2\" Paddle Switch Angle Grinder

The DEWALT DCG408B is the most focused choice here for grinding work. Its title names a paddle switch angle grinder, and the description ties it to 20V MAX XR, brushless angle grinder, cordless metal grinder, 4.5 inch grinder, and 5 inch grinder wording. Choose it when the task is shaping, grinding, or metal-work prep rather than drilling holes or driving screws. It also carries the highest listed price in the group, so it makes the most sense when the grinder format is the tool you actually need. A limitation is condition: it is marked open box, while several other tools in the comparison are marked new.

DEWALT DCF512 20V Brushless Cordless Ratchet Wrench LED Tool

This DEWALT ratchet wrench is aimed at fastening jobs where a drill driver is not the ideal shape. The description highlights a brushless motor, integrated LED work light, variable speed trigger, ergonomic soft-grip handle, and a compact head for tight spaces. That makes it a practical match for automotive repairs, garage work, workshop use, mechanical maintenance, and equipment servicing. The concrete reason to choose it is access: the ratchet-wrench shape and LED work light are better aligned with tight, low-light fastening than a circular saw or angle grinder. The tradeoff is that it is tool only, and the attributes state battery included: no.

Makita DDF487 18V Brushless Cordless Driver Drill Electric Drill Tool Only

The Makita DDF487 is the general-purpose drilling and fastening option in this set. It is described as an 18V brushless cordless driver drill with a compact and lightweight design, keyless chuck, ergonomic grip, and suitability for drilling and screw driving around the home, workshop, or job site. Pick it if your priority is everyday holes and fasteners rather than cutting boards or grinding metal. It also sits well below the top of the price range while still offering a named driver-drill role. The limitation is in the package wording: it is tool only, and the attributes list battery included: no, so it is not a full battery-and-charger kit.

How to choose among them

Start with the motion the job requires. If the work involves separating wood stock, a circular saw is the closest match. If it involves abrasive work on metal, the angle grinder is the dedicated tool. If you are turning fasteners in engine bays, equipment, or tight workshop areas, the ratchet wrench shape is the more relevant option. If you need a common household and workshop tool for drilling and screw driving, the driver drill is the more versatile everyday format.

Next, think about battery expectations. Several tools here are explicitly tool-only or battery-not-included, so their appeal is strongest when you already plan around a compatible battery platform. The circular saw is described around Milwaukee M18 battery compatibility, while the DEWALT ratchet wrench is described around a DCF512 20V battery platform. The Makita driver drill is described as an 18V battery-powered tool. Those platform cues may matter more than the up-front price if you are trying to avoid adding another battery system to your workspace.

Finally, weigh condition and role against price. The DEWALT angle grinder is the highest priced option and is marked open box, but it is also the only dedicated grinder. The circular saw is the lowest priced option, but it lacks battery, charger, and blade. The Makita driver drill offers the broadest everyday drilling-and-fastening role, while the DEWALT ratchet wrench is more specialized for mechanical fastening.

Final recommendation

For most shoppers who simply need one practical power tool for common drilling and screw-driving tasks, the Makita DDF487 18V Brushless Cordless Driver Drill Electric Drill Tool Only is the easiest all-around recommendation because its role is broad and its listed price is USD 39.99. If your project is specifically wood cutting, choose the For Milwaukee M18 Battery 18V Cordless Circular Saw - 6-1/2\" - Bare Tool instead, especially if the bare-tool format fits your setup. For grinding, the DEWALT DCG408B 4 1/2\" Paddle Switch Angle Grinder is the right tool type despite being the highest priced. For tight mechanical fastening, the DEWALT DCF512 20V Brushless Cordless Ratchet Wrench LED Tool is the better match because of its ratchet-wrench format and LED work light.
