DEWALT Rotary Saw DW660 Cut-Out Tool - Powerful 5A Motor

In this review the DEWALT Rotary Saw DW660 is presented for tradespeople who need a compact, powerful cut-out tool for drywall and light carpentry tasks. The biggest reason to consider it is the 5.0 amp, 30,000 rpm motor that delivers noticeably more cutting power than many competing cutout tools, while the slim body and ergonomic design reduce fatigue during extended use. The tool-free bit change and dust-sealed switch make it practical on job sites where speed and durability matter.

Key Features

• 5.0 amp, 30,000 rpm motor: Provides strong cutting performance for clean cuts in drywall and similar materials at a fast pace.
• Tool-free bit change: Lets the user swap bits quickly on the fly without a wrench, speeding up repetitive tasks.
• Slim ergonomic body: Reduces hand fatigue during prolonged use, improving control in tight spaces.
• Dust-sealed switch: Protects against dust infiltration to extend switch life on dusty job sites.
• Turn-on/Bump-off switch: Allows easy shutdown of the tool for safer operation and quick stops between cuts.
• Jam-pot construction: Adds durability so the tool tolerates typical jobsite knocks and rough handling.

Who It's For

This tool is aimed at professional drywallers, electricians, and carpenters who need a reliable, high-speed cutout tool for making openings and trimming sheet materials. Its higher-powered 5.0 amp motor is particularly helpful when working through thicker or denser drywall where a weaker motor would bog down.

Home DIYers who only need occasional light trimming may find the power and features more than required and could look at smaller, lower-cost rotary options. If tool-free bit systems or sealed switches are essential, this model brings those pro-oriented features to regular jobsite use.
