DDF491 Installation Driver Initial Impressions
First impressions of the Makita DDF491: handling, interchangeable heads, build quality, and the appeal of a 13 mm chuck.
Published
The Makita DDF491 makes a good first impression in hand. The interchangeable heads are convenient, the build feels solid, and the 13 mm chuck is a welcome step up from my older DF330D.
Weight and balance
With the quick-change collet attached, the DDF491 feels roughly the same weight as my TD173 impact driver, perhaps slightly heavier when held upright. Held sideways, it feels noticeably more top-heavy than the TD173. With a battery attached, though, the weight distribution feels well-balanced.
Attachments and build quality
The quick-change collet allows for quick bit insertion, similar to the TD173.
The keyless chuck attachment appears to be made of metal and feels solid and well-built. Makita specifies a metal single-sleeve chuck. The plastics, materials, and overall build quality also feel good in hand, consistent with what I expect from other Makita tools.
Why the 13 mm chuck matters
The DDF491 has a 13 mm chuck, compared with the 10 mm chuck on the Bosch GSR 12V-15 FC and the 3/8-inch chuck (commonly described as 10 mm) on the Milwaukee M12 FUEL installation driver, 2505-20.
That extra capacity is particularly useful for bits with larger shanks, including some step drill bits. I own a Makita DF330D, and its 10 mm chuck is easily my biggest gripe with it.
More than an installation driver
Makita rates the DDF491 at a maximum torque of 65 Nm, with hard/soft fastening torque of 50/27 Nm, compared with Bosch’s 30 Nm and Milwaukee’s approximately 34 Nm ratings. The Makita appears substantially more powerful on paper, making it a capable general-purpose drill rather than merely an installation driver.
Storage
For Packout users, the DDF491 fits into a 3-drawer Packout, making it easy to store alongside your other tools and accessories without needing a separate case. Its compact size is particularly convenient for drawer-based storage.
