The DCD998 sports DEWALT’s tried and true molded rubber anti-vibration grip. 3 LEDs with 20-second delay after trigger release.One-handed loading 1/4″ hex chuck with easy grip sleeve, accepts 1″ bit tips.Provides 1,825 in-lb of max torque at 0-3,250 rpm and 0-3,800 impacts per minute.Precision drive in speed 1 for precision applications and added control.3-speed settings for optimized application versatility.Compact size (5.3-in front-to-back length) and lightweight (3.4-lbs) design for working in confined spaces.DEWALT-built high power, high-efficiency Brushless motor.0-38,250 BPM for fast drilling in masonry materials.3-mode LED with spotlight mode and 20-min auto shut off.3-speed, high-performance, all-metal transmission.Heavy-duty 1/2-in ratcheting nitro-carburized metal chuck with carbide inserts.It’s also worth noting that the Power Detect design is only built into the DCD998 ½” Hammer Drill/Driver and not the DCB118 ¼” impact driver. Simply put, the electronics inside the DCD998 can detect when the tool is running off of a high-capacity 20V XR battery and the tool can use the full 20 Volts of power during continuous vs. It’s not just a bigger number they put on the spec sheet (DEWALT advertises 29% more power) but power that translated directly into our job site tasks.
So then what’s the biggest upgrade DEWALT included in the DCD998? Power! Or more specifically, DEWALT’s new Power Detect Technology. The new and improved DEWALT Hammer Drill/Driver still has many of our favorite features built into the earlier DCD996 Hammer Drill Driver. The DEWALT 20V ½” Hammer Drill/Driver and ¼” Impact Driver, Model DCK299D1W1, includesĭEWALT ½ Hammer Drill/Driver (DCD998) and ¼ Impact Driver (DCB118) Specifications
This gave us a good feel for the overall performance and design for both tools. We used them for common tasks like driving screws, drilling electrical pass through stud holes, driving lag bolts, and drilling pilot holes in concrete for anchor bolts. As all professionals can attest to, the hammer drill/driver and impact driver are at the top of the list for the most useful and used tools on the job site. When Lowe’s recently asked us to test out DEWALT’s 20V Hammer Drill/Driver & Combo Kit (Model DCK299D1W1), we were excited to put them through the paces on the job site.
