Don’t Trash Your Broken DeWalt DCD996: The Ultimate Housing Replacement Guide

Every tradesman knows the sound. You leave your drill balancing on a ladder rung, turn your back for two seconds, and hear that sickening plastic crunch as it hits the concrete floor.

When you pick up your DeWalt DCD996 20V MAX XR Hammer Drill, the heavy metal chuck and brushless motor are usually perfectly fine. But the plastic handle? Split right down the middle, or shattered near the battery rail.

Your first instinct might be to reach for a roll of duct tape or pull out your phone to order a $160+ replacement bare tool. Stop right there. As tool repair technicians, we see this exact break constantly. The smartest move you can make is to keep your perfectly good motor and gearbox, and simply perform a “guts swap” into a Replacement Housing Shell (NA013594).

Here is exactly why re-shelling your drill is the right call, and how to do it without losing your mind.

The Duct Tape Trap: Why a Cracked Shell Kills Your Drill

Let’s kill the “I’ll just tape it up” idea right now. For a heavy-duty brushless drill like the DCD996, a compromised housing is a ticking time bomb.

1. The Dust Invasion: Construction sites are full of conductive concrete and metal dust. The factory DeWalt clamshell is designed to seal the sensitive electronic control board away from debris. A crack bypasses this defense, allowing conductive dust to settle on the trigger board, guaranteeing an expensive short circuit.
2. Airflow Suffocation: Brushless motors rely on precise, internal aerodynamic channels molded into the plastic to pull cooling air over the stator. Taping over cracks and vents traps heat inside. You will literally bake your expensive motor to death under heavy load.
3. Torque Failure: The DCD996 generates a massive amount of torque. When you are driving a long lag bolt, a cracked handle will flex and eventually separate in your hand, which is incredibly dangerous on a ladder.

If the shell is busted, the tool is unsafe.

Repair vs. Replace: Evaluating the Options

When your casing cracks, you basically have three options. Let’s break them down:

• Option A: Buy a New Bare Tool. You spend over $160 to replace a tool where 90% of the internal components are still in perfect working order. This is a massive waste of money.
• Option B: The Epoxy / 3D Print Route. Trying to glue structural, high-impact ABS plastic rarely holds up to job site abuse. 3D printed shells often lack the exact micro-tolerances needed to hold the planetary gears tight.
• Option C: The OEM-Spec “Empty Shell” Swap. You spend a fraction of the cost to buy a precision-molded NA013594 replacement shell. You open the broken drill, lift out the motor, trigger, and gearbox as one connected piece, and drop it into the new plastic.

Option C is the clear winner for anyone who values their paycheck.

Why Precision Molding Matters for the DCD996

If you are going to swap the guts of your drill, you need a high-quality replacement shell. The internal architecture of the DeWalt DCD996 is packed extremely tight.

If the internal screw bosses, the bearing seat for the chuck, or the trigger slide channels are off by even half a millimeter, the drill will vibrate horribly or the two halves simply won’t close. The replacement shells we stock at FixPartHub are engineered from high-impact ABS polymer and feature the exact internal ribbing required for the DCD996 brushless system. Your heavy metal gearbox and stator will lock into place exactly like they did from the factory.

(Note: This is a purely mechanical repair. The kit includes the empty left and right plastic clamshell halves only. You simply reuse your existing screws, motor, and electronics.)

The Pro-Tip for the “Guts Swap”

So, your new NA013594 shell just arrived. You clear off your workbench and grab your Torx screwdrivers.

Before you start ripping components out of the broken shell, follow this one critical rule: Take photos of the wire routing.

DeWalt packs the thick power wires running from the battery terminal to the motor incredibly tight. Every single wire has a designated groove. When you open your broken drill, take three clear, well-lit photos of exactly how those wires are tucked into the plastic channels.

When you drop the motor into your new FixPartHub shell, those wires must go back into their exact factory channels. If a wire is sitting even slightly too high, you will pinch and cut it when you screw the two new casing halves together. Route the wires perfectly matching your photos, and the new shell will close up seamlessly.

Fix It Right, Get Back to Work

Downtime costs you money, but throwing away a perfectly good brushless motor is just burning cash. By taking 20 minutes at your workbench to transfer your drill’s internals into a fresh, structurally sound DeWalt DCD996 Replacement Housing Shell, you restore the safety, airflow, and rigid grip of your heavy-duty drill.

Grab your exact-fit replacement shell from FixPartHub today, and get that workhorse back on the job site.
