Craftsman 90016496 drill Parts

For the Craftsman 90016496 drill/driver, the core parts you need to operate it are the power unit, variable-speed trigger, forward/reverse slider, drill attachment with keyless chuck, and a charged battery pack (plus the charger). Bits are the main “consumable” you swap based on the job.

Core parts and what they do

• Power unit (motor and controls): houses the trigger and direction control
• Variable-speed trigger: turns the drill on/off and controls speed
• Forward/reverse slider: changes rotation direction; center position locks the tool
• Drill attachment and keyless chuck: holds the drill bit or driver bit securely
• Torque adjustment collar: helps prevent overdriving screws by limiting torque
• Battery pack and battery release button: powers the tool and lets you remove the pack
• Battery charger: recharges the battery pack

Common “extras” most people also need

These are not built-in parts, but they are typically required for real-world use:

• Drill bits (wood, metal, masonry)
• Driver bits (Phillips, Torx, square, hex)
• Bit holder or on-board bit storage (this model includes a bit holder area)
• Safety glasses and hearing protection

Quick reference: parts vs. accessories

Item	Type	Why you need it
Keyless chuck	Drill part	Clamps the bit so it does not slip
Forward/reverse slider	Drill part	Drives screws in or backs them out
Battery pack + charger	Drill part/system	Provides portable power
Drill/driver bits	Accessory	Matches the fastener or material

Why it matters

Using the right core parts (especially a properly tightened keyless chuck and the correct torque setting) helps prevent bit slippage, stripped screws, and drill stalling. For safe operation, we also recommend locking the tool (slider centered) before changing bits.

Helpful operating tips from the manual

• Lock the tool by setting the forward/reverse slider to the center position before installing or removing a bit.
• Tighten the keyless chuck firmly after inserting the bit fully.
• If the drill stalls, release the trigger immediately and correct the cause before restarting.

To replace the drill bit on your Craftsman 90016496 drill/driver, lock the trigger by setting the forward/reverse slider to the center position, open the keyless chuck by hand, insert the bit fully, then hand-tighten the chuck securely (do not use the trigger to tighten).

Steps to change the bit (keyless chuck)

• Remove the battery pack (best practice before adjustments).
• Set the forward/reverse slider to the center (lock) position.
• Hold the rear half of the chuck with one hand.
• Rotate the front half of the chuck to open it.
• Insert the drill bit (or driver bit) fully into the chuck.
• Hold the rear half again and rotate the front half the opposite direction to tighten securely.

Important safety notes

• Do not tighten or loosen the chuck by gripping it and running the drill; this can damage the chuck and cause injury.
• Expect twisting if the drill stalls; grip the drill firmly with both hands.
• If the drill stalls, release the trigger immediately and correct the cause before restarting.
• Before drilling into walls, floors, or ceilings, check for wiring and pipes.

Quick reference: tighten vs. loosen

What you want to do	What to turn by hand	What you should avoid
Loosen chuck (remove bit)	Rotate the front half to open the jaws	Using the trigger to “spin” the chuck loose
Tighten chuck (install bit)	Rotate the front half to clamp the bit securely	“Bumping” the trigger to tighten

Why it matters

A properly tightened bit reduces wobble, slipping, and stalling. It also protects the keyless chuck from premature wear and helps you drill straighter in wood, metal, and plastics.

To unlock your Craftsman 90016496 drill/driver, set the forward/reverse slider to the center (lock) position, then loosen the keyless chuck by twisting the front half in the loosen direction; tighten it again to secure the bit. See the 90016496 owner's manual for the exact control locations.

Quick unlock steps (keyless chuck)

• Remove the battery pack before adjusting the chuck.
• Set the forward/reverse slider to the center position to lock the trigger.
• Hold the rear half of the chuck with one hand.
• Twist the front half of the chuck to open/loosen the jaws.
• Insert the drill bit or screwdriver bit fully.
• Twist the chuck to tighten until the bit is secure.

If the drill feels “stuck” or will not turn

These checks fix most lockup complaints on a drill/driver attachment:

• Forward/reverse slider is centered: the trigger is locked in the center position.
• Chuck overtightened: loosen the chuck by hand; do not use the motor to break it free.
• Bit not seated: reinsert the bit fully, then retighten.
• Tool stalled under load: release the trigger immediately, back the bit out, then restart.
• Battery not fully seated: remove and reinstall the battery pack firmly.

What to twist and which way

Direction can feel reversed depending on how you are holding the tool. Use this as a reference.

What you are doing	What you hold	What you twist	Result
Loosen/open chuck	Rear half	Front half toward “open”	Bit releases
Tighten/close chuck	Rear half	Front half toward “tighten”	Bit locks in
Lock trigger	Forward/reverse slider	Move to center	Trigger won’t run

Why it matters

Unlocking the trigger and loosening the chuck the right way prevents chuck damage and helps avoid sudden twisting if the drill stalls under load.

What you will typically replace on a drill/driver

For a 20V Max power unit and drill attachment like the Craftsman 90016496, the most common replacement needs are wear items and electrical controls.

Symptom	Common part area to check	What to look for
Won’t run	Trigger switch, wiring, battery contacts	Loose/burned terminals, broken wires
Runs but no torque	Gearcase/clutch, chuck	Slipping clutch, damaged gears
Intermittent power	Battery connection points, internal leads	Corrosion, pinched wires
Charger issues	Charger, battery pack	Wrong battery type, dirty contacts

Safety and compatibility notes (battery and charger)

This model uses a 20V Max (18V nominal) battery system; use only designated Craftsman rechargeable batteries and the compatible charger listed for the tool.

• Unplug the charger before inspecting or cleaning it
• Keep metal debris away from charger cavities and battery terminals
• Do not use non-designated batteries or chargers
• Charge and store batteries in moderate temperatures (avoid extreme heat/cold)

Why it matters

Power tool parts are often version-specific; ordering by model 90016496 and confirming against the manual reduces returns and prevents electrical mismatch issues (especially with batteries, chargers, and wiring).
