Craftsman 315111371 cordless screwdriver Parts

A “power screwdriver” is most commonly called a cordless screwdriver or electric screwdriver. Some models are also described as a drill/driver when they can both drive screws and drill holes; the Craftsman 315111371 is a 3.6V cordless screwdriver designed primarily for screwdriving.

Common names you will see

• Cordless screwdriver

• Power screwdriver
• Screwdriver/nutdriver (when used with nutdriver bits)
• Drill/driver (typically higher-voltage tools with a drill chuck)

How to tell if it is a drill/driver or a screwdriver

A quick way to classify the tool is by the bit holder and torque control.

Feature	Cordless screwdriver (like Craftsman 315111371)	Drill/driver (typical)

Voltage	Often 3.6V to 8V	Often 12V to 20V
Torque control	Multi-position clutch	Clutch plus drill mode
Best use	Driving screws, light assembly	Drilling and heavier fastening

You can buy replacement parts for your Craftsman cordless screwdriver model 315111371 through Sears PartsDirect by using the model-based parts list and diagrams to match the exact component you need. For model-specific part identification and safe servicing guidance, use the owner's manual.

The best way to get the right part for model 315111371

The operator’s manual calls out that you should always reference the model number when ordering repair parts, and it lists the primary serviceable items for this tool.

• Confirm the model number on the plate attached to the motor housing (should read 315111371)
• Use the parts list to identify the exact item name before ordering
• Match the part to your symptom (no charge, weak power, won’t run, etc.)
• Replace only customer-serviceable parts; keep internal repairs for a qualified technician
• Use only identical Craftsman replacement parts for safe fit and function

Parts commonly referenced for this model

Based on the manual’s parts list for the Craftsman 315111371 3.6V cordless screwdriver, these are the items typically ordered:

Part description	What it does	When you replace it
Charging stand	Holds the tool for charging	Stand is cracked, loose, or won’t hold contact
Charger	Supplies power to charge the batteries	No charging, intermittent charging, damaged cord
Operator’s manual	Specs, safety, parts list	Missing manual or need diagrams/instructions

Why it matters

Cordless screwdriver charging problems are often caused by the charger, charging stand contacts, or damaged wiring. Ordering by model number helps you avoid mismatched electrical parts and reduces repeat failures.

On the Craftsman 315111371 cordless screwdriver, the bit is held in the collet (not a drill-style chuck). To release it, pull the 1/4-inch hex bit straight out of the collet; if it is stuck, gently wiggle while pulling, then reinsert fully until it seats.

Quick steps to remove the bit

• Turn the screwdriver switch to OFF and keep your finger off the trigger/switch
• If you were using the built-in light, switch it OFF as well
• Grip the bit close to the collet
• Pull the bit straight out; do not twist hard enough to bend the bit
• If it is tight, wiggle slightly while pulling, then inspect the bit shank for burrs

If the bit will not come out

A stuck bit is usually caused by debris, a slightly mushroomed bit shank, or the bit not being fully seated previously.

• Remove the battery power by keeping the tool switched OFF and do not attempt removal while driving
• Check for rust, drywall dust, or metal shavings around the collet opening
• Try a different 1/4-inch hex bit to confirm the collet is not binding
• If the bit shank is damaged, replace the bit (a damaged shank can keep sticking)

What type of bit does this model use?

The 315111371 collet is designed to accept 1/4 in. hex bits.

Item	What to use	What to avoid
Bit type	1/4-inch hex screwdriver bits	Round-shank drill bits
Insertion	Push in as far as possible	Leaving the bit partially seated
Removal	Pull straight out	Prying sideways against the collet

Why it matters

Pulling the bit out straight protects the collet from spreading or cracking and helps the bit seat fully next time, which reduces cam-out and stripped screw heads.

For diagrams and the exact control locations (switch, light, collet), use the owner's manual.

An 11 in 1 screwdriver is a multi-bit hand screwdriver that combines several common driver tips (and often nut drivers) into one tool, usually by storing reversible bits in the handle. It is different from the Craftsman 315111371 cordless screwdriver, which is a 3.6V powered driver with forward/reverse and an adjustable torque clutch (details in the owner's manual).

What “11 in 1” usually includes

Most 11 in 1 screwdrivers are built around a single handle and a multi-bit shaft; the “11” refers to the number of usable tips/ends.

Commonly included:

• Phillips and slotted (flat) driver sizes
• Square (Robertson) drive tips
• Torx tips on some versions
• Nut driver sizes (often 1/4 in. and 5/16 in.)
• Reversible, double-ended bits stored in the handle

How it compares to your Craftsman 315111371 cordless screwdriver

Your Craftsman 315111371 is a powered screwdriver designed for driving and removing screws with a motor and clutch control.

Feature	11 in 1 screwdriver (hand tool)	Craftsman 315111371 (powered)
Power source	Hand force	3.6V DC motor
Direction control	Flip bit or reposition	Rocker switch forward/reverse
Torque control	Your wrist	Adjustable torque clutch (22 settings)
Speed	Manual	Single speed, about 180 RPM no-load

Why it matters

If you need versatility in a tool pouch for mixed fasteners, an 11 in 1 screwdriver reduces the number of separate drivers you carry. If you need faster screw driving with less hand strain, your Craftsman cordless screwdriver is the better fit, especially when you set the clutch to help avoid stripping screw heads.

Quick tips for choosing the right tool

• Use an 11 in 1 for light-duty work, tight spaces, and quick bit changes
• Use the 315111371 for repetitive driving, longer screws, and controlled clutch settings
• Match the bit type to the screw head to prevent cam-out and premature bit wear
• For electrical or wiring-related DIY, follow safe practices and reference the owner's manual for tool operation and warnings

For the Craftsman cordless screwdriver model 315111371, a good torque is the lowest clutch setting that consistently seats the screw flush without stripping the head or damaging the material. This model has a 22-position adjustable torque clutch, so you set torque by results rather than chasing one universal number; see the 315111371 owner's manual.

Recommended way to set torque (fast and accurate)

Use a scrap piece of the same material and dial in the clutch:

• Start on a low clutch number
• Drive a test screw until it stops
• Increase 1 to 2 clicks and repeat
• Stop increasing as soon as the screw seats flush reliably
• If the bit slips in the screw head, switch to a fresh bit before raising torque

Practical starting points (then fine-tune)

These ranges get you close for most cordless screwdrivers with a multi-position clutch.

Task	Starting clutch range	What you are trying to prevent
Small screws, plastics	1 to 5	Stripping, cracking
Furniture assembly, light fastening	6 to 12	Overdriving, cam-out
Larger screws in softwood	10 to 18	Snapped screws, stripped heads
Dense wood or stubborn fasteners	15 to 22	Broken screws, damaged workpiece

Model-specific notes for 315111371

From the operator guidance for this model:

• The clutch has 22 positions for torque control
• Higher torque than needed can damage or break screws
• The tool ships with the clutch set to the lowest torque setting

Why it matters

Correct torque protects screw heads, threads, and the workpiece. On a clutch-equipped Craftsman screwdriver, the clutch slipping at the right point also reduces bit cam-out and helps you avoid overdriving.
