Craftsman 113213720 8" bench model drill press Parts

Yes. On the Craftsman 113213720 8 inch bench model drill press, you can replace the chuck by removing the existing chuck from its taper (usually a Jacobs taper on the chuck and a Morse taper in the spindle), then cleaning and reseating the new chuck and arbor so it runs true.

Safety first

• Unplug the drill press before touching the chuck, belts, or spindle.
• Remove the bit and lower the table for clearance.
• Wear eye protection; tap-out operations can release parts suddenly.
• Support the chuck with a block of wood so it does not drop.
• Avoid striking the chuck jaws directly; it can ruin accuracy.

How chuck removal usually works (common drill press design)

Most bench drill presses remove the chuck in one of these ways:

What you see	Likely setup	Typical removal method
Slot in the quill/spindle	Tapered arbor seated in spindle	Insert a drift key (wedge) and tap to pop the arbor/chuck out
No slot, but a retaining screw inside chuck	Threaded mount	Open jaws fully, remove screw (often reverse thread), then unthread chuck

Tapered arbor method (most common)

• Lower the quill to expose the slot.
• Insert the correct drift key into the slot.
• Tap the drift key firmly to release the arbor and chuck.

Installing the new chuck (so it stays tight)

• Clean the spindle taper and arbor with solvent; remove oil and dust.
• Inspect for burrs or dents; lightly dress with fine abrasive if needed.
• Seat the arbor into the spindle taper.
• Press the chuck onto the arbor by raising the table and pulling the quill down firmly (no hammering).
• Test runout with a straight bit or rod; re-seat if wobble is obvious.

Why it matters

A worn or poorly seated chuck causes wobble, oversized holes, and bit slippage. A properly installed chuck improves accuracy and reduces vibration, which also helps protect the spindle bearings and belts.

On the Craftsman 113213720 8 inch bench model drill press, spindle repair usually means removing the quill assembly, inspecting the spindle and bearings, then replacing worn bearings or the spindle and reassembling with correct retention and runout checks. This restores smooth rotation and accurate drilling.

Before you start (safety and setup)

• Unplug the drill press; lock out power so it cannot be switched on.
• Remove the bit, chuck key, and any workpiece; lower the table for clearance.
• Mark the depth stop and quill return spring position so reassembly is easier.
• Take photos as you go; small washers and clips must return to the same order.
• Plan to clean and lightly oil sliding surfaces during reassembly.

Spindle and quill repair steps (typical process)

1. Remove the belt cover and release belt tension; slip the belt off the pulleys.
2. Remove the chuck (and arbor if used) from the spindle taper.
3. Support the quill; remove the quill retaining hardware (often a retaining ring or collar).
4. Slide the quill assembly out of the head.
5. Separate the spindle from the quill; press or drive the spindle out carefully.
6. Remove and replace spindle bearings if rough, noisy, loose, or seized.
7. Reinstall bearings on the spindle, reinstall the spindle into the quill, then reinstall the quill.
8. Re-tension the belt, verify smooth quill travel, and check runout at the chuck.

What to inspect while it is apart

Item	What you are looking for	What it causes
Spindle bearings	Grinding, play, heat discoloration	Wobble, noise, poor hole accuracy
Spindle taper	Rust, scoring, dents	Chuck falls off, runout
Quill bore	Galling, debris, wear	Sticky feed, uneven return
Return spring	Weak tension, binding	Quill will not retract

Why it matters

A worn spindle or bearing set is one of the most common reasons a drill press drills oversized holes, chatters, or throws the chuck. Fixing the spindle assembly improves accuracy, reduces vibration, and protects the motor and pulleys.

On the Craftsman drill press model 113213720, the model number is on the identification label at the rear of the head (the motor and pulley housing). Use 113213720 when ordering parts so we match the correct diagrams and components.

Where to look on model 113213720

• Stand behind the drill press and look at the back side of the head
• Check for a metal nameplate or printed decal on the head casting
• Wipe off dust and oil; the printing is often easier to read after cleaning
• If the label is missing, look for small rivet holes or a clean rectangle where it was mounted

What information you should write down

Most Craftsman drill press ID labels include:

• Model number (used for parts lookup)
• Serial number (helps identify the production run)
• Electrical ratings (volts, amps, phase)

Label item	Why it matters for parts and service	Example for this drill press
Model number	Matches the correct parts list and diagrams	113213720
Serial number	Helps narrow variations across production	Varies
Electrical ratings	Confirms correct switch, cord, and motor specs	Varies

Why it matters

Craftsman drill presses can look similar across model series, but parts like the switch, belts, pulleys, and quill components vary by model. Using the exact model number prevents ordering the wrong part.

Craftsman drill presses were built for Sears by several different manufacturers over the years, so there is no single company that made them all. For Craftsman model 113213720, the most accurate way to identify the original maker is to use the data plate and any manufacturer codes on the drill press and motor.

Common makers you may see on older Craftsman drill presses

Depending on the era, Craftsman drill presses are commonly associated with manufacturers such as:

• King-Seeley
• Emerson Electric
• Atlas Press Company
• Walker-Turner
• Other later suppliers (varies by production run and year)

How to identify the maker on model 113213720

Use the physical identification tags first; they are more reliable than assumptions based on the model prefix.

• Check the data plate on the head, column, or base for a listed company name
• Look for an EIA code, date code, or manufacturer code on the plate (if present)
• Check the motor nameplate for the motor manufacturer (this can differ from the drill press maker)
• Note any casting marks inside the pulley cover or on the head casting
• When buying replacement parts, always match by model 113213720 to ensure fit

Quick reference: what different tags tell you

Where you look	What it identifies	Why it matters
Drill press data plate	Tool maker or Sears production info	Best clue to who built the machine
Motor nameplate	Motor manufacturer	Helps when replacing motor or electrical components
Casting marks	Foundry or casting run	Useful for confirming families of designs

Why it matters

Knowing the actual maker helps you match the correct quill/spindle parts, belts and pulleys, switches, and bearings because similar-looking Craftsman bench drill presses can use different shaft sizes and mounting patterns.
