Milwaukee Band Saw: Specifications, Blade Size, and Parts Support

You walk into a tool supplier and ask for a Milwaukee band saw. The counter person asks which one. You say “the cordless one.” They show you four different models. You did not realize Milwaukee made that many. Now you are trying to figure out which one you need based on a vague recollection of what your coworker uses.

Milwaukee has the widest range of cordless and corded band saws in the industry. Understanding the full lineup helps you pick the right saw and find parts when something breaks.

Complete Model Lineup

M12 FUEL Compact Band Saw (2529-20)

• Power: M12 12V battery
• Blade length: 30-9/16 inches
• Cut capacity: 1-5/8 inches
• Blade speed: 350 SFPM
• Weight: 6.4 pounds
• Motor: POWERSTATE brushless
• Battery life: Up to 50 cuts per charge (1/2 inch EMT)

The smallest Milwaukee band saw. Designed for electricians and plumbers who need to cut small conduit and tubing in tight spaces. The 30-9/16 blade is unique to this model.

M18 FUEL Compact Band Saw (2829-20)

• Power: M18 18V battery
• Blade length: 35-3/8 inches
• Cut capacity: 3-1/4 inches
• Blade speed: 550 SFPM
• Weight: 10.2 pounds
• Motor: POWERSTATE brushless
• Battery life: Up to 150 cuts per charge (1-5/8 inch unistrut)

The M18 compact is the middle ground. It handles larger material than the M12 but is lighter and more maneuverable than the deep cut. The 35-3/8 blade is shared with the older corded compact (6230-20).

M18 FUEL Deep Cut Band Saw (2729-20)

• Power: M18 18V battery
• Blade length: 44-7/8 inches
• Cut capacity: 5 by 5 inches
• Blade speed: 380 SFPM
• Weight: 15 pounds
• Motor: POWERSTATE brushless
• Battery life: Up to 78 cuts per charge (1-5/8 inch unistrut)

The flagship. This is the saw most people think of when they hear “Milwaukee band saw.” It cuts the same material as the corded deep cut but runs on batteries. The 44-7/8 blade is the most common portable band saw blade size.

M18 FUEL Deep Cut Dual-Trigger (2729S-20)

Same as 2729-20 but with dual-actuation trigger. Both the top and bottom trigger must be pressed to start the saw. Required on some jobsites for safety compliance.

M18 FUEL Deep Cut (2929-20)

Updated version of the 2729-20. Improved motor with better Constant Power Technology. Slightly lighter. Same blade and cut capacity.

M18 FUEL Deep Cut Dual-Trigger (2929S-20)

Updated dual-trigger version of the 2929-20.

Corded Deep Cut Band Saw (6232-20, 6232-21)

• Power: 120V AC, 11 amp
• Blade length: 44-7/8 inches
• Cut capacity: 4-3/4 by 4-3/4 inches
• Blade speed: 350 SFPM (6232-20), variable speed (6232-21)
• Weight: 16 pounds

The corded version. The 6232-20 is single speed. The 6232-21 has variable speed control. Uses the same 44-7/8 blades as the M18 deep cut.

Corded Compact Band Saw (6230-20)

• Power: 120V AC, 6 amp
• Blade length: 35-3/8 inches
• Cut capacity: 3-1/4 inches
• Blade speed: 350 SFPM
• Weight: 11 pounds

Older corded compact. Uses the same 35-3/8 blades as the M18 compact. Still available but less common than the cordless versions.

Key Technologies

POWERSTATE Brushless Motor: Milwaukee’s proprietary brushless motor. Delivers more power than brushed motors with longer life and no maintenance. Used on all FUEL models.

REDLITHIUM Battery: Milwaukee’s battery platform. M18 batteries range from 2.0 to 12.0 Ah. For band saw use, 5.0 Ah or larger is recommended. Smaller batteries will work but drain quickly under load.

REDLINK PLUS Intelligence: Electronic system that communicates between tool, battery, and charger. Prevents overload, optimizes power delivery, and extends battery life. If the saw detects a jam or overload, it shuts down before damage occurs.

Constant Power Technology (CPT): Maintains blade speed under load. Without CPT, the blade slows when you hit thick material. With CPT, the motor increases power to maintain speed. This produces faster, more consistent cuts.

Cut-Brake: Stops the blade within seconds of releasing the trigger. Reduces the risk of injury from a coasting blade. Standard on newer models.

Parts Support

Milwaukee has excellent parts support. The company maintains an online parts catalog with exploded diagrams for every model. Common wear parts are available:

Blades: Available from Milwaukee, DEWALT, LENOX, MK Morse, and other manufacturers. The 44-7/8 inch size is the most widely available.

Shoe assembly: The adjustable shoe can wear or bend. Replacement is straightforward with basic tools.

Blade guides: Upper and lower guide blocks wear over time. Milwaukee sells replacement guide kits.

Tension knob: The plastic knob on the 2729-20 is a known weak point. The 2929-20 uses a metal-reinforced knob.

LED assembly: The work light LED can fail from vibration. Replacement is a 10-minute job.

Switch assembly: The trigger switch can fail after heavy use. Replacement requires disassembling the handle.

For motor, electronics, or internal components, Milwaukee service centers handle repairs under warranty or for a fee. The POWERSTATE motor is not user-serviceable.

Which Milwaukee Band Saw Should You Buy?

For electricians and plumbers: M12 FUEL Compact (2529-20). Small, light, handles conduit and small tubing. The M12 battery platform is shared with other M12 tools.

For general trades: M18 FUEL Compact (2829-20). Handles larger material than the M12 but is still manageable for overhead work.

For ironworkers and pipefitters: M18 FUEL Deep Cut (2929-20). Cuts up to 5-inch material. The Milwaukee 2729-20 is the older version and often available at a discount. Both versions use the same blades and batteries.

For shop use with no battery platform: Corded 6232-21 with variable speed. No batteries to charge, no battery to wear out. The variable speed is useful for cutting different materials.

FAQ

What is the difference between M12 and M18 band saws?

The M12 is smaller, lighter, and cuts material up to 1-5/8 inches. The M18 is larger and cuts up to 5 inches. The M12 uses 30-9/16 inch blades. The M18 deep cut uses 44-7/8 inch blades.

Are Milwaukee band saw blades interchangeable with other brands?

If the blade length matches, yes. Milwaukee 44-7/8 inch blades fit DEWALT, LENOX, and other deep cut saws. Milwaukee 35-3/8 inch blades fit DEWALT mid-size saws.

How long do Milwaukee band saws last?

With proper maintenance, 5 to 10 years of daily use. The brushless motor has no brushes to wear out. The main failure points are the switch, tension knob, and blade guides, all of which are replaceable.

What battery should I use with the M18 deep cut?

A 5.0 Ah battery is the minimum recommended. For extended use, 8.0 or 12.0 Ah batteries provide longer run time. The saw will run on a 2.0 Ah battery but will drain it in 15 to 20 cuts.

Can I get parts for older Milwaukee band saws?

Yes. Milwaukee supports parts for models going back 15 to 20 years. The online parts catalog has diagrams for the 6230 and 6232 corded models, which have been in production since the early 2000s.

What is the warranty on Milwaukee band saws?

Milwaukee offers a 5-year warranty on tools and 3 years on batteries. The warranty covers manufacturing defects but not normal wear parts like blades and guides.
