Reciprocating Saws: An Overview

A reciprocating saw is your go-to tool for demolition, remodeling, and some construction tasks. Its strong cutting action and ability to fit into tight spaces make it a versatile choice for many jobs.

Types of Reciprocating Saws

• Corded: These saws offer consistent power and are ideal for heavy-duty tasks. You plug them into an outlet.
• Cordless: These saws give you freedom of movement. They run on batteries, making them great for jobs where outlets are far away.

Key Features to Look For

• Variable Speed Control: Lets you adjust the cutting speed for different materials.
• Tool-less Blade Change: Makes swapping blades quick and easy.
• Adjustable Shoe: Helps keep the saw stable against the material you’re cutting.
• Orbital Action: Moves the blade in a small oval pattern, speeding up cutting in wood.
• Vibration Reduction: Reduces user fatigue during longer jobs.

Using a Reciprocating Saw Safely

Can I use a reciprocating saw safely? Yes, using a reciprocating saw safely is crucial. Always wear the right safety gear and follow best practices to avoid accidents.

Essential Safety Gear

• Safety Glasses: Protect your eyes from flying debris.
• Hearing Protection: Reciprocating saws can be loud; use earplugs or earmuffs.
• Gloves: Protect your hands and improve your grip.
• Dust Mask: Wear a mask if cutting materials that create dust.
• Steel-Toed Boots: Protect your feet from dropped materials or tools.

Safety Procedures

• Inspect the Saw: Before each use, check the cord (if corded), blade, and all parts for damage.
• Secure the Material: Clamp or brace the material you’re cutting to prevent movement.
• Keep a Firm Grip: Hold the saw firmly with both hands.
• Maintain a Safe Distance: Keep your free hand away from the blade.
• Unplug or Remove Battery: Always unplug the saw or remove the battery before changing blades or making adjustments.
• Avoid Overreaching: Don’t reach too far or cut in awkward positions.
• Be Aware of Your Surroundings: Make sure there are no electrical wires or pipes in the cutting path.

Reciprocating Saw Techniques

To get the best results with a reciprocating saw, you need to master a few basic reciprocating saw techniques.

Basic Cutting

1. Mark the Cut: Clearly mark the cutting line on your material.
2. Position the Saw: Place the shoe of the saw firmly against the material.
3. Start Slowly: Begin cutting at a slow speed to prevent the blade from jumping.
4. Apply Steady Pressure: Let the saw do the work. Avoid forcing it.
5. Follow the Line: Keep the blade aligned with your marked cutting line.

Plunge Cutting

How can I perform plunge cutting with a reciprocating saw? Plunge cutting involves starting a cut in the middle of a surface, without starting from an edge. Here’s how:

1. Tilt the Saw: Angle the saw so the tip of the blade is touching the material.
2. Start Slowly: Begin cutting at a slow speed, gradually lowering the blade into the material.
3. Maintain Control: Keep the saw stable and avoid applying too much pressure.
4. Continue Cutting: Once the blade has pierced the surface, continue cutting along your marked line.

Cutting Metal

Is it possible to cut metal with a sawzall? Yes, cutting metal with a sawzall is possible, but you need the right blade and technique:

1. Use a Metal-Cutting Blade: Choose a blade designed for cutting metal. These blades have finer teeth.
2. Slow Speed: Use a slower speed to prevent overheating the blade.
3. Lubricate the Blade: Apply cutting oil or lubricant to reduce friction and heat.
4. Steady Pressure: Apply consistent pressure and let the blade do the work.
5. Secure the Metal: Clamp the metal securely to prevent it from vibrating.

Cutting Wood

Can I use a sawzall for wood cutting? Yes, a sawzall can be effective for wood cutting, especially for demolition or rough cuts.

1. Use a Wood-Cutting Blade: Select a blade designed for wood. These blades have larger teeth.
2. Adjust the Speed: Use a higher speed for softer woods and a slower speed for harder woods.
3. Orbital Action: If your saw has orbital action, use it to speed up cutting in wood.
4. Follow the Grain: Cut along the grain of the wood for smoother cuts.

Reciprocating Saw Blade Selection

Choosing the right blade is vital for efficient and safe cutting. This section provides a detailed reciprocating saw blade selection guide.

Blade Materials

• High-Speed Steel (HSS): Good for cutting wood, plastic, and non-ferrous metals.
• Bi-Metal: Combines HSS teeth with a flexible steel body for increased durability and resistance to breakage. Excellent for cutting a variety of materials, including wood and metal.
• Carbide-Tipped: Extremely durable and ideal for cutting tough materials like hardened steel, cast iron, and abrasive materials.

Teeth Per Inch (TPI)

• Low TPI (6-10 TPI): Best for fast, rough cuts in wood.
• Medium TPI (10-18 TPI): Good for general-purpose cutting in wood and metal.
• High TPI (18-24 TPI): Ideal for smooth cuts in metal and thin materials.

Blade Length

• Short Blades (4-6 inches): Good for tight spaces and detail work.
• Standard Blades (6-9 inches): Suitable for most general-purpose cutting tasks.
• Long Blades (9-12 inches): Best for cutting thick materials and demolition work.
• Extra-Long Blades (12+ inches): Designed for specialized applications, such as tree pruning or cutting through very thick walls.

Blade Types and Uses

Blade Type	Material	TPI	Length	Application
Wood Cutting	Wood	6-10	6-9 inches	Fast, rough cuts in wood, demolition
Metal Cutting	Metal	18-24	6-9 inches	Smooth cuts in metal pipes, sheets, and rods
Bi-Metal	Wood & Metal	10-18	6-9 inches	Versatile, general-purpose cutting
Demolition	Wood, Metal, Nails	6-10	9-12 inches	Cutting through embedded nails and mixed materials in demolition projects
Carbide-Tipped	Hardened Steel	14-18	6-9 inches	Cutting very hard metals and abrasive materials
Pruning	Tree Branches	3-6	9-12+ inches	Pruning trees and shrubs

Demolition Saw Tips

Reciprocating saws are excellent for demolition. Here are some demolition saw tips to help you get the job done efficiently.

• Use a Demolition Blade: These blades are designed to cut through nails, screws, and other embedded objects.
• Cut Strategically: Plan your cuts to remove large sections of material at once.
• Watch for Hidden Obstacles: Be aware of electrical wires, pipes, and other hazards behind walls.
• Use a Longer Blade: A longer blade can reach into tight spaces and cut through thicker materials.
• Control Dust: Use a dust mask and consider wetting down the area to reduce dust.

Best Practices for Reciprocating Saws

To keep your reciprocating saw working well and lasting longer, follow these best practices for reciprocating saws.

• Clean the Saw: After each use, clean the saw with a brush or compressed air to remove dust and debris.
