Beginners Guide to Hacksaws: Types and Applications

The definition, applications, handling techniques, and variety of hacksaws are covered in this guide.

A HACKSAW: WHAT IS IT?

One kind of hand tool made especially for cutting through materials like plastic, steel, and other metals is the hacksaw. They are an improved version of the classic hand saw, usually employed for woodworking, and have grown to be indispensable instruments for both experts and enthusiasts.

Hacksaws are perfect for a variety of tasks and uses because they provide strong, accurate cutting force. Their unique adjustable frame, like the letter "D," is what gives them their distinctive physical appearance and keeps the blades under tension.

COMPONENTS OF A HACKSAW

HACKSAW FRAMES

Often referred to as blade holders, hacksaw frames typically have an ergonomic handle (a pistol grip, for instance) and come with pins to attach new blades. Usually constructed of steel or aluminum, the frames can be modified to fit blades of varying sizes.

HACKSAW BLADES

There are numerous sizes of hacksaw blades available to cut a range of materials. Although hacksaw blades can be as short as six inches (150 mm), twelve inches (300 mm) is the most typical length. Pins that are placed into holes at either end of the blade are used to mount blades onto hacksaw frames. The length of the blade is found by measuring the distance between these holes.

COMMON USES FOR HACKSAWS

Hacksaws are a common tool used by professionals such as mechanics, electricians, and plumbers for daily chores. Hacksaws are frequently used for the following purposes:

• Sawing pipes.
• Shaping metal sheeting.
• Cutting plastic.

TYPES OF HACKSAW

To serve a multitude of industries and applications, hacksaws are made in different sizes and shapes. The main categories of hacksaws are:

FULL - SIZED HACKSAW

Full-sized hacksaws, also referred to as senior hacksaws, are huge, multipurpose, easy-to-use instruments that quickly cut through hard materials. They work with blades that have 12, 18, 24, and 32 teeth per inch.

JUNIOR HACKSAW

Smaller versions known as junior hacksaws are employed when space is at a premium or when fine cutting is necessary. They are not appropriate for cutting harder materials because of their soft, half-sized blades. Junior hacksaws are small hand tools that are very portable.

MINI HACKSAW

Small hacksaws are lightweight, portable types made for cutting in tight areas and reaching difficult-to-reach places like home plumbing. Typically, they have extremely small D frames and long, ergonomic handles.

POWER HACKSAW

Electric motors are typically integrated into power hacksaws, also referred to as electric hacksaws, to power their blades; however, they can also be connected to external motors or engines. Powered hacksaws often raise their blades automatically on the return stroke. Power hacksaws are usually stationary tools, however, there are also portable versions available. Another typical addition to assist in keeping the blades from overheating while in use is a cooling pump.

THE RIGHT WAY TO USE A HACKSAW

As with any other tool, using a hacksaw safely requires maintaining focus and paying close attention to details. Here are some excellent guidelines for safe hacksaw use:

• Verify that the blade you have selected is appropriate for the job.
• Make that the blade is installed with its blade facing forward.
• Verify that the blade is fastened securely to the frame securely.
• Secure the object you are cutting firmly, for example, with a vice.
• Cut hard, being careful to keep your body out of the way as you see.

HOW TO REPLACE THE BLADE ON A HACKSAW?

Whether you are using a junior or senior model, changing a hacksaw blade is a simple procedure. Here's a helpful, step-by-step instruction that explains the procedure:

• To loosen the current blade on your hacksaw, use the fasten-release mechanism or turn the wing nut, depending on the model.
• Slide out the existing blade with caution.
• Place the new blade onto the handle's retention pins.
• You can either replace the fasten-release mechanism or tighten the wing nut.
• To make sure the new blade is secure and safe, test cut a piece of scrap metal.

HOW A HACKSAW IS MAINTAINED?

Maintaining and repairing your hacksaw on a regular basis can guarantee a high-quality cut while lowering the danger of injury from handling the instrument. The following principles should be kept in mind when doing hacksaw maintenance:

• Hacksaw blades should routinely be inspected for problems, such as warping or blunting.
• Replace the blades if there are indications of wear and tear.
• To keep the blade from overheating during cutting, lubricate or oil it.
• Cut slower when cutting harder materials to reduce the chance of breakage.
• To extend the life of your hacksaw blades, give them regular cleanings.
