Traditional hacksaws are no longer familiar to everyone, as wired and battery-powered jigsaws have emerged as a tool suitable for most DIYers. And an electric or reverse indeed saw fitted with the right blade can serve most of the functions performed by a saw blade. However, as same as every professional plumber knows, the best hacksaw still has its place, and you should add it to your tool collection.
In addition to being an inexpensive tool, the best hacksaw has a large cutting surface that is ideal when you cut large tubes and have perfect teeth to cut metal smoothly. As a classic plumber’s tool, the best hacksaw is primarily a tool for cutting metal, such as steel pipes or sheet metal, but it is also beneficial for cutting plastic pipes when you have no work. Specialized tools are designed for that purpose.
The key to effective hacksaw is understanding the different blades available for the tool and choosing the right one for the job. In this article, I will give you how to use the best hacksaw.
The construction of a hacksaw
A saw blade is a straightforward tool, consisting of an elongated C-shaped frame with a handle on one end, and a flexible, narrow blade mounted on the pins and stretched across the open face of the frame. There are also small saw frames that allow one end of the blade to extend over the handle. They are well suited for use in confined spaces where full-size saw frames are not suitable.
Types of blades
Hacksaw blades are available with the number of teeth ranging from 14 to 32 teeth per inch. Thin stocks call for better teeth; Thicker metal requires fewer teeth per inch. The way teeth are positioned on a tongue is called the set. There are three typical sets of sawtooth:
- Frequently: These work well on softer non-ferrous metals. The sawbucks are lined up, touching each other and alternating left and right.
- Raker: Perfect for cutting into thick metal. The teeth are placed in a trio.
- Wavy: A suitable choice for thin, hard metals. The teeth are placed in a wave pattern from left to right for smooth, smooth cutting.
Types of frames
The saw frame can be fixed or adjusted. A fixed frame accepts a blade length while tuning usually handles 10 and 12-inch blades; Some may accept blades from 8 to 16 inches. There is a slight difference in price, but the flexibility of the adjustable frame is well worth the extra cost.
An iron saw has a hole at each end that matches the pegs on the frame, and these pins can be placed in four positions: up, down, left and right. Additionally, the blade can be mounted on pivots with the serrated face in either direction. Then, you will get a total of eight blade positions to choose from.
The key to success when using a hacksaw is to attach the blade so that it fits within the frame and cut using slow, steady strokes. Americans are accustomed to cutting saws on the push-up stroke, but reversing the blade to cut strokes, as is the case with good Japanese wood saws, sometimes gives you better results when using a hacksaw. Whatever the orientation of the blade, it is necessary that you cut slowly, no more than one stroke per second; Metal on metal generates tremendous heat and can quickly damage a blade. A drop of lubricant on the blade helps reduce friction and keeps temperatures down. Overheating can quickly become dull.
Safety tips for hacksaw
For best results, when using a hacksaw, you should follow these practices:
- Select the right cutting edge for the material to be cut.
- Fix the blade with the teeth facing forward if you want to cut on the push; Step back if you want to cut on the drag stroke.
- Keep the blade stiff and the frame aligned correctly. The blade must be very tight in the frame for efficient cutting.
- Cut using sharp, slow, steady strokes.
- Use the total length of the blade when each cutting stroke.
- Keep the saw clean, and use light machine oil on the blade to keep it from overheating and breaking.
- Cut hard materials slower than soft materials.
- Thin clamps, flat pieces require cutting edges.
- If you are cutting pipes, always make sure it is safe before cutting.
Above, I have shown you how to use the best hacksaw and some safety tips when doing with it. I hope that it will help you do the work effectively.
