What You'll Learn

Use a saw with a metal-cutting blade
If you want to cut a screw or nail that is embedded in wood, metal, or plastic, you will need to use a saw with a metal-cutting blade. Metal-cutting blades can be used with almost any type of saw, including circular saws, jigsaws, and reciprocating saws.
Before you begin, ensure that your metal-cutting blade has at least 10 teeth. Additionally, lubricate the blade to reduce wear and resistance. When cutting, use the backside of the blade to prevent damage to the wood-cutting side.
Reciprocating saws, also known as Sawzalls, are particularly useful for cutting hard-to-reach screws and nails. They can be inserted into small spaces and are effective at cutting fasteners that hold two pieces of wood together. When using a reciprocating saw, ensure that the saw is fastened to a solid surface and that you are holding the saw guard tightly against the wood to limit binding and pinching.
Hacksaws are another option for cutting screws and nails. They are general-purpose metal-cutting saws that are useful for reaching into narrow gaps. However, they may require more physical effort, especially when cutting larger screws.

Keyhole saws are useful when you don't have clearance for other tools
When it comes to cutting nails or screws, there are several methods and tools you can use, including snipping, sawing, and grinding. Snipping with wire cutters or bolt cutters is a good option when you want to cut the head of a screw or nail off. However, if you want to cut through the shank of a screw or nail, sawing is often a faster method, especially for thicker fasteners.
While various saws can be used for this purpose, keyhole saws are particularly useful when you don't have clearance for other tools. Also known as pad saws, alligator saws, jab saws, or drywall saws, keyhole saws are long and narrow, making them ideal for cutting small, awkward features in various building materials. They can access tight spaces that other saws cannot reach. The retractable-blade variety of keyhole saws can be adjusted to an optimum length, preventing unwanted flex when the full length of the blade is obstructed. This feature further enhances the ability of the keyhole saw to access confined areas.
When using a keyhole saw or any other type of saw to cut nails or screws, it is essential to use a metal-cutting blade. These blades typically have a tooth count of more than 10 teeth per inch, enabling them to cut through metal fasteners effectively. You can find metal-cutting blades for various saw types, including circular saws and reciprocating saws.
Reciprocating saws, also known as Sawzalls, are commonly used in construction and demolition to cut nails and screws. They can be inserted into small spaces around the fastener and anchored to a solid surface to reduce vibration during cutting. This feature makes them versatile and effective for cutting nails and screws in confined areas.
In summary, keyhole saws are indeed useful when you don't have clearance for other tools. Their narrow blades and retractable-blade varieties make them ideal for tight spaces, and when equipped with metal-cutting blades, they can effectively cut through nails and screws.

Diamond grinding wheels can cut through nails, bolts and screws
Diamond grinding wheels are an effective way to cut through nails, bolts, and screws. They can be affixed to both small and large rotary cutters, allowing for flexibility depending on the size of the job. Diamond grinding wheels are also compatible with angle grinders, which are powerful metal-cutting tools that can fit into small spaces. Angle grinders are a popular choice for metalworkers cutting heavy bolts.
Diamond grinding wheels are known for their strength and durability. They can cut through a variety of materials, including metal, stainless steel, bronze, brass, nuts, bolts, screws, ferrous and non-ferrous metals, and PVC pipes. They can also be used on materials like gypsum, ceramic, glass, and stone, making them versatile tools for a range of projects.
When using diamond grinding wheels, it is important to consider the material being cut and the speed of the tool. For example, when cutting PVC pipes and small bolts, a lower speed may be sufficient, while larger bolts and harder metals may require a higher speed for effective cutting. Additionally, it is important to prioritize safety and wear appropriate protective gear when operating power tools.
Diamond grinding wheels are available in different sizes, such as the commonly found 2-inch variety. They are known for their precision and ability to ensure high-speed cutting, long-lasting stability, and fracture resistance. The diamond grain coating contributes to their durability and cutting capability. Overall, diamond grinding wheels offer a combination of performance, precision, and versatility for cutting nails, bolts, and screws.

Angle grinders are powerful metal-cutting tools
Angle grinders are powerful tools for cutting metal and are commonly used by professionals for their versatility and precision. Also known as disc grinders, right-angle grinders, or side grinders, they can cut through both hard and soft metals with ease. With the right cutting disc, angle grinders can be adjusted for precise cutting, making them ideal for preparatory work. They are excellent for cutting metal pipes, sheet metal, and bolts, and can even cut through denser steel like rebar.
When using an angle grinder, safety precautions are crucial. It is important to always use blades rated for angle grinders and to ensure that the safety guard is in place, facing your body. The grinder's versatility extends beyond metal cutting; with different discs, it can sharpen tools, polish metal, and grind out mortar. Angle grinders range in size, with 4.5-inch models suitable for common tasks and larger 9-inch grinders designed for industrial applications.
For cutting nails or screws, a reciprocating saw is often recommended. These saws, also known as Sawzalls, are commonly used on construction and demolition sites as they can cut through almost any size and diameter of fastener. When equipped with metal-cutting blades, they can easily slice through nails and screws. Additionally, jigsaws operate similarly but require a solid surface for the blade to rest on, making them less versatile than reciprocating saws.
Snipping is another method to cut nails or screws, especially when wanting to remove the head of a nail or screw protruding through the material. This can be done with bolt cutters or wire cutters, choosing the appropriate tool based on the hardness of the metal and the fastener's diameter. Bolt cutters are heavy-duty wire cutters with long handles, making them ideal for fasteners with larger diameters. However, their size also means they require more space to operate.
When using power tools like angle grinders or reciprocating saws, it is important to prioritize safety and always follow the recommended guidelines for the specific tool.

Wire strippers can be used to cut bolts
While it is not a common use case, wire strippers can be used to cut bolts. This is done by squeezing the handles together to apply force to the bolt. However, this method can be difficult to control and may not be suitable for all types of bolts. It is important to use the right tool for the job, depending on the hardness of the metal and the diameter of the bolt.
When cutting bolts, it is important to use the correct technique to ensure a clean and precise cut. In general, there are three main methods for cutting bolts: snipping, sawing, and grinding. Each method has its own advantages and disadvantages, and the best method will depend on the specific application.
Snipping is a good option when you want to cut the head off a bolt or when you need to cut a bolt with a large diameter. Bolt cutters, which are a type of wire cutter with long handles, are commonly used for snipping bolts. This method can provide a precise cut that preserves the look of the finished product, but it can also be time-consuming.
Sawing is another option for cutting bolts. Reciprocating saws, also known as Sawzalls, are commonly used for this purpose and can cut through almost any size and diameter of the fastener. This method can be faster than snipping, especially for thicker bolts. However, it is important to use a metal-cutting blade when sawing through bolts to ensure effectiveness.
Grinding is the third method for cutting bolts and involves using a tool such as a diamond grinding wheel or an angle grinder to cut through the metal. This method is often used by metalworkers for cutting through heavy bolts and can be very effective.
While wire strippers can be used to cut bolts in a pinch, it is important to consider the limitations of this method and choose the appropriate tool for the specific application.
