Handsaws or panel saws are used in cutting wood into various shapes in carpentry and woodworking work. It consists of a blade having teeth that cut the hardwood into pieces. The large teeth in handsaws are generally for softwoods whereas the small teeth are for hardwoods. Generally, to rip the softwood the handsaws that have 2 to 8 teeth per inches and cutting hardwoods the blades of medium size having 10 to 20 teeth per inches are used. However, to cut very hard wood or the precise and actual cuts, the handsaws having the blades with 20 to 30 teeth per inches are available.
- Teeth available in various shape and size
The teeth of blades in hand saws are of various shapes and direction that indicates what type of wood is to be ripped or how to be ripped. In handsaws, two types of layouts are most common i.e. rip cut and crosscut. The crosscut saws have narrow pointed blades and sharp edges. These pointed sharp edges works as small knives that cut kerfs from both sides. The crosscut handsaws work on both push and pull strokes but it works better when stroked in one direction. Rip cut hand saws consist of blades that have quite thick teeth and only their below edges are sharp. These teeth work as tiny incisors and only chip the wood and work only in one direction i.e. either at pull stroke or push stroke that depends on the blade of the hand saw.
Contemporary utility knives
These are the perfect choice for those who want a versatile knife that can work well both in indoor and the outdoor. You can use them in cutting trades, crafts in your home. You can cut wire edges, constructional objects and many more when you take them with you outside of your home.
An angle grinder or disc grinders are the powerful handheld tools that are used for metalworking, polishing and grinding in construction works. These angle grinders are the electronic tools that work with the help of a petrol engine, compressed air, batteries or an electric motor. This tool consists of a guard that can be adjusted as per the requirement and one side handles to comfort the user to use it by two hands. However, angle grinders are basically for rough discs due to its ability to interchange power source they are used with various attachments and cutters. Angle grinders are also used in removing the unwanted or excessive material from a portion.
- The Grinder Usage
These grinders are used for various tasks and thus their discs are of different types such as diamond blade, polishing pads, abrasive grinding discs, sanding discs and for grinding stones, etc. The backside of the angle grinders is of hard plastic, hard, or medium rubber as per the desirable flexibility. The large bearings of angle grinders generate the force from sides while cutting not as the axial force of a power drill. These grinders are found in automobile repair shops, workshops, and garages of vehicle service. While choosing an angle grinder the size of disc and power of motor shall be considered as per the requirement. Size of discs are measured in millimeters and inches some of them are 4.5, 5. 6 inches, etc. These angle grinders can grind metals, stones and can even cut tiles and pavers, etc along with polishing and sharpening of the abrasive surfaces.
12. Cordless Drill
A cordless drill is an electric tool that contains batteries that are rechargeable. Cordless drills are used for making round holes for driving fasteners into them. Drills are changed according to their sizes, power, and speed. Cordless drills are offered with the features that are quite similar to the AC mains power drill. These drills are of the common type and are available in the configuration of a hammer drill and the majority of them consist of a clutch that aids while driving screws into fasteners or others without destructing them. The right angle in cordless drills allows its user to drive the screw in a rigid space. To use these cordless drills continuously one has to carry another battery packs during drilling. Nowadays, batteries that are quickly rechargeable are also available that charges within 10 to 15 minutes.
- The NiCd batteries
The interchangeable battery packs available in cordless drills are usually of 18 V but the battery packs of high voltages are also available that are up to 24 V, 28 V & 36 V. The higher voltage of these batteries allows these cordless drills to produce torque similar to the corded drills. The most common batteries used in cordless drills are NiCd and lithium-ion batteries. The advantage of NiCd batteries is that they are less expensive but its disadvantages are that it has limited durability and is self-dischargeable. Lithium-ion batteries are the most common due to its less time of charging, low weight and longer life. The Lithium-ion batteries can be kept charged for about two years when not used whereas the NiCd battery lasts for one to four months only.
Hacksaw is a type of hand-held tool having a fine-toothed blade used for cutting wood. The blade of the hack saw is replaceable and can be replaced and removed whenever its teeth get blunt. It consists of two tiny holes at the opposite ends of the blade through which it is fixed in the frame. Blades of hacksaws are basically available in 250mm and 300 mm i.e. approx 9.8 and 11.8 inches. The blade of size 300mm is used mostly, however, the hacksaws that have adjustable frames accept the blades of 250mm also along with blades of 300mm.
- The magic of blade
The blades of hacksaws are designed in such a way that it works only on the push stroke. While using hacksaw one should place the blade in frame pointing the teeth slightly at a distance from the handle. Hacksaw consists of the blades that have small teeth and a straight gullet and hence it removes and cuts only a small portion at each stroke in carpentry work. Hence, working with hacksaws provides slow work through which the work provided shows a neat and clean finish.
Tooth of the blades in hacksaws seems like the line of a wave that helps in keeping the blades more durable when used on hard metals. It has 14 to 32 teeth per inch and generally, 18 teeth are appropriate for cutting soft metal or hard plastic. For cutting, the metals like steel hacksaws having blades with 20 to 32 TPI are used. The handles of hacksaws are basically large and closed that helps in avoiding to slip out during quick sawing process.
14. Drill Bit
Drill bits are the cutting tools used to create holes in materials. These are available in varying shapes and sizes. The wide variety helps in creating different types of holes in different materials. The cutting work on materials is carried out by attaching the drill bit to drill which powers the rotation. The chunk of the drill holds the upper end of the bit called shank.
Drill bits made of hard materials are prone to breaking particularly when the drill is not operated in a constant angle. Drill bits made of different materials are available in the market. Bits made of certain materials are suitable for making holes in some materials. Some drill bits are convenient for woodwork while others are more suitable for metal works. Bits with flatter points (135° angle ) are suitable for drilling harder materials while steeper points (118°) is best for softer material usage. For home works and workshops bit set with sizes ranging from 1/16 into 1/4 in are best.
- Drill Maintenance
All the drill bits come with a coating to protect it from corrosion and maintain its heat resistance. Twist drill bits are universal as these are produced in the largest quantity in the market. Like the name, these bits consist of a cylindrical shaft with helical flutes and a pointed tip. The advantage of this structure of the bit is its ability to lift swarf out of the hole. Any drill bits selected should be compatible with the material to be drilled and the tool to be used.
Credited as the silent heroes of any workshop, clamps are fastening devices that are used to hold the objects tightly together. This tool prevents the movement or even separation of the object when subjected to inward pressures. Though there are wide arrays of clamps available in the market today, all share the same fundamental parts and operating principle. The object is held between two jaws of the clamp. One jaw is usually fixed while the other is moveable.
- Adjusting jaws for pressure
The moveable jaw can be adjusted and tightened to create the required clamping pressure for the work. The closing mechanism of many clamps has screw thread with pivoting foot while other clamps feature ratchet or cam activated tightening parts.
While buying a clamp, the jaws are the most important parts to be considered. Jaws are the only parts that meet the work object. If the jaws are small in size then the pressure applied on the working object is more and can cause indentations. If the jaws have large faces, the pressure applied to the object is spread throughout the wide area of the jaw. This will not damage the work object. The weight of the clamp is another factor to be considered while buying clamps. Lighter clamps are sufficient for delicate or smaller work assemblies.
Clamps are popularly used in carpentry, masonry and most of the DIY works. Clamps can be used for temporarily holding the position of the objects or can be intended to be used permanently.
