Long series drill bits

Types of Long Series Drill Bits

Long series drill bits are specialized drill bits used for drilling deeper holes than standard drill bits. The following are some common types of long series drill bits:

• Long Series Twist Drill Bits

  Long-series twist drill bits have a classic twist design and are available in various lengths and diameters. The design of the drill bits is primarily used for general-purpose drilling of wood, plastic, and metal. Long-series twist drill bits are often used as a standard drill bit.

• SDS Drills Bits

  SDS drill bits are used in conjunction with an SDS chuck and are specifically designed for hammer drilling. Hammer drilling refers to a drilling method that combines rotary motion with rapid concussive blows. This type of SDS drill bit is popular among professionals and DIYers for heavy-duty drilling into concrete, masonry, or stone. SDS drill bits typically have a solid carbide tip for durability and efficiency.

• Long Series Core Bits

  Long series core bits are used to drill precise holes in various materials, including concrete, masonry, and metal. Core bits have a hollow cylindrical shape with a cutting edge on the outside. The bits remove a core or cylinder of material while leaving an intact plug in the center. This creates an accurate hole with minimal damage to the surrounding material.

• Spade Bits

  Long series spade bits are flat bits widely used in woodworking projects. They are characterized by a flat, wide blade with a sharp tip to puncture and initiate the drilling. Long series spade bits are ideal for drilling large holes through wood and other soft materials such as plastic. The bits are often used in plumbing or electrical projects where large-diameter holes are required for pipes and wiring.

• Forstner Bits

  Forstner bits are used to drill clean and precise flat-bottomed holes in wood or composite materials. The bits can also create overlapping holes or cavities, as the bits have a unique design that allows them to drill at angles and even inside blind holes. Forstner bits typically have a smooth cutting edge and a center point for accurate positioning. When using in combination with longer drill bits, Forstner bits can help create complex hole geometries.

Specifications and maintenance of long series drill bits

The long series drill bits specifications mainly include the material, shank diameter, length, and head type.

• Material

  Long drill bits are made of different materials, such as HSS (High-Speed Steel), carbide-tipped steel, cobalt steel, and carbon steel. Every material has different features and performance. For example, HSS long drill bits are suitable for wood and soft metal. Cobalt steel offers better heat resistance and durability, making it ideal for tough metal materials. Ccarbon steel long drill bits are suitable for use in woodworking. Ccarbon steel lacks the durability and heat resistance of tougher materials, such as HSS or cobalt steel. Metal drill bits that are HSS with titanium coating can drill into a wide range of materials, such as hardwood, softwood, foam board, fiberglass, aluminum, brass, carbon steel, and, more importantly, steel.

• Shank diameter

  The shank diameter of the long bits varies. It can range from 1/8 inch to 1/4 inch or more. When people choose the drill bits, they need to consider the fit in the drill chuck.

• Length

  Long series drill bits come in various lengths, from a few inches to over a foot. Longer bits are suitable for drilling deep holes, while shorter bits provide better control and accuracy.

• Head type

  The head types of long drill bits include straight fluted, countersink, and tapered bits. Different head types suit different drilling applications, such as the straight fluted long drill bits, which are commonly used for drilling holes with straight sides and flat bottoms.

Long drill bits require proper care during use and storage. Attention to detail will help extend their life span. Following the above instructions will give people a better return on investment.

After using the drill bits, clean them with compressed air or a brush to remove any debris. Long bits with removable inserts can also be cleaned by removing the inserts. Ensure that the bit is completely dry before storage to avoid any corrosion and rust damage. If the bit is damaged or dull, repair it or replace it immediately.

Using any lubricant or coolant during the drilling process can help reduce heat buildup and friction. It's important to keep the drill bit and work material clean. This will help improve the drilling process and also enhance the drill bit's life span.

Always store drill bits in a case or holder to prevent any damage. Keeping them organized will make it easier to find them when needed and will also stop them from getting tangled or lost in storage.

Applications of Long Series Drill Bits

Long series drill bits are useful in various applications. They can drill deep holes in confined spaces and hard-to-reach areas and drill through multiple layers of materials. The following highlights some of the uses of long drill bits.

Plumbers use long drill bits to create holes in walls or behind fixtures for water pipes or drainage systems. They can also make holes in channels for electrical conduits. The bits create space for fasteners and anchors used to secure plumbing components and systems.

Long series drill bits are suitable for furniture makers and carpenters when installing hinges, handles, and other hardware in doors, cabinets, and furniture pieces. The bits can also create holes for dowels and mortise joints in complex furniture constructions.

Long drill bits used by electricians can create channels in walls for electrical conduits or wiring. They are also suitable for making holes in light fixtures and electrical boxes. The bits are useful for penetrating through walls or floors to install electrical outlets and switches.

In the automotive industry, long drill bits help when penetrating hard-to-reach areas of an engine or chassis to install sensors or lighting components. The bits can create access holes for repairs or modifications in confined spaces, such as inside the dashboard or behind interior panels.

Construction professionals use long drill bits to install anchors, bolts, or plumbing fittings in thick structural components such as concrete, steel, or wood. They are also useful when creating penetrations for plumbing, electrical, or HVAC systems through walls, floors, or ceilings.

Long drill bits are used for precise deep hole drilling in wood, plastic, and soft metal in DIY projects. Specific drill bits, such as the forstner bit, are used to create clean, flat-bottomed holes. The bits drill holes needed for cabinet installs, furniture assembly, or hardware placement.

How to choose long series drill bits

When purchasing a long drill bit series for resell or industrial use, it is important to consider factors that will meet end users' needs. Firstly, the material of the bit should be considered. HSS and cobalt HSS offer a wide range of applications, but customers will go for a drill bit with scheduled high-performance in demanding use. So, tungsten carbide, titanium, or black oxide drill bits should be on the list when purchasing for industrial use or professionals. Also, the coating of the drill bit affects its performance as well. Choosing drill bits with varying coatings can help meet users' diverse needs.

The length of the drill bit is another factor to consider when purchasing long drill bits. Ideally, buyers should consider purchasing a variety of lengths and sizes to meet a standard market need. Also, the point angle can affect how the drill bit cuts through material or customers will prefer drill bits with varying point angles to cater to distinct wood or metal product segments.

Another thing to consider is the packaging of the long drill bits. Many brands package long drill bits in plastic or metal cases to prevent breakage. When purchasing for retail stores, it is advisable to go for different packaging options. In most cases, retail buyers go for well-packaged drill bits to ensure their customers get quality products.

Finally, whether to get stocked or not should be priority when purchasing long series drill bits. Getting stocked up can help to get a better price and reduce the cost of reordering. Compare different suppliers to see who offers a better deal when stocked up.
