What are PCD Drilling Tools?
Polycrystalline Diamond (PCD) cutting tools are applied in the process of cutting aluminium, brass and copper, graphite and other materials like wood, plastic and carbon-fibre-reinforced polymer (CFRP). So, they are basically used to obtain high abrasive resistance and high hardness. These motives result in a longer life for the cutter in comparison to conventional cutters. These tools also customise designs to fit your exact measurement specifications.
PCD Drilling Tools
A drilling tool is an instrument basically used to make circular holes or go about as driving fasteners. It is fitted with a bit upon the size and finishing required. PCD Drilling Tools, on the other hand, is utilized for drilling aluminium and magnesium, wood, plastics, CFRP, GRP materials and that’s only the tip of the iceberg.
They accompany fantastic wear-safe properties while machining profoundly abrasive materials and conferring to the tool an incredibly long tool life contrasted with the standard Carbide drilling tools.
Types of PCD Drill Bits and their uses
Twist Drill Bit
A twist bit is the most common type of drill bit in the PCD drilling tools category for home use. It works for general-purpose drilling in wood, plastic and light metal.
Auger Drill Bit
An auger bit, another type of wood-boring bit, has a screw tip that starts the hole and pulls the bit through the workpiece to quickly create a clean hole. These bits can be as long as 18 inches. As with the brad-point bit, large flutes help remove chips and dust. An auger bit with a hollow centre provides even more chip removal, allowing for deeper boring; one with a solid centre is stronger and more rigid.
PCD Step Drill Bit
A step drill is primarily intended to drill thin metal, up to 1/4 inches. But, that only works with wood. The design specially allows using a single bit to drill holes of different diameters. The diameter of each step is usually etched into the metal drill bit. You can also deburr holes to clear waste materials.
PCD Hole Saw
A hole saw drills large holes for installing door hardware or creating a pass-through for wiring. It also creates a plug of waste material; a cut-out in the side of the saw cylinder allows you to push it out. Typically, a hole saw attaches to an arbour or mandrel, which includes a shank. The arbour also holds a pilot bit for centring and steadying the cutting blade. Some smaller hole saws have a built-in shank and don’t use a pilot bit. A bi-metal hole saw cuts through wood and metal. A hole saw with a diamond edge also works on tile and masonry but cuts faster than carbide models.
Masonry Drill Bit
This bit drills into tough materials such as concrete, brick and other masonry. If you did not know, some work with standard corded or cordless rotary drill. However, those designed for the use with rotary hammer or hammer drill helps the concrete drill bit bore more effectively.
Other materials usage
Brad-point Drill Bit
A brad-point bit is designed for boring into wood. The brad at the centre of the bit tip helps position the bit precisely for accurate drilling and produces a clean exit point in the workpiece. The flutes — grooves that wrap around the bit and channel away chips and dust — are extra-wide to remove more material.
Self-feed Drill Bit
A self-feed bit drills through the wood. Like the auger bit, a screw at the tip helps position the bit and draws it through the workpiece. However, this bit is more compact. It doesn’t have the standard flutes of a twist bit, so you need to pull the bit back periodically to clear away chips and dust.
Installer Drill Bit
An installer bit is a specialized twist bit designed for installing wiring like what’s used for entertainment or security systems. The bit can be up to 18 inches long and drills through wood, plaster and some masonry. Once you drill through the wall, floor or other surfaces, you insert a wire into the small hole in the bit and use the bit to draw it back through the hole you bored. You can then attach this wire to additional wire or cable and pull it through the hole.
PCD Spade drill bit
A spade bit, also known as a paddle bit, bores large-diameter holes — up to 1-1/2 inches in diameter — in wood. It has a flattened blade with a sharp point that helps position and steady the bit. Some spade bits have points at the two edges that help create a neater hole and exit point.
PCD Forstner Drill Bit
A Forstner bit bores smooth, clean holes in wood. You can use it to create flat-bottomed holes for receiving dowels. If you need to bore through the workpiece, it creates a neat exit hole. The design also allows you to overlap holes. The point helps you to position the bit precisely on the workpiece. So, pull the bit out regularly to clear away chips and dust as you work. A handheld drill may not always give you the force or control you need to use a Forstner bit, so a drill press is a better option for some applications.
Countersink Drill Bit
A countersink bit, also known as a screw pilot bit, is a forte bit for wood drilling. Via a single action, the bit can drill pilot, countersink and counter drill holes, permitting to countersink a fastener and install a plug over the fastener head.
A plug cutter drills holes in the wood creating wood plugs to conceal recessed fasteners.
Every PCD Drill Bits has its functions
Study your materials well enough to know which PCD drill bits suit your high precision manufacturing process.
A little change in the design of PCD drill bits creates a different effect to its drilling finish. Sometimes, some drill bits can be used on various materials too which brings greater benefit to you.
