Introduction: Tools have enabled us to perform tasks that might be difficult or impossible to perform otherwise. The drill is a perfect example of this. Without a drilling device, we might be hard-pressed making a hole during a material like wood, including harder materials like concrete or steel, not that concrete and steel would probably exist without the utilization of other tools. We all know what a Drill is. A Drill is a motor tool that can be fitted with various rotating drill bits based on our usage. It can be used to drill holes, fixing screws, etc. Advanced Drills can also perform functions other than Drillings like Countersinking, Boring, Tapering, and Reaming. Most of the advanced Drilling machines are used just for Industrial purposes. But for our day-to-day household work, a small drilling machine would suffice.
Then it comes to What is the difference between CNC carbide drill bits and hand-use drills in the woodworking industry?
There are mainly 3 differences:
1: Different application scenarios
CNC carbide drill bits need to be equipped with quick couplings or threaded interfaces before they can be installed on the machine tool for normal use, while manual drill bits do not
2: Different materials
Industrial CNC drills materials are mostly alloy materials, while manual materials are basically carbon steel and high-speed steel
3: Different costs
In the market, the price of CNC carbide drills is about 3-5 times of that of hand use drills with carbon steel and HSS material.
4: Different production flow
In the production of CNC carbide drills, due to it has higher hardness and more heat resistance, it requires better equipments and technique when compared with hand-use drills bit
Now we will discuss this topic step by step.
Varieties of drills are pretended as per the industrial requirements. They are categorized supported on special parameters like manual drills and automatic drill machines. Manual drills are referred to as hand-milled drills used with hand force on the device/material to drill a hole. Physical drill variants are Bow drill, Gimlet, drill , and push drill, etc. These are mechanical with electricity or packed in the air known as electronic drill and pneumatic drill respectively. Drilling works are carried out at different locations with various types of drills including construction drills, wells drills, thermal drills, etc. All drills have special applications of drilling from little to larger size holes.
A pistol grip drill is normally used in our daily work. Right angle drill is employed in plumbing and electrical mechanism. A Hammer drill is liked to electrical drill with adding of hammer action on the same device. The rotary hammer drill is equipped with a rotation device used for drilling in solid constructions. Cordless drills with natural rechargeable battery power are used where the electrical supply is not reachable for drilling. Cordless drills consume high power. Thus need more spare batteries on charge throughout the drilling work to replace effectively on the discharge of installed batteries?
Main differences:
1: Different application scenarios
The material of industrial CNC carbide drill bits need to be equipped with quick couplings or threaded interfaces before they can be installed on the machine tool for normal use, while manual drill bits do not.
Both tools are employed by many professionals and amateurs. Although CNC drill tools are preferred in many industrial environments for his or her efficiency, others still use hand tools for more accurate and finer tasks. Both types have benefits in terms of the tasks that require to be done and therefore the industry. In general, for workers doing single and repetitive tasks, tools like table, chop, and band saws give the foremost efficiency.
But once you consider finer tasks like wood or metalworking, hand tools are often used for finer tasks.
2: Different materials
Industrial CNC drills materials are mostly tungsten carbide, while manual materials are basically carbon steel and high-speed steel，
Beginning with softer, simpler bits and advancing to stronger and more complex materials and designs, several steel types, steel alloys, carbides, and other coatings typically make-up a drill bit.
Picture 1: Tungsten carbide drill
Picture 2: HSS and steel drills
2.1 Low carbon steel:
Low carbon steel bits are soft and designed for working specifically with wood and soft plastics. They don't retain their cutting edges well and need frequent sharpening, as such, they're generally inexpensive and supply an adjunct that's practical and economical for several crafters.
2.2 High Carbon Steel:
Although these a still generally soft bits, high carbon steel bits are harder and more durable than their low carbon counterparts. They can be used in either wood or metal but lose their temper and sharp cutting edges if overheated.
2.3 High-Speed Steel:
High-speed steel is also called HSS. Because they've been additionally hardened and tempered, these bits are much more resistant to high temperatures and perform well in wood, metal, and most ceramic materials. From the name, we can know it performs well at very high speeds. They have, more or less, eliminated the demand for carbon steel bits among professional production workers.
3: Different costs
The raw materials difference will leads to the different cost.
The drill bit used on the CNC machine tool is made of cemented carbide, and the composition is tungsten carbide and cobalt. Among them, cobalt is a rare metal. The stock in the world is limited. With the development of electric vehicles, the demand for batteries is further expanded. Cobalt is needed as raw material, so the price of cobalt directly affects the price of cemented carbide.
Most of the hand use drills are made of carbon steel and high-speed steel, these two materials are currently relatively abundant supply in the world.
In the market, the price of CNC carbide drills is about 3-5 times of that of hand use drills with carbon steel and HSS material.
4: Different production flow and technical requirements
In the production of CNC carbide drills, due to it has higher hardness and more heat resistance, making their processing procedures and processes higher and more complicated than manual drills.
Therefore, the production cost of CNC drills is much higher than that of carbon steel and high-speed steel drills.
Conclusion:
Both hand and CNC tools are employed by many professionals and amateurs. Although CNC tools are preferred in many industrial environments for his or her efficiency, others still use hand tools for more accurate and finer tasks. Both types have benefits in terms of the tasks that require to be done and therefore the industry. In general, for workers doing single and repetitive tasks, tools like table, chop, and band saws give the foremost efficiency. Similarly, when workers are needed to figure with hard concrete or rocks, hand tools with manpower don't provide enough force, and ones like heavy-duty drivers and hammers are the only ones available for the task. But once you consider finer tasks like wood or metalworking, hand tools are often used for finer tasks.
