Types of Drill Bits and Their Functions: Choose the Right One for Your Needs

Drill Bit

Drill bits, or mata bor, are tools used to create holes in a material.
specific objects like wood, metal, glass, walls (concrete), and
plastic. There are various types and sizes to create holes.
using different types of machines, their functions also vary.
That's why, before buying them, due to each material or substance.
we will bore using them surely has its own strength.
different, of course, this cannot be done.
using the same type. Therefore, every manufacturer designs and.
produces various types of drill bits so that they can be used according to.
the established criteria, but it should be noted that each type of drill bit.
drill bit certainly has its own advantages and disadvantages.

 

Here are the types of drill bits that we can buy according to our needs:

1. Twist bits are commonly used drill bits and have.
   universal functionality. Types of Twist Bits or Jobber bits are also
   known as Spiralbohrer by technicians from the past who.
   generally use the German term. These drill bits can be used on.
   handheld or benchtop machines, both horizontally and vertically, and.
   can be used to drill wood, plastic, and metal. The size.
   available in the market today range from 4-12mm, but there are also.
   very small sizes for creating screw threads. You.

2. Masonry bits are drill bits that can be used to drill through hard surfaces made of natural stone or concrete and are often used for drilling into walls, concrete, and various stones. They typically have a blunt blade tip made of very hard materials because they are designed to both rotate and impact the surface. Masonry bits come in sizes ranging from 4-15mm in the market. Masonry bits can also be differentiated based on the tool's function, typically varying at the base. The standard shape is used for regular units like impact drills or hammer drills, while specialized shapes like SDS drill bits are used for SDS drill or Demolition Drill units.

3. Spur drill bits are drill bits typically used for wood and.
   for hinge installation purposes. These drill bits have a pointed tip on the.
   end and blades around its circumference for slicing. The tip.
   point serves to ensure that the holes created remain.
   straight and precise. The sizes available in the market today range.
   between 6-15mm. View the products in our catalog at. sini .

4. Countersink Bits are used to create holes in wood to make the surface flat. These drill bits have a 90-degree angle and are used to create holes at a 45-degree angle to the wood. Additionally, these bits are also used to smooth the edges of the drilled holes. There are various styles and sizes of Countersink Bits available depending on the project being undertaken.

   Countersink Bits yang beralur memiliki satu atau lebih tepi tajam, sementara Countersink Bits lubang silang memiliki lubang bersudut di ujungnya yang berfungsi sebagai tepi tajam. Countersink Bits satu bagian hadir dalam dua variasi utama: countersink beralur dan countersink lubang silang. Countersink beralur yang paling umum dikenal memiliki flute pendek dengan silinder memanjang di atasnya dan ujung berbentuk kerucut. Countersink beralur yang khas dahulu memiliki empat tepi tajam pada kerucut, meskipun countersink beralur satu bagian saat ini lebih umum memiliki jumlah tepi tajam yang ganjil, biasanya satu atau lima. Countersink beralur tersedia dalam berbagai ukuran dan dapat memotong lubang berbentuk kerucut yang dirancang untuk memasang sekrup dengan berbagai dimensi kepala.

   A pilot hole is first drilled for the screw, followed by a countersinking hole to allow the flat screw head to sit flush with the work surface. It's advisable to use a countersink with a body diameter that is almost the same as the screw head's diameter. Using a countersink with a diameter that is too narrow won't create a large enough countersink to accommodate the screw head, and using one that is too wide risks creating a countersink that completely swallows the screw.

   Countersink lubang silang (Countersink cross-hole) adalah jenis countersink satu bagian yang relatif baru dan tidak memiliki flute. Lubang dibuat melalui kerucut pada sudut tertentu, dan saat mata bor berputar, tepi trailing dari lubang ini menciptakan potongan. Countersink cross-hole memotong dengan sangat mulus dan menghilangkan material dengan cepat, serta sangat efisien dalam mengeluarkan serpihan saat melakukan pengeboran. Biasanya, countersink ini memiliki harga sedikit lebih tinggi dibandingkan dengan countersink beralur yang menggunakan flute.

5. Forstner bits are widely used for creating holes for hinge cups. These bits produce precise, clean holes with a flat bottom, especially if they don't penetrate through. To achieve good quality, it's recommended to use a bench drill press rather than a handheld drill, as it provides more stability. Forstner bits are optimized for woodworking applications and cut wood holes with great precision and a clean edge. They are designed to produce minimal tear-out as they exit the material, making them the best choice for drilling holes. Forstner bits bore with a flat bottom, making them essential for many hardware installations that require a precise depth. Forstner bits are guided by their wide outer rim, unlike most bits that are guided by their tip. Therefore, they can be used along with a drill press for drilling angled holes, overlapping holes, and holes near the material's edge. The 7-Piece Forstner Bit Set is a good basic set and includes the most commonly used bits ranging from 1/4" to 1". The 16-Piece Forstner Bit Set provides the advantage of having several larger-sized bits, up to 2-1/8", which can be more expensive but offer versatility.
6. Hole Saw Bits are known as "gergaji lubang" in Indonesian because of their shape, which resembles a saw with an adjustable diameter to suit different needs. Currently, they are available in the market with sizes ranging from 25-60mm.
7. Metal Hole Saw Bits, or more precisely, we might call them "hole saws," have a shape resembling a saw with an adjustable diameter. This type is commonly used for drilling holes in brass, aluminum, iron plates, and acrylic. In the category of metal hole saws, there are two different types available in the market, namely High-Speed Steel (HSS) and HSS-Co (Cobalt). HSS-Co (Cobalt) is harder than HSS, resulting in a longer lifespan in its usage. In terms of price, HSS is usually more expensive than HSS-Co.
8. Auger Bits are commonly used drill bits for boring various types of wood and other soft materials. They have a larger diameter than standard wood bits and feature a single flute design. These bits are intended for use with low-speed rotating machines. Auger Bits are highly suitable for achieving fast and accurate drilling, whether it's for creating through holes, pre-drilling for lag bolts, or drilling deep holes in wood. Their heavy-duty self-feeding tip pulls the bit through the material, allowing for quick and easy precision drilling. The combination of a straight hole, high chip removal rate, and increased speed is made possible by the low-friction flute geometry optimized with a solid center. Optimized scoring edges and precise primary cutting edges on the bit's surface result in accurate holes. They are an ideal choice for use in various construction trades, by carpenters and roofers alike, and are suitable for both soft and hard woods. These bits have a hexagonal shank system and are compatible with all drill drivers with a 13 mm chuck.
9. Flat Bit, or flat drill bit, is similar to an Auger Bit and can be used for drilling various types of wood and other soft materials. However, the difference lies in its flat shape. Flat Bit has two main sharp edges, two cutting edges, and one central point. The use of flat wood bits is not very common in Germany, unlike the wider acceptance in English-speaking countries. Flat Bit is typically used manually with a hand or on machines that rotate very slowly, and it is not recommended for use with electric power. Flat Bit is an older type of bit suitable for various applications. Although it is more economical compared to twist bits or auger bits, the holes it produces are not as smooth, and wood chips often come out uncontrollably, especially when making through holes.
10. Hinge ring This drill bit is used to make holes in wood or soft materials. Usually it is often used to make holes that have a large diameter.
11. Chisel Bit, this drill bit is typically used to create holes in square-shaped wooden materials. It is usually operated with a Hollow Chisel Mortiser machine.
12. Mortiser Bit, this drill bit is often used to create sliding holes in wood and is operated using a mortising machine.
13. Router Bits are drill bits used for creating various profiles or decorations, commonly used by woodworking craftsmen, and operated with a router machine itself.
14. For glass, as the name suggests, this is used for glass cutting and has a tip similar to a spear.
15. Hole saw metal can be used to create holes in materials made of metal and has a very wide diameter.
16. Core drill bits are usually used to create holes in materials like walls, marble, granite, and other types of stones.
