The Ultimate Buying Guide for the Best Drill Bit Set in 2017
There are a dozen ways to make a hole in something. Selecting the right way means that you put the right hole in the intended place and also that you put it without damaging the material, the tool, or even hurting yourself and with the least amount of effort.
Just about anything (wood, plastic, metal, etc) can be drilled, but what you are drilling is the hardest question when selecting the best bit. Soft materials might be drilled successfully with most bits, but brittle and hard materials like acrylic and glass might require uniquely designed bits.
Therefore, here is an article that will help you choose the best drill bit set for your drilling projects.
Drill Bit Set Fabrics and Finishes
The fabrics from which bits are made and the finishes used play a vital role in the performance and life of the bit. Common fabrics and finishes used include:
- Steel bits – work well in drilling softwood, but also drill fast in hardwood.
- Cobalt bits – work well in drilling aluminum and other tough metals.
- High-speed steel (HSS) bits – work well in drilling PVC, soft metals, fiberglass, and wood.
- Titanium coated HSS bits – work well for drilling PVC, fiberglass, metal, and wood.
- Black oxide-coated HSS bits – work well in drilling metal, softwood, PVC, fiberglass, and hardwood.
- Carbide-tipped bits – work well in drilling masonry and tile.
Those are some of the main materials that are used to make a drill. Next, let us look at how to select the perfect drill bits (types of drill bits).

How to Select the Perfect Drill Bits
The kind of drill bit you require to use will depend on the type of material you want to drill.
1. Metal drill bits
These bits are used to drill different types of metal, but you can also use them to drill wood. HSS is the main material used in these bits. For harder material and long-lasting use, get cobalt or tungsten carbide drill bits.
2. Tile, glass drill bits
They look like small spears. They have a carbide tip and a steel shaft. When boring tiles and glass, use a slow speed on your drill and unfasten the hammer impact setting. Sizes for tile and glass drill bits are usually limited.
3. Concrete and masonry drill bits
They have a carbide spear joint and a steel shaft brazed into them. The ends are manufactured of impact-resistance carbide and are much thicker. The shafts and flutes are stronger to withstand harder jobs.
4. Wood drill bits
Their tips have a single central point. With an effective cutting capacity, these drill bits are also effective on all kinds of softwood, hardwood, veneer, and plywood.
5. Flat wood bits
They come in different sizes ranging from ¼” to 1 ½”. They boast of a long central point to place the bits better. They do the drilling job fast and are easy to re-sharpen.
6. Expandable bits
These bits have a middle screw area to aid pull them via the wood but with a single spur and a flat cutter. They are perfect for huge holes, but you need to keep them sharp so as to work effectively.
7. Hole saws
One of the major uses of hole saws is to drill holes in doors for security peepholes and locks. There are 2 kinds of hole saws: one with a welded steel cup design (threaded onto an arbor) and the other with spring steel cutter (for locking into an arbor).
8. Twist bits
Often called the twist drills, these bits are widely used by handymen with either an electric or hand drill. The front part cut the element and the spirals remove the remains from the hole and keep the bit straight. They are used on metal, plastics, timber, and other materials.
9. Screwdriver bit drills
These bits are made to fit in a rechargeable screwdriver and have a hexagonal stem. They are perfect for drilling sample holes but are limited by the limited size of tiny bits available and the lower power of the screwdrivers.
10. Spur point bit
They are also known as dowel or wood bit and have a middle point as well as two hoisted spurs that assist keep the tool drilling straight. This bit bores timber quite fast when used with a power drill and always leave a clean hole. They are perfect for boring holes for dowels as the sides should be parallel and clean.
11. Bullet pilot point
They resemble spur point bits and are used to drill plastics, wood, and metal. Their twisted flutes are far away from the surface, making then better, more accurate bits than ordinary twist bits. They put a clean hole and leave little damage when they cut via the back of the material.
Although it isn’t a true drill, it’s used in a hand or power drill to form the tapering nook for the heads of countersunk screws. They are designed to be used on soft elements such as plastics, timber, but not metals.
13. Forstner bit
They are used to drill holes with a flat base, like kitchen cupboard hinges. They are best used in power drills held in drill stands as there is little in the way of the central point. It is hard to position if you use them freehand as there is no middle pilot bit.
14. Wood auger bit
This is one of the best drill bit set for drilling large-diameter, thick holes in man-made boards or deep ones in wood. Often, these bits should only be used in hand braces. They create deep and clean flat based holes.
The Benefit of Drill Bit Set
One of the most well-known quotes in drill bit set marketing originated from Theodore Levitt, a professor at Harvard Business School: “Individuals do not want to purchase a ¼” drill, they want to purchase a ¼” hole!” Hence, you do not buy drill set bit, you purchase them for the hole they make. Sounds confusing, but it is the truth. You purchase these products because they make the holes you require for different purposes, not because they are drill bits.

Eventually, you are looking for a drill because it assists you makes the ideal deck for memorable gathering over the summer.
Therefore, the benefit of buying drill bit set is that they lead to a fun family gathering.
