Buying guide



Having a drill bit set enables you to work on different applications in the workshop using one of the most versatile pieces of equipment you have: your hand drill or drill press. In fact, with a drill bit set, you can do pretty much anything with an impact drill, battery- or electric-powered drill or driver and quick-change connector system. Now what separates the top rated products in the best drill bit set reviews from the ordinary ones?




Expert drill bit design


The type of material that can be drilled is determined by the bit point angle. A 135-degree angle and similar flatter points are suitable for boring holes into harder material, despite the need to make a pilot hole first to prevent bit wandering. Drilling into softer workpieces requires the use of steeper point bits, such as those with 118-degree angles. Steeper point bits can drill centeredly and also deliver a cleaner drilled and exit hole. Bits with split-tip points ensure good drilling accuracy thanks to how they do not wander off the drilling point during starts.

The best drill bit set for stainless steel comes with all the frequently used sizes for general purpose drilling that include ¼ inch, ⅛ inch and 1/16 inch. The size of the bit shank should not be larger than that of the chuck. A round shank ensures accurate centering of the bit in the chuck. A hex shank has characteristic flat surfaces that ensure a secure grip with the chuck to handle even higher torque transmission drilling. It also enables use with a quick-change chuck that is common in a cordless drill. For hammer drills that do their job with a distinct hammering motion, the ability of a slotted drive system (SDS) shank to move forward and backward is an advantage.



Reliable bit construction


The drill bits in the set should be made of material and finish that will ensure long life and dependable performance under stress. Softwoods can be drilled using steel bits, which can dull quickly when used on hardwoods. Basic high speed steel (HSS) bits are tougher than steel ones and have higher heat resistance too. They are also able to hold their sharpness longer. Wood, PVC, fiberglass and soft metals like aluminum can be drilled using HSS bits.

Cobalt bits have extreme hardness and can dissipate heat quickly, making them suitable for aluminum and tough metals such as stainless steel. Black-oxide coated HSS bits are resistant to rust and offer a good level of durability. They come with a longer life than basic HSS bits and can handle various types of material including metal, hard and soft woods, fiberglass and PVC. Titanium-coated bits are more durable than standard HSS ones and can also stay sharp longer. They can be used to drill fiberglass, PVC, wood and metal.



Dependable performance


When using small bits, always start at a low transmission setting to prevent the bit from catching or snagging the workpiece. Apply steady, light pressure that should be sufficient enough to allow the chips to begin spiraling away from the workpiece. The drill bit should stay sharp to prevent burn out or overheating as it breaks through the other side of the hole. Faster spiral is produced with bits that feature a parabolic flute design, which provides more room to accommodate more chips.


Our recommendations:


There are plenty of choices on drill bit sets for metal. Hopefully, the buying guide above can help you make an easier buying decision. The best products on the market are also showcased below for even more help.



Mastercraft 054-3692-6


1-titanium-drill-bit-set-for-metalWith 18 bit sizes in all, this drill bit set for metal enables you to complete any project with all the necessary bits within easy access, including the most widely used one, the ⅛-inch size. The bits that are ⅛ inch and larger feature 135-degree split-tip points, which enables them to accommodate hard material drilling needs while improving drilling accuracy.

The bits do not walk from the center point of drilling especially when starting. The bits in the set are made tougher than standard high speed steel (HSS) types, thanks to the titanium coating that ensures reduced friction during the task and also boasts high heat resistance.

This ensures longer bit life and supports faster drilling speeds. The higher surface hardness of the titanium-coated bits helps them hold their sharp tip longer than basic HSS ones. Housed in an equally tough carrying case, the bits can be used for drilling fiberglass, plastic or PVC, wood and metal. They start drilling on contact for cleaner holes. Bit walking is also prevented effectively.

Craftsman 9-64085 Professional


2-craftsman-9-64085The Craftsman 9-64085 Professional drill bit set comprises cobalt bits in a wide variety of sizes from 1/16 inch to ⅜ inch.

You have the exact drill bit you need to handle any application and material, including hard metal. The bit sizes are nicely printed on the compartment that holds the bits so you can simply pick out what you need for the task. The cobalt drill bits have a distinct dull gold color and boast the ability to successfully cut through hard metals including cast iron and stainless steel, although softer materials can be drilled as well.

The cobalt element promotes greater strength of the steel material to make the bits more resistant to heat, which is extremely vital when cutting hard materials because of the high temperatures produced during surface contact. Cobalt drill bits also sharpen easily with cutting fluid while staying durable and strong. The handy carrying case facilitates hassle-free storage, organization and portability.

3-dewalt-dw1177Comprising 20 pieces of black oxide coated bits, the DEWALT DW1177 may have the most inexpensive coating but ensures you of a higher level of heat resistance, improved lubrication and more reliable protection from wearing compared to standard HSS bits.

Each drill bit is protected from corrosion because of the black oxide coating, which also prevents damage due to water for dependable durability. The parabolic flute design of the bits makes them perfect for general purpose boring into light metal, wood and plastic. This particular component ensures faster spiral because more chips are moved farther up the helix, giving more room to hold more chips in the flute.

The 135-degree split-tip point ensures easier starting and better drilling accuracy, enabling the bits to start drilling on contact. The split-tip point also prevents the bits from wandering away from the drilling point. Housed in a tough carrying case, the bits are conveniently organized into neat compartments for effortless picking out during use.
