Buying Guide for Best Circular Drill Bit For Metal

Types of Drill Bits

Circular drill bits are tools used in metalworking to drill holes into a workpiece. They come in various sizes, shapes, and materials, each suited to a particular job. The most common circular drill bit is the twist bit, which is designed to cut metal quickly and efficiently. Other types of circular drill bits include annular cutters, which are designed to create clean, precise holes; hole saws, which are used for cutting large-diameter holes; and spade bits, which are used for drilling through thick metal or wood.

Material and Quality

When shopping for circular drill bits for metalworking, it’s important to pay close attention to the material and quality of the bit. High-speed steel (HSS) is the most common material used for circular drill bits, as it offers superior strength and durability compared to other metals. HSS drill bits can also be coated with titanium nitride or cobalt alloy to increase their longevity even further. It’s important to select a bit with a good cutting edge that won’t wear down quickly when drilling through metal.

Shank Style

Circular drill bits come with either straight or taper shanks. Straight shank bits are more commonly used in hand drills, while taper shank bits are better suited for use in power drills or CNC machines. The size of the shank should match the size of the chuck on your power tool or machine so that it fits securely without slipping during operation.

Cutting Edge

The cutting edge of the bit should be designed specifically for the type of material you plan on drilling into. For example, when drilling through aluminum or other soft metals, choose a split-point tip that can create clean holes without walking across the workpiece surface. For harder metals such as stainless steel or cast iron, choose a parabolic flute design that can create smooth holes without any burrs or rough edges along the sides.

Coating

It is also important to select a bit with an appropriate coating that will help reduce wear and tear on the cutting edge during operation. The most common coatings include titanium nitride (TiN), titanium aluminum nitride (TiAlN), and diamond-like carbon (DLC). These coatings provide increased lubricity during drilling operations and help reduce friction between the bit and workpiece surface, resulting in longer-lasting performance from your drill bit.

In conclusion, the best circular drill bit for metal depends on the type of metal being drilled and the desired outcome. If drilling through thin sheet metal, a standard high-speed steel bit is typically sufficient. When drilling thicker metals or harder alloys, a cobalt or titanium-coated bit is often preferred. For larger diameter holes and deep holes, a carbide-tipped or diamond tipped drill bit is recommended. Ultimately, choosing the right circular drill bit for metal requires some knowledge of the material and application being worked with.
