Center Drill Bit

Center drill bits, occasionally known as Slocombe drill bits, are used in metalworking to provide a starting hole for a larger-sized drill bit or to make a conical indentation in the end of a workpiece in which to mount a lathe center. In either use, the name seems appropriate, as the bit is either establishing the center of a hole or making a conical hole for a lathe center. However, the true purpose of a center drill bit is the latter task, while the former task is best done with a spotting drill bit.

In the world of machining, drilling, and woodworking, centering drill bits are essential tools for accurate and precise hole placement. These specialized bits help to ensure that your drill holes are centered and straight, making it easier to create professional-quality projects. In this comprehensive review, we will explore the top centering drill bits available in 2023, providing you with detailed information to help you make the best decision for your needs.

What to Consider When Choosing Centering Drill Bits

When selecting centering drill bits, there are several factors to consider:


The material of the drill bit will have a significant impact on its performance and durability. For woodworking, high-speed steel (HSS) bits are an excellent choice, as they offer a balance of sharpness and durability. For metalworking, cobalt or black oxide-coated HSS bits provide better heat resistance and extended tool life.

Size Range

Choose a set with a versatile size range to accommodate various drilling tasks. If you work primarily with a specific material or project type, consider selecting a set tailored to your needs.

Shank Design

The shank design plays a crucial role in the stability and ease of use of your centering drill bits. Hex shanks provide a secure grip and reduce the chance of slipping, while quick-change shanks allow for rapid bit changes.

Depth Control

Some centering drill bits come with depth stop collars or other depth control features, allowing you to create countersinks or drill holes to a precise depth.
