Brad Point BitEdit
Brad Point Bit is a woodworking drill bit designed to deliver accurate, clean holes in wood by featuring a sharp center point and cutting spurs that preload the cut around the hole. The combination helps prevent wandering, reduces tear-out when used with proper technique, and makes this bit a staple in both professional shops and serious hobby work. In practice, it sits alongside other drill bit families such as twist drill bits for general purpose drilling and Forstner bits for flat-bottom holes, but its design makes it especially well-suited to precise, clean holes in softwood and hardwood alike. The bit is commonly available in a range of sizes and is produced in materials such as high-speed steel and carbide-tipped variants, reflecting a practical emphasis on durability and reliability for everyday use in woodworking.
History
Brad point bits emerged as part of the evolution of drill bits aimed at reducing wood tear-out and guiding accuracy in carpentry and joinery. While many companies contributed to their development, the format became popular in mid- to late-20th century woodworking catalogs and tool rooms, where professionals sought a dependable solution for drilling pilot holes and workpiece holes without wandering. The design analogy—center guidance paired with cutting spurs—reflects a pragmatic approach that values repeatable results in shop floors that prized efficiency and craftsmanship. For broader context on how these tools fit into the overall lineage of cutting tools, see the history of drill bits and the way drill bit technology has diversified to serve different materials and finishes.
Design and operating principle
A Brad Point Bit is built around a central guide point that sits ahead of the main cutting edges. This center point acts as a locator, aligning the bit with the exact spot where the hole is desired, which minimizes drift on initial contact with the workpiece. Flanking the tip are two spurs or cutters that score the wood around the intended hole, creating a clean edge as the bit is advanced. The main cutting lips remove material to form the hole, and the shank accepts standard driving methods, whether in a hand drill or a drill press. Brad point bits are typically offered in high-speed steel (HSS) for general use and carbide-tipped variants for longer wear under tougher wood species. They are particularly favored when drilling into hardwood or when a neat, visible hole edge is desirable for joinery such as dowel or screw placements.
In contrast to general-purpose twist drill bits, which rely more on cutting action alone and can wander on rough or irregular surfaces, brad point bits rely on the center point and spurs to establish a defined entry path before the main flute engages. This makes them a natural choice for tasks like drilling pocket holes, hinge mortises, or pilot holes for dowels, where precision matters. For users tackling large or flat-bottom holes, alternatives like Forstner bits may be preferable, but for many common woodworking tasks the brad point’s geometry offers an efficient balance of speed, accuracy, and edge quality.
Use and technique
When using a Brad Point Bit, clamping the workpiece to a stable surface and using a backing board helps further minimize tear-out on the far side. A steady feed rate and moderate cutting speed can extend tool life and maintain hole quality, especially in hardwoods. For deeper holes, it’s common to drill a pilot hole first with a smaller brad point bit to reduce skipping and wandering. Lubricants are rarely necessary with wood, but keeping the bit sharp is important; dull bits tend to chatter and produce ragged edges. After drilling, removing the workpiece and inspecting the hole edge for any residual tear-out is a practical step, particularly in precise joinery.
Brad point bits are versatile for use in both hand-held drills and drill presses. In a drill press, the bit’s guide point helps maintain alignment as the workpiece is clamped and fed vertically, which is especially valuable for cabinetmaking, furniture assembly, and cabinetry where multiple holes must line up precisely. For those who rely on traditional shop methods, the Brad Point Bit represents a straightforward, durable tool that complements a Craftsman-like approach to problem-solving in the workshop.

Variants and related tools
Variants of the Brad Point Bit include carbide-tipped versions designed to resist wear when drilling particularly dense hardwoods or finishing-quality holes. Some bits include coatings or special geometries to optimize cut quality in specific species of wood or to extend life in high-use environments. While Brad Point Bits are excellent for wood, specialized tasks may call for other families, such as the flat-bottom holes produced by Forstner bits or the general-purpose action of twist drill bits.
In shop practice, selecting between brad point, Forstner, and twist bits often comes down to a balance of hole geometry, speed of work, and cost considerations. Advocates of traditional, shop-floor practicality favor brad point bits for their reliability and clean edges, while others may argue that modern composites or particular joinery tasks justify investing in a broader set of bit types to handle a wider range of materials and hole shapes. The decision often reflects a philosophy that prioritizes tangible results, durability, and the ability to complete tasks efficiently in a smaller shop or home workshop.
Maintenance and care
Keeping Brad Point Bits sharp ensures dependable performance and clean holes. After use, wipe away wood residue and store bits in a protective case to prevent nicks on the cutting edges. Inspect the center point and spurs for wear or damage; dull spurs can compromise hole quality and increase tear-out. If sharpening is necessary, follow manufacturer guidance or professional sharpening services, keeping the bit’s geometry intact to preserve its guiding and cutting action. Proper maintenance is part of a broader attention to tool longevity that reflects a practical, workmanlike approach to tool ownership and shop efficiency.
