FAMAG brad point bits

This 7-piece brad-point set includes 1/8″, 3/16″, 1/4″, 5/16″, 3/8″, 7/16″ and 1/2″ bits — covering the sizes most often used in furniture making. With these, you can drill pilot holes, dowel holes, clearance holes for screws, and tackle a wide range of joinery tasks. The set comes in a durable plastic case that keeps the bits organized and easy to access. The bits are graduated in length, from 2-1/2″ for the 1/8″ size, 5-1/4″ for the 3/8″ bit (with a flute length — the spiral groove that runs up the shaft of the bit— of just over 3″) and a generous 6″ (with a flute length of 4″).

The most important feature is the brad-point tip itself. A sharp, well-ground center spur should be perfectly centered so that the bit doesn’t wander when you start the hole. Just as important are the outer cutting spurs. These need to be sharp and well defined because they score the wood fibers before the cutting lips remove material, which results in clean entry holes with minimal tear-out, even in hardwoods and veneered plywood. But, you don’t want them to be too long, as it makes them prone to breaking off.

The cutting lips are the edges that do the actual cutting once the fibers have been scored. They should be evenly ground and sharp to produce smooth hole walls. Chip removal depends on the flute design, so the flutes should be deep, polished, and properly twisted to clear waste efficiently. Poorly designed flutes can clog with chips, generate excess heat, and even burn the wood.

Material choice also makes a difference. High-speed steel (HSS), as on these FAMAG bits, are durable and handle hardwoods well because they resist heat. Carbide-tipped bits are harder and stay sharp much longer, making them ideal for abrasive materials like laminates, MDF, and composites, though they can be more brittle and they cost appreciably more. I avoid carbon steel bits as they dull quickly and produce inferior results, especially when used on hardwoods.

The overall precision of the bit is another key factor. Bits that are fully ground rather than rolled or stamped are sharper, more accurate, and less likely to drift. A straight, true shank ensures smooth rotation. A nice feature on the larger diameter FAMAG bits is that they have reduced shanks for compatibility with standard drill chucks. Finally, accuracy in sizing is crucial, especially if you are drilling for dowels or other joinery. Cheap bits are often slightly off-size, leading to loose-fitting joints. I found that all seven bits in this set produced precisely sized holes.

In summary, the bits in this FAMAG brad-point drill bit set combine a sharp, centered brad point, well-sharpened spurs, precise cutting lips, efficient flute design with premium quality steel that retains its sharpness longer than lower quality HSS or carbon steel . The result is that you get cleaner holes, better accuracy, and longer tool life.
