Product Description
Milwaukee Brad Point Drill Bit — 1/4 in. Diameter
Model Number: 48-15-0250
The Milwaukee 48-15-0250 is a 1/4 in. Diameter Brad Point Drill Bit — a precision woodworking drill bit engineered for accurate, clean hole boring in wood, hardwood, plywood, MDF, melamine, and wood composite materials where hole position accuracy, entry surface quality, and exit surface quality are critical requirements. The defining characteristic of a brad point drill bit is its three-point geometry: a sharp center brad point spur that establishes precise hole location on the marked center point before any cutting begins, and two outer cutting spurs that score the hole perimeter circle into the wood surface before the main cutting faces remove material from the interior. This three-point geometry solves the primary limitations of twist drill bits in wood applications — twist bits walk across the surface before engaging, produce rough entry holes with torn wood fibers at the perimeter, and exit through the back face of the workpiece with significant blow-out splintering that requires additional repair work in fine woodworking applications.
The center brad point engages the marked hole location with precision and maintains accurate bit positioning throughout the cut, preventing the bit from wandering away from the intended hole center even when drilling at a slight angle or on a surface that is not perfectly perpendicular to the drill axis. This positional accuracy is essential in cabinetmaking, furniture making, drawer and door hardware installation, dowel joinery, and finish carpentry applications where hole position accuracy directly affects the functional fit and appearance of the final assembly. Milwaukee precision-machines its Brad Point Bits to tight dimensional tolerances that hold the nominal hole diameter accurately throughout the bit's cutting life — accurate hole sizing is critical for dowel joints that must provide a snug fit, for shelf pin holes that must accept standard shelf pin hardware without play, and for bolt clearance holes that must position hardware at the correct location without excessive positional tolerance.
Depth marks machined into the bit's shank body at common drilling depths allow the operator to visually confirm hole depth while the bit is rotating in the workpiece, enabling repeatable depth control during batch drilling of multiple same-depth holes without stopping to measure each individual hole. Milwaukee brad point bits are available in sizes from 1/8 in. through 1/2 in. diameter to cover the full range of precision wood drilling needs in professional woodworking and finish carpentry applications.
