Product Description
Milwaukee Self-Feed Bit Coarse Thread Replacement Feed Screw
Model Number: 48-28-6870
The Milwaukee 48-28-6870 is a Coarse Thread Replacement Feed Screw for Milwaukee Self-Feed boring bits — the replaceable center screw component with a coarse thread pitch for the Self-Feed bits in Milwaukee's lineup that use the coarse thread configuration. The coarse thread feed screw provides a faster advance rate per revolution than the standard fine thread version — the coarser pitch pulls the bit deeper into the wood with each rotation of the screw, producing a more aggressive self-advancing action that drives the bit forward faster in softer wood species, standard framing lumber, and green wood where the coarser advance rate matches the wood's lower resistance to penetration and results in faster overall drilling speed. Milwaukee offers Self-Feed replacement feed screws in both coarse and fine thread specifications to match the appropriate advance rate to the wood species and bit diameter being used.
The coarse thread is particularly effective in soft wood species like pine, fir, and SPF framing lumber that are the primary materials for residential and commercial framing work — the softer wood offers lower resistance to the feed screw's advance, and the coarser pitch capitalizes on this by pulling the bit through at a faster rate that maximizes drilling productivity in these materials. When the coarse thread feed screw dulls from contact with embedded aggregate, nails, or hard grain, the self-advancing action weakens and the operator must supplement with manual drill pressure — replacing the worn feed screw with a fresh Milwaukee OEM coarse thread screw restores the aggressive self-feed advance rate and the hands-off drilling productivity that defines the Self-Feed bit's performance advantage over standard auger bit designs.
See Milwaukee's replacement feed screw lineup for both coarse thread (48-28-6870) and fine thread (48-28-6880) specifications and Milwaukee's complete Self-Feed bit range for all available boring sizes.
