Product Description
Milwaukee Self-Feed Bit Replacement Feed Screw — Single Ended
Model Number: 48-28-6880
The Milwaukee 48-28-6880 is a Single Ended Replacement Feed Screw for Milwaukee Self-Feed boring bits — the replaceable center screw component that provides the self-advancing mechanism that pulls the self-feed bit into the wood under its own rotational force without the operator needing to apply sustained downward drill pressure. The feed screw is the critical self-advancing element that defines the self-feed bit's primary productivity advantage over standard auger and spade bit designs — it threads into the wood ahead of the cutting face as the bit rotates, and the screw's advancing action pulls the cutting face into the material at the rate determined by the feed screw's pitch. When the feed screw dulls from contact with hard wood fibers, embedded aggregate, or fasteners, or when the tip is damaged or broken from contact with metal embedded in the wood, the self-feed mechanism loses effectiveness and the operator must supplement with manual drill pressure to maintain penetration rate — eliminating the ergonomic and productivity benefit that the self-feed design provides.
The single-ended format of the 48-28-6880 replaces the feed screw's standard tip when one end is worn or damaged, extending the life of the feed screw component before full replacement is required. Milwaukee precision-grinds the feed screw tip to the correct thread geometry and pitch for effective self-feed action in wood — an imprecisely formed replacement feed screw would either advance too aggressively (causing the bit to overdrive and bind) or too slowly (failing to provide effective self-feed action that reduces manual pressure requirements). The replacement feed screw fits Milwaukee self-feed bits that use the replaceable screw design, allowing the operator to restore full self-feed performance at low cost rather than replacing the complete self-feed bit body when only the feed screw has worn.
See Milwaukee's self-feed bit and accessory lineup for replacement feed screws in additional configurations and for the complete range of Milwaukee self-feed bits for all hole sizes from 1 in. through 4-1/4 in.
