Rebar Eaters

Relton Rebar Eater Bits — Drill Through Concrete and Rebar Without Stopping

Hitting rebar mid-hole is one of the most common setbacks in anchor installation — and with a standard carbide bit, there's no clean way through. The bit stops, the job stalls, and something usually breaks. Relton's Rebar Eater was built to eliminate this problem. Its multi-tooth carbide cutting head is wider than the drill body and is designed to cut through both concrete aggregate and steel rebar in the same rotation without changing tools.

Rebar Eaters are a specialty tool for mixed-material drilling — not a substitute for standard masonry bits on clean concrete. Keep one or two on the truck for slab work. The standard RELRB series handles most anchor installation applications. The RELSRB short-body version is the right choice when overhead clearance is limited and a full-length bit won't fit the work envelope.

The Rebar Eater drills the same hole diameter as a standard masonry bit — a 1/2 inch Rebar Eater produces a 1/2 inch hole. Anchor sizing, embedment depth, and hole depth requirements are unchanged. No need to adjust your anchor order when you know rebar is in the slab.

For standard concrete, block, and brick drilling without rebar, the Masonry Drill Bits sub-category carries the full Relton SDS-Plus, round shank, and Tapcon pilot lineup. Rebar Eater bits pair naturally with wedge anchors and sleeve anchors — the anchor sizing and hole diameter requirements are unchanged whether you encounter rebar or not. The Concrete Anchor Drill Bit Chart covers bit sizing for every common anchor type. The Wedge Anchor Installation Guide walks through proper hole depth and dust-clearing procedures that apply to Rebar Eater drilling as well.
