Drill bit Makita B-47503, single-piece pack, replacement bit for compatible Makita drills

Makita B-47503 drill bit supplied as a single-piece pack for users who need a compatible replacement for SDS-PLUS hammer drills. This bit is intended for drilling into concrete and other masonry materials; it features a tungsten carbide tip and a centering point to help start holes accurately. The single bit in the pack is suitable for maintenance, repair, or when a specific bit geometry is required for a task.

Advantages

The tungsten carbide tip delivers wear resistance and prolonged life when working with concrete and masonry. Its centering tip improves hole start accuracy and reduces walking on the surface. The 2‑cutter design ensures efficient material removal and consistent drilling performance in SDS‑PLUS hammer drills. Supplied as a single replacement piece, it allows straightforward on‑site bit replacement without the need to buy a multi‑pack.

How to use

Insert the SDS‑PLUS shank of the drill bit into the hammer drill’s chuck according to the drill manufacturer’s instructions until it locks in place. Use the appropriate hammer drilling mode and select a drill speed suitable for concrete or masonry. Apply steady pressure without forcing the bit; allow the hammer action and carbide tip to break and remove material. Withdraw periodically to clear dust and reduce bit heating. Replace the bit when cutting edges become worn or if performance decreases.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection, and dust mask when drilling concrete. Match drill diameter and length to the anchor or fixings being used and avoid side loading the bit to prolong its service life.
