Makita D-46486 Step Drill Bit 1/4×4-20mm

The Makita D‑46486 Step Drill Bit is a professional accessory designed for precision drilling of multiple hole sizes with a single bit, optimized for sheet materials such as metal, plastics, and laminates. Like the D‑46470, it uses a step‑profile geometry, but the D‑46486 typically covers a different diameter range, making it suitable for electricians, installers, and fabricators who need flexibility in hole sizing without changing bits.
