## Long description

SDS‑MAX drill bit Makita B-30427, diameter 45 mm with a working length of 780 mm and an overall length of 920 mm. The bit features a six‑flute design that improves dust evacuation and drilling stability when working in concrete and masonry. It is designed for use with rotary hammers that accept SDS‑MAX shanks and is intended for deep hole drilling in construction, renovation and utility installations where long, high‑capacity bits are required.
Advantages
The six‑flute geometry enhances debris removal from the hole, reducing clogging and allowing more consistent percussion and rotation. The extended working length enables deep penetration without repeatedly changing extension pieces, while the robust SDS‑MAX shank provides secure tool engagement and efficient power transfer. The bit’s geometry is optimized for concrete and masonry materials, balancing drilling speed and bit life under heavy use.
Suitable for
 Deep hole drilling in reinforced and unreinforced concrete
 Core-style holes for anchor installation and through‑wall services
 Renovation tasks requiring long reach, such as floor‑to‑ceiling runs
 Utility and HVAC penetrations through masonry walls
Key specifications
 Tip diameter: 45 mm
 Working length: 780 mm
 Overall length: 920 mm
 Shank type: SDS‑MAX compatible
 Flute design: six‑flute for improved dust evacuation
 Intended materials: concrete and masonry
How to use
Select a rotary hammer with SDS‑MAX chuck that delivers appropriate impact energy for the material and hole diameter. Secure the drill bit in the tool according to the tool manufacturer's instructions. Position the bit at the marked drilling point and start the tool at low speed to establish the pilot seating, then increase speed and apply steady axial force while allowing the hammer action to do the work. Periodically withdraw the bit to clear accumulated dust and check progress when drilling deep holes. Follow safety procedures, use eye and hearing protection, and avoid excessive lateral force on the bit.
Usage recommendations
For best performance and extended life, use the bit with compatible SDS‑MAX rotary hammers rated for the required drilling diameter and depth. Keep the flutes clean by withdrawing the bit at intervals to evacuate dust; consider using water flushing only if the tool and site permit safe wet drilling. Replace the bit when signs of tip wear or reduced drilling efficiency appear.
