MAKITA B-57940 SDS-Plus Nemesis II Rotary Hammer Drill Bit 5.5 x 115 mm

Drill bit MAKITA  B-57940  SDS NemesisII 5.5 x 115 mm
Specifications The Nemesis II drill bit, model B-57940, is specifically designed for SDS-PLUS rotary hammers. It features a solid 4-cutter tungsten carbide symmetrical head, ensuring consistently round and accurate holes. The Centering Tip allows for pinpoint precision starting, even when drilling on hard or uneven surfaces. The 4-flute design is developed to accelerate dust evacuation from the hole efficiently, which reduces heat buildup and extends the bit's service life.
