MAKITA B-57934 SDS-Plus Nemesis II Rotary Hammer Drill Bit 5 x 315 mm

Drill bit MAKITA  B-57934  SDS NemesisII 5 x 315 mm
Specifications The Nemesis II drill bit model B-57934 for SDS-PLUS shank rotary hammers is a professional-grade tool designed for efficient, fast, and smooth drilling in concrete and reinforced concrete. The drill bit head features a unique symmetrical geometry with a solid 4-cutter tungsten carbide head and a sharp Centering Tip, enabling precise and pinpoint spot drilling. This cross-cutter tip design prevents jamming in reinforced concrete, while the optimized 4-flute geometry helps clear dust and debris from the hole quickly, reducing vibration and increasing resistance to drill bit breakage.                                                                                                              Features
- Extra-deep drilling: Features an overall length of 315 mm and a working length of 250 mm, ideal for deep-drilling applications.
- Professional reinforced concrete drilling: Symmetrical 4-cutter head prevents jamming even when hitting rebar.
- Centering Tip: Enables accurate and stable starting without wandering.
- Precise round holes: The head geometry guarantees high-quality holes, ideal for precision anchor installation.
- 4-flute design: Provides fast, continuous dust evacuation, reducing bit wear.
- Wear Mark: Features a PGM accuracy indicator on the bit head (guarantees that the bit can still create accurate holes for anchors as long as the mark remains visible).
