MAKITA B-57445 SDS-Plus HSS-TiN Metal Drill Bit 5 x 116 mm

Metal Drill Bit  MAKITA  B-57445  SDS-Plus HSS-TIN MD Bit Size 5 x 116 mm

Specifications

- Makita B-57445 is a specialized drill bit for metal drilling, made from High Speed Steel

- HSS), which is the standard for general metal drilling. This drill bit features Titanium Nitride coating (Titanium Nitride

- TiN), a gold coating that increases surface hardness, reduces friction, and provides excellent heat resistance, giving the drill bit greater wear resistance and a longer service life than conventional HSS bits.                                                                                                                                                                                                              Features

High-Quality HSS-TiN Material: The TiN coating significantly increases wear and heat resistance, extending service life and making it suitable for high-speed drilling tasks.

SDS-Plus Shank for Rotary Hammers: Enables quick and secure bit changes, ideal for use with rotary hammers in rotary-only drilling mode.

135° Split Point Tip: The sharp split point ground tip enables easy starting and high precision (Self-Centering), reducing slipping and eliminating the need for a center punch.

Efficient Chip/Heat Evacuation: The efficient flute design aids in clearing metal chips and dissipating heat generated during drilling.
