MAKITA B-57451 SDS-Plus HSS-TiN Metal Drill Bit 5.5 x 123 mm

Sharp Metal Drill Bit  MAKITA  B-57451  SDS-Plus HSS-TIN MD Bit Size 5.5 x 123 mm

Specifications

- Makita B-57451 is a drill bit specifically designed for metal drilling, made from high speed steel (High Speed Steel

- HSS) of high quality to ensure strength and wear resistance when drilling metal materials. This drill bit is reinforced with a Titanium Nitride (TiN) coating, which significantly extends tool life, increases abrasion resistance, and helps reduce heat buildup during drilling.                                                                                                                                                                                                                                                       Feature

High-Quality HSS-TiN Material: Made of high speed steel and coated with titanium nitride for excellent strength, heat resistance, and wear resistance, delivering a longer service life than conventional HSS drill bits.

SDS-Plus Shank: Specifically designed for use with SDS-Plus rotary hammers, allowing users to utilize their existing rotary hammer for metal drilling applications.

135° Split Point Tip: The 135-degree split point ground tip allows easier and more precise starts (self-centering) without the need for a center punch, reducing bit walking.

Excellent Chip Evacuation: The flute design enables efficient metal chip evacuation and heat dissipation generated by friction.

 Application

The Makita B-57451 drill bit is suitable for precision metal drilling using an SDS-Plus rotary hammer in rotation-only or standard drilling mode only. Do not use in impact/hammer mode.

Suitable Materials:

Steel

Cast Iron

General Metal

Plastics

Suitable for: Professional tradesmen, technicians, maintenance personnel, and DIY users requiring precision small-hole drilling in metalwork.
