Sharp double ended metal drill bit  MAKITA B-29979  Size #30(3.3mm)  ( 10 pcs)
MAKITA HSS-G Double Ended metal drill bit model B-29979 is designed for versatility and long service life. The drill bit is made from High-Speed Steel (HSS) and fully ground (HSS-G), providing sharp cutting edges and high dimensional accuracy.                                                                                   

Features
- High value with 2 cutting ends: Can be used from both ends, delivering double the service life of a single drill bit.
- HSS-G quality: Fully ground to provide superior sharpness and dimensional accuracy, ideal for drilling holes that require high precision
- Accurate centering: Typically features a 135° split point (even if not explicitly specified), helping prevent the drill bit from slipping/walking when starting on metal surfaces
- Rigidity: The short overall length gives the drill bit high strength and reduces the chance of bending or breaking
 

Application
- MAKITA B-29979 drill bits are primarily used for small, fast hole drilling applications:
- Rivet hole drilling: Specifically sized for installing Rivet No. 4
- Thin sheet metal work: Used for drilling thin metal sheets such as sheet steel, aluminum, and galvanized sheet
- Maintenance and assembly work: Ideal for light industrial applications, electrical work, and jobs requiring handheld drills for drilling pilot holes
