MAKITA B-29985 Double Ended Metal Drill Bit #20 (4.1 mm)

Sharp double ended metal drill bit MAKITA B-29985  Size #20(4.1mm) (10 pcs)
The most important feature is being a double-ended drill bit, meaning when one end becomes dull, broken, or damaged, users can immediately flip it over to use the cutting edge on the other side without wasting time changing to a new bit, significantly reducing work interruptions.                                                                                                                                                  

Features
- 2x service life (Double Ended): Features cutting edges on both ends, extending the service life per drill bit and delivering great cost-effectiveness
- HSS-G precision: Fully ground process provides higher sharpness and dimensional accuracy than rolled drill bits
- Fast hole starts: High-quality HSS-G drill bits typically feature a 135° split point, which enables hole starting without slipping/walking
- High strength: Thanks to its short overall length, it offers high rigidity and great resistance to bending or breaking during heavy-duty use
