Milwaukee 48894709 Metal Drill SWave HSS-G Ti. 4.2mm

These impact rated drill bits from Milwaukee feature a Titanium Nitride coating which dispenses heat and makes the drill bits suitable for use also in high speed. The QUAD EDGE tip is a unique combination of 135° split point and four cutting edges. The 135° split point allows for precise and fast drilling start without walking, while the four cutting edges create smaller chips to prevent heat build up for longer life.
