Milwaukee 48894710 HSS Red Hex Shockwave HSS 4.5mm Ground Tin Metal Drill Bit

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 deg split point and four cutting edges. The 135 deg 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.
