Milwaukee SHOCKWAVE RED HELIX Titanium Drill Bit, 1/4 in. Hex Shank
The SHOCKWAVE RED HELIX is Milwaukee's titanium-coated twist drill bit for impact drivers and drills. It has a 1/4 in. hex shank that locks straight into a quick-change impact chuck, and a 135 degree split point that starts on the mark without a centre punch.
One product page covers seven fractional sizes, each a single bit. The variable helix runs from 35 degrees at the tip to 15 degrees up the flute, which clears chips quickly and keeps heat down in metal.
1/4 in. hex shank only. These bits fit impact drivers and hex-shank chucks, not a standard three-jaw chuck that needs a round shank.
Features and Common Uses
- Titanium coating for longer bit life than black oxide bits
- Quad Edge tip gives a precise start and four cutting edges that make smaller chips
- Variable helix, 35 degrees at the tip tapering to 15 degrees, for fast chip removal
- Tapered web adds strength and reduces breakage
- 135 degree split point stays on the mark without walking
- 1/4 in. hex shank for impact drivers and quick-change chucks
Commonly used for:
- Drilling pilot and clearance holes in steel, stainless steel, cast iron and aluminum
- Drilling duct and sheet metal
- Wood and plastic where an impact driver is the tool at hand
