- [DESIGN]: The two-flute design clears chips faster and allows particles to escape easily making for cleaner holes at the worksite.
- [TRI-FLATTED SHANK]: Each unibit optimally fits into power tools such as impact drill chucks securely and eliminates slip for higher efficiency of output.
- [PRECISION]: This drill bit set cuts through steel, sheet metal and other surfaces creating relatively clean holes with only a small amount of pressure and deburrs as you drill.
