"The improved Unibit step drills will make pros' jobs easier through faster drilling with minimized vibration and greater control." Unibit's new SpeedPoint tip allows faster starts and penetrates six times faster than before.

Unibit step drills are made of industrial grade high-speed steel for long life. Users are able to drill up to 13 different hole sizes from one drill bit, with laser marked sizes for easy identification. The product's 3-flatted shank resists slippage. Titanium nitride (TiN) coating, available on several Unibit step drill sizes, causes less friction for up to six times longer life.
