Premium Quality: TiALN coating and M35 cobalt construction exhibit excellent characteristics, including high hardness, high oxidation temperature, strong adhesion, and a low friction coefficient.

Double Flute: A step drill with 2-flutes typically offers better chip evacuation. The larger flutes provide more space for chips to exit, reducing the likelihood of clogging and allowing smoother drilling.

Effortless Efficiency: Equipped with a tri-flat shank for better grip and reduced slipping in the chuck of a power tool. Perfect accessories for drill press and handheld drills.

Versatile Range: Covering sizes from 1/4”-1-3/8”, 3/16”-7/8”, 1/4-3/4”, 1/8-1/2” and 3/16”-1/12”, this set of five bits caters to varied drilling needs without the hassle of frequent changes, optimizing workflow and saving valuable time.

Reliable Precision: Crafted for reliability and precision, these drill bits offer unmatched performance for DIY enthusiasts and professionals across construction, engineering, and repair tasks.


118° split point design

The 118° split point design requires less pressure due to its self-centering feature, and it also prevents walking.

X-Shape Design

The X-Shaped design offers improved chip evacuation, more efficient cutting, and a faster drilling process.

TiAIN Coated

The surface of the step drill bit set is coated with a layer of TiAIN. This coating helps minimize wear on the drill bit during each drilling process.
