Frequently Asked Questions

Q: What materials can these HSS titanium-coated step drill bits cut through?

A: These HSS titanium-coated step drill bits are designed to cut through a wide range of materials including sheet metal, steel, aluminum, copper, plastic, and wood. The titanium coating and four-spiral flute design ensure clean, efficient cutting across all these surfaces.

Q: What shank size do these step drill bits use, and are they compatible with my drill?

A: These step drill bits feature a standard 1/4" hex shank, making them compatible with most cordless drills, corded drills, and quick-change drill chuck systems. The hex shank design also prevents the bit from slipping during operation.

Q: Why does a four-spiral flute design matter on a step drill bit?

A: The four-spiral flute design promotes faster chip evacuation — meaning debris and shavings are cleared away from the cutting edge more efficiently. This reduces heat build-up, helps maintain cutting precision, and extends the overall life of each bit compared to single or double-flute designs.

Q: How many bits are included in this set, and what is it made of?

A: This set includes 5 titanium-coated HSS (High-Speed Steel) step drill bits. High-Speed Steel provides excellent toughness and heat resistance, while the titanium coating adds an extra layer of hardness and durability for long-lasting performance.
