Materials & care

Our HSS Steel Step Drill Bit Set is made from high-grade High-Speed Steel (HSS) and features a titanium nitride (TiN) coating for enhanced surface hardness and reduced friction. To ensure the longevity and optimal performance of your drill bits, clean them after each use to remove debris and metal shavings. Store the set in a dry environment to prevent corrosion. Periodically apply a light oil coating if storing for extended periods, especially in humid conditions. Always use appropriate safety gear, including eye protection, when operating power tools.

FAQ

What materials can these step drill bits be used on?

These titanium-coated HSS step drill bits are highly effective for drilling in wood, plastic, aluminum, and various types of sheet metal.

What are the sizes included in this set?

The set includes three bits with ranges: 4-12mm, 4-20mm, and 4-32mm, all with 2mm increment steps.

Why is a titanium coating important for drill bits?

The titanium coating significantly reduces friction and heat buildup during drilling, which prolongs the life of the bit and allows for smoother, faster cuts.

Do these bits require any special lubrication during use?

While the titanium coating reduces friction, using a cutting fluid or lubricant, especially when drilling into harder metals, can further enhance performance and bit longevity.
