Frequently Asked Questions

Q: What materials can the SLADE HSS titanium step drill bit cut through?

A: This step drill bit is designed to cut through a wide range of materials including steel, brass, aluminium, wood, plastic, and similar hard or soft materials. The titanium coating and HSS 4241 construction make it effective across multiple material types.

Q: What is the difference between the 4-32mm and 4-42mm versions?

A: Both versions start drilling at 4mm and step up in increments — the 4-32mm model reaches a maximum hole diameter of 32mm, while the 4-42mm model goes up to 42mm. Choose based on the largest hole diameter you need for your project.

Q: Will this step drill bit fit my standard power drill?

A: Yes. The bit features a round, 3-sided anti-slip shank that fits securely into standard keyed and keyless drill chucks. The triangular shank design prevents slipping during operation for safer, more accurate drilling.

Q: How does the titanium coating benefit drilling performance?

A: The titanium coating significantly reduces friction between the bit and the material being drilled. This lowers heat generation, reduces wear on the cutting edges, and extends the overall lifespan of the bit — meaning more holes, more accurately, for longer.

Q: Are the step sizes labeled on the bit?

A: Yes. Each step on the drill bit is clearly engraved with its corresponding diameter measurement, making it easy to drill to a precise depth or hole size without needing additional measuring tools.
