Step drill bit DeWALT DT5030-QZ 1 pc

The DeWALT DT5030-QZ step drill bit is designed to drill and enlarge holes from 4 mm to 34 mm in a range of materials. It is suitable for use on construction steel, ferrous and non-ferrous metals, plastic and other thin-walled materials up to 3 mm. The tool combines an optimized geometry for steady penetration with a titanium coating to improve wear and corrosion resistance.

Advantages

Optimized cutting geometry reduces walking and enables faster, more precise drilling. Titanium coating increases wear and corrosion resistance and delivers up to twice the tool life compared with black oxide finish. The stepped profile allows drilling and enlarging multiple hole sizes with a single bit, reducing bit changes and setup time.

Suitable for

• Electrical installation work (conduit and junction box holes)
• Plumbing and HVAC sheet-metal penetrations
• Sheet-metal fabrication and light structural drilling
• DIY projects on metal and plastic

How to use

Secure the step drill bit in the drill chuck and set the drill to a moderate speed suitable for sheet metal or the target material. Position the pilot point on the mark and apply steady pressure; allow the optimized geometry to cut without forcing. For larger diameters, progressively advance through the steps until the required hole size is reached. Retract occasionally to clear chips and maintain cooling where necessary.

Usage recommendations

Use appropriate personal protective equipment (eye protection and gloves). For best results on thicker or harder metals, use cutting lubricant and a steady, controlled drill speed. Avoid excessive pressure to preserve the titanium coating and extend bit life.
