Sourcing STEP DRILLS and CUTTERS set, 6 pcs, model S-SDS6

Sourcing STEP DRILLS and CUTTERS set, 6 pcs, model S-SDS6 is a compact assortment of step drills and cutters designed for creating and enlarging holes in thin sheet materials. The set covers a range of progressive hole diameters so you can switch between sizes without changing tools repeatedly. Intended for workshop, maintenance and fabrication work, these tools are suitable for drilling in metal sheets, plastics and similar thin materials where stepped hole diameters or clean countersinks are required.

Advantages

The Sourcing S-SDS6 set combines multiple step drill profiles in a single kit, reducing the need to carry numerous individual bits. Each cutter is shaped to produce stepped hole diameters progressively, improving speed and accuracy when enlarging existing holes or creating new ones. The set offers consistent hole quality on thin materials and helps achieve uniform chamfers or countersinks where needed. Compact storage and straightforward selection make the set practical for mobile toolkits and fixed workshops alike.

Suitable for

• Drilling and enlarging holes in thin metal sheets
• Creating stepped holes or countersinks in plastic panels
• Electrical enclosure and HVAC panel work requiring multiple diameters
• Maintenance, repair and fabrication tasks in workshops

Key specifications

• Set composition: six step drills and cutters covering a range of progressive hole sizes
• Intended materials: thin metal, plastic and similar sheet materials
• Design: stepped cutting profile for sequential diameter enlargement
• Storage: compact set for organized transport and storage

How to use

Select the step drill or cutter that includes the target diameter, secure the workpiece, and mount the tool in an appropriate drill chuck or holder. Start drilling at low to moderate speed with steady, even pressure; allow the stepped profile to cut progressively through the material. For best results on metal, use cutting lubricant to reduce heat and prolong tool life. After reaching the required diameter, retract the tool and inspect the hole; remove burrs or sharp edges as needed before assembly or finishing.

Usage recommendations

Use steady speeds appropriate to the material thickness and type, avoid excessive side pressure, and keep the tools clean and lightly lubricated for extended service life.
