Step Drill Bit Set Forsage F-44706 — 6 pieces, stepped hole drills

Forsage F-44706 is a set of six step drill bits designed for progressively enlarging holes in thin metal, sheet materials, plastics and laminates. Each stepped hole drill combines multiple diameters in a single tool, enabling fast transitions between sizes without changing bits. The set is intended for tasks that require precise, concentric stepped holes and is suitable for maintenance, electrical, HVAC and light metalworking applications.

Advantages

The stepped design reduces tool changes and speeds up work when creating multiple bore sizes. Hardened cutting edges and spiral flutes ensure efficient chip evacuation and consistent cutting performance across a range of diameters. Compact storage of six sizes in one kit simplifies transport and reduces the number of individual drills required for on-site jobs.

Suitable for

• Drilling progressively larger holes in sheet metal and thin steel
• Making cable and conduit entry holes in electrical panels and enclosures
• Cutting holes in plastic panels and laminates
• HVAC installations where stepped openings for fittings are needed
• Light fabrication and maintenance work requiring multiple diameters

Key specifications

• Set composition: 6 step drill bits covering a range of diameters in stepped increments
• Intended materials: thin metal, sheet materials, plastics and laminates
• Design: stepped/spiral geometry for multiple diameters per bit
• Typical application: progressive hole enlargement and concentric stepped holes
• Storage: compact kit for convenient transport and tool organization

How to use

Select the step drill bit that includes the required final diameter, mount it securely in a drill chuck and position at the marked center of the hole. Start at low speed and apply steady, moderate feed pressure to allow the stepped cutting edges to engage progressively. Use cutting lubricant when working with metal to extend bit life and improve finish. Retract periodically to clear chips and maintain cooling; finish at a controlled speed for clean edges.

Usage recommendations

For best results, clamp thin workpieces to prevent vibration, use appropriate protective equipment, and match drill speed to material thickness. Replace bits that show excessive wear or chipped cutting edges to maintain hole quality and operator safety.
