## Summary description

Set of three JOBIextra cylindrical step drill bits (model X1033) covering multiple diameters from 4 mm up to 32 mm. Designed for progressive drilling of sheet metal, plastics and thin materials, each stepped cutter enables drilling of several hole sizes with a single tool. Suitable for electrical, HVAC, metalworking and general workshop tasks where varied hole diameters are required.

## Long description

Set of three JOBIextra cylindrical step drill bits model X1033 provides a compact solution for drilling multiple hole diameters with a single tool. Each stepped cutter covers a range from small pilot holes up to larger openings, allowing progressive enlargement without changing bits. The design is intended for use in sheet metal, plastics and other thin materials commonly encountered in electrical installation, HVAC work and general workshop tasks.
Advantages
The JOBIextra X1033 step drill bit set reduces tool changes by combining several diameters into one cylindrical stepped cutter, improving workflow efficiency. Its stepped geometry enables controlled chip removal and gradual hole enlargement, which helps maintain hole concentricity and reduce burr formation on thin materials. The compact set of three bits covers a broad diameter range from 4 mm to 32 mm, making it versatile for varied on-site and workshop applications.
Suitable for
Drilling holes in sheet metal for cable glands and conduit entries
Creating clean holes in plastic panels and enclosures
Making sized openings for HVAC ducting and fittings
Quick hole resizing and pilot-to-final diameter drilling in general workshop tasks
Key specifications
Set composition: three cylindrical step drill bits covering multiple diameters
Working diameter range: from 4 mm up to 32 mm across the steps
Intended materials: sheet metal, plastics and other thin materials
Shank type: cylindrical shank for use in standard drill chucks
How to use
Mark the desired hole center on the workpiece and secure the material to prevent movement. Install the appropriate step drill bit from the set into a drill with a compatible chuck and set a moderate drill speed suitable for the material being cut. Start at the pilot diameter and apply steady, even pressure to allow the bit to progress through the steps until the required hole size is achieved. Use cutting lubricant when drilling metal to reduce heat and extend tool life, and remove burrs after drilling if necessary.
Usage recommendations
For best results, match drill speed and feed to the specific material: lower speeds for thicker or harder metals and higher speeds for plastics. Use cutting fluid on metal, clamp thin sheets to a backing board to prevent distortion, and withdraw the bit periodically to clear chips. Inspect the bit edges before use and replace the cutter if excessive wear or chipping is present.
