WAY OF USE

1. Choose a drill suitable for the planned hole diameter.
2. Place the stem in the drill holder.
3. Tighten the handle firmly and check the stability of the embedding.
4. Mark the center of the planned hole.
5. Stablely fix the workpiece.
6. Set low or moderate rotations appropriate to the material.
7. Apply the tip of the drill perpendicular to the surface.
8. Start drilling with gentle, even pressure.
9. Observe the markings of subsequent diameters.
10. Stop drilling after reaching the appropriate degree.
11. Withdraw the drill at low speed.
12. Remove the filings and clean the tool after finishing work.

When processing metal, it is worth using oil for drilling or other suitable cooling and lubricating preparation. It reduces heating, improves work culture and can reduce the wear of cutting edges.

⭐ Durable workmanship ensures effective work during everyday workshop tasks. ⭐

HSS steel works well in metalworking, and the gold coating reduces the wear of the work surface. Proper rotation and the use of a cooling and lubricating agent help maintain high drilling efficiency.

⭐ Easy storage protects your fixtures from loss and makes it easy to take the kit to the workplace. ⭐

The set comes with a compact case that allows you to store all three drill bits together. It protects tools during transport, limits their movement in the box and helps to keep the workshop equipment organized.

⭐ One compact set supports many tasks involving metalworking and assembly. ⭐

Step drill bits are useful for:

• Locksmithing,
• Working with thin sheet metal,
• Installing electrical systems,
• Preparing holes for cables,
• Working on metal enclosures,
• Car repairs,
• Installing ventilation components,
• Making holes in toolboxes,
• Working with profiles and structural elements,
• Enlarging existing holes,
• Making holes for rivets and bolts,
• DIY home projects.

⭐ Three most necessary diameter ranges enclosed in a practical workshop set. ⭐

• Step drill bit 4 to 12 mm
• Step drill bit 4 to 20 mm
• Step drill bit 4 to 32 mm
• Case for storage and transport
• Protective packaging

⭐ The most important information before starting work. ⭐

Q: Can existing holes be enlarged?

🟢 Yes. The conical design allows for gradual reaming of the hole.

Q: Are the diameters marked on the drill bits?

🟢 Yes. Each step has a marking for easy size control.

Q: Is the kit suitable for drill/driver?

🟢 Yes, if the device holder fits the drill shank.

Q: Is it worth using coolant when drilling in metal?

🟢 Yes. Reduces heating and helps protect cutting edges.

⭐ Choose RENEW FORCE® and make the holes you need faster, more convenient and without constant tool changes. ⭐

Three drills, a wide range from 4 to 32 mm and a practical case create a set that will be useful for every DIYer. Add it to your workshop and always have the right size at hand!
