Drill bit set Rittal 4050.804, twist drill bits, 5 mm diameter, 10 pcs

Rittal 4050.804 is a 10-piece set of 5 mm twist drill bits designed for general-purpose drilling in metal, wood and plastics. These spiral bits are intended for use with handheld drills and drill presses to create precise through-holes and routine workshop tasks where a standard twist geometry is appropriate. The pack contains ten identical silver-colored 5 mm bits suitable for a range of common materials.

Advantages

The Rittal 4050.804 drill bit set offers consistent diameter and geometry across all ten pieces, ensuring repeatable hole size and straightforward replacement in production or maintenance tasks. The 5 mm twist design provides reliable chip evacuation and stable drilling performance in softer metals, plastics and wood while remaining suitable for many steel and stainless steel applications depending on feed and speed. Supplied as a multi-piece pack, it simplifies inventory and reduces downtime when multiple identical holes are required.

Suitable for

• Drilling through aluminium and copper components
• Creating clearance and pilot holes in steel and stainless steel (appropriate speed and coolant recommended)
• Routine workshop and maintenance tasks with handheld drills or drill presses
• Working with plastics and wooden parts where a standard twist bit is acceptable

When it may not be suitable

This set uses a standard twist geometry and may not be optimal for high-performance or specialised machining such as hardened steels, precision reaming, or hole finishes requiring carbide or coated tooling. For frequent drilling of very hard materials, high-speed production, or applications demanding extended tool life and reduced friction, consider coated or carbide variants designed specifically for those conditions.

Key specifications

• Tool type: twist (spiral) drill bits
• Diameter: 5 mm
• Quantity: 10 pieces
• Typical suitable materials: aluminium, copper, plastic, steel, stainless steel
• Colour/finish: silver
• Intended use: handheld drills and drill presses for through-holes

How to use

Secure the appropriate drill bit in the chuck and tighten firmly. For metal work, use correct spindle speed and apply steady feed pressure; use cutting fluid when drilling steels or stainless steel to reduce heat and extend bit life. For plastics and wood, a slower feed and reduced speed can help prevent melting or splintering. Clamp the workpiece securely and, where required, use a centre punch to prevent wandering when starting the hole. After drilling, clear chips from the flutes and inspect the bit for wear before subsequent use.

What to consider before purchase

• Confirm 5 mm diameter matches the required hole size and fit tolerance for fasteners or components
• Assess the primary materials to be drilled; consider coated or carbide bits for frequent work on hardened steels
• Check whether a bulk 10-piece pack fits your usage rate and inventory needs
• Ensure your drill or press supports correct speed and chuck size for stable operation

Usage recommendations

Use appropriate speeds and cutting fluids for metals, secure the workpiece, and inspect bits regularly for wear. Replace bits as soon as drilling quality degrades to maintain consistent hole size and reduce risk of tool breakage.
