Drill bit set Rittal 4050.805 — twist drill bits, 6 mm diameter, 10 pieces

Rittal 4050.805 is a pack of ten 6 mm twist drill bits designed for general-purpose drilling with standard hand and bench drills. These spiral bits are intended to make clean, accurate 6 mm holes in a range of common workshop materials. Supplied as a 10-piece set, the drills support repetitive tasks and multi-station use where consistent hole size and quick replacement are required.

Advantages

The set provides ten identical 6 mm twist drill bits, reducing downtime when bits dull or break and enabling multiple users or locations to work with the same hole size. The spiral flute geometry assists chip evacuation for smoother drilling, and the neutral finish offers easy identification and handling. Compatibility with standard drill chucks makes the bits suitable for a variety of drills used in metalworking, plastics fabrication, and general maintenance tasks.

Suitable for

• Drilling 6 mm holes in aluminium and copper
• Creating holes in plastics and composite materials
• General-purpose drilling in steel and stainless steel (light to medium duty)
• Workshop or site use where multiple identical bits are needed

When it may not be suitable

These twist drill bits are intended for general-purpose use and may not perform optimally on very hard or hardened steels, high-temperature alloys, or abrasive materials without appropriate cutting speeds, coolant, and feed control. For precision reaming, very tight tolerance holes, or production machining of difficult materials, specialized drills or tool geometries may be required.

Key specifications

• Type: Twist/spiral drill bit
• Diameter: 6 mm
• Quantity: 10 pieces per pack
• Typical suitable materials: aluminium, copper, plastic, steel, stainless steel
• Finish: metallic / silver appearance

How to use

Install a 6 mm bit securely in the drill chuck and tighten according to the drill manufacturer's instructions. Select an appropriate speed and feed for the material being drilled: higher speeds for softer materials like aluminium and plastics, lower speeds and steady feed for steel and stainless steel. Use cutting fluid or coolant when drilling metals to extend bit life and improve hole quality; clear chips regularly to avoid clogging the flutes. For accurate positioning, pilot drill or center punch before drilling when required.

What to consider before purchase

• Confirm that a 6 mm hole size meets your application and tolerance requirements
• Assess the materials you will commonly drill to ensure general-purpose bits are appropriate
• Consider using cutting fluid and appropriate speeds for metals to prolong bit life
• Plan for spare bits if performing repetitive or multi-station work

Usage recommendations

For best results, match drill speed and feed to the material, use light lubrication on metals, and replace worn bits promptly. Store the set in a dry place to prevent corrosion and keep bits sorted to maintain consistent hole quality across tasks.
