Drill bit set Rittal 4050.806 – twist drill bits Ø 6.8 mm, 10 pcs

Rittal 4050.806 is a set of ten twist drill bits with a 6.8 mm diameter designed for common drilling tasks. The spiral-fluted geometry of these bits provides efficient chip removal and steady drilling performance in a range of materials. Supplied as a multi-pack, this set is intended for routine maintenance, installation work and general metalworking or construction applications where consistent 6.8 mm holes are required.

Advantages

The spiral design ensures reliable chip evacuation and reduces clogging during continuous drilling. A uniform 6.8 mm diameter across all ten pieces supports repeatable hole sizes and simplifies job planning when multiple identical holes are needed. The set covers a variety of materials typically encountered in workshops and on worksites, making it a practical choice for mixed tasks without the need to change bit types frequently.

Suitable for

• Drilling holes of 6.8 mm diameter in aluminium and non-ferrous metals
• Routine maintenance and installation tasks where a consistent hole size is required
• Working with plastics and composite materials that accept twist drilling
• General steel and stainless steel drilling in construction or metalwork when compatible drill speeds and coolant practices are used

When it may not be suitable

This drill bit set is intended for standard drilling operations; it may not be ideal for precision reaming, countersinking or applications requiring exceptionally tight tolerances. For heavy-duty production drilling in hardened or abrasive materials, specialised high-performance or coated bits may be more appropriate.

Also, if your work routinely requires multiple diameters, a single-diameter multi-pack will not replace a comprehensive assortment of sizes.

Key specifications

• Type: twist (spiral) drill bits
• Diameter: 6.8 mm
• Quantity: 10 pieces
• Compatible materials: aluminium, copper, plastic, stainless steel, steel
• Finish / colour: silver

How to use

Select a suitable drill and secure the bit firmly in the chuck. Use appropriate drill speeds and feed rates for the material being drilled: lower speeds for stainless steel and higher speeds for aluminium and plastics. Apply cutting fluid or coolant when drilling ferrous metals or when prolonged drilling is required to extend bit life and improve hole quality. Clear chips regularly and secure the workpiece with clamps or a vice to prevent movement during drilling.

What to consider before purchase

• Confirm that a 6.8 mm diameter meets your application requirements and tolerance needs
• Check material compatibility and whether coated or specialised bits are needed for abrasive or hardened materials
• Ensure your drill supports the bit shank size and chuck type

Usage recommendations

Use appropriate cutting speeds and lubrication for the material, secure the workpiece, and replace bits that show wear to maintain hole quality and drilling safety.
