Twist drill bits Rittal 4050.801 set — 2.6 mm diameter, 10 pieces

Rittal 4050.801 is a set of ten 2.6 mm twist drill bits intended for accurate, small-diameter drilling in a range of common workshop materials. These spiral bits are manufactured for general-purpose metalworking and sheet operations where repeatable, precise holes are required. Supplied as a multi-piece pack, the set offers spare bits for series production, maintenance tasks, and everyday workshop use.

Advantages

The set delivers consistent 2.6 mm holes with good centring thanks to the spiral point geometry. A 10-piece pack reduces downtime by providing immediate replacements during repetitive drilling. The bits are suitable for multiple materials — including aluminium, copper, plastics, stainless steel and general steel — which makes the set versatile for mixed-material jobs. The compact diameter is useful for fine assembly work and pilot holes.

Suitable for

• Drilling small-diameter holes in sheet metal and thin plates
• Creating pilot holes for screws and fasteners
• Workshop maintenance and repair tasks requiring repeatable holes
• Working with aluminium, copper, plastics, stainless steel and steel

When it may not be suitable

The 2.6 mm diameter restricts use to small holes; it is not appropriate for larger-diameter drilling or heavy material removal. For high-volume production in hardened materials or thick plate where tool life is critical, a specialized coated or carbide tool designed for that application may be more suitable.

Key specifications

• Drill type: twist/spiral drill bit
• Diameter: 2.6 mm
• Quantity: 10 pieces
• Suitable materials: aluminium, copper, plastic, stainless steel, steel
• Colour/finish: silver

How to use

Choose an appropriate drill speed and feed for the material being drilled; lower speeds for stainless steel and higher speeds for aluminium and plastics. Secure the workpiece to prevent movement and centre-punch if needed to improve positioning. Use steady, moderate pressure and withdraw the bit occasionally to clear chips and reduce heat buildup. Replace worn bits from the pack to maintain hole quality.

What to consider before purchase

• Confirm 2.6 mm diameter meets the hole size required for your fasteners or components
• Check material compatibility for your typical tasks (aluminium, copper, plastic, stainless steel, steel)
• Consider whether a coated or carbide bit is needed for extended life in hard or abrasive materials
• Plan quantity needs — the set contains 10 pieces

Usage recommendations

Use appropriate cutting fluid when drilling metals to extend bit life and improve finish; store bits in their original pack or a drill index to protect tips and maintain performance.
