## Summary description

Rittal 4050.803 is a set of 10 twist drill bits with a 4.2 mm diameter for general drilling tasks. Designed for use with drills, the set provides multiple identical bits for repetitive hole-making and maintenance jobs. Suitable for workshop, installation and repair work where consistent 4.2 mm holes are required.

## Long description

Rittal 4050.803 is a set of ten identical 4.2 mm twist drill bits intended for general drilling tasks. Supplied as a matched batch, these bits are designed for use with hand-held or bench drills to create consistent 4.2 mm holes in a range of common workshop materials. The set is suitable for installation, maintenance and repair environments where repeatable hole size and quick replacement of worn bits are required.
Advantages
The Rittal 4050.803 pack provides a uniform set of 4.2 mm twist drill bits, reducing downtime by allowing quick swap-out when a cutting edge becomes dull. Made for standard drilling operations, the bits cover a broad spectrum of materials including aluminium, copper, plastics, stainless steel and general steel, enabling versatile use across workshop and installation tasks. The silver finish helps visual identification and the ten-piece quantity supports repetitive work without immediate reordering.
Suitable for
 Drilling 4.2 mm holes in aluminium and non-ferrous metals
 Creating repeatable holes in steel and stainless steel for fittings and fasteners
 Plastic fabrication and panel work requiring precise 4.2 mm holes
 Installation and maintenance tasks where multiple identical bits are needed
When it may not be suitable
These are standard twist drill bits sized specifically at 4.2 mm; they are not a multi-diameter set and therefore not suitable when a range of hole sizes is required. For specialized drilling—such as masonry, tile, glass, or hardened tool steels—purpose-made bits or different geometries and coatings will be more appropriate.
Key specifications
 Type: Twist drill bits
 Diameter: 4.2 mm
 Quantity: 10 pieces
 Suitable materials: Aluminium, copper, plastic, stainless steel, steel
 Finish/colour: Silver
How to use
Install a 4.2 mm bit from the set into a drill chuck and tighten securely. Select an appropriate drill speed for the material being worked—lower speeds for stainless steel and higher speeds for aluminium or plastic—and apply steady pressure without forcing the bit. Use cutting fluid or lubricant when drilling ferrous metals to extend bit life, and clear chips regularly during longer holes. Replace bits from the set as soon as cutting performance diminishes to maintain hole accuracy.
What to consider before purchase
 Required hole diameter is fixed at 4.2 mm; ensure this matches your application
 Check whether material-specific or coated bits are needed for abrasive or hardened materials
 Confirm compatibility with your drill chuck size and intended drilling speeds
Usage recommendations
For best results, match drill speed and feed to the material, use appropriate lubrication for metals, and keep spare bits from the pack on hand for repetitive tasks to maintain consistent hole quality.
