## Long description

Rittal 4050.809 is a set of five twist drill bits with a 10.5 mm diameter designed for general-purpose drilling in workshop, maintenance and production environments. These spiral drill bits are intended for use with compatible handheld or bench drills and are suitable for drilling a range of materials including aluminium, copper, plastics, stainless steel and steel. The 5-piece set provides spare bits for repetitive tasks and on-site repairs, helping to maintain workflow continuity.
Advantages
The Rittal 4050.809 drill bit set offers consistent 10.5 mm hole size across all five pieces, enabling repeatable results when producing holes of that diameter. The twist (spiral) geometry supports efficient chip removal and stable drilling performance across both metals and non-metallic materials. Supplied as a small multi-pack, it reduces downtime by having replacements ready when a bit dulls or breaks.
Suitable for
 General metalworking: drilling holes in steel, stainless steel, aluminium and copper
 Maintenance and repair tasks requiring a 10.5 mm hole
 Light to medium woodworking applications using compatible drill speeds
 Plastic fabrication and modification where a clean round hole is required
 Production environments where identical hole diameters are needed repeatedly
When it may not be suitable
This 10.5 mm drill bit set is intended for general-purpose drilling and may not be suitable for precision applications requiring specific tolerances, special coatings, or carbide-tipped bits. For high-volume industrial drilling, very hard alloys, or materials requiring coolant systems and specialized geometries, a different grade or coated drill bit may perform better.
Key specifications

 Diameter: 10.5 mm

How to use
Select a compatible drill or drill press with a chuck that accepts the 10.5 mm shank. Secure the workpiece and use appropriate clamping to prevent movement. Choose an appropriate drilling speed and apply steady pressure; reduce speed and use cutting fluid when drilling harder metals such as stainless steel. Replace bits from the set when they show signs of wear to maintain hole quality. Follow safety precautions including eye protection and hearing protection as needed.
What to consider before purchase
 Confirm your drill chuck accepts the 10.5 mm diameter.
 Check material compatibility for your intended drilling tasks (metals vs. plastics or wood).
 Decide if you require coated or carbide bits for increased wear resistance in hard materials.
 Consider the number of spare bits needed based on expected usage frequency.
Usage recommendations
For best results with the Rittal 4050.809 set, start drilling at recommended speeds for the target material, use cutting fluid for ferrous metals, and replace bits from the set promptly when cutting efficiency drops. Store the bits dry and protected to avoid corrosion and maintain consistent performance.
