## Summary description

Rittal 4050.813 is a set of three centering drill bits designed for creating precise pilot holes and starts for threading M5. Suitable for use with aluminium, plastic, stainless steel and steel, these centering drills ensure accurate hole positioning and improved thread quality when preparing materials for machining or assembly tasks.

## Long description

Rittal 4050.813 is a set of three centering drill bits designed to create precise pilot holes and accurate starts for threading M5. Made for use on aluminium, plastic, stainless steel and steel, this kit helps establish correct hole position and alignment before tapping. The small-diameter centering geometry reduces wandering and improves the consistency of subsequent threading operations, making it suitable for preparation work in metalworking and fabrication contexts.
Advantages
The set contains three centering drills sized for M5 threads, providing consistent hole centering and simplified setup for tapping operations. Their geometry is optimized to prevent slipping on flat or curved surfaces, which reduces the need for additional marking or spotting. Because they are specified for a range of materials — aluminium, plastic, stainless steel and steel — the drills are versatile for mixed-material workshop tasks.
Suitable for
 Preparing pilot holes for M5 threading in sheet metal and components
 Spot drilling on aluminium and plastic parts prior to tapping
 Use in light fabrication, repair and assembly work involving stainless steel and steel
 Applications where accurate hole position and repeatable thread starts are required
When it may not be suitable
This centering drill set is intended for starting and guiding taps for M5 threads and is not a substitute for full-size drilling or reaming operations. It is not designed for use as a final-diameter drill for through-holes or where larger hole diameters are required. For extremely hard or hardened tool steels, specialized drills or different cutting geometries may be necessary.
Key specifications
 Application: centering/spot drilling to start M5 threading
 Material compatibility: aluminium, plastic, stainless steel, steel
 Quantity: 3 pieces per set
 Purpose: improve thread start accuracy and prevent tap wandering
How to use
Secure the workpiece and mark the intended hole location. Use the centering drill in a drill press or handheld drill at appropriate speed for the material, applying steady, moderate feed until the center hole is formed. Remove chips and verify the center before switching to the M5 tap. When tapping, align the tap with the starting hole and proceed with standard tapping technique, using cutting fluid as appropriate for the material.
What to consider before purchase
 Verify that you need centering/spotting drills specifically sized for M5 thread starts
 Confirm compatibility with the materials you will work on (aluminium, plastic, stainless steel, steel)
 Consider whether three pieces meet your workshop usage frequency and backup needs
 Ensure your drilling equipment can hold small-diameter bits securely
Usage recommendations
Use appropriate speeds and cutting fluids for each material: lower speeds and suitable lubrication for stainless steel and steels, higher speeds for aluminium and plastics. Inspect drill tips for wear and replace the set when centering accuracy declines to maintain consistent thread quality.
