## Summary description

Rittal 4050.814 is a set of three centering drill bits designed for precise pilot holes and thread starts. The set supports M6 thread size and is suitable for use in aluminium, plastic, stainless steel and steel. Intended for machine or manual drilling where accurate center positioning and clean starts for tapping are required.

## Long description

Rittal 4050.814 is a set of three centering drill bits designed to produce precise pilot holes and clean thread starts for M6 tapping operations. Manufactured for use with both machine and manual drilling, these centering bits are suitable for a range of materials including aluminium, plastic, stainless steel and steel. The geometry of each bit helps position subsequent tools accurately and reduces the risk of wandering or misaligned threads.
Advantages
The centering drill bit set provides consistent centre positioning and repeatable pilot holes to improve tapping accuracy. Supplied as a set of three, the bits cover multiple replacement cycles or allow keeping one in the tool fixture while the others remain in storage. The design supports effective chip evacuation and clean starts, which reduces the likelihood of cross-threading and helps achieve reliable M6 threads across different workpiece materials.
Suitable for
 Creating pilot holes prior to M6 tapping in aluminium components
 Starting threads in plastic parts where precise alignment is required
 Preparing holes for M6 threads in stainless steel and mild steel
 Use in both machine drilling operations and manual drill presses
When it may not be suitable
This centering drill bit set is specified for producing pilot holes and thread starts for M6 threads; it is not a complete tapping tool and does not replace taps or thread-cutting inserts. For thread sizes other than M6, different centering or pilot drill sizes are required. Additionally, the bits are optimized for the listed materials—very hard alloys or heavily reinforced composites may require specialized drill geometries or coatings.
Key specifications
 Intended thread support: M6
 Number of pieces: 3
 Applicable materials: aluminium, plastic, stainless steel, steel
 Use mode: suitable for machine or manual drilling
How to use
Secure the workpiece to prevent movement and select a suitable drill speed for the material. Clamp the centering drill bit in the chuck, align it with the intended hole position and apply steady feed pressure to create a precise pilot hole. After drilling the pilot, remove chips and then proceed with the M6 tap or follow-up machining operation. Replace bits when wear affects hole quality to maintain consistent thread starts.
What to consider before purchase
 Confirm that you require pilot drills for M6 thread starts rather than taps or complete thread-cutting sets
 Ensure your application materials match the listed suitable materials (aluminium, plastic, stainless steel, steel)
 Check compatibility with your drilling equipment (machine or manual drill press chuck sizes and speeds)
Usage recommendations
Use appropriate cutting fluid for stainless steel and harder steels, maintain recommended speeds and feeds for each material, and inspect bits regularly for wear to ensure consistent, accurate M6 thread starts.
