Satnam Manufacturing Tools

• Coventry die heads and copies thereof (Rubometric, OSG etc) are the most commonly used thread cutting die heads.
• They are reliable, hard wearing, simple to set and use, and can be used on manual or automatic ( and CNC) machinery.
• Maintenance and repair can be easily carried out in house, chasers are cheap and thread changeover is fast and easy.

• Very similar to the original C Style but the shank is separate to the rear of body.
• Can be used on all manual machinery, popular with model makers.
• Not really suitable for automatic machinery as little spring loading to assist head onto work piece.
• Threaded spare parts (screws etc) are expensive due to use of non standard threads.

• Shank sprung to body making it ideal for automatic machinery.
• Adjustment by two socket screws.
• Most popular Style of Coventry die head

• Fitted with external trip to open die head at end of thread. This is to overcome a problem that can occur with C, CH & CHS die heads when cutting short threads in soft materials.

• Can be operated in 'pull off' mode same as other heads.
• Designed for automatics so fitted with spring band closer.

• Robust in Construction
• High Performance
• Longer Service Life
