Excellent standard tools for efficient internal machining of plastics
Excellent standard tools form the basis for process-safe and efficient work flows in the internal machining of plastics. Standard tools are cost-optimized to purchase and operate reliably according to our quality standards. For internal cutting of plastics, only the sharpest tools are suitable, which is why Dieterle Special Tools provides high-quality standard tools for lathes or milling machines.
Individual custom tools for complex contours
When contours are complex, we recommend custom-form or special tools for internal plastic machining. Thanks to long tool life in plastic cutting, the higher upfront costs quickly pay off through shorter machining times.
Special Tools for Internal Machining of Plastics
Drills for plastics machining
Specified polymer geometry, excellent cutting performance, stabilized cutting edges, high rotational accuracy, improved positioning accuracy and hole quality – special drilling tools from Otto Dieterle.
Mills for plastics machining
Specified polymer geometry, optimized chip evacuation and excellent cutting performance, stabilized cutting edge, polished flute, and improved positioning accuracy.
Special Tools
The high tool life in plastic machining makes tools that machine finished contours in a single operation particularly profitable.

T303
– the ideal drill for internal plastic machining
The T303 is the right choice for drilling in plastics. As a versatile all-rounder, it is available as standard in our dimensions Ø d = 0.3 / l = 5 mm up to Ø d = 3 / l = 26 mm. For larger diameters, we recommend pre-drilling and then milling the final inner diameter to ensure short chips and a safer, more process-secure workflow.
Properties of the T303:
- Specified polymer geometry
- Excellent cutting behavior for drilling in plastics
- Stabilized cutting edges
- High rotational accuracy
- Improved positioning accuracy and hole quality

M823
– the ideal drill for internal plastic machining
The M823 is excellent for internal machining of plastics. As a standard tool, it is available in our sizes Ø d = 1 / l = 5 mm up to Ø d = 12 / l = 22 mm. For precise diameter machining, we recommend pre-drilling and then slotting (milling) to ensure short chips and a process-safe workflow.
Features of the M823 milling cutter for use in turning and milling machines:
- Specified polymer geometry
- Excellent cutting performance
- Optimized chip evacuation and stabilized cutting edge
- Polished Flute
- Improved positioning accuracy

M966
– The two-edged milling cutter for plastic internal machining
For internal processing of plastics with two cutting edges, we recommend the M966 as the standard tool. We offer it in dimensions Ø d = 0.1 / l = 0.2 mm up to Ø d = 6 / l = 18 mm. For larger diameters, we recommend pre-drilling and then milling the final inner diameter to ensure short chips and a reliable process.
- Two-Flute Milling Cutter
- Specified polymer geometry
- Polished Flute
- Improved chip removal
- More stable cutting behavior
- Improved smoothness

Internal milling standard tools for GRP / CRP
With glass fiber (GRP) or carbon fiber (CRP) reinforced plastics, which are abrasive, specialized end mills are required. For internal machining of glass- or carbon-fiber reinforced plastics, our milling tools on turning and milling machines rely on robust geometries, sharp cutting edges, and high-performance cross-tooth geometry to ensure short chips and a reliable process. To achieve longer tool life, these mills are also available with CVD (diamond) coating upon request.
M640
– Mills with cutting edge beyond center for machining of reinforced plastics
To internal milling of plastics with fillers down to the base, we recommend the M640 as the standard tool. It is available in sizes Ø d = 3 / l = 6 mm up to Ø d = 10 / l = 32 mm. For longer tool life, a diamond coating (CVD coating) is available on request.
- Cutting edge beyond center
- Fine cut type - up-cut
- Especially for the machining of abrasive materials and fibre-reinforced plastics
- 3 Machining Directions
- High performance criss-cross cutting right-hand cutting
- Also available with CVD coating

M639
– Mills for plastics with fillers
To internal milling of plastics with fillers, we recommend the M639 as the standard tool. It is available in sizes Ø d = 3 / l = 6 mm up to Ø d = 10 / l = 32 mm. For longer tool life, a diamond coating (CVD coating) is available on request.
- Medium-fine cut type - up-cut
- Especially for the machining of abrasive materials and fibre-reinforced plastics
- 3 Machining Directions
- High performance criss-cross cutting right-hand cutting
- Also available with CVD coating
