Thread Cutting System (890)

Our Thread Cutters come in pairs and include a tool for exterior threads and one for cutting matching interior threads. Perfectly designed for making screw tight lids on boxes and caskets, this fascinating and practical aspect of woodturning includes a range of cutting tools that have been produced from High Speed Steel in 10, 16 and 20 threads per inch (TPI). They have been designed with a unique, enhanced helix angle specially designed for use in wood.

Sets are available in 10tpi, 16tpi and 20tpi. Sets include: Thread and Sizing Gauge & Focus on Specialist Woodturning Tools Part 3 DVD.

We are always looking of new ways to enhance our range, we listen to our customers and what they need.

With this in mind, we are pleased to introduce a new addition to the Thread Cutting System, the External / Internal 3.5mm pitch Thread Cutters, available handled and unhandled.

These new 3.5mm Thread Cutters are suitable for larger projects that do not require a fine thread, and also for woods with a more open grain. The larger pitch is also ideal to fit a turned project onto a M33 x 3.5mm lathe spindle thread.

To complement these tools, a range of optional items have been produced to provide a complete solution to thread cutting. These include:

  • Relief Cutting Tool
  • Tool Support Rest – to make forming internal threads easier
  • Thread and Sizing Gauge – takes all the guesswork out of dimensioning
  • Focus on Specialist Woodturning Tools Part 3 DVD – includes a range of projects

For those attempting their first steps in thread cutting, we recommend starting with the finer tooth pitches.
