• The preferred steel to use is high speed steel.
  • The most desirable machine speed is around 2000 rpm.
  • The material responds best to scraping using a negative rake and an under-cut tool.
  • For face turning the material go in gently with the tool until you can feel the consistency of the material.
  • For drilling holes over 200 – 300 mm deep, the recommended tool is a forstners tool.  It is designed for deep hole drilling and will give maximum swarf clearance.
  • This drill is not recommended for pen blanks and caps etc.  For this we would recommend an ordinary carbide tip drill, as it is better for long term wear resistance.
  • If the tool finish is smooth then you will only need a grey silicone paper grade 1000-12000 to get a satin finish.  However if the finish is slightly rough start with a grade of 600 and then mode up to 1000-1200.
  • For a final finish we recommend friction polish, shellawax, burnishing cream,…
