Composite Tools Lomas Engineering

Lomas Engineering Ltd design and manufacture a wide range of Special Solid Carbide and PCD tooling for various composite and exotic aerospace materials at our manufacturing facility in Sheffield, England.

All tools can be manufactured to include any of the following:

  • Special Cutting and/or Shank Diameters
  • Custom Shanks (Flatted / Threaded / Precision / Heat Shrink)
  • Special Cutting Length and/or Overall Lengths
  • Corner Radius or Corner Chamfer Configurations
  • Special Tight Tolerances
  • Internal Coolant Feed
  • Special Tool – CVD Coatings

LOMAS provide Special Grades of carbides, offering better abrasion resistance and increased tool hardness to withstand high temperatures when cutting. CVD (Chemical Vapour Desposition) Diamond coatings are also available which reduce heat and friction at the cutting edge, produce higher quality surface finish and can increase tool life by as much as ten times.

We also offer our own Special Drills designed for hand drilling, with specific cutting tool geometries for CFRP, both with excellent entrance and exit hole quality and increased tool life and feed rates.

Tools can be manufactured in 3 material choices for use on composites:
Solid Tungsten Carbide Tooling • CVD Diamond Coated Solid Tungsten Carbide • Polycrystalline Diamond (PCD)
