Lomas manufacture a wide range of special drills for us in many production applications.

All drills produced are available in all grades of tool steels, brazed and solid carbides with various special tool coatings such as TiN, TiCn, TIALIN etc.

Special multiple diameter drills, such as Step drills and subland drills are offered, which can carry out complex drilling and countersinking operations in one production set-up.

Special double margin and drill reamers are used for the drilling of close tolerance holes in single operation.

Oil hole, coolant feed drills are manufactured with internal ducts through which liquid flows into the cutting zone. These drills are suited to deep drilling and operations which require intense lubrication.

We offer core and step core drills which are used for enlarging pre-drilled holes. The 3 or 4 flute design serves to correct both alignment and the concentricity of existing manufactured holes.
