Hard metal Gun drills - Mechanical processing
The use of gun drills is a deep precision drilling process that uses a long and straight tool to produce extremely precise and deep holes in different materials. This tool has a particular head geometry, the standard gun drill has a single cutting edge with a groove along the tool length with internal oil lubrication. Chips and hot oil are evacuated along the tool's outer groove. This type of drill requires a pre-drilling hole with tolerance of about +0.02 deep about once the diameter.
The advantages of these hard metal tips are:
1.0 Precise tolerances as required by the customer
2.0 Excellent durability with reliable performance
3.0 Good value / efficiency / price
Outils offers a complete line of gun drills. Holes can be single, double or Kidney holes according to needs.
Deep drilling is increasingly demanded in various fields, for the medical sector, plastic moulds, die casting, thermoforming, aeronautical parts, hydraulic parts and mechanical transmissions
