Assymmetrical drilling tools with carbide indexable inserts have been available for a long time and have their share of the market. Tools with high speed steel indexable inserts, however, achieved no considerable cost advantage to equivalent high speed steel drills. But now, we have the solution (patent applied for): Sintered PM HSS-E insert, symmetrical, one-way and with two cutting edges, leading to considerable savings in costs, even for operations where util now high speed drills have been applied. You can compare. Order GT 800 WP flyer

Advantages

• very economical, as holder can be re-used. Only the insert is replaced.
• two cutting edges and symmetrical, complete drill geometry is entirely preserved thanks to the new interchangeable insert principle (patent applied for).
• no regrinding, no recoating, as insert is "throw-away". Practically a new tool is provided without any reduction in performance.
• considerable reduction in handling and stockholding costs compared with solid drilling tools.
• many sizes - few toolholders, an interesting manufacturing option i.e. changing from small to large batch production.
• reduced friction, as the toolholder has a corrosion resistant nickel plating.
• interchangeable insert is compatible with the RT 800 WP ratio drill range, (internal coolant toolholder and carbide insert). See our tooling system T 800 - the ideal solution for changing manufacturing tasks.
