This is the very best grade of HSS steel. True engineering quality.

This set of drill pieces have been fully precision ground and heat treated for extra strength and durability.

Fully ground bits are machined from a single metal bar and are far better than a normal rolled or twisted drill bit.

These have a long-lasting working capacity and use an aggressive 135° split point design.

This set also comes with a handy bespoke metal carry case so you can keep them organised in their correct and tidy positions.
