We manufacture the well respected and established Robert Charles brand of countersinks. Our countersinks are manufactured using HSS-E with 5% Cobalt which gives a much longer tool life when compared to normal high speed steel.
Our piloted countersinks are widely used in the aerospace, motorsport, marine and general engineering industries. Made to the highest standard with HSS-E 5% Cobalt steel as standard for a longer life.
These are manufactured to DIN standards to suit most metric cap screws. We also offer an imperial range manufactured to suit British and US standard cap screws.
