MIRCONA is the core business of ACT Ltd. and is the longest established Parting-off and Precision Grooving Tool manufacturer in the world!

Its patented design of carbide insert, replaceable mechanical clamp and integral shank toolholder has remained unchanged since it was launched 40 Years ago!

It can truly be said to have stood the test of time. Designed before the days of NC machines, this remarkable design of tooling has developed over the years to satisfy the demands of the latest CNC machines and the most difficult of today's materials.

Mircona offers the worlds biggest single range of precision parting off, grooving and groove turning tools. The range consists of Circlip grooving, Relief grooving, "O" Ring grooving, Internal grooving, External grooving and Face grooving, Trepanning, Axial and Annular grooving.

Over 3000 toolholders and 2000 carbide inserts are stocked in a variety of widths, grades, coatings, geometries and chip breakers and delivery is generally within 24 hours in the U.K.

Due to the immense strength designed into the integral shank it is demonstrably the Worlds Strongest Parting-off System, allowing a 3mm wide blade toolholder to part-off a 70mm diameter solid bar to centre using tool holder shank sizes from 1616mm to 3225mm square.

Essentially, MIRCONA are Specialist Toolholder Designers who due to massive investment in "state of the art" technology in DNC / CAD / CAM and Robotics are able to design and manufacture special grooving Toolholders in less than 4/5 weeks upon receipt of customers component drawings.

This rapid response and delivery gives MIRCONA customers a real commercial advantage in application areas of parting off and grooving problems often seemingly unachievable by the rest of the carbide tooling industry.
