Allied Machine and Engineering, a manufacturer of hole-making and finishing cutters, has added new sizes to its AccuThread T3 thread-mill line. AccuThread T3 is now available in larger UN and ISO sizes up to 1”-8 and M24x3. Machine coding for the new sizes is included in Insta-Code, Allied Machine’s online thread-mill program generator.

Targeting high-production facilities, tool and die industries and high-temperature applications, the additional AccuThread T3 thread-mill sizes create a high-quality thread without the concern of breaking the tool in an expensive workpiece. Allied designed the tool to only machine three threads at a time, which reduces pressure and dramatically increases the chances of tool survival.

The AccuThread T3 is for machining hardened or hard-to-machine materials such as stainless steel, tool steel, and high-temperaturealloys in classifications P, S, M, H, K and N.

According to Allied the advantages of the thread-mill line include: improved tool life and a more precise thread form; the ability to cut harder materials and produce deeper threads than a standard thread mill; and improved cycle time and tool life.

Among notable features is left-hand cutting, which allows the tool to climb mill while it moves from top to bottom, creating a right-handed thread. Further features include the use of three teeth that cut minimal threads all at once and reduce side deflection, along with AM210 multi-layer PVD coating.

Among industries set to benefit are aerospace, agriculture, automotive, firearms, construction, marine, mining and renewables.
