A-Tap is an all-purpose tap series designed to simplify tool management and to excel in a wide variety of materials and applications. A-Tap is made from powdered metal HSS and has OSG's patented V coating to achieve excellent wear resistance. The spiral flute series has adopted a variable helix flute design, which encourages stable chip evacuation and reduces cutting forces.
XPF & S-XPF series represents a new evolution in forming tap technology. These forming taps generate up to 50% less torque versus other forming taps, making it feasible to tap materials up to 40 HRC and sizes up to M45.
