The TOTEM FORBES Spiral Pointed Tap (SA Series), also known as a 'gun nose', 'bull nose', or 'chipdriver' tap, is engineered for efficient machine tapping operations. Dimensionally identical to a second-lead hand tap, these taps feature a cutting face ground back relative to the tap axis along the lead portion. This design optimizes the cutting action, requires less power, and pushes cut material forward to ensure the free flow of coolant along the flutes to the cutting edge.
Built with shallower flute depths for enhanced tool strength, SA series taps operate at higher speeds and are ideal for machine tapping through holes or blind holes that provide adequate clearance beyond the threaded portion to accommodate swarf.
