BOSS POT Taps – Spiral Point Taps are machine cutting taps from BOSS, a German thread-tool brand, developed for stable internal threading and effective chip control.
According to the BOSS catalogue, the representative configuration is Straight Flute, Form B, with Spiral Point, 4–5 Threads Chamfer. The Straight Flute combined with the Spiral Point geometry directs chips forward during tapping, making the design particularly suitable for through-hole applications.
This is the key distinction between POT and SFT Spiral Flute Taps. While SFT is designed to guide chips out of blind holes through its spiral flute, POT uses a Spiral Point to push chips forward, making it suitable for through-hole threading.
The Form B, 4–5 Threads Chamfer configuration distributes the initial cutting load across the lead threads and supports stable thread formation. BOSS classifies different chamfer forms from Form A to Form E according to hole type and machining requirements.
Efficient forward chip evacuation is particularly important in production machining. By directing chips away from the cutting zone, the POT geometry helps reduce chip packing, chip recutting and abnormal cutting torque, contributing to more stable tapping and reduced risk of tool failure.
BOSS also provides different surface treatments depending on the tool code and application, including TiN, TiCN and VAP. The catalogue shows different coating configurations according to workpiece material and machining requirements.
BOSS also offers JIS Machine Taps – Metric ISO Standard Thread DIN 13, alongside its DIN/metric range. The JIS catalogue specifically lists Straight Flute with Spiral Point configurations for JIS applications.
Tô Gia supplies BOSS POT taps according to thread size, pitch, hole type, workpiece material, chamfer, tolerance, coating and cutting conditions.
