Machine Taps with Weldon Shank
The GWB series HSS machine taps are designed for precise and efficient thread cutting in metalworking applications. Manufactured according to DIN 376 Form B, these taps ensure high accuracy, durability, and reliable performance in industrial environments.
Equipped with a Weldon shank, they are perfectly suited for use with magnetic drilling machines that offer tapping functionality. Up to size M20, the taps feature a 19 mm (3/4"") Weldon shank, while larger sizes from M22 onward are equipped with a 32 mm (1 1/4"") Weldon shank for enhanced stability and torque transmission.
These machine taps are ideal for cutting internal threads in steel, stainless steel, and other metals. Their robust HSS construction ensures long tool life and consistent cutting performance even under demanding conditions.
The GWB series is available in a wide range of sizes from M8 to M42, offering maximum flexibility for various industrial applications including fabrication, construction, and maintenance work.
