Product information
BAER HSSE Short Machine Tap 35° RSP - Rc (BSPT) 1/4 x 19
This BAER single flute tap is especially designed for use with the machine. Due to the 35° right-hand helix of the flutes, the chips are transported upwards out of the blind hole. However, spiral flutes cause an increased risk of breakage when used by hand. Therefore, care must be taken to ensure exact guidance. A machine guide is ideal for this. The tap cuts the finished internal thread in just one operation. The thread can be cut in a pre-drilled core hole and does not require any preparatory work by a taper tap (No. 1) or intermediate tap (No. 2).
