I'm a big fan of spiral flute taps and torque limited electric drivers. You have to work hard to break a tap with that setup and seeing the swarf curl up out of the hole in three contiguous strips makes me happy.... |

I'm with PK on this. I now only buy spiral flute taps if at all possible. This doesn't mean that I no longer use my extensive range of conventional taps, as I have them covering most families of threads, but new one are spiral flute. Excellent for blind holes as the Swarf comes out backwards rather than being packed up a blind alley. Note: There are spiral flute taps, and spiral point taps, and suppliers (particularly on eBay) confuse the two. The spiral point ones are also very good, and considerably more robust than a conventional tap. |

DOH. :doh: Picture of the "sticker" above was from beta print....it has an error. Finally I have by taps in order and I put 20 boxes on one tool chest tray. I'm in for spiral taps too. Although one more complication: There is a model that pushes the swarf down! Nice when you do trough holes and front side matters. Pekka |

They do work exceedingly well, though, and if I have a choice when I buy taps, that's what I buy (no-one does a spiral flute/point left-hand 1/2" UNC* though, for some bizarre reason.) * I may have the size wrong, going from memory... |
