Tap-O-Mat - M3/M4/M5/M6 Thread Cutter/Tap to Drill-Bit Adapter

thingiverse

This is a simple adapter for M3, M4, M5 and M6 tread cutting taps to a Hex drill bit. I created it because I only have a hand drill with an HEX-Insert and did not want to buy specialised taps. I intended it to work on both sides (M3, M4 on one and M5, M6 on the other; the hex bit fits on both sides), but the one side works fine for all four types of thread taps. When clamping the part there is a lot of flex, therefore **I strongly recommend using a sturdy but flexible material like ABS or PETG**. Screws I used: - 2x M5x16 with a Hex-head - 2x M5 wing nuts Optional but recommended to fix the clamps: - 2x M3x8 countersunk
