Infinity Tools 61-502 ミッションレール＆スタイルビットセット用セットアップブロック

The setup block made zeroing in the tongue and groove depths effortless on my first try, saving me at least 15 minutes of test cuts. It fits snugly on the bit without any wobble.

Finally, a setup block that takes the guesswork out of the 61-502 bit set — the pre-machined tolerances are spot on, so my tongue and groove joints came out dead consistent on the first try. I used to burn 20 minutes fiddling with test cuts, now it's a 5-minute job.

The tongue-and-groove bit setup was dialed in after just one pass with this block, saving me a good 15 minutes of trial cuts. The pre-machined reference faces are dead-on accurate.
