Pre-Machined Router Bit Setup Block - For Lock Miter Sr. Bit, 55-503

Don't fumble with router bit setup, some cutters take more time to get setup correctly. For example, getting the perfect cut from your Lock Miter router bit can be frustrating if you don't have experience with this type of bit. That's why we took the pain out of router bit setups with our pre-machined 3/4" thick blocks. Made from pre-cut high density plastic, they'll make once frustrating bit set-up a thing of the past.

Easy to use; set the height of your router bit so the 3/4" thick block matches the profile of your cutter, since the height of your bit is automatically set, you only make a few trial cuts to dial it in. Don't waste wood or time. For use with 3/4" stock only, will work with most manufacturer's bits. Checkout the helpful videos for set-block usage below.

Please note; setup blocks that come as a matched pair are not meant to be an exact fit. They are meant to serve as a height adjustment aid and / or a fence distance aid.

Nicholas C. ★★★★★

Finally, no more guesswork dialing in that lock miter bit—these blocks drop the setup time from frustrating to a few minutes. The pre-machined faces seat the 55-503 bit squarely, so my first test cut was nearly perfect out of the gate. Worth every penny if you use that bit regularly.

Ava ★★★★★

The machining is spot on—my lock miter joints came together with zero gap on the first test cut. Saves me from the usual fiddling with calipers and test passes.

Violet ★★★★★

Finally, a setup block that actually works right out of the box. It saved me a ton of trial and error dialing in the height on my lock miter bit, and the pre-machined tolerances are spot on.
