The Groove Master Bit is built specifically for cutting board makers who want cleaner grooves with less sanding. Its 0.50" round nose tip cuts a traditional groove, but once you pass .1875" depth, it forms a built-in 45° chamfer that breaks the sharp edge automatically. This allows you to adjust your cutting depth to create larger or smaller juice grooves with the same bit. Adding more flexibility, fewer tool changes, and dramatically less sanding in your shop.

Customer photo review of Custom Inlay Builder (18"x12")

It had a few blemishes voids in the wood I wanted to fill didn’t realize epoxy would spread so far with end grain didn’t care for that but other wise it turned out good

Customer photo review of 1/8" x 1/2" O'Flute - 1/4" Shank - OF215

It cuts plastic like a hot knife through butter. I had to order one online in a pinch that was a dull dog and had to abandon the project when the CIC beast showed up! The next day.Note to future Greg when ordering bits order 2… “ 1 is none, 2 is 1 theory”

Customer photo review of TrueFlat - 1.25" Surfacing Bit - TF2125

Worked like a dream. Very true to flat and having the ability to change cutters versus purchasing a whole new bit every time allows for years of use from this one purchase. Well worth the money!

Customer photo review of TrueFlat - 1.25" Surfacing Bit - TF2125

I bought this, for one I needed a new flattening bit for my surface board and second it was cheaper than a drum sander. I need to sell a few more boards before getting that sander. This bit did an awesome job. I used it to flatten my cutting board and it left a great finish. I think I could have went straight to 120grit and skip 80. I didn’t, but sanding with the 80 was much faster than before. If you need a flattening bit this is a great bit. I’m using it in a makita router for a spindle.

I and my customers love the domino game set. However some customers have asked if I have cribbage boards. So I added to the outside of both halves a cribbage board protected with acrylic. Thank you Andy roff

Customer photo review of 30 Deg V-Groove - 3-Flute - 1/4 Shank - VSC30

Thanks to Ryan's YouTube video on doing V Carve Inlays, I have done over 40 inlay projects using your 30 degree "V" carving bits. This project below is a Floating Plaque that I just gifted to a local center that offers free services to cancer patients. It is held up by concealed magnets and anchored down at the bottom with fishing line. As they are having a fund raising event I have also donated the Marble Maze game and the spalted sycamore end grain cutting board that I purchased from CIC The Kin logo and the Welcome To Kin are V Carved Inlays and the Heart & Hands are regular Inlays. The white text is done with white wood filler. Thanks again to Ryan for his great V Bits and for sharing a lot of CNC woodworking tips to us hobbyist. Much Appreciated. Mark Barr

Customer photo review of 60 Degree V-Groove - 1/4 Shank - VCT-60

The 60 degree .5 width worked really well. I look forward in using it with other projects in the near future. It left a smooth cut where sanding or clean out was very simple. Great bit.

Customer photo review of American Flag Eagle CNC Sign Kit

I decided to set the beak and flag flush with the black portion. The stripes sit proud of the white and it looks great! Customer support was excellent when I screwed something up and needed another sheet.

Customer photo review of Complete CNC Inlay Starter Kit (12"x9")

Love these smaller end grain Inlay Kits for expanding my inlay skills plus the size is perfect for gifts or presents. Such a huge time savings buying these kits and the larger size Inlay Kits. I get these kits from CIC and they go right to my CNC. As opposed to 2-3 days of gluing, clamping , sawing, planing and sanding. Highly recommend!
