SpeTool Extra Long CNC Spiral Router Bits with Up Cut 1/8 inch Cutting Diameter, 1/4 inch Shank 3 inch Extra Long HRC55 Solid Carbide End Mill for Wood Cut, Carving

Works great but gets dull fast

Worked while it lasted, it didn`t last very long. 3 uses

Im glad I went with the extra-long bit. The bit that comes with the inlay kit works well but limits you to 1/4 temples and limits your inlay depth. The longer bit allows you to use 1/2 thick templates and still cut a 1/4 deep inlay. 1/4 template allows you to get 3/4 inlays.

Love their bits but they sent me a down cut bit and I didn’t check it before cutting so I wasted a piece of plywood.

Liked the length , able to cut 3/4 material with several passes. The 1/4 inch shaft is far better than using adapters that somtimes slip

While this long shank might get you a deeper cut in some places, the 1/8 cutting portion is only 1 inch long, widens right out. So dont expect to get deep into corners/along sides because youve only got a 1 inch cut depth before the shank hits the upper wall of the material, prevents you from going deeper on the edge.

Worked well but broke after a few uses (lasted one day). Price is much too high for the quality.

In middle of cut with cnc in hard wood the bit broke where it makes the transition from 1/4 to 1/16

I dont know what these reviews are about having issues with this bit. Ive been using them cutting intricate dovetails on cnc with both vertical and horizontal orientation on my cnc through 4/4 milled exotic hardwood. I obviously need this size bit to handle that. Now I go slow and take about 8 to 10 passes over that stock, but it works wonderfully. Im on my 3rd bit, because Id say I average about 4 dovetail boxes a week, over 6 months. My first bit is rough, but hasnt broke, and I still use it for roughing or test pieces cuts, and my newest one for the higher exotic exotics. So it cant be that I got lucky with a good lot of bits since Ive ordered more over time. Only thing that makes sense to me and from what I see from other reviews is they dont understand feeds, speeds, and depth per cut. Simple if you understand tha you wont have problems
