SpeTool Spiral Router Bits Down Cut 1/4 inch Cutting Diameter, 1/4 inch Shank Solid Carbide CNC Bits End Mill for Wood Cut Carving Engraver

This bit worked great for cutting holes in 3/4 Baltic birch. I only cut 1/4 on each pass since I am using a palm router, but the lines are sharp and accurate. Just need to clear the dust after each pass.

I was cutting a 1/32 inch deep 10.5 inch diameter circles in ¼ inch plywood to position a second part and the cut was not clean. Purchased this spiral router bits with down cut and it cleaned up the cuts beautifully. Two factors sharp bit and spiral router bit with down cut. All directions of the grain on the wood without a problem. Needed this tool for this job.

ESTA FUE UNA REPOSICIÓN DEL PEDIDO ORIGINAL YA QUE EL PRIMERO SE EXTRAVIÓ Y AMAZON AL DETECTAR EL PROBLEMA INMEDIATAMENTE ME ENVIÓ DE NUEVO EL PRODUCTO QUE LLEGÓ RAPIDÍSIMO. PROBÉ UNA EN MI FRESADORA Y LOS CORTES FUERON GENIALES. LO RECOMIENDO

I ordered this for use in my CNC router. Had a production run of wooden pen cases to cut out (walnut and maple) and needed to order a new bit to avoid tearout. Took a chance on this one because the price was low. I wasnt expecting much, but its still very sharp after cutting for 12+ hours. Might be just a hair bigger than 1/4, as my 1/4 indexing pins were a little loose in the positioning holes that this bit drilled. Regardless, Ill order more of these for future jobs for sure. Very happy with the cut quality and tool life.

Good endmills. Plain, uncoated metal, but theyre packaged well and theyre sharp enough to slice your finger (...so Ive heard...) Good price for what they are, too. The lack of coating means they get dirty quicker, though.

Ive bought several sets of these CNC bits. We do a lot of profile cutting on a shop bot buddy. They cut cleanly and last quite a long time. And theyre much more affordable than the name brand bits. I havent had one break or prematurely wear out for reasons other than user error. Measure twice, cut once!

This has been my work horse bit for a long time and it is still going.

does the job I bought it for! Will buy again.

Down cutting bit. Very clean cut. This bit is very clean cutting and doesn’t leave a rough edge when doing cut outs on the cnc.

This was purchased for cutting a radius through laminate plastic glued to MDF board used for shop made table saw miter sled. The down spiral cut left a very smooth, clean edge in the thin plastic, exactly as desired. It also left a clean, smooth edge on the MDF and a plastic liner glued to the underside as the surface contacting the table saw. If interested, this highly accurate miter build is illustrated by the designer on YouTube. Search for Making a Super Accurate Miter Gauge.
