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

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 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 bought this end mill for use in my cnc machine exclusively for wood milling. I use mainly bits from amana tools but occasional buy an off brand bit to try out and was pleased with how this bit has continued to cut decently after many hours. I dont think it cuts as clean as a high end bit, but its so close that Ill be buying more of these in the future.

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.

Great value for the money.

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.

Been using this bit now for three months straight. I bought this one because it was cheaper than some other brand name options and didnt want to ruin a good bit due to my inexperience. This bit hasnt given me a reason to change yet. Cuts are baby smooth through any hardwood i throw at it!

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

Very good cutter for the money cut a very clean edge and keeping an edge.

First time user of this product. Seems to work fine for my applications cutting wood and foam. Very sharp so use caution handling with bare hands.
