HQMaster Spiral Router Bits Down Cut 1/4 inch Shank Solid Carbide Nano Blue Coated Spiral Downcut CNC Bits End Mill for Wood Cut Carving Engraver (1/8 Cutting Diameter)

Good bit, does what I need it to do and worth the price, will buy more in the future.

This is a great end mill for doing 3d cutting. Makes nice clean cuts leaving a nice finish. The price makes this even a better value. Time will tell but so far this has been my goto bit for 3d cuts. Comes packaged well and arrived quickly. I will buy more of these bits

Item reviewed: HQMaster CNC Router Bits 1/4 inch Shank Ball Nose End Mill with Nano Blue Coating Spiral CNC Bits for Wood Cut Carving Engraver Side Milling End Milling Finish Machining (1/8 Cutting Dia.) This is a nice bit a a reasonable price. I prefer when smaller tip bits have a good 1/4 inch shaft at the top as this one does. Seems to me that gives it a better chance of survival in the CNC jungle. I havent figured out my long term bit storage solution, so for now most bits stay in whatever storage solution they come with. This one gets extra points for having a nice plastic case (similar to many other bit cases) with large clear lettering identifying the bit (not so common). Highly Recommend

These inexpensive router bits are great. They cut well for my needs. Im not a professional that uses it everyday but for my occasional use it sharp and cuts clean. The ball upcut works great with my plunge router. Nice to be able to scribe lines in wood beauty panels. Quarter of the cost of premium bits.

HQMaster’s 1/8-inch carbide ball nose end mill with nano blue coating and 1/4-shaft is a well-made and sharp bit. The nano blue coating improves the heat performance of the bit, and the 1/4-shaft adds rigidity. Both features will increase the life of the end mill. The bit comes packaged in a typical rectangular plastic box. The bit itself comes without any markings on it shaft. I much prefer that the end mill be labelled to allow easy identification and to prevent tool mix-ups. This is a good workhorse type end mill that I will find a lot of use for.

Tested in mild steel. The cut was very smooth as the bit is very sharp. Should work well in many materials. After testing I used a 1/8 drill to check the size. The naked eye said it was a little large. Was it runout from my setup ? Bent bit ? Manufacturing defect? I checked with a micrometer and found the bit measured .126 Probably not a really big deal in most cases. I will call it a quality control issue. Or maybe when these are sent to us vine reviewers we get the ones that didn’t pass quality control. Might just be the perfect size for some project.

Works great

The quality is fantastic and I use 1/4 more than any other and do tend to wear on them. These hold an edge well and have been put to great use cranking out holiday gifts. I cant think of an argument to pay more when this quality stands up to other really expensive options Ive tried. Update: This bit continues to hold an edge well after dozens of operations through hardwood at pretty aggressive settings of speeds. These are a fantastic workhorse bit to use.

Great bit nice and sharp measured to meet specifications. I like the way these bits cut nice and clean.

This is an excellent bit that will help you to get the cnc results your after time and time again! Pros: 1. Excellent engineering minimizes chance of shearing 2. Bluing helps with rigidity and overall performance 3. Reasonably priced 4. Durable and long-lasting bit Cons: 1. The bit doesnt come with any markings, making identification more difficult when not in its case.
