HQMaster Router Bits Straight End Mill Milling Cutter Endmill 2 Flutes CNC Cutting Carbide Tungsten Steel Straight Slot Bit, Pack of 10 (4 x 22 x 45 mm)

Used these to cut and mill some purple heart pieces for a new knife block I was making, and I needed at least 3/4" of cutting height to do it. Most of the work was cutting out the shapes, but there were also 4 mortises and 9 knife slots that had to be milled out. Snapped one bit very early in the process, but the second bit finished out the rest of the project with no issues (and no change in CNC settings), so I'm assuming that the first one had some sort of material flaw in it. I've purchased other HQMaster bits and had similar experience, so I'll be sticking with them for general use.

These are the only bits that i use.They last very well out of the bits that I have bought I have only broken one.I mainly use them on soft pine but have used them on Oak and other hardwood but I drive them extremely hard 100 ins per minute 30in/min down and .0032 each pass.They maintain their sharpness very well and I will get a production run of about 30 units per cutter. When I notice that the cut edge is becoming a little fuzzy I will change it out.As for the individual that complained that they were not 1/8 all the way down you have to have clearance down the sides of the cutter.It is not a fault of the cutter or the manufacturer it is by design.

This is a good bit with some specializations. Run this on a Shapeoko with a Bosch 1617. Feeds at 100IPM with a 3/8" DOC at full RPM. Works extremely well on thin plywood (1/4") as you do not need tape to hold the board down, since the cutter will not pull up like it will with spiral flutes. On thicker materials, such as 3/4" ply, you will wind up with a layer of compressed sawdust holding the part in place, which makes cleanup a touch more difficult, as in some instances a screwdriver is required to separate the dust from the cut, but the edge quality is extremely good. Longevity is a tad short, like most of the HQMaster bits, sometimes the bit will go 10hrs or so of straight cutting before you notice signs of dulling (rougher edges, more RPM loss when cutting, etc) and sometimes they will shatter.

Used on soft and hardwood on my X-carve cnc router with good results

These work great for 3/4” CNC cutouts. I use these in walnut, hard maple, padauk, purpleheart... they work great and are inexpensive to swap each day of cutting.

No complaints on these bits at all. They are sharp and cut through soft wood with no issues. I'm running all of my 1/8" bits at a very conservative feed and stepover but did manage to screw up on feeds on a deep cut and broke a bit. I feel this is my fault vs the bits though. Recommend if you're looking for an economical set of end mills.

My only complaint is that they are not a true .125, mine are measuring at a even .12. That extra little bit might not seem like much, but on some carvings it does make a difference. Besides that, these are my normal go to bit when roughing and doing a profile cut. Sharp and cuts nice and clean, very little if any clean up

Very strong and sharp. I had my doubts using them in a milling operation where a lot of chatter was happening. I thought for sure the bit was going to break. It did not and it also surprised me to see how sharp the bit stayed giving the amount of material I had to remove. Nice addition to my Dremel bit collection.

Buena calidad

All good :)
