BINSTAK 90 Degree V Groove Router Bit 1/4 Inch Shank, Carbide Insert Wood CNC Router Bits for Woodworking Engraving Carving

I bought this to replace the Denali brand Amazon sells which are junk. The Denali burned up on first use just milling an 1/8" groove in pine. I bought this and it had no issues with the same groove in the same pine. This also is better since it has an insert that you can rotate or replace when it's dull. Well worth the money.

This seems like a beast. Works well and cuts very cleanly. I have not yet had to replace the blade but it seems straight forward.I’ve cut various hardwoods, softwoods, and bamboo. All edges are crisp and very little of any tear out or fraying.

I just recently bought a CNC router, and I am in the process of learning how to use it effectively. One thing I've learned from reading and watching internet videos on the subject is that engraving with a V-Bit is very cool, particularly for all kinds of sign making. Because the bit has a wide shape and angled cutter(s) on the business end, it can cut text and graphical shapes with a very cool V-shaped bottom, and can not only alter the width of the cut (by taking advantage of different cut depths), but also engrave very fine details by the use of just the very narrow tip of the cutter. There are different angles of the cutters available, The one I'm reviewing here is the Binstack with a 1/4" shank and a 90 degree cutter (45 degrees on either side of the center shank).The bit comes packaged in a plastic storage box along with a small zip-lock baggie of extra cutter-retention screws in case the one on the bit is lost during the cutter replacement process. There is also a little hex wrench tool of the correct size to enable removal and re-attachment of these screws. The cutter blade that comes installed in the bit appears to actually be a square piece of carbide, so in fact if it gets dull or damaged it can be removed and rotated 180 degrees to expose a brand-new pair of cutting edges!The bit comes encased in a silicone-like material to protect the bit from rust and damage while in transit, but this is easily peeled off so the bit can be used. There is a line circumscribed just above head of the bit (with respect to the bit held tip-side down) with an arrow pointing to it. The line marks the depth that the bit should be mounted in the router or spindle's collet to avoid damage to the shank.I'm using the bit (as mentioned earlier) in a CNC router, but it can also be used in a hand-held router to cut V-shaped grooves for other purposes than sign making. I attached a brief video clip of the bit in action on my machine (in time-lapse, of course, so nobody will have to sit through a 10-minute video). Like I said, I'm a newbie at this and made a couple of mistakes, but I'm pleased with the way my design came out. I think that the bit did a fine job cutting!

Just finished making v groove siding boards for my shed and for the price paid, this bit had zero problems even through the big knots that were in the boards that I was working with and some knots were up to 3-4" wide. Equally great that you do not need to sharpen, just loosen the bolt, spin the bit, and retighten. The main portion of the bit never wears out, only replace the cutting bits. Great cost savings not having to buy the whole assembly.

I have several products from this seller and they are cost effective solutions for my hobbyist cnc use! The rotating blades provides for decent product life before having to replace the blades.
