Drag Knife

Updated: Customer service reached out after contacting through Amazon, instead of website. They were extremely helpful on getting the bent shaft replaced. Extremely happy with the product and believe the previous email issue was an anomaly.Used in production of cutting felt for a few months. Noticed circles were not meeting from start to finish point. The 1/4” shaft bent slightly, probably needs to be 1/2”. Reached out to customer service close to 2 months ago and have not heard back.

I purchased this dragknife in Sept. 2022 and here it is March 2023 and I am just getting around to using this. Part of the reason is that I was a bit intimidated to use it. Stupid me. I am using Vectric Pro with the dragknife toolpath gadget. The one thing that confused me was the setting for the blade offset. Not having any experience with this so I reached out to SST on a Sunday morning figuring that I would get a response early in the week. Well, in less than 3 hours I had my answer. GREAT customer service. Thought I would share the answer to blade offset:The offset is adjustable, so you will need to measure it in order to plug in the value to your drawknife software.Both the blade height and offset have a 1:1 ratio with each other, so in order to get the offset value you just need to measure the blade height (from blade tip, to the bottom face of the drag knife)

Since I’ve started using a CNC machine I have used a few different drag knives, this by far is the best one yet. I would recommend this product 10/10 times!

After owning a few different brands of dragknife, the overriding issue to us is how well it stands up over time. Several have small offsets and details to hold the blade, after a while it gets tough to register and keep it all in place. Not with the SST brand. You can see it hits properly on all those details, such as holding the blade depth, not letting the blade slide, and controlling the offset. This is definitely the best one we have used.

I had purchased this and right off the bat I didn't set my z on my cnc machine and ran the router sideways and down way deeper than the tool was supposed to be at by inches. I bent the tools spindle. MY mistake for sure. Called support and they mailed me out a replacement. Drag knife works great and is 1/3 the price of some of the competitors.
