Product Description

By entering your model number, you can make sure that this fits.
MULTIFUNCTION - The 90 grit Round Coarse Blue (RCB) Holey Galahad is a great tool for quickly removing rotten wood, excess wood, bark, high spots, ridges, and chain saw cuts. It can be used on both its face and edge surfaces, leaving a coarse to medium finish on both contoured and concave surfaces.
TECHNOLOGY - Every Holey Galahad is designed to "open a window to your work" with its six-hole "see through" technology. There's no need to stop and lift the angle grinder to check your progress, and you'll be able to see the surface being sanded through the disc as it spins.
UNIVERSAL FIT - Our Holey Galahad shaping disks have a 4" (100mm) diameter x 7/8" (22mm) center hole and are designed to fit most standard 4-1/2" and metric 115mm and 125mm angle grinders up to 14,000 rpm.
QUALITY AND SAFETY - Our patented structured tungsten carbide teeth are made in a 5-step process and bonded to steel discs over the entire cutting surface, ensuring long life and low heat buildup.
MADE IN THE USA - Don't be fooled by low-cost knockoffs and copycats that break down when you need them the most, wasting your time and money. Our shaping disks are made to the highest quality standards right here in the United States, so you can rest assured!

Questions & Answers

What is the average life of these discs?

It's difficult to determine. I'm not a professional woodworker; rather, I'm a dedicated hobbyist who uses the disc to shape bowls out of large birch and spruce burls on a regular basis. Each project takes approximately three (3) hours to complete. Over the course of five days, I worked hard on the disc for about an hour each day. I have no complaints because it is still going strong. The dics do get clogged up now and then, but it's not a big deal; simply remove it from the grinder and burn the embedded word away with a small propane hand torch. With some practice, you can achieve a fairly consistent finish without a lot of dippy doodles using the course disc, which takes a lot of wood off quickly.

Is there a limit to the number of revolutions per minute that can be used?

I'm not sure what the Holey Galahad's maximum RPM is. For several years, I've been using my Galahad with my Dewalt 4 11 amp. With no issues, I used a 5 inch grinder. The grinder has a no-load RPMS of 11,000 RPMS.

What is the circumference of the disc on offer here? What size do you want it to be? 4", 4 1/2", 5", or 7" ?

They're made to fit the majority of 4-footed animals. Angle grinders in 1/2" (115mm) and European 125mm sizes. The maximum RPM is 14,000 RPM. br>All Holey Galahad discs are 4" (100mm) in diameter and have a 7/8" (22mm) center hole to fit angle grinders all over the world when seated on the manufacturer's 7/8" (22mm) arbor.

It works wonders in removing the layer of oxidized wood from inside a log cabin
3/5

I'm cleaning Popular logs in a log cabin, and it does an excellent job of removing the layer of oxidized wood quickly and without clogging the tool. Because the teeth are quickly wearing down, it does not receive a five-star rating. I've sanded with it for 5 hours, and the teeth will be ground down to the point where it's useless in another 5 hours. Wearing out a tool this quickly is expensive. To complete this project, I'd need to purchase two more of these tools, which is more than I'm willing to spend on sanding equipment. It's a great concept, but it won't last long.

The disc is good, but it clogs up a lot
4/5

  This is my third Holey Galahad disc (I also have the extreme and the corse), and while it performs admirably, it clogs frequently. It's great that I can fix these clogs with the help of my blowtorch, but I wish I didn't have to do it so frequently. It does, however, assist in the production of some incredible results.

What the hell is going on? When I buy something from King Arthur Tools, I always go through the same thought process
5/5

"Wow, this appears to be a lot of fun!" One is something I really want. Let me go to Amazon and choose one for you, ooh. That's a lot of money. I'm not sure what I'm saying. " [some time later] "This project is taking forever, and I'm blowing my budget on flap discs. I wish I had bought that tool from King Arthur Tools a long time ago. " [two days later, after a trip to Amazon] "Holy cow!" THIS IS EXTREMELY EXTREMELY EXTREMELY EXTREME I can't imagine being able to work without one! "br>br>This is a true story.

This is a really good back scratcher! The disc appears to function properly, but there are clearly some manufacturing flaws with it
4/5

Right out of the box, there were teeth that were knocked off or were sideways and then painted over, which was disappointing given the unit's price, but I don't believe it had a significant impact on overall functionality. Because this isn't a finely honed plane iron, a few nicks here and there aren't disastrous. So far, I've only used it once, to shape a black walnut chair seat. It removed material quickly, and despite its inherent barbaric nature, I was able to maintain a good level of control. I think the whole proprietary luck nut thing is ridiculous and needs to be resolved. Instead of making people look for the nut, it should be included with the unit or made available as an add-on in the checkout options.

It works great, but be aware of the risk of rust if you clean as instructed
5/5

This is an excellent tool. I'm going to use it to "dish out" four wooden dining chair seats. Hickory seats will be in two of the chairs, while walnut seats will be in the other two. The tool had a lot of wood embedded in it after finishing the two hickory seats. I used oven cleaner to clean it in accordance with the instructions. The embedded wood had vanished after about 15 minutes. The green paint was the same way. I figured there was no harm done, so I didn't say anything. When I went out the next morning to reinstall it on my grinder, I noticed it had begun to rust. In light of the tool's price, I'm not overjoyed. I guess I'll be storing it with a layer of oil on it.

What happened to quality assurance? I'd been meaning to order one of the disks for a while and figured I'd start with the thinnest
3/5

King Arthur's Toolkit is a unique collection of tools created by King Arthur himself. Patented Round Fine Green Holey Galahad Tungsten Carbide Disc,br>BUT the first time I turned it on, I was taken aback by the noticeable vibration! I tested it at every speed from 1 to 4, and it was only at 3- that it became obvious. 4 that you'll be able to use this disk in some way. It is severely deformed, with a rotational deviation of about 1 mm, making it unfit for use! The disc is simply bouncing off the tree's surface! Is the plant's quality control really non-existent - After all, a deformation of this magnitude is unmistakable! After a few minutes of work, this is how the disk looks! The skew is so obvious that it's hard not to notice it. I have no idea how to use a disc like that. I have discs from a competitor's company that are far superior in quality! I did not expect the product to be of such poor quality, and I cannot recommend it to other woodworkers.

Shapes wood like no other tool you've ever used
5/5

Shapes wood like no other tool you've ever seen! (If you've never used a tool like this before) It moves material at a breakneck speed, and the holes allow you to see what you're doing in real time. I've used a similar product before that didn't have the holes and it worked perfectly. But I was overjoyed when I got this one and could see what I was doing as I was doing it. These tools can be extremely dangerous, but being able to see your work reduces the risk of an accident even more. This is the tool for you if you need to move wood quickly and precisely. It will require some finishing work, but the time saved will more than compensate for the work that remains after using this Holey Galahad! br>br>To summarize, this is a fantastic tool for the money. It did exactly what it said it would do. The amount of tooth wear has been minimal, so I expect it to last a long time; if this one ever wears out, I'll definitely buy another. Unfortunately for the creator, I doubt it will ever happen! Great product, reasonable price, and on-time delivery (7-day). 10 days.

The carving head is extremely nice
5/5

This cutter performs admirably and is extremely long-lasting. I was concerned because some reviewers mentioned broken teeth, but after extensive use on hardwoods such as white oak, black walnut, hard maple, and beech, I am unable to confirm this. All of my cutter's teeth are still present. It does a great job of removing material quickly, but you should let it do its thing rather than forcing it into the wood. The cutter will last much longer as a result of this, and you won't have to worry about kickbacks.
