Do not buy this junk!
I bought this to remove a broken screw and when I used it the tool broke and most of the screw remained.
Plan on buying extra
I've used the 1/4'' a few times before I had to replace it. You really have to go SLOW and make a template guide for it. I finally broke my first one after about 5 or 6 uses of it. It is very fragile and finicky. Probably best suited for small jobs and folks with a lot of patience. If they could make this stronger, it would be much better.
Almost a 5 star but it broke.
It did most of what it was supposed to do. I got most of the area "cored" out, then tried to go a little deeper. Don't do that. The tool shattered at that point. Fortunately I was able to get the screw out and plug the hole (will never see it in the pickup cavity of a guitar), but turned into a single use tool.
Broke on first use
Unfortunately this tool broke (sheared off) on the first use, so I had to pull out a 3/4" hole saw to get everything out as the screw extractor was obliterated and stuck in the wood. I hope this product can be modified to add rigidity and durability because it is a good theory, but while a bi-metal hole saw can cut through most everything, this product was insufficient.
Not a quality product.
I purchased 4 of these today. I needed to remove a pocket screw from a piece of cherry. I bought 4 because I didn’t have time to go back if a bit broke. They got the job done. It cost me all 4 bits to do it. Most of the teeth broke on contact with the wood. Did what I needed it to do ,but will never purchase this item again unless I’m in a pinch.
This broke, both sides immediately upon engaging cherry wood. The teeth snapped off. This should be tempered steel or something stronger. Plan on returning.
I used this to remove some small broken screws from curly maple on a box I was making. I had several options and decided to give this a try. I used it in my drill press and it did a phenomenal job!
I made a snug brass dowel to fit inside the cutters to prevent crushing. They do work very well HANK
The 'Hidden Patch'
Aloha , Sine the 1/4 " fits so nice inside the 5/16" and the 5/16" fits the 3/8" hole saws , You can 'Mortise' your hole to hide a worn hole or knot hole with the smaller 'hole saw' and make a prefect patch ' sized' to mate the hole with the next larger hole saw . Then after gluing them in with a 'crazy' glue and using the same saw dust from the mortise 's cut , rub and fill any gaps . A router plane , than is used to shave down to the surface of your 'patch' . Also , don't sweet in trying to match the color of the patch , it can be made to look like a 'knot' if done with care . Aloha, Mark Baker
I had 3 screws broken off in a toilet seat and rather than replace the whole seat I took the time to research how smart people solve such problems. This brought me to the wood extractor drill bit. I read the instructions and even the reviews. Picked one of these up from the Thorton Rd store here in GA along with a scrap 1/4" dowel courtesy of the accommodating sales rep who helped me that day. Using it was a piece of cake. I followed the suggestion of placing a piece of scrap wood with a predrilled 1/4" hole on directly over the spot to act as a guide to prevent "bit dancing" and clamped it down. I set the drill in reverse and went slow and steady. Within a minute or two the broken screw was out. Nice clean hole. Setting the predrilled scrap wood over the screw also had the added benefit of aligning the bit perfectly so there was little or no chance of the bit touching the screw which would shatter the teeth of the bit.
A tool worth avoiding!
I'm a fan of Woodcraft and don't like dumping on one of the tools they sell. However this screw extractor is made cheaply of material way too soft for the task. I followed the directions to the letter and the darn thing shattered on the 4th or 5th rotation. $$ bucks gone in 2 seconds. I was drilling into soft maple - the face frame on kitchen cabinets. I'm just going to fill the broken screw hole with epoxy, make a new cabinet door and move the hinge screws to another location. Don't waste your money on this loser.
It Worked as Advertised
I broke off a #8 brass screw in some black walnut and did not have a replacement piece of wood. I had to get the screw out, so I used this tool to remove it. Given the warnings about crushing the tool by twisting the chuck key too hard, I initially did not tighten it enough and the tool was pushed into the chuck instead of cutting the wood. It takes a bit of trial and error to get the chuck tightened properly. Do it slowly a little bit at a time. I made a 1/4" hole in a piece of 1/2" plywood as noted in the directions and clamped it over the screw for a guide. Then I cut slowly to avoid overheating the tool. It is important to reverse the drill when using the tool because the teeth are designed to cut counter-clockwise. That makes the tool tend to loosen the screw rather than tighten it as it drills around it. After I had drilled around the screw, it still had not come out, but a gentle twist with a pair of pliers broke it free. I had to drill out the remaining wood from the hole because the wood did not come out with the screw. I cut a plug from a 1/4" oak dowel and glued it in the hole, and it all worked just fine. Although it appears to be somewhat fragile, this is a good tool for the occasional disaster. The reviews and hints on this web site helped a lot in figuring out how to use this. Thanks to all.
This Screw extractor worked great
Use the screw extractor to first drill a hole in a spare piece of wood. Clamp the hole you just made directly over the screw that needs to be removed and then use the screw extractor to make perfect cut around the broken screw. By using the first hole as a guide, you can easily remove the broken screw and then fill the hole with a wooden dowel to facilitate the use of another screw.
The tool bores a nice clean hole even in hard materials such as oak. It is fragile however so follow the instruction in how to chuck it up in the drill
This is a job saver. Broken screws in maple are not uncommon, but with this device, you take it out as a plug, glue in some 1/4" dowel, and then put in a new screw and you are back in business. You just need to be careful not to overtighten it in the drill or because it is hollow it will distort. I have used it twice on a bunk bed project and the results were great.
I broke off a hinge screwhead in a maple cabinet door. The screw extractor was the only way I could have fixed it without having to do major surgery.
This tool was fantastic, but you have to follow the directions clearly. I had broken a #6 screw in the ash body of a guitar, under the bridgeplate. I 1st used a press and 1/4" drill bit to boor a hole in a 1/2" block of popular. I then used the drill bit to locate the broken screw and clamped the block in place. Went easy and slow with the Screw Extractor until the screw was out. I then trimed a 1/4" dowl to the correct length and glued in place. Sanded and you can barely notice it's there.
Small screw extractor
It seems to be the only show in town for removing small broken off screws, but it is very delicate. As far as i can tell the best way to get it to cut is by running it counter clockwisa. the instructions could be a lot better.
If I hadn't read the reviews I probably would have ruined it as the directions sucked. I only had to remove 3-#4 x 5/8" screws in popular. I made a guide jig - MANDITORY, ran at a very low speed and low pressure. It worked perfectly. It would be very easy to crush it in a keyed chuck. A guide jig is a must but it also adds friction and could overheat the tool if you proceed to quickley. I don't think the directions mention you must run counterclockwise.
works great when I need one
not the highest quality tool easily broken if used on a large screw at an angle, great when used straight on
This did an adequate job on broken screws in soft woods. In hard woods it has more difficulty. In fact, my bit shattered in to pieces when trying to bore out a screw that was seated deep in wood. Potentially dangerous situation.
Work great just follow direction!!
I used the 1/4" extractor to remove two broken #8 screws. I followed directions and worked slowly. The extractor worked just as it was supposed to!
Worked perfectly to remove a broken tuning machine screw from my guitar's headstock. The #3 screws are too small for other methods, besides drilling out which takes a long time and requires a lot of patience. I just wish it came in a 1/8" size.
I purchased this for a project I was working on for someone. I broke numerous screws off in an oak toy box. (Red Oak Board not Ply). I was sceptical at first because of the reviews, but decided to try it anyways. I am greatful I did, it worked just like it was intended to. I didn't have any problems. It saved me a ton of work.
Worked fine for my intended purpose.
Used it to put holes in rifle butt pad for easy access to the screws as recommended in an article in Shooting Times. Did a GREAT job!
Worked a treat
I broke the heads of 6 temporary holding screws while glueing my boat sole to the keel…doh! The screws had glued themselves in with the epoxy. I didn't want to leave them in to rust away. A normal screw extractor wouldn't work in the mess I'd got myself in. I found these on the Woodcraft site[...]. I followed the instructions – made a guide block with 1/4" hole out of 10mm ply to prevent the extractor chattering, then had a go at the problem screws embedded in the boat hull. Using a hand held drill in reverse all 6 screws came out with no further damage. This was the perfect solution to my problem, I'd highly recommend this tool to anyone who has broken the heads of wood screws.
Worked I Guess
Picked up the extractor because I had two screws break off in a maple bed leg. I was hoping for a quick fix with this tool but after the extractor broke I wound up just drilling the screw out of the wood the old fashion way. The instructions warn not to over tighten the drill chuck so I took extra care to be gentle and it still broke. I think something with a thicker walled tube would be better even if it meant a larger hole. If you are stuck give this a try but be very careful with this fragile tool.
