FAQ – LANCELOT® AND SQUIRE®
|Product Differences, Angle Grinder Shaft Diameters
Q: What tooth sizes does Lancelot come in and what’s the difference between them?
A:Two sizes. One has 22 teeth for a finer finish, the other has 14 teeth for more aggressive removal but slightly rougher finish. They come in several center hole sizes to suit worldwide angle grinder shafts and bottom adapters. Most of these adapters (or flanges) generally have a raised 7/8″ or 22mm shoulder and provide the option to fit the same hole center specific to other angle grinder accessories e.g., grinding wheels, wire brushes. The information below lists center shaft diameters followed by raised shoulder diameters.

Q: Are the tools safe?
Please keep in mind that you must always use caution with a power tool. The biggest danger is complacency and lack of attention to the work. We have been told many times by users that they have been lulled into a false sense of security to the danger because the tools do such a fantastic job. You must always be alert and be aware that the blades travel between 10,000 – 11,000 rpm at three times the speed of a chain saw and with twice as many teeth! Used correctly, there’s nothing better or faster on the planet.

Q: I don’t have an angle grinder. What do I need?
Single blade use only: If you only ever want to use one Lancelot or Squire blade on its own you can use a 4″ or 100mm angle grinder. The blade you select must have the 5/8″ (16mm) center hole. It is important to note that with one known exception, with a 4″ and 100mm grinder you are limited to using a single blade and cannot fit a tandem combination. They’re way too underpowered for two blades. The one exception we know of is Makita Model 9501B, 10,000rpm 4.0Amp 10mm shaft but you need to order part number 224291 – 1 inner nut to fit two blades. The nut has to be specially ordered from the Makita dealer.
For tandem, dual, double blade or two blade combinations: Again, different terms meaning the same thing! You can use any 4-1/2″ or 115m and 125mm angle grinder for any tandem combination. We recommend that you use two blades with either 5/8″, 14mm or 15mm center holes, depending on your country.
For all round versatility we highly recommend using a 4 -1/2″, 115mm or 125mm angle grinder. That will allow you to fit any tandem combination as well as using them as single blades. Nearly every 4 -1/2″, 115mm and 125mm grinder is suitable for use with our blade accessories – the exceptions are certain 4 -1/2″ Skil models with a 3/8″ center shaft. While our accessories will fit all except the Skil power units, we highly recommend angle grinders that have a paddle switch versus those with a thumb controlled on/off slide switch.
Q: Why do you prefer the paddle switch over the slide switch?
In expanding this response, paddle switch grinders are easier to operate using the on/off switch on the side of the grinder. The switch is depressed with the thumb or two to three fingers, depending on the manufacturer, versus the thumb controlled on/off slide switch located on top of the grinder body. Some manufacturers have paddle switches with a locking switch. With these machines you have two choices: 1) by depressing the paddle switch and then depressing the locking switch at the base of the grinder, you do not have to hold the paddle switch down continuously while working. Any sensitive pressure on the paddle switch then shuts the motor off or 2) you can choose to hold the paddle switch down without utilizing the lock switch. When you release pressure on the paddle switch, the motor turns off, and the accessory spins slowly to a stop. Let’s also make this clear. Contrary to some opinions, a paddle/kill switch will not bring any accessory to an immediate stop. Any and all accessories fitted to angle grinders, regardless of the type of on/off switch, will spin to a complete stop up to nine seconds after the switch to the motor is turned off. An important point is that there is no noticeable difference in performance with our blades using a grinder with either a paddle or thumb slide switch, which is why we state either style is suitable.
Q: Can you recommend any specific grinders?

Q: Why do I have to change the position of the safety guard?
Q: Can I work without a safety guard?
A: No, no and heck no! It’s not good for your health or safety. If you want to remove the safety guard for any reason, don’t use our blades. Running them without a safety guard is done so at your own risk. Please don’t under any circumstance!Q: Is it easy to change the safety guard?
A: Depending on your model grinder, it should take a few seconds with a simple turn to the left, or less than a minute if you need to make a screw adjustment. One exception is the Makita 4″ or 100mm angle grinder. Please read the next
