Will tandem combinations fit all angle grinders?
NO. Lancelot can be paired with another Lancelot or Squire but only on 4-1/2" (115mm) and European 125mm disc grinders with 14mm (M14) or 16mm (5/8") threaded shafts. They can be matched with the same or different tooth configurations e.g. two Lancelot's 22 tooth & 22 tooth (22/22), 22/14, 14/14: Lancelot & Squire 22/18, 22/12,14/18, 14/12.

What is the best tandem combination?
The best tandem combination is to pair two blades with the same center holes, but only 14mm or 5/8" (16mm), tightened with our Universal Nut which must be used to secure any dual combination. The only other combination is to seat a 14mm or 16mm Lancelot blade on the bottom of the disc grinder's threaded shaft with a 22mm blade on top, using manufacturer's disc grinder lock nut to secure both blades. The Universal Nut is specially designed with a hexagonal head. Simply tighten blades with a 21mm (13/16") spanner, spark plug socket or adjustable wrench. It's much safer and easier than the traditional two pin spanner wrench!

Ordering System
Our simple item coding system can help you keep track of our sizes - the first number is either a 3 or 4. 3 means Squire and 4 means Lancelot, the middle two numbers refer to the arbor size and the last two numbers refer to the number of teeth. So a 45822 is a Lancelot with 5/8" arbor and 22 teeth. A 31412 is a Squire with 14mm arbor and 12 teeth. The 14mm tools are primarily for European angle grinders.

Seven (7) Tandem Combinations
These combinations can be fitted to angle grinders with 5/8" (16mm) and 14mm threaded shafts. There are 7 different kinds of tandem combinations possible and they are listed below. They come in 5/8" arbor and 14M 14mm centers for European models.

Combination #1: Two (2) 22 tooth Lancelot's Model 45822 or 41422. This combo is a racing fast shaper and remover. With 44 teeth revving around at up to 13,000rpm, these blades do an awesome job as they slice, cut, carve and shape. The smooth finish is the result of the smaller tooth pitch. Effortless and safe. Used individually, the 22 tooth is our most popular blade and great for detail work.

Combination #2: Two (2) 14 tooth Lancelot's Model 45814 or 41414. This is our most aggressive and popular combination for major mass removal. With 28 large pitch (3/8") teeth hogging out material, time on any project will be greatly reduced with this beast. If you want to just get the wood out of the way in a hurry, this is definitely the combination to use. Two 14 tooth cutters removes more wood faster than any other combination.

Combination #3: One (1) of each 14 tooth and 22 tooth Lancelot. Model 45814 and 45822 or 41414 and 41422. With this versatile combination, you get the best of both worlds. Mass removal performance is excellent and if the 22 tooth blade is mounted over the 14 tooth, (closest to the universal nut), the finish is finer in convex and sweeping shaping. This versatile combination also provides two tooth choices when used individually for detail work.

Combination #4: One (1) of each 22 tooth Lancelot and 18 tooth Squire. Model 45822 and 35818 or 41422 and 31418. This is the offset fine tooth combination mounting the larger Lancelot first with Squire on top fastened with the Universal nut. When holding the grinder with the blades at between 25 to 30 degrees to the material, you have 40 teeth sweeping or raking material away sideways or in downward strokes. Also removes material in slice, plunge and straight cuts but leaves a step or bench shape with each pass. Best used for convex shaping e.g. removing the sides of a bowl, leaving a fine finish. Also great individually for detail work.

Combination #5: One (1) of each 22 tooth Lancelot and 12 tooth Squire. Model 45822 and 35812 or 41422 and 31412. This is the offset fine and course tooth combination mounting the fine tooth Lancelot first with the course tooth Squire on top. When holding the grinder with the blades at between 25 to 30 degrees to the material, you have 34 teeth sweeping or raking material away sideways or in downward strokes. Will also remove material in slice, plunge and straight cuts but leaves a step or bench shape with each pass. Best used for convex shaping in larger works. Rapidly removes material but leaves a course finish. Also great individually for detail work.

Combination #6: One (1) of each 14 tooth Lancelot and 12 tooth Squire. Model 45814 and 35812 or 41414 and 31412. This is the offset course tooth combination mounting Lancelot first with Squire on top. Again, when holding the grinder with the blades at between 25 to 30 degrees to the material, you have 26 teeth sweeping or raking material away sideways or in downward strokes. Will also remove material in slice, plunge and straight cuts but leaves a step or bench shape with each pass. This is our most aggressive course tooth offset Lancelot/Squire combination and removes material incredibly fast for convex and surface shaping in large works where finish is not important.

Combination #7: One (1) of each 14 tooth Lancelot and 18 tooth Squire. Model 45814 and 35818 or 41414 and 31418. This is the offset course/fine tooth combination mounting the course tooth Lancelot first with the fine tooth Squire on top. Again, when holding the grinder with the blades at between 25 to 30 degrees to the material, you have 32 teeth sweeping or raking material away sideways or in downward strokes. With the aggressive Lancelot as the workhorse combined with the fine finish of Squire, stock removal is rapid leaving a relatively smooth surface. The choice may come down to the number of teeth you want and how you want to use them individually for detail work. In this combination, Lancelot has a larger kerf and course teeth while Squire has a smaller kerf and fine teeth.
