  2. dado • Using a dado is a very functional and strong method for connecting two pieces of stock. • It is especially useful when building cabinets or bookshelves. • The dado head is a most useful accessory for cutting grooves, dadoes, rabbets, tenons and lap joints.

  3. dado • Methods for Cutting Dadoes: There are a few different methods for cutting a dado. • Probably the most common method is to use a stacked dado head cutter on a table saw. • Usually consists of two 8" diameter, 1/8"-kerf saw blades with a number of 1/8" & 1/16" chippers in between. • By adding or removing chippers, you can obtain any width groove between 1/4" and 3/4". • Wider dadoes can be cut by making more than one pass through the saw. • A stacked dado head cutter set should only be used on a table saw or on some radial arm saws (check the tool's documentation to see if your table saw or radial arm saw will accommodate a stacked dado head cutting set).

  4. Dado blade set • This 46 tooth Dado Set is finely crafted to produce the finest cut in hardwood and veneered plywood. • Eachoutside blade has 46 teeth ground with negative relief for the smoothest cut possible. • Four – two-wing style chippers allow dados of up to 13/16" in width. • Set includes one 1/4", one 1/16" and two 1/8" chippers, shim set and carrying case. chippers shims

  7. dado Points to Remember: • When two or more chippers are used, distribute them equally around the saw. • Place the two cutting edges of the inside chippers in line with the bottom of the gullets. • This is necessary because the inside chippers are “swaged”. • This swaged part must be allowed to enter the gullet. I f this is not done then an oversized grooves/dadoes will be cut. • It isimportant that you usethe appropriate throat plate for the dado set. • When cutting a dado, try to avoid cutting any deeper than 1/3 of the way through the stock receiving the dado, to keep from weakening the stock. • For instance, when cutting a dado in a 3/4" shelf standard, make your dado cut 1/4" into the standard. • Also, there may be times when a dado shouldn't be cut the entire length of the stock. In this event, it may be best to cut the dado on a router table.

  8. Dado “wobble set” • Another option is a "wobble" dado set for the circular saw. • This is a single saw blade set on an adjustable spindle. • Adjusting the blade angle on the spindle will change the width of the dado. • While these are much cheaper than a stacked dado head cutter set, the results are far less predictable, and in my experience, rarely acceptable. • I'd resist the urge to buy a wobble dado and save my pennies for a quality stacked dado set.
