Select Lowe's Stores: 13-Piece Spyder Bi-metal Arbored Hole Saw Kit Set

If you found the 11pc set and it rings up $69.98, then you got the wrong set.

There is a 11pc set, and it has only 11 pieces. It is Item #1483288 Model #600886 and is indeed priced at $69.98.

This set is a 13pc set, it is labeled as a 11pc plus two bonus. It is Item #4353274 Model #600886 + 2 BONUS, yes the model number actually contains the "+ 2 BONUS" suffix.



In the attached picture the 11pc + 2 bonus is a bigger box and the inside arrangements are different. In south Florida I found one store priced at $12.47 (but couldn't find any in stock but BS said 5, looked at the clearance area and in upper shelves). Another store has 2 but at $24, so I bought one.

Different applications and requirements.

A spade bit, will chew through the wood completely and make a hole as it spins. The inside of the hole is completely tore up and most likely when it makes it all the way through, the back side of the wood will be a bit messy with splinters. It is used to make holes quick like feeding wires and pipes through joists and studs. The cut holes are rough and do not need to be perfectly orthogonal to the materiaL You most likely will then cover them with finished walls or ceiling boards and not have to look at it again. advantage is it is quick, and can be used with an impact driver for tighter space and easy bit change.

A Forstner bit, makes a round clean cut through the material, most times wood. It cuts slower, but the hole it makes is precise, Most of the time, a Forstner bit is used if you really do not want to cut all the way through the material, but only needs a round recessed, an example of that is the mounting recess hole for a cabinet hinge. You want a nice round hole say 3/8" deep into a 3/4" thick board, and you need the bottom of that hole to also be perfectly flat. A spade bit would have made a crater if you drill it half way through.

A hole saw makes a hole but cutting through the material like a saw going in circular motion. It does not chew up all the wood inside the hole like a spade or Forstner bit. When it's done, you end up with a cut end inside the hole saw that is a round plug. If you run the hole saw half way into the material, stop and withdraw, the middle piece is still there, connected to the rest of the material. If you then jam a flat head screwdriver into the seam and pry, the half cut piece will most likely break off, and if you then pull it out, you will see the bottom of it is uneven, it breaks wherever it breaks according to the wood grain.
