what type of bit to use to get a clean hole in pine

Y'all have a few options when y'all need to cutting a pigsty. What you choose depends on how big you need the diameter, how clean you need the cut, and how much you want to spend. Hither are 4 of the near common methods to cut perfect holes in forest

1 of the simplest methods for cutting a hole any size is to use a jigsaw. The drawback here is that the saw can drift while y'all are cutting and getting a perfect circle is nearly impossible. And while the result might be proficient enough depending on what you are building, in this video I want to focus on methods that will produce a perfect circle.

Cut holes with a Jigsaw is a unproblematic method…

…but it's about impossible to make perfectly round holes.

Spade $.25

A spade bit has two cut edges and a heart point.

The least expensive method is a spade or paddle bit. These are more often than not used in crude structure projects where the quality of the cutting isn't critical, say drilling holes in wall studs to run electrical wire. That said, y'all might be surprised how make clean they will cut holes in solid lumber as long as you drill slowly and use a backer board. In fact, the cuts I get with them frequently rival the quality of a Forstner flake.

…and plywood.

One drawback to spade bits it that they aren't available for making large holes. I recollect the biggest diameter I ordinarily encounter is 1 ½". But a set up of spade bits is cheap and worth having in the shop.

Frostner Bits

A Forstner bit makes clean cuts with apartment bottoms.

A large jump in quality is the Forstner scrap. These are definitely the best choice for woodworking projects. They bore super clean cuts with minimal tear-out. Since they produce a flat bottom, they are also useful if yous only need to drill through partway through a board. And you can observe them in larger diameters than spade $.25: I've seen them up to 4" and yous can probably discover even bigger ones.

Use slower speeds on your drill for bigger $.25.

Of class the biggest drawback to Forstner bits is their cost. Depending on what brand you buy, they can exist very expensive. I recommend getting a multi-bit kit. I bought a set at Costco for $50 over 15 years agone and nevertheless go great results. And I just saw this 14 piece gear up on Amazon for a fiddling less than $50. If you are a weekend woodworker, an affordable gear up will work fine.

Hole Saws

Hole saws in a multifariousness of diameters.

Hole saws are available in even larger diameters than Forstner bits and they can exist a little cheaper. Unlike spade and Forstner $.25, they cut out plugs rather than bore holes.

Rather than deadening through wood like the other bits…

…hole saws remove circular plugs.

As with the spade and Forstner bits, you will have the best results using a drill press. If you lot don't have one, be sure to clamp your workpiece downwards. Information technology will be impossible to hold it by hand. Drill slowly raising the saw up and down to clear out the sawdust. If information technology stops cutting, check to run across if the teeth are clogged.

If you don't accept a drill printing, be sure to clamp your work piece down.

Circle-Cutting Router Jig

All three of the previous techniques rely on having to buy a special bit or saw for each size pigsty y'all need to cutting. This can go pricey. And what if yous demand to cutting a really large hole, say 10" in diameter? All you need is one tool: a router. This is a keen way to cut pocket-sized or big holes. The main drawback is that the setup time takes longer than the other methods.

A circle cutting jig for your router will produce round holes any size.

How to make a circle-cutting jig for a router

1. Remove the base of your router.
2. Attach a bit of plywood to the base.
3. Insert a straight bit
4. Measure the radius of the hole you need.
5. Mark your radius altitude from the chip to a indicate on the plywood base.
6. Drill a screw into this betoken and screw this into your workpiece and a scrap backer board.
7. Drop the router into your workpiece and rotate it around the screw to cut the hole.

Replace your router'due south base with a strip of plywood.

Drilling a hole where the pivot bespeak will exist.

Afterwards screwing the base to your workpiece, driblet the router into the wood and started revolving around the screw.

Like everything else in woodworking, at that place are options for every task. These are my favorite ways to cut perfect holes in woods. Mostly I want to emphasize that you can accomplish just about any woodworking goal with modest tools. My advice is always to buy a new tool or upgrade what you have merely when you lot simply can't accomplish something with what you lot take.
