DeWalt Extreme Flatbit Tough Case Set Review

You can’t have an argument about which power tool brand is the best without considering DeWalt. We love their range of equipment, so testing out their Extreme Flatbit set was a must. We got hold of a set and put it through its paces on different pieces of timber.

The first thing you’ll notice is the robust case- the bits fit snugly so you don’t have to worry about them rattling about, and it looks good too. But it’s the bits themselves that are the stars of the show here and what makes this the best flat wood drill bit set we’ve ever seen.

The extra-thick shanks should resist any warping or bending through heavy use, and the clever chamfered cutting spurs are a masterstroke when you want to cut precise holes with minimal tear-out. They’re razor sharp and feel like they’ll last for years. If there was a way to reinvent the best flat drill bit, this is it.

Bosch Professional Self Cut Speed Set Review

German tool brand Bosch make all manner of equipment for keen DIYers up to seasoned professionals, so we thought they’d know how to make the best flat drill bit. We got hold of the SELFcut Speed Set and took a closer look at its features.

The bits are made from one piece of quality tool steel and the spade face features double spurs to lessen the chance of tear out on the surface of the workpiece. Bosch have refined the cutting head on these flat bits so that they stay sharper for longer and cut through wood like a hot knife through butter.

There’s one special difference that we think makes this one of the best flat bit drill sets out there- it’s the self-feeding threaded tip. Keeping a flat bit straight is one of the harder parts of drilling a good hole, so having a screw thread tip is a clever way of making sure you stay on the mark.

Umi 8 Piece Spade Drill Bit Set Review

One of Amazon’s in-house brands, Umi make some surprisingly good drill bits for the money. Ideal for the casual DIYer, their 8-piece spade bit set is just the thing for drilling wide holes in a variety of materials.

Made from heat-hardened carbon steel, which is an ideal material for the best spade bits, these are quality accessories for not a lot of money. I’m a big fan of the hexagonal-shaped shanks on these bits, they’re easy to tighten down in a drill chuck and can be more stable than a standard round shank.

I also like the soft tool roll style holder. It folds down neatly, takes up less room than a hard plastic case, and still protects the razor-sharp edges on the bits. I’m rather impressed by this set of budget spade bits.

Irwin Blue Groove 4X Metric Flat Spade Bit Set Review

One of the biggest names in US tools, Irwin is famous for their strong clamps and quality saws. This set of Blue Groove 4X spade bits are extremely well engineered and worth every penny! These aren’t budget flat bits, but professional-level tools when precision and accuracy are key.

Designed with a parabolic scoop on the business end, the shape of the bit clears out sawdust and makes cutting through wood and other materials a whole lot easier. The ends of each bit are hexagonal quick release shaped, which makes them compatible with impact drivers as well as drills.

Designed to cut through wood up to four times quicker than a standard spade bit, these are the best flat bits I’ve come across. Supplied in a handsome Irwin tool roll holder that takes up less room in your tool kit, these aren’t the most affordable bits, but they’re probably the best!

NORTOOLS Spade Drill Bit Set Review

This impressive-looking set of flat drill bits comes from NORTOOLS. They make a decent range of hand tools, and this 15-piece set is ideal for most woodworkers when they need to make wide diameter holes.

Built with extra thick shanks, these are high-performance spade bits. The carbon steel used in their construction is well suited to the job, and you get hexagonal quick-change tips on the other end. They are black powder-coated, which should help to reduce chances of corrosion, but it mainly makes them look the part!

You get a decent selection of sizes to work with, and they all come in a hard plastic case. The front size has a clear window, so you can easily see if one of the bits is missing. Compared with the Umi bits, these are much longer for driving deep holes.

Tooltime 16 Piece Flat Wood Drill Bit Set Review

We picked up this Tooltime flat wood drill bit set, because we know that you don’t always have to spend a fortune when it comes to getting the best flat wood bit set. If you’re buying for your home workshop or the odd DIY job, this set fits the bill.

We really like the wooden case- it makes the set feel premium and gives an excellent level of protection to the bits. It might not be the ideal solution for on-site jobs, but at home it’ll make a handsome display box for your best flat bits.

The hexagonal shanks will help them from coming loose in your drill chuck, but at a push you could use them in an impact driver. They aren’t re-inventing the wheel with these traditional shaped bits, and it’s probably not the best flat bit set ever made for repetitive drilling tasks, but they’re great for a hobbyist.

Flat Drill Bit Set Buyer’s Guide

Drilling large holes in wood or other soft materials is a cinch if you use flat wood drill bits. They use a spade-shaped cutting edge, guided by a point, that shaves off the layers of material to give you a quick, if not neat, hole.

When you’re buying a flat bit set, look out for high carbon steel with a thick shank. Spade bits come under a lot of pressure and create a lot of friction when they’re being used, so cheap and thin bits can warp or bend too easily.

The other thing to bear in mind is that flat bits need to be sharp and kept in good condition to work at their best. Blunt bits will cause a lot of heat and can scorch the workpiece before they cut through it, so you should opt for a case that keeps them in top condition when not in use.
