Tungaloy TungMeister exchangeable-head end mill series reduces tool change

A quick-change arbor sleeve quickly releases the saw after drilling, and their open-end design allows you to ram it backwards against the base to eject the plug in seconds. This arbor design also makes it easy to switch between saw sizes as you go, saving even more time.

If you don’t already have an arbor on hand, make sure you choose a saw or kit that includes one. If you do have an arbor already, you can usually get more bang for your buck by going with a saw that doesn’t include one.

These features make the Disston QuickCore saws especially useful for those who use hole saws frequently, since that extra time per plug can really add up over the course of a workday.

If you want to create perfectly round holes in wood, metal, or plastic, you’re going to need a hole saw. These cylindrical saws are powered by any corded or cordless drill, and their hollow shape allows you to remove the waste material in a single piece, or “plug,” which drastically cuts down on sawdust cleanup.

Boasting 28 individual saw sizes, this Milwaukee kit is prepared for a wide range of projects and tasks. A sturdy molded case keeps your saws protected when not in use, and their nested design allows the kit to take up minimal space in your toolbox or on your workbench.

To ensure that you choose the most effective hole saw for you and your projects, keep these factors in mind before purchasing.

Its carbide teeth are strong enough to be safely and efficiently used on metal surfaces, and their ejection springs easily pop out plugs when you’re finished with a cut. A raised shoulder prevents you from over-drilling too, which is always a nice perk.

A pilot drill bit ensures that the saw is perfectly centered before it makes contact, reducing the chances of the blade skipping or walking across your workpiece. Hole saws come in a wide range of diameters, too, so whether you’re cutting a ¾-inch hole for conduit or a six-inch hole for can lights, you can find one that suits your needs.

STINGER™ Mach-Blue™ armor plated HSS drill bits are available in a 10-piece kit with an MSRP of $39.98.

The bits mark the debut of Spyder's proprietary Mach-Blue™ armor plating, an ultra-hard surface plating that helps retain sharp cutting edges and reduce heat build-up, resulting in faster cuts and exceptionally long life. The Mach-Blue™ plating gives the bits an eye-catching, iridescent blue finish that performs like nothing else on the market.

Other features include a self-centering split point design that won't walk or wander, even on pre-hardened or curved surfaces. The impact-rated 1/4" speed hex shank allows the bit to be used in quick-change impacting drivers as well as conventional three-jaw chucks in hand drills and drill presses. The high-performance, jobber-length bits are made in the USA.

I used hole saws extensively when working as a commercial carpenter, and have cut hundreds of holes in office desks, doors, and drywall. I kept this experience in mind when assembling this list, making sure to include brands that I’ve come to trust over the years, as well as avoiding frustrating design components and brands with poor quality control reputations.

Greenlee has been a favorite of professional tradespeople for years, and these carbide-tipped saws are a great example of why they’re so popular. This carbide construction allows them to power through metal, and also cuts down on annoying squealing and saw chatter.

Despite the budget-friendly price, this Bosch kit still packs a ton of value. In addition to the high-quality construction found in Bosch products, you’re also getting two universal arbors and a steel pilot bit for maximum control and stability.

"Mach-Blue™ bits are engineered to drill quickly and cleanly over and over," Tyson said. "They cut cleaner and last significantly longer than other high-quality titanium plated or cobalt bits, even when drilling dense, thick metal."

The new HSS bits join Spyder's other STINGER™ drilling accessories, which include auger, power and spade bits. The HSS bits are Spyder's first-ever standard-size drill bits, but there is nothing standard about their performance, said Matt Tyson, Senior Product Manager at Spyder.

STINGER™ Mach-Blue™ HSS bits have been shown to drill up to 100 times more holes than titanium or black oxide drill bits before a replacement is required, and to make holes up to eight times faster than titanium drill bits.

If you’re primarily using your hole saw to create holes for door locks or knobs, and don’t need the variety of a large kit, this Lenox Tools model is a great choice.

The staircase-style speed slot will help cut down on plug removal time too. It’s not cheap, and you’ll need to supply your own arbor, but if you have the need, this saw could be a great investment.

Dislodging the plug inside the saw after cutting can be a frustrating and time-consuming task, so look for a saw that allows you to clear it quickly—some saws have large cutout slots that you can poke a screwdriver through, and others even feature spring-loaded ejection mechanisms.

Hole saws are typically made with either bimetal or carbide blades. Bimetal saws are more popular because they’re compatible with a variety of materials and cut quickly while resisting wear and tear.

STINGER™ Mach-Blue™ armor plated HSS drill bits and other additions to the STINGER™ line of drilling and wood-boring tools will be available online at Lowes.com and rolling out to Lowe's stores nationwide this month.

Beneath the plating, the bits are constructed of heat-treated M-Series tool steel, known for its durability and resistance to breakage. They are optimized for use in wood, steel, mild steel, aluminum, stacked materials and other tough-to-drill alloys.

Carbide saws are more robust and can withstand higher temperatures, making them suitable for use on heavy-duty materials like stainless steel. Diamond-tipped hole saws are also available for use with ceramics, glass, and stone.
