LENOX Tools Bi-Metal Speed Slot Hole Saw Set

The Verdict

The LENOX Tools Bi-Metal Speed Slot Hole Saw Set has been sitting at a 4.5-star average across 225 ratings for a reason — it actually delivers on the “speed” promise. But let’s talk about whether it’s the right hole saw set for your projects before you drop money on it.

What You Actually Get

The set includes 11 hole saws in metric sizes from 3/4" up to 3", covering the most common diameters for electrical boxes, door hardware, and pipe penetrations. You also get a 1/2" hex shank arbor with a pilot bit and a blow-molded case.

The arbor is worth calling out specifically: it locks into any standard drill or impact driver without needing a separate chuck key or adapter. That’s a small convenience that saves real time on the job.

Performance: Where the Speed Slot Actually Matters

The Speed Slot design is not marketing fluff. The slots in the saw body break the cutting edge into segments, which serves two practical purposes: faster chip evacuation and reduced friction. In wood, that translates to noticeably quicker cuts with less heat. In metal, it prevents the saw from grabbing and walking across the surface.

One buyer put it plainly: “I’ve burned through cheaper hole saws in a single afternoon. This one cut through a solid core door and kept cutting. The slots really do make a difference.”

The bi-metal construction (M42 high-speed steel teeth welded to a tough steel body) means the teeth hold an edge far longer than the carbon steel sets you’ll find at the big-box store. For drywall, plywood, and even mild steel up to 1/8" thick, this set handles it without complaint.

What Buyers Consistently Praise

Across the reviews, three themes dominate:

1. Cutting speed — users consistently note faster cutting than previous sets they owned, particularly in wood
2. Chip removal — the slots genuinely eject sawdust instead of binding the cut
3. Arbor compatibility — the hex shank works with impact drivers, which many buyers specifically wanted

One reviewer summed it up: “This is the first hole saw set I’ve owned where the saw doesn’t overheat on a 2x4. The slots pull the sawdust out like a vacuum.”

Where It Falls Short

No product is perfect, and this set has two honest weaknesses.

The case is cheap. It’s thin ABS plastic that will survive a garage shelf but won’t hold up to being thrown around a truck bed daily. If you’re a contractor, budget for a separate storage solution.

The pilot bit is the weak link. Several buyers report the pilot bit dulls noticeably faster than the hole saw itself, especially when hitting nails or staples in framing lumber. It’s replaceable, but it’s an extra part to track down.

Also note: the 3" saw is the largest included, so if you need anything bigger for door hardware or ductwork, you’ll be buying a separate saw anyway.

Who Should Buy This

Buy it if: You’re a DIYer or serious homeowner who needs a reliable, versatile set for electrical work, door installs, or general remodeling. The Speed Slot design genuinely saves time, and the range of sizes covers 90% of common projects.

Skip it if: You’re a professional running hole saws daily through nail-embedded lumber or thick steel. You’ll want a higher-end set with replaceable arbors and a tougher case — and you’ll burn through the pilot bits on this set faster than you’d like.

FAQ

Q: Will these cut through metal? Yes, but stick to mild steel up to about 1/8" thick. For thicker steel, you’ll want a dedicated metal-cutting hole saw with variable speed control on your drill.

Q: Does the arbor fit a standard 3/8" drill? Yes. The 1/2" hex shank fits any standard drill chuck, and the pilot bit is included and pre-installed.

Q: Are replacement pilot bits available separately? Yes, LENOX sells them as a replacement part. They’re inexpensive, but you’ll want to have a spare on hand if you’re cutting through old framing.

The Verdict

Rating: 4.6/5

The LENOX Bi-Metal Speed Slot set earns its strong rating. It cuts faster, lasts longer, and covers more project scenarios than comparably priced sets. The case and pilot bit are the only real compromises, and neither is a dealbreaker for the average buyer.

Buy it if you want a dependable, fast-cutting hole saw set that won’t leave you frustrated halfway through a project. Skip it if you need heavy-duty daily professional use — but for everyone else, this is the set to grab.
