Carbide Tipped Teeth: Tungsten carbide (TCT) teeth cut up to 30% faster and last 10X longer than bi-metal hole saws, per Unibor's category page copy.
Deep 1" Depth of Cut: 1" depth of cut (per price-file SKU descriptions, e.g. 'UNIBOR HOLE SAW 2" X 1" DOC'), roughly 5x deeper than the Speedcut 3/16" line, for thicker plate/structural stock.
Multi-Metal Capable: Rated by Unibor for stainless steel, construction steel, and truck chassis work, as well as electrical applications.
Spring-Loaded Core Ejection: A spring-loaded center drill ejects the slug/waste core automatically for faster repeat cuts.
Wide Diameter Range: Price file lists this line from 9/16" up through 4.1/2" diameter, the largest range of any Unibor hole saw family in our catalog.

JLT #180A-M2 Pneumatic Panel Flattener Customer review image

Mike Yaross Field Verified

Just what I needed

"Saw works great. Just what I needed. You may want to update the specs though. It says 110v but it’s 220v. I don’t think it will an 10” saw blade either. Haven’t tried but I don’t think it’s set up for one like it says. Ordering process was nice and easy. Thank you."

FRANCISCO, Shop Manager Field Verified

Built for 24/7 Production

"Got the JLT #717C for our shop and it’s an absolute beast for narrow stile doors. The 2-second squaring cycle is legit—we’re easily pushing 100+ perfect doors a day now without stressing over glue joint alignment. Setup is super fast with the pin system, and the heavy-duty build takes daily abuse without losing accuracy."

Heavy Duty & Precise

"Brought this Jet 16" x 40" Engine Lathe into the shop recently and it’s an absolute beast. The 3-1/8" spindle bore is exactly what we needed for turning larger bar stock, and the geared head runs incredibly smooth from 25 all the way up to 1,800 RPM. It handles our heavy daily metalwork without breaking a sweat, and you can see how solid the build is right in the photo. If you need a reliable 3-phase lathe that holds tight tolerances all day, grab this bad boy. Worth every penny."

Frequently Asked Questions

It means two metals are fused together: hardened high-speed-steel teeth welded onto a flexible alloy-steel body, so the saw stays sharp while resisting cracking.

Yes, a bi-metal hole saw cuts mild steel, aluminum, brass, and thin stainless up to roughly 3/16 inch wall thickness; thicker or hardened steel calls for a carbide-tipped saw or annular cutter instead.

Bi-metal saws use HSS teeth on a flexible steel body for forgiving, general-purpose cutting, while carbide-tipped saws stay sharp far longer in abrasive or hardened material but are more brittle under side impact.

Run the drill at low RPM, keep the cut lubricated with cutting fluid, and clamp the workpiece securely so it cannot spin when the saw breaks through.

Yes, bi-metal hole saws are dual-purpose and cut cleanly through wood, plastic, and thin metal with the same blade.
