TCT Hole Saw Set, 2-Pack of 1-1/2" (38mm) Heavy Duty Tungsten Carbide

The DKIBBITHTools 2-Pack 1-1/2-Inch TCT Hole Saw Set is built to cut accurate holes through tough sheet metals and plastics. Equipped with cemented tungsten carbide teeth, these cutters solve the problem of slow drilling and ragged edges on jobs like conduit routing or pipe installation. It suits trade workers and DIY builders who handle electrical, plumbing, HVAC, or metalworking projects.

Drilling precision starts at the center, where a split point pilot bit keeps the cutter firmly in place and stops the bit from walking across smooth surfaces. The carbide teeth slice quickly through sheet stock to leave clean, burr-free edges. Inside the cup, an integrated ejection spring automatically pushes out cut slugs so you do not have to waste time prying metal plugs out of the tool between cuts.

With a 3/8-inch (10mm) shank, these hole saws mount easily into standard handheld drills, impact drills switched to drilling mode, and CNC drilling machines. They handle sheets up to 1/8-inch (3mm) thick across stainless steel, mild steel, iron, aluminum, brass, copper, FRP, and plastics. To protect the cutting edges, lower drilling speeds are recommended for harder metals, and sudden impacts or drops should be avoided to prevent tooth damage.

Keep in mind that cutting capacity is limited to a maximum depth of 0.47 inches, so this tool is made for sheet goods rather than thick stock. Long-term upkeep also requires a little extra attention: applying oil after each project and storing the cutters in the included semi-transparent plastic case helps prevent rust.

Verdict: This 2-pack is a smart choice for anyone needing clean 1-1/2-inch holes through sheet metal, pipe, or conduit. If your work involves materials under 1/8-inch thick and you want smooth cuts without bit slippage, it is a practical addition to your tool bag.

• Hole Diameter: 1-1/2 inch (38mm)
• Cutting Depth: Up to 0.47 inch
• Max Material Thickness: 1/8 inch (3mm)
• Shank Size: 3/8 inch (10mm)
• Tooth Material: Cemented Tungsten Carbide (TCT)
• Compatible Tools: Drills, impact drills (drilling mode), CNC drilling machines
• Package Quantity: 2 hole saws with plastic carrying case

A great fit if you:

• Need clean 1-1/2-inch openings for electrical conduit, HVAC, or plumbing pipes.
• Work regularly with sheet metal, stainless steel, aluminum, brass, or FRP under 1/8-inch thick.
• Want an ejection spring to quickly clear metal plugs between repetitive cuts.
• Use standard 3/8-inch chuck drills, CNC machinery, or impact drills in drill mode.

Consider something else if you:

• Need to cut deep holes into materials thicker than 0.47 inches.
• Want a variety of different hole diameters in a single kit rather than two identical cutters.

What materials can this hole saw cut?
It cuts stainless steel, mild steel, iron, copper, aluminum, brass sheet, FRP, and plastic in thicknesses up to 1/8 inch (3 mm).

What kind of drill chuck does it require?
It features a 3/8-inch (10mm) shank that fits standard drills, CNC drilling machines, and impact drills operating in drilling mode.

How do you care for the carbide teeth?
Avoid dropping the bit or applying sudden impacts, run the drill at lower speeds on harder materials, and apply oil before storing it in the included plastic case.
