ASNOMY Tungsten Carbide Tipped Hole Saw 5-1/2" (140mm) — 1" Depth, Titanium-Plated for Hard Metal

ASNOMY 5-1/2" Tungsten Carbide Tipped Hole Saw is a 140mm TCT cutter built to bore clean, precise holes in hard metals and thick sheet material with reduced chipping and long tool life.

This heavy-duty hole saw combines tungsten carbide tipped (TCT) cutters with a three-blade tooth geometry and titanium plating to tackle stainless steel, iron, cast parts and other tough metals. The 5-1/2 inch (140mm) diameter and 1 inch cutting depth are sized for larger conduit, pipe and fixture openings; a 12mm (15/32") shank and included pilot bits make it compatible with bench, magnetic and handheld drills. Each cutter ships in a protective plastic case with two titanium-plated pilot drills pre-oiled to resist rust.

How does this hole saw handle hardened steels and thick metal sheets?

The tungsten carbide tips and high-grade cemented carbide teeth deliver high hardness and improved wear resistance, so the cutter stays sharp longer under heavy load. The three-blade design spreads cutting forces and reduces heat buildup for more consistent performance when penetrating tough alloys.

• TCT (tungsten carbide tipped) teeth for hard-metal durability
• Three-blade tooth layout for efficient chip evacuation
• Titanium plating to resist corrosion and reduce friction

What drill types and setups are compatible with this 140mm cutter?

The cutter is made to work with multiple drilling platforms including bench drill presses, magnetic base drills, and portable handheld drills. The 12mm (15/32") shank fits common chucks, and the included pilot bits stabilize the cut to prevent wandering on flat or curved surfaces.

• Fits bench, gun, percussion and magnetic drilling machines
• 12mm shank diameter for standard chucks
• Two pilot drills included for reliable centering and faster starts

What size, depth and accessories are included in the package?

This item is a single 5-1/2" (140mm) hole saw with a 1" cutting depth and a 15/32" (12mm) shank. The package contains one T.C.T hole cutter and two titanium-plated pilot drills, each piece stored in its own oiled plastic case to prevent rust during storage and transit.

• Cutting diameter: 5-1/2" (140mm)
• Cutting depth: 1" (25mm) — suitable for many sheet and plate jobs
• Includes 1 cutter + 2 titanium-plated pilot drill bits in plastic cases

How should I use and maintain this hole saw for best longevity?

Use moderate feed pressure and steady speed, backing out periodically to clear chips when cutting thick or sticky metals. Keep the pilot bit sharp and lightly lubricate the cut area for cooler cutting; store the cutter in its protective case with the included oil coating to prevent corrosion between jobs.

• Use cutting lubricant for stainless and alloy steels
• Retract frequently to remove chips and dissipate heat
• Keep stored oiled in the plastic case to avoid rust

Who is this for: The ASNOMY 5-1/2" TCT hole saw is aimed at fabricators, maintenance technicians, electrical and plumbing contractors, and metalworkers who need a larger-diameter cutter for clean, reliable holes in hard metal and sheet stock. It suits shop environments and fieldwork where compatibility with bench drills, magnetic drills and handheld units matters; it is not designed for masonry, concrete, tile or stone.
