Mollom 7-1/16" (180mm) Carbide Hole Saw — Heavy-Duty 40 TCT Teeth, Includes 2 Pilot Bits

Mollom's 7-1/16" (180mm) carbide hole saw is a heavy-duty, tungsten-carbide tipped cutter designed to bore large, clean holes through hard metals and general sheet materials while including two pilot bits for fast, burr-free results.

This high-capacity hole saw brings industrial-strength cutting to workshop and jobsite use. Built with 40 tungsten-carbide teeth and a titanium-plated, cemented-carbide finish, the 180mm cutter provides long-lasting edge retention and improved wear resistance compared with conventional bi-metal hole saws. The kit ships with two pilot bits and a protective case, making it ready for bench drills, magnetic drills, gun drills and percussion drilling setups.

What materials can this 180mm carbide hole saw cut through?

The Mollom 7-1/16" hole saw is optimized for cutting through hard metals and general sheet materials. It performs reliably on stainless steel, iron, cast iron, square tube, and F.R.P., and also works on softer substrates like wood and regular metal plates. Avoid using it on masonry, ceramic tile, or natural stone, as the carbide teeth are not intended for those materials.

• Stainless steel sheets up to thin-gauge thicknesses (can bore into 0.1-inch stainless in many cases)
• Carbon steel, iron, cast iron and square tubing
• Fiberglass reinforced plastics (F.R.P.) and wood
• Not suitable for concrete, tiles or stone

How fast and precise is the cutting performance?

The tool's 40 tungsten-carbide teeth and high-hardness, titanium-plated cemented-carbide construction deliver faster cutting and longer service life versus standard bi-metal hole saws. The body design and spring-loaded pilot bit eject the slug and reduce burrs, producing cleaner holes with less finishing work.

• 40 TCT teeth for rapid material removal
• Spring-loaded pilot bit that ejects the cut slug immediately
• Titanium-plated carbide teeth for sustained sharpness and rust resistance
• Typical result: faster cuts with reduced burring compared to twist drills

Will this hole saw fit my drill and how deep will it cut?

The cutter uses a 10mm (3/8") shank diameter compatible with most drill chucks and arbors. It provides a 25mm (1") cutting depth, making it suitable for through-holes and many panel-thickness applications. The package includes both a titanium-plated pilot bit and a stepped pilot bit so you can choose the best pilot configuration for your tool and material.

• Cutting diameter: 7-1/16" (180mm)
• Shank diameter: 10mm (3/8") — fits common chucks and arbors
• Hole saw depth: 25mm (1")
• Includes two pilot bits in protective, oiled plastic casing

How durable is this cutter and what maintenance does it need?

Mollom's hole saw uses tungsten-carbide tipped cutters and high-grade cemented-carbide teeth with a titanium finish to resist wear and corrosion. Compared to standard bi-metal designs, it delivers a significantly longer service life in demanding metal-cutting tasks. Regular cleaning, light lubrication, and storing the bits in their supplied cases will keep cutting performance consistent.

• Carbide tips provide extended life—reported to last substantially longer than bi-metal equivalents
• Titanium plating and oil coating help prevent rust during storage
• Recommended: use cutting fluid on metals and clear debris frequently
• Replace worn pilot bits to maintain clean starts and minimize wobble

Who this tool is for: the Mollom 180mm carbide hole saw is intended for professional fabricators, metalworkers, maintenance technicians, and serious DIYers who frequently cut large-diameter holes in hard metals and sheet materials. If you need cleaner, faster large-hole cutting with extended cutter life and compatibility with common drill platforms, this kit offers a ready-to-use solution. Avoid it if your work focuses on masonry, tile, or stone, where specialized masonry bits are required.
