TCT Hole Saw Kit 7PCS 5/8ft-1-3/4ft for Hard Metal - Heavy Duty

Our review of this 7-piece TCT hole saw kit finds it best suited for tradespeople and serious DIYers who need to cut clean holes through hard metals. The single biggest reason to consider this set is the use of tungsten carbide tipped teeth combined with a three-blade design, which produces fast, accurate cuts in stainless steel and mild steel that many bi-metal options struggle with. The kit ships with extra titanium-plated pilot bits and an aluminum case, making it a practical choice for workshop or on-site use.

Key Features

• TCT Carbide Teeth: Tungsten carbide tipped cutters deliver durability and aggressive cutting action for hard metal work.
• Three-blade Design: Outer, middle and inner blades work together to produce sharper, more efficient cuts and cleaner hole edges.
• Range of Sizes: The set covers common hole sizes from 5/8 in to 1-3/4 in, useful for plumbing, electrical and metal fabrication tasks.
• Titanium-plated Pilot Bits: High-grade M2 pilot bits with titanium plating improve centering and resist rust during repetitive drilling.
• Ready-to-go Case: All pieces come in an aluminum box with oil coating on bits to prevent corrosion during storage and transport.
• Versatile Compatibility: Designed for bench drills, magnetic drills, percussion drills and handheld electric drills for varied workshop setups.

Who It's For

This kit is aimed at metalworkers, fabricators, plumbers and electricians who regularly cut holes in stainless steel, mild steel, iron and similar sheet metal. The aggressive carbide teeth and 1 in cutting length make it a practical choice when durability and consistent hole quality matter on jobsite projects.

It is less suitable for users who primarily cut masonry, tile or stone, since the cutters are not rated for concrete or ceramic. Hobbyists who only drill occasional thin wood or plastic holes may find the set overbuilt for their needs and could opt for a smaller, cheaper bi-metal set instead.

Pros & Cons

Pros

• High cutting performance on hard metals thanks to TCT carbide tips.
• Three-blade geometry yields cleaner holes and improved cutting efficiency.
• Includes spare titanium-plated pilot bits and a durable aluminum case for storage.

Cons
