TCT Hole Saw Kit 12PCS for Hard Metal - Tungsten Carbide Tips

In this review the ASNOMY TCT hole saw kit earns a recommendation for metalworkers and serious DIYers who need a compact set of cutters built to handle hard metal. The main reason to buy is the set's use of Tungsten Carbide Tipped cutters combined with titanium-plated pilot drills, which deliver fast, clean holes in mild steel, stainless sheet, and similar materials. The kit arrives in an aluminum case and includes multiple sizes that cover common hole requirements without the bulk of larger industrial sets.

Key Features

• TCT carbide teeth: The tungsten carbide tipped cutters stay sharp for cutting hard metals and produce cleaner round holes than standard HSS hole saws.
• Three-blade tooth design: The outer, middle and inner blade arrangement increases cutting efficiency and reduces chatter when drilling through steel and iron.
• Titanium-plated pilot drill: High-grade M2 (6542) pilot bits help start holes accurately and resist rust thanks to the titanium plating.
• Compact 10-piece sizes: Range of diameters from 5/8 in to 2-1/8 in covers typical electrical and plumbing penetrations without excess overlap.
• Ready-to-go kit case: The set ships in an aluminum box with extra pilot bits, hex wrenches and oil on each cutter to prevent corrosion in storage.

Who It's For

This kit is best for tradespeople, fabricators and experienced DIY users who frequently cut holes in sheet metal, stainless plate, square tube or thin cast iron and want sharp, carbide-tipped cutters in common sizes. It suits use on bench drills, magnetic drills, gun drills and hand-held electric drills fitted with the listed shank.

Less suitable users include those who primarily cut masonry, concrete, tile or stone, since the set is not rated for those materials. Casual users who rarely cut metal might prefer buying single cutters or a smaller set to save cost and storage space.

Pros & Cons
